We spent the last months consolidating seven separate sequence classifiers into one multi-head model, our apex model, so to speak, and since the weights are now public, I wanted to share what worked and what surprised us. Setup: a shared mmBERT-small encoder with seven task heads, binary injection (BCE), document class (7-way), tool type (14-way), tool operation (6-way), tool data-flow tags (3× BCE, multi-label), intent routing (5-way), and threat type (7-way). The part that needed care: our training rows only carry labels for a subset of tasks, so absent tasks are masked out of the loss entirely. We ended up writing a self-test that asserts absent-task gradients are exactly zero, which caught two subtle bugs, and I'd recommend it to anyone doing similar masking. About 5k synthetic/real multi-task rows help the heads co-train; the test sets stay 100 % real data. Held-out results per head: injection F1 0.962, documents 0.980, tool type 0.957, tool operation 0.945, tool tags 0.958, routing 0.916, threat 0.952. Quantization: both the unified model and the dedicated single-task variants ship quantized -edge builds (ONNX INT8 + INT4 embeddings, from 96 MB) with measured parity benchmarks in the repos, the worst head loses 0.012 against FP32. Was it worth it vs. seven dedicated models? We released both variants, so you can judge for yourself, the dedicated models score marginally higher on most tasks, but the unified one does one encoder pass instead of up to seven. Our weak spot: routing, at 0.916. The intent classes overlap semantically ("write code that analyzes my data" is that code or analytics?), and I suspect the ambiguity is genuinely in the data. If you have ideas beyond relabeling, let me know :) Weights and per-head metrics: https://huggingface.co/patronus-studio submitted by /u/PatronusProtect [link] [留言]

Hey, I would like to show you my project, but it's difficult because it only works with a registration, so I explain the concept to you. The Idea: Everyone who registers has to do an onboarding and answer meaningful questions that help you to find a right match. The matching happens by the system. Once you're done with the onboarding, you enter the pool. When a match is found, you go into a 1on1 14 question-set with that person. All answers are revealed immediately. At the end both decide if the

Less than a week before Meta's lawyers were set to return to a Los Angeles courtroom, the plaintiff accusing the platform of inflicting harm dropped the case. Brought by 15-year-old Florida plaintiff going by initials R.K.C., the case was set to be the second in a set of bellwether trials meant to test legal arguments […]

Hello. I really liked stackoverflow >5 years ago. There were many people asking about easy-to-medium problems to be solved, and it was a great way for me to learn C/C++/Bash/awk/sed/cmake/Linux/whatever by solving real-life(!) mediocre problems and also helping people in the process and also being criticized and corrected at the same time, from which I learned triple as much. Now stackoverflow is dead. My almost 150k reputation means nothing. Finally they added a "advice" type of questions which is way way too late. Now I lurk over reddit for typic-specific type of questions, but reddit is more a social network then help-me-with-programming-problem site, and the "help me" part is anyway so easy to solve with an AI. It was great back then - the feeling of learning something new and at the same actually helping and actually feeling like an expert in something. I learned the C programming standard by heart by answering really niche questions about C program behaviors. This was really fun for me. I enjoyed the specificity of stackoverflow - the idea of being "exact", answering only the question asked. There are just no questions nowadays on stackoverflow. There is a void now. And AI. There are topic-specific Discord chats, as a modern replacement of IRC, but I always assumed they are used by developers, not for noobs. I know the times without AI will never come again, but the internet, the thing connecting people across the whole globe, just feels more empty, more robotic and like an advertisement nowadays. submitted by /u/kolorcuk [link] [留言]
