As an ML researcher, how do you use AI tools in your daily work? Do you mostly use them to clean up grammar and wording, or also to rewrite, structure, or draft technical text? submitted by /u/Hope999991 [link] [留言]

TL;DR: Reliability techniques (methods that boost an LLM's correctness by spending extra inference, e.g., retries with feedback, ensembling, generator/critic refinement, verification passes, difficulty-aware routing) are scattered across the literature, each in its own paper-specific codebase. We unified 28 reliability techniques ( 21 communication-theoretic methods across 6 families plus 7 prior-method baselines : Self-Consistency, Self-Refine, CoVe, BoN, Weighted BoN, CISC, MoA), each measured against an uncoded single-pass baseline, under a single API, with 3 adaptive routers (SemKNN + two local ACM routers) sitting on top, then showed that routing the technique adaptively per prompt lets you slide along a quality/cost frontier. In our paper benchmark with one specific lineup, Nemotron + Devstral as the two generators and GLM-5.1 as the judge, the adaptive router delivered ~56% cost reduction at matched quality, or ~7% quality bump at matched cost, vs the best fixed method we compared against at that same lineup. One knob ( λ ) does the sliding. The qualitative pattern (adaptive beats fixed) should generalize, but absolute numbers are lineup-specific, and we haven't run the full sweep across other model combinations yet. Adoption is change one import : python - from openai import OpenAI + from agentcodec.openai import OpenAI Pass reliability="harq_ir" (or any of the 28 techniques) and existing client.chat.completions.create(...) calls keep their native OpenAI response shape. Same drop-in shims for Anthropic and Ollama. GitHub: https://github.com/intellerce/agentcodec Working paper: https://arxiv.org/abs/2605.09121 After spending a while researching reliability methods from papers, we kept hitting the same wall: every paper ships its own one-off codebase with its own prompt format, its own scoring rubric, its own model wrapper. Benchmarking "should we use self-refine or best-of-N here?" turned into a week of plumbing per comparison. The communication-theory framin

Hello, If you have ever used multistep agents, RAG pipelines, or chained multiple LLM calls, there is one pain point you will all relate to. When an agent gets stuck in an infinite loop, suddenly hallucinates on the third step, or is quietly burning through OpenAI API credits... tracing exactly where the problem originated is a real nightmare. Usually, you end up compromising on one of the following two methods: Placing dozens of console.log or print() statements all over your once-clean code. Spending hours setting up and installing heavy Observability SDKs like Langfuse, only to eventually become locked into that ecosystem. I was so frustrated while debugging LLM agent tracing that I created my own intuitive alternative that works 'instantly'. The key is simply replacing the baseURL. 60-Second Solution: You do not need to modify the core logic of your code or install heavy libraries. Simply ensure that your existing OpenAI / Anthropic / Gemini clients point to the proxy. https://preview.redd.it/dlgok064fa5h1.png?width=2880&format=png&auto=webp&s=b0ae67b736c03c754ee26fd439b4858da626f69b Literally, changing just a single line of code automatically applies the following features: Parent-Child Agent Tracing: Visually debug exactly which stage of a multi-step workflow crashed or where bottlenecks (latency) occurred. Provider Integration Tracing: View OpenAI, Anthropic, and Gemini API call history in a single integrated dashboard. Perfect for teams using multiple LLMs. Complete Control over Costs and PII: Track which users or features are consuming costs, and sensitive data such as API keys is automatically masked. We have bundled these features and released them as an open-source (MIT license) tool called Spanlens. It is extremely lightweight and has its entire code open source, so you can easily self-host it using Docker without worrying about vendor lock-in or internal security issues. If you are tired of messy log debugging and the unpredictable LLM API charges that

Hey Folks! 👋 Good Day... This blog is a summary of the concepts covered during the last two classes at my institute. One of the reasons I enjoy writing these blogs is that they serve as my personal knowledge journal. Whenever I need a quick refresher on a concept, I can simply revisit my blog instead of searching through notes or recordings. It helps me reinforce what I've learned while also documenting my learning journey. Over the past two days, we explored several important Java concepts, including constructors, the this keyword, inheritance, constructor chaining. In this blog, I'll share what I learned in the simplest way possible, using real-world analogies, practical examples, and the thought process that helped me understand these concepts more clearly. If you're a beginner learning Java, I hope this walkthrough makes these topics a little easier to grasp and a lot more memorable. What Is a Constructor? According to Oracle Java Documentation: A constructor is a special method that is used to initialize objects. The constructor is called when an object of a class is created. In simple terms: Imagine you order a new smartphone. Before the phone reaches your hands, the factory installs the operating system, configures the hardware, and prepares everything for use. A constructor does exactly the same thing for an object. Before you use an object, Java uses the constructor to prepare it. My First Confusing Example I wrote the following code: public class SuperMarket { String name = "python" ; int price ; public SuperMarket ( String name , int price ) { System . out . println ( "Are you constructor?" ); name = name ; price = price ; } public static void main ( String [] args ) { SuperMarket product1 = new SuperMarket ( "abc" , 20 ); System . out . println ( product1 . name ); } } I expected the output to be: abc But Java printed: python And honestly... I was completely confused. After all, I passed "abc" into the constructor. Why was Java ignoring it? The Hotel Roo

