Had submitted a paper to ACL ARR May 2026 cycle. Unfortunately, none of the reviewers acknowledged the rebuttal during the author-reviewer discussion I am curious to know from people who had volunteered to review papers this cycle- are you still able to update the ratings, or even your review based on the rebuttal? Also is there any meta-reviewer discussion going on? submitted by /u/Forsaken-Order-7376 [link] [留言]

Hi, I’ve been doing some work in the continual learning space and wanted to share an open-source framework we put together called Coincidex, along with some architectural insights and failure modes we found along the way. Most conventional approaches to sequential task learning rely heavily on replay buffers (which introduce severe memory/privacy overhead) or complex, hand-tuned task masks. We wanted to see if we could bypass both by relying entirely on a context-driven task similarity layer to handle data routing dynamically. The Approach: Instead of caching historical samples to prevent catastrophic forgetting, the framework drops in as a single layer swap. As sequential data streams in, it computes a task-similarity matrix on the fly, routing the data paths based on that context. Research Insights & Trade-offs: We spent a lot of time benchmarking this against baselines, and here is what actually happened in practice: Where it succeeds: The dynamic routing handles clean task boundaries surprisingly well. In small-scale continual vision setups, it achieves graceful transfer without the need for manual mask tuning or storing old data. Where it breaks (The Failure Modes): We aren't going to overpromise here—the similarity layer has distinct limits. On highly chaotic, long-tail task sequences with massive distribution shifts, the routing model struggles to maintain stability compared to a heavy replay-buffer baseline. Why we are sharing it: We built this as a lightweight alternative for setups where memory or privacy constraints make replay buffers impossible. We would love to get the community's eyes on the routing architecture, specifically on how we might tackle the failure modes in rougher task sequences, or thoughts on visualizing the similarity matrix at different checkpoints.

I worked on this project ( https://github.com/workofart/harness-training ) for the past few months to reframe "Agent-driven Self-improving Harness" to "Harness Training". The idea is simple, the harness is trained once with a frozen task LLM against a given task environment. Then you can then swap out the task LLM to any model and evaluate the "frozen trained harness" with any task LLM on any new task environment. Since this was a general problem, I took the chance to create a general PyTorch-like training framework. Right now, you can train with any OpenAI-compatible API for interfacing with the task LLM and train against Terminal-Bench or SWE-Bench tasks, but you can easily extend it to support any task environments. criterion = StrictPareto() optimizer = GreedyMonotonic() trainer = Trainer( config_path="config/train_harness.yaml", estimator=AgenticEstimator( backend=CodexAgentBackend(...) ), criterion=criterion, optimizer=optimizer, ) for loss in trainer.epochs(30): # Records the baseline-vs-candidate verdict loss.backward() # Optimizer either fast-forwards the candidate change (git commit) as a new baseline or rejects it (preserved as git ref) optimizer.step() I wrote a blog post ( https://www.henrypan.com/blog/2026-07-18-harness-training ) on this journey, including (but not limited to): results from using this harness training framework to improve general capabilities across many task LLMs to beat Terminal Bench 2.0 (Terminus Harness) and also transfer learnings towards better task-solving abilities in unseen task environments (e.g. harness trained on SWE-Bench tasks solving Terminal Bench tasks). how this framework is built learnings on what was missing in my initial version of the project (hint: determinism) Any feedback is appreciated. Thanks! submitted by /u/Megadragon9 [link] [留言]

Why we built Veridexa Many document analysis workflows still rely primarily on OCR OCR is useful for extracting text, but it cannot answer one important question: Does this document show signs of fraud or manipulation? That question led us to build Veridexa. The problem Organizations receive thousands of digital documents every day: Passports National IDs Academic certificates Bank statements Employment documents Invoices Reading the text is only one part of the process. The difficult part is detecting manipulation, inconsistencies, forgery, or suspicious evidence before making a decision. Our approach Instead of relying on OCR alone, Veridexa combines multiple evidence sources into a single fraud assessment. The platform analyzes: OCR extraction Metadata Image forensics Security features Document structure Cross-evidence consistency The result is an explainable decision instead of a simple confidence score. Explainable decisions Every analysis ends with one of three outcomes: ACCEPT MANUAL REVIEW REJECT Each decision is accompanied by supporting evidence so reviewers understand why the system reached that conclusion. Public benchmark We also believe AI systems should be transparent. For that reason Veridexa publishes a public benchmark together with methodology and performance reporting instead of asking users to trust marketing claims. API-first Try the public demo, explore the benchmark, or integrate the API. Feedback from developers and security professionals is always welcome. https://veridexa.io Developers can integrate Veridexa into their own applications using our API while organizations can use the web platform without writing code. We'd love your feedback We're continuing to improve the platform and would genuinely appreciate feedback from the developer community. Website: https://veridexa.io

So, I just read LeCun's interview with Nebius Science. I feel he had some cool points about LLMs being able to answer things, but not literally understand the physics of the physical world. (Like, being able to explain a task and actually performing it are two completely different things.) But I wanted to get opinions on what others thought of his solution to the problem. He thinks JEPA could be the solution. But it made me think about whether JEPA is genuinely the architectural solution to this, or if we’re just looking for a "magic bullet" that doesn't exist yet in our toolbox I have the link here: https://nebius.science/stories/meet-yann-lecuns-lab-and-the-ai-world-of-2030 submitted by /u/ConsciousGreenPepper [link] [留言]

Introduction At recent technology conferences, one topic has caught my attention: every year, more health-focused devices, sensors, and applications appear. Smartwatches track heart rate, smart scales measure body data, glucose monitors record blood sugar levels, and apps help users track sleep or nutrition. Today, the amount of information we can collect about our own bodies is enormous. This article was inspired by an everyday experience with my father, Herminio ❤️ . Whenever he has a medical appointment, he opens the Apple Health app and shows the doctor the evolution of his heart rate, physical activity, sleep hours, and other recorded metrics. While watching this, I kept asking myself the same question: are we really making the most of all this information? Showing a chart during a medical appointment can be useful, but the data could provide much more value if it were automatically processed, summarized, and transformed into a structured health report. For this reason in this project, I use Gemini to transform previously calculated metrics into a clear and organized summary. The LLM does not analyze all the raw records or perform the main calculations. The pipeline processes the data, calculates the indicators, and generates the visualizations, while the model acts as a support layer for building the report narrative. The goal is not to create a medical application or replace professional judgment. Instead, the purpose is to build a prototype that shows how Apple Health exports, deterministic data processing, visualizations, and an LLM can be combined to generate automated reports. This project was developed using simulated data from three patients, so the complete pipeline can be reproduced without using real clinical information. ✨ Why Gemini? This project uses an LLM to transform previously processed metrics into a structured narrative that can be reviewed more easily by a healthcare professional. I chose Gemini for practical reasons: 〰️ I was already famil

Hey any one experience overall score 2.66 and then Meta score 3 in some previous cycle ?? Or meta reviewer just rounded off 2.66 to 2.5?? Any Meta Reviewer here?? because there are some uninterested reviewers doing AI generated reviews and giving noisy scores. For them overall score gets lowered. submitted by /u/Historical_Pause247 [link] [留言]

As someone who studied stats undergrad and industrial engineering operations research grad, and who thinks about the practical business of ML components in software.... I get lost and a bit hopeless when I think about how to make useful software out of ML models in a reasonable amount of time, and in the current business environment. And when I look at the businesses where I have worked that have mountains of middle management running tiny bits of the ML model lifecycle (think feature extraction, data ingestion and integration, training infra, hosting infra, more hosting infra, applied science)... that only makes my head hurt even more. How do you go about making practical software out of ML components? Edit: I should mention that I mean from scratch ML components, not just a call to a third party hosted tool. submitted by /u/ConstructionBoth6461 [link] [留言]