The Google paper on metacognition for hallucination reduction makes a distinction that is underappreciated in benchmarks. Calibration is not about being right more often. It is about matching confidence to correctness. A perfectly calibrated model can still be wrong twenty five percent of the time. It just does not pretend otherwise. In agent systems this distinction matters more than in chat. A conversational model giving a hedged answer is slightly annoying. An agent with tool access acting confidently on a wrong premise is dangerous. I have been trying this in a small verdent based coding setup by splitting the pipeline into a planning stage that produces a task graph, then running a verifier before any expensive tool gets invoked. The risk is the model trusts its own reasoning even when speculative. Grounding helps but it is not the same as calibration. One practical pattern: a planning stage produces a task graph, then a lightweight verifier checks whether the plan is consistent with available evidence. This catches about sixty percent of hallucinated tool calls in my setup before they execute. The downside is the utility tax. Extra verification adds latency. Dropping hallucination from twenty five to five percent costs about half the easy correct answers, mirroring the paper. My current compromise: let the planning layer flag low confidence tasks for human review, but auto execute high confidence ones. The reviewer only sees edge cases instead of drowning in every step. The awkward part is that most agent stacks still treat confidence as a log detail, not as a control surface. submitted by /u/Ill_Awareness6706 [link] [留言]

Excited to share some of my own work here :) KVarN is our new KV-Cache quantization method. In very brief, we combine Hadamard rotations with variance-normalization on both axes of the K and V matrices, then round to nearest. Simple, but works very well, especially for decode-heavy test-time-scaling settings (reasoning, code-gen, agentics). We get 3-4x compression at virtually no accuracy drop (mostly 0-1%) on tough benchmarks like AIME24 as well as a speed-up over fp16 baseline in vLLM (in contrast to other recent KV-Cache compression works). Behind it is an analysis of where quantization errors come from and have the biggest impact, especially in the error-accumulating decode setting: 1) fixing large errors is disproportionally useful (if you had a fixed MSE budget that you could ~fix, you should spend it on few big errors, rather than many small) 2) These big errors are mostly caused by bad token-scales (hence the normalization).

Hi, Niels here from the open-source team at Hugging Face. At paperswithcode.co I am trying to make it easier for people to learn about the newest techniques used across AI papers. One of the hottest terms in AI research that I've recently added is On-policy distillation , also abbreviated as OPD. It's the key post-training behind models like Qwen 3.6 and 3.7, GLM-5.1, and DeepSeek-V4. https://preview.redd.it/yegq2gfag95h1.png?width=3046&format=png&auto=webp&s=f68fdf3ca075f3c4e56051fdd0ebcf97be9bcbc9 On PapersWithCode, you can find the original paper that introduced it, learn more about the method itself, as well as all papers that cite or mention it. Sasha Rush (who used to be a colleague of mine at Hugging Face, now at Cursor) recently made an excellent whiteboard explanation of OPD with Dwarkesh. I've linked this video lecture in the method description on PwC's website, so more people can find it. I'll copy the excellent short description of the method from Dwarkesh here: "The basic idea is this: if the model made a mistake at some point in the rollout (for example, calling a tool that doesn't exist), we want to discourage this specific error, but we don't want to just learn from the final reward, because it's a very noisy signal spread out over the whole trajectory. So we have another model to read this trajectory and figure out where the error was made. It simply inserts some hint tokens into the part of the trajectory immediately above where the mistake occurred. Now, with these injected hint tokens, run a forward pass through the model. You're not having to regenerate a new rollout - aka no new decode required. The hint causes the model to assign lower probabilities to the error tokens. You then train the original model to match these new probabilities, teaching it to downweight that specific mistake." Let me know which other methods I should add!