https://mdooai.com AI 모델을 다루다 보면 코드는 돌아가는데 왜 성능이 안 나오는지 이해하지 못하는 순간이 옵니다. 그 답은 대부분 수학에 있습니다. 실무 AI 개발자로 성장하기 위해 반드시 잡아야 할 최소한의 수학 개념과, 그것을 어떻게 공부해야 하는지를 구체적으로 살펴보겠습니다. 코딩만으로는 해결할 수 없는 AI 모델 성능의 열쇠 많은 주니어 개발자들이 비슷한 경험을 합니다. PyTorch나 TensorFlow로 튜토리얼 코드를 복사하고, 학습도 돌리고, 결과도 나옵니다. 그런데 모델이 왜 이렇게 예측하는지, 왜 학습이 멈추는지, 어떻게 하면 성능이 올라가는지는 설명할 수가 없습니다. 이 간극의 정체가 바로 수학입니다. 가령 모델이 과적합(overfitting)될 때 L2 정규화를 쓰라는 조언을 듣습니다. 코드 한 줄로 해결되지만, 그게 왜 작동하는지는 가중치 벡터의 크기를 제한한다는 선형대수와 확률론적 추론이 얽혀 있습니다. 이 원리를 이해하는 개발자와 모르는 개발자가 새로운 문제에서 만들어내는 솔루션의 질은 다를 수밖에 없습니다. 다행인 건, AI 개발에서 필요한 수학은 대학원 수준의 수리해석학이 아닙니다. 핵심 개념 몇 가지를 실용적 도구로 이해하는 것으로 충분합니다. 선형대수와 확률통계, 어떤 개념부터 공부해야 할까? 선형대수와 확률통계는 AI 수학의 두 축입니다. 그런데 이 두 분야 전체를 공부하려 들면 끝이 없습니다. 개발자 관점에서 실제로 반복해서 등장하는 개념만 추려내면 다음과 같습니다. 선형대수에서 우선해야 할 개념 벡터와 행렬의 연산 : 데이터는 사실상 전부 벡터와 행렬로 표현됩니다. 이미지는 픽셀값 행렬이고, 텍스트는 임베딩 벡터입니다. 행렬 곱(matrix multiplication)이 신경망의 순전파(forward pass) 그 자체입니다. 내적(dot product)과 유사도 : 추천 시스템, 어텐션 메커니즘(Transformer의 핵심)이 내적 연산 위에 서 있습니다. 고유값(eigenvalue)과 고유벡터(eigenvector) : PCA(주성분 분석)처럼 차원을 줄이는 기법을 이해하려면 반드시 필요합니다. 행렬 분해(SVD 등) : 추천 시스템과 자연어 처리의 기반 기술에 등장합니다. 확률통계에서 우선해야 할 개념 확률분포와 기댓값 : 모델의 출력이 확률인 이유, 소프트맥스(softmax)가 하는 일을 이해하는 기반입니다. 베이즈 정리 : 사전 지식을 데이터로 업데이트하는 논리 구조로, 생성 모델과 불확실성 추정에 직접 연결됩니다. 최대 우도 추정(MLE, Maximum Likelihood Estimation) : 모델 학습이 왜 손실 함수를 최소화하는 방향인지를 설명하는 원리입니다. 크로스 엔트로피 손실 : 분류 모델에서 가장 자주 쓰이는 손실 함수로, 확률론과 정보이론이 만나는 지점입니다. 분야 핵심 개념 AI 실무 연결 지점 선형대수 행렬 곱, 내적 신경망 순전파, 어텐션 선형대수 고유값·고유벡터 PCA, 차원 축소 선형대수 행렬 분해(SVD) 추천 시스템, NLP 확률통계 확률분포, 기댓값 소프트맥스, 분류 출력 확률통계 베이즈 정리 생성 모델, 불확실성 추정 확률통계 최대 우도 추정 손실 함수의 논리적 근거 확률통계 크로스 엔트로피 분류 모델 학습 활성화 함수와 역전파에서 미적분은 어떻게 작동하는가? 미적분은 신경망 학습의 핵심 메커니즘인 역전파(backpropagation)를 이해하는 데 필요합니다. 겁먹을 필요는 없습니다.

My Zero to Blockchain Engineer journey — Week 2 update Last week I announced I was teaching myself blockchain engineering from zero. This week I went deep into Cyfrin Updraft — and I have to be honest, it changed how I think about learning Web3. Here's everything I covered, what surprised me, and why I think this platform is the best free resource for anyone serious about becoming a blockchain developer. What I covered this week I'm currently 45% through the Blockchain Basics course on Cyfrin Updraft. Here's exactly what the lessons covered: Section 1 — What Is A Blockchain? This section answered the question properly — not in a surface-level way, but by starting with the problem blockchain solves. The lesson on centralized control hit differently. Think about it in a Nigerian context — banks freezing accounts, payment processors blocking transactions, elections where results can't be independently verified. These aren't hypothetical problems. They're things we live with. Blockchain's answer: a shared ledger where truth is verified by math, not by a middleman. That framing made everything click for me. Key lessons I completed: What Is A Blockchain — centralized problems vs decentralized solutions History Of Blockchain — from the double-spend problem to Bitcoin to Ethereum Benefits Of Blockchain — permissionless, immutable, credibly neutral Use Cases — DeFi, cross-border payments, DAOs, digital ownership Many Many Chains — L1s, L2s, Mainnets vs Testnets The Oracle Problem — why smart contracts can't access real-world data alone The Purpose Of Smart Contracts — math-based promises vs trust-based agreements What Is The EVM — Ethereum's computation engine explained simply Benefits Of Smart Contracts — decentralization, immutability, transparency Section 2 — Sending Transactions This is where things got hands-on — and where Cyfrin pulled ahead of every other platform I've tried. Key lessons: What Is A Wallet — your public address as a digital mailbox Setting Up A Wallet

Introduction Linux is the backbone of modern infrastructure. From cloud servers and firewalls to SIEM platforms and security tools, Linux runs silently behind most enterprise environments. For a Security Operations Center (SOC) analyst, understanding Linux is not optional — it is a core skill. One of the most critical security mechanisms in Linux is its file permission and ownership model. Attackers abuse permissions to execute malware, hide persistence, escalate privileges, and erase evidence. SOC analysts rely on permission analysis to detect anomalies, investigate incidents, and build accurate timelines. Become a Medium member This article covers Linux File Permissions and Ownership in deep detail from a SOC analyst’s perspective. It is designed to take you from absolute beginner to security-aware professional, with real-world examples, attack scenarios, and investigation insights. Why Linux File Permissions Matter in SOC In SOC operations, analysts constantly deal with: Authentication logs System logs Application logs Scripts and binaries Configuration files Evidence files during incident response Every one of these objects is protected by Linux permissions. From a SOC perspective: Incorrect permissions = security risk Permission changes = potential indicator of compromise Executable permissions = possible malware Ownership changes = possible log tampering Understanding permissions allows SOC analysts to: Detect unauthorized access Identify privilege escalation Spot malware execution Preserve forensic evidence Reconstruct attacker activity Understanding Linux File Permission Basics Linux follows a Discretionary Access Control (DAC) model. This means: The owner of a file controls who can access it Permissions define what actions are allowed Every file and directory in Linux has: A type Permissions An owner (user) A group These attributes decide: Who can read the file Who can modify it Who can execute it Viewing Permissions Using ls -l The most common command to i

I'm a Computer Science student about to start my 4th semester this September in Pakistan. My long-term goals are: - Maintain a high GPA because I want to pursue a fully funded Master's abroad. - Eventually work at a top tech company (FAANG or similar). - Become a genuinely good software engineer rather than just someone who can build projects. A bit about me: I actually enjoy programming. I like logic, problem-solving, debugging, and understanding how things work under the hood. My initial plan for the rest of this year (August–December) was to focus on: - Java - Spring Boot - Backend development - LeetCode and DSA - SQL - System Design (starting with the basics) - Building projects and putting them on GitHub However, my brother (he's also studying CS) has a very different opinion. He's heavily into AI, automations, AI agents, and vibe coding. He told me that spending so much time learning to code deeply is becoming less valuable because AI can already generate entire applications. He even mentioned one of his friends vibe-coded a complex website with AI that was supposedly extremely secure and feature-rich. His argument is that I should focus more on AI workflows and automation instead of traditional software engineering. My opinion is a little different. I feel like AI is an amazing tool, but someone still has to understand: - Architecture - System Design - Databases - Security - Scalability - Performance - Debugging - Clean code - Software engineering principles My thinking is that AI can generate code, but it can't replace understanding why the code works or making good engineering decisions. Now I'm questioning whether I'm becoming outdated before I've even started. So I'd really appreciate advice from people already working in the industry. Some questions I'd love honest answers to: If you were a 4th-semester CS student in 2026, what would you spend the next 4–6 months learning? Is investing heavily in Java, Spring Boot, DSA, and backend development still wort

Do you have 2 minutes? Let's find out together. Before you continue, one small note... This first article isn't about Java, SQL, or coding tutorials. Today is simply about introducing myself, sharing why I decided to start this blog, and telling you what you can expect from the journey ahead. The technical content begins from the next article. Now, let me introduce myself. Hello! I'm Kumudhasri. Today isn't my birthday. It's not New Year's Day. I didn't receive a job offer today. There isn't a special milestone to celebrate. In fact, today is just an ordinary Sunday. But then I asked myself, "Why wait for a special day when I can make today special by taking the first step?" I've never believed in waiting for the perfect time to start. There will always be another Monday, another month, or another excuse. For me, the right time isn't tomorrow. "The right time is right now." So, this is where my journey begins. I'm not someone with an extraordinary story, years of experience, impressive achievements, or exceptional skills. I'm simply a recent B.Tech graduate trying to become a Java Full Stack Developer. Like many people starting out, I'm learning one concept at a time, solving problems, building projects, making mistakes, and figuring things out as I go. Some days I'll make progress. Some days I'll feel stuck. And I'm okay with both. Why am I starting this blog? I'm not writing because I'm an expert. I'm writing because I'm a learner. This blog is my way of documenting everything I learn—not just the wins, but also the mistakes, the confusion, and the lessons that come from working through them. I want this blog to keep me accountable. I want a place where I can organize my thoughts, track my progress, and understand how far I've come. Most importantly, I want my future self to look back at these posts and remember what the beginning looked like. What can you expect from this blog? If you decide to follow this journey, here's what you'll find: SQL challenges and what

Stack Overflow's question volume has been falling since ChatGPT went public in November 2022 ( OpenAI ). The site that trained a generation of developers, and most of the AI tools those developers now use, is slowly emptying out. In October 2023, Stack Overflow laid off 28% of its staff ( Stack Overflow Blog ). CEO Prashanth Chandrasekar framed it as a restructuring toward profitability. Everyone in the industry understood the real cause. Traffic was down. The thing causing it was sitting in every developer's browser tab. This is not another "AI killed Stack Overflow" piece. That take is everywhere and it misses the actual problem. The interesting part is the feedback loop, and it points somewhere uncomfortable for the AI industry itself. The conventional story, and what it misses The popular version goes like this. Developers used to paste error messages into Google and land on a Stack Overflow thread. Now they paste the same error into ChatGPT, Claude, or Copilot and get a direct answer. Why click through to a forum, risk a condescending comment, and wait for a human when a model answers in two seconds? That part is true. It explains the traffic drop. It does not explain why the people building the AI should be worried. The seed corn problem Here is the part most coverage skips. Every large language model trained on internet text consumed a huge amount of Stack Overflow. The site's archive of voted, edited, human-reviewed answers is one of the highest-quality programming datasets in existence. It is the reason an AI can answer your Python error at all. Now run the loop forward. AI tools answer questions directly. Developers stop posting on Stack Overflow. The archive stops growing. The next round of models trains on a corpus that is increasingly old, increasingly stale, and missing everything that happened after 2022. When you train an AI on data generated by another AI, quality degrades. Researchers proved this formally. Shumailov and colleagues showed that model

Here's How One Engineer Is Walking on It I want to be upfront about what this post is and isn't. It isn't a list of five things you should do to stay relevant in the age of AI. I've read plenty of those, and I've tried to write one myself more than once. Every time, it came out sounding like advice I didn't actually have the standing to give. So this is the other kind of post — a description of how one person is muddling through, written precisely because I don't have the playbook. The ground moved under me The moment it became real for me was working with Claude Code on an internal project. I came in expecting to do what I've always done: tell the tool, in fine detail, how to accomplish a thing. Instead I found myself describing what I wanted and why , and handing off the details. The shift was quiet, almost embarrassingly small in the moment, and yet it kept nagging at me afterward. I've lived through paradigm shifts before. Web 2.0. Mobile. Each one had its share of "I need to go do the cool new thing for clients." But those were fundamentally about learning a new tool. This one feels different to me. It isn't asking me to learn a new framework. It's asking me to re-evaluate my place in the market and what my job even is. I work as a consultant who helps clients understand and adopt emerging technology, which means I don't get to sit this out in some established niche. The ground is moving, and I'm standing on it. The part I can't resolve Here's the scariest thing, and I'd rather say it plainly than tuck it away: after nearly thirty years of building precise, complex systems, I don't know whether all that experience is an advantage or a trap. I'd love to tell you that three decades of deconstructing hard problems gives me a head start on structuring intent for an AI. Some days I believe that. Other days I wonder whether my deterministic instincts — the habits that made me good at this — are exactly the reflexes I now have to unlearn. I genuinely can't tell yet. B

By the end of this article, you'll know: what Kimi K3 actually is, the architecture, the scale, and what changed from the K2 family how to run it today, free in the browser, through the API, or wired into Claude Code, Cursor, Cline, and RooCode which exact model ID and settings unlock the full 1 million token context how K3 stacks up on price and benchmarks against DeepSeek V4, Qwen3.7 Max, GLM-5.2, and its own sibling K2.7 Code whether switching today makes sense, or whether you should wait Kimi K3 just dropped, and Moonshot means business Moonshot AI released Kimi K3 on July 16, 2026, timed just ahead of the World Artificial Intelligence Conference in Shanghai. The Beijing lab, backed by Alibaba, has spent the past 18 months watching DeepSeek erode its market position. K3 is the comeback attempt, and the early numbers back it up. The headline result: K3 debuted at number one on Arena.ai's Frontend Code Arena with a score of 1,679, ahead of Claude Fable 5 at 1,631 and GPT-5.6 Sol at 1,618. Its predecessor, K2.6, sat 18th on that same board. That's a 17 spot jump in one release, and it's independently measured, not a number Moonshot invented itself. This isn't Moonshot's first time in Western production stacks either. Cursor built its Composer 2 model starting from a Kimi K2.5 base. DoorDash's CTO has said the company routes lower level work to Kimi K2.6. Thinking Machines used K2.5 to help generate early post-training data for Inkling, its own model released just a day before K3. So when a new Kimi flagship lands, it lands somewhere developers already have skin in the game. For developers, the practical story matters more than the leaderboard. K3 is open weight, speaks the OpenAI SDK, and drops into tools you already use. It's also, for the first time in Kimi's history, priced like a frontier model instead of a budget one. That changes the calculus on when it's actually worth reaching for. What Kimi K3 actually is K3 is a sparse Mixture-of-Experts model with 2.8 tr

A video-to-prompt tool looks simple from the outside: upload a clip, wait a moment, and copy the result. The hard part is not generating text. It is preserving enough of the source video's structure that the prompt remains useful when another model interprets it. I learned this while working on a small video analysis workflow. Early versions produced fluent paragraphs, but they often dropped a camera move, merged two events, or placed dialogue in the wrong shot. The output sounded good and still failed as a production prompt. The fix was to stop treating the result as one block of prose. Start with an intermediate representation I now treat the prompt as the last stage of a compiler. The video is first converted into a structured record, and only then rendered for a specific video model. A minimal record might look like this: { "duration_seconds" : 12.4 , "shots" : [ { "start" : 0.0 , "end" : 3.8 , "subject" : "a cyclist waiting at a red light" , "action" : "looks over the left shoulder" , "camera" : { "shot_size" : "medium" , "movement" : "slow push-in" , "angle" : "eye level" }, "dialogue" : null } ] } This structure is deliberately boring. That is useful. A typed record makes missing data visible and gives you something concrete to validate before you ask a language model to write polished prose. Normalize the input first Video files arrive with different frame rates, codecs, orientations, and audio layouts. Links from social platforms add another layer of inconsistency. If every downstream stage has to understand every input format, failures become difficult to reproduce. The ingestion stage should produce a canonical package: a timestamped frame stream at a known sampling rate a normalized audio track basic metadata such as duration, aspect ratio, and frame rate a stable internal time base Keep the original timestamps. Rounding everything to whole seconds is tempting, but it causes trouble in short clips where several actions happen in quick succession. Detect

I set out to deploy a fine-tuned LLM fully offline, on a mid-range Android phone, answering medical questions in Yoruba, Hausa, Igbo, and Nigerian Pidgin. No internet connection required, because that's the reality for a lot of the people this was meant to help. The model worked. Getting there broke three times, in three completely different ways, and left me with one problem I still haven't solved. The setup I fine-tuned unsloth/Llama-3.2-3B-Instruct , Unsloth's 4-bit-optimized derivative of Meta's Llama 3.2 3B, in two stages: QLoRA supervised fine-tuning on a curated dataset of 3,917 medical question-answer pairs across the four languages, followed by direct preference optimization (DPO) to sharpen response quality. SFT converged to a loss of 1.099. DPO landed a reward margin of 18.40. Then I merged to 16-bit and tried to convert to GGUF, the format llama.cpp needs to run the model on-device. That's where things started breaking. Crash 1: the tokenizer that thought it was someone else First conversion attempt. Model loads. First inference call. Instant crash: terminating due to uncaught exception of type std::out_of_range: unordered_map::at: key not found Turns out the conversion had written tokenizer.ggml.model = "llama" into the GGUF file. That field tells the runtime which tokenizer code path to use, and "llama" routes to SentencePiece. Llama 3.2 doesn't use SentencePiece. It uses BPE. The runtime was trying to read BPE tokens through a SentencePiece parser, and predictably, it found nothing where it expected something. Fix: manually set the field to "gpt2" , which routes to the correct BPE path. Crash 2: the tokenizer that couldn't decide what it was Fixed crash 1, tried again. New failure, before the model even finished converting: TypeError: Llama 3 must be converted with BpeVocab followed, after the code's fallback path kicked in, by: ValueError: Cannot instantiate this tokenizer from a slow version This one took longer to trace. Unsloth's saved tokenizer_c

How machine learning supports aircraft maintenance using operational data. Key Takeaways Predictive maintenance estimates component health before failure. Data quality determines model performance. Explainable models support maintenance decisions. Human review remains part of every maintenance action. Model performance requires continuous validation. Introduction Aircraft produce large volumes of operational data. Machine learning converts this data into maintenance support inspection planning and fault detection. What Is Predictive Maintenance? Predictive maintenance estimates the condition of aircraft components using historical and real-time data. The goal is to identify early signs of degradation before a failure affects operations. Traditional maintenance often follows fixed inspection intervals. Data-driven maintenance adds condition-based recommendations using operational evidence. Data Sources Model quality depends on reliable data. Common sources include: Engine sensor readings Flight data recorder information Maintenance records Aircraft utilization history Environmental conditions Component replacement history Incomplete or inaccurate data reduces prediction accuracy. Machine Learning Workflow A typical workflow includes: Collect operational and maintenance data. Remove errors and missing values. Create features from sensor measurements. Train the prediction model. Validate performance using unseen data. Monitor prediction accuracy after deployment. Retrain the model as new data becomes available. Model Selection Different problems require different algorithms. Common choices include: Random Forest XGBoost LightGBM Support Vector Machine Long Short-Term Memory (LSTM) Transformer-based time-series models Model selection depends on the prediction task, dataset size, and operational requirements. Engineering Challenges Data Quality Sensor failures, missing records, and inconsistent maintenance logs reduce model reliability. Class Imbalance Aircraft failures