Hello I am curious about the election criteria for ICML financial aid. If anyone have been granted financial aid would you mind sharing your profile. Somehow being a black woman ( 2 underrepresented groups) with one paper accepted at the main conference and two papers accepted at different workshops is not enough to get financial aid. Are they solely for oral papers perhaps ? Last year a colleague (white man) with one spotlight paper did not get it neither. Maybe you need to belong to all minority groups ( half black half Latina Native American woman lgbtq+ and so on so far and what have you) with at least 3 oral papers 💀💀 to get any sort of help? The selection process and criteria should have more transparency cause chances are people in those committees are just giving the money to their own student and postdocs. submitted by /u/DazzlingPin3965 [link] [留言]

I'm running into an issue with an ablation study for a paper I'm preparing. I trained a model. The model achieved my best result, and I saved the trained checkpoint ( .pth file). Now my supervisor wants me to perform an ablation study by removing components and how it impacts the accuracy. My concern is that if I retrain from scratch, the accuracies will not exactly match the original run due to randomness, different seeds, etc. is there any way i can do the ablation study without retraining? I'd appreciate hearing how others have handled this situation in publications or thesis work. please help me out submitted by /u/Plane_Stick8394 [link] [留言]

Initially, I developed this so I can easily switch between different Attention mechanisms for my Small Language Model (SLM) experiments and benchmarking. However, I also realized that these implementations can be applicable in Computer Vision, modernize Vision Encoders, RL, and others. I hope this helps researchers, students, or educators in general. I also included MiniMax M3's sparse attention. This can be integrated with Andrej Karpathy's autoresearch framework. For contributing: I encourage you to please open a PR. I would like to see and learn implementations of other attention mechanisms I haven't covered in this repo. Thank you!

The chatbot is tricking me!!! 💬📜⌛ When you text a chatbot, it doesn’t actually remember who you are or what you said two minutes ago. The exact millisecond it finishes typing a response, its brain completely wipes clean. To pull off the illusion of a continuous, flowing conversation, the web application secretly copy-pastes the entire past chat history, bundles it up, and blasts that whole massive block of text back into the processor every single time you hit send. Your "chat session" is an illusion maintained entirely by an ever-growing stateless prompt wrapper. You aren't interacting with a growing, adapting mind; you are repeatedly gas-lighting a brand-new entity into believing it has been talking to you for an hour. Wait, I am the one training it ??? 🚦🚸🚲 AI models are inherently blind to context; a computer doesn't instinctively know that a specific cluster of raw pixel values represents a real-world object. It requires billions of examples to be manually labeled by a human mind before the math can understand it. Every time you click on squares containing "traffic lights," "crosswalks," or "bicycles" to unlock a website, you are acting as an unpaid data annotator. You are manually labeling complex, messy real-world data points that feed directly into the computer vision systems of autonomous vehicles. The grand paradox of modern cyber security is that we force humans to act like mechanical data annotators to prove they are not computers, all so that computers can learn how to perfectly impersonate humans. The supercomputer is stupider than a toddler... 🍓👶🏻🖥️ We assume AI read letters and words the same way human eyes scan a page. It doesn't—it is entirely alphabet-blind. Before text hits the AI's brain, a parser chops strings of text into numerical blocks called "tokens." For example, the word "strawberry" isn't seen by the model as ten distinct letters; it is compressed into numerical IDs representing chunked pieces like "straw" and "berry". Because it never s

ok so the model's been up on HF now (apache 2.0, ~12B BF16, any-to-any multimodal). community has already shipped a pile of quants: - GGUF: unsloth, bartowski, ggml-org, lmstudio-community - MLX: mlx-community has 4bit / 8bit / bf16 / nvfp4 - official: google/gemma-4-12B-it (BF16) and the -assistant variant still trying to figure out which combo is actually worth downloading. the "12B runs on your laptop" hype is loud but i haven't seen many concrete numbers. if you've got it running, drop: - hardware (chip / RAM / GPU) - which quant + which repo (e.g. unsloth Q4_K_M, mlx-community 4bit, etc.) - runtime (llama.cpp / ollama / lm studio / mlx-lm / vllm / transformers …) - tokens/sec - context length you've actually used in practice - what you're using it for (chat / code / OCR / vision / agent …) - one thing it does well + one thing it falls apart on genuinely curious where the floor is — does it actually work on 16gb or only 32gb+? is mlx noticeably faster than gguf on apple silicon in 2026? anyone using the multimodal side seriously, or is it text-mostly in practice? submitted by /u/Individual_Soil4641 [link] [留言]

Hey everyone! Welcome back to my Google Summer of Code (GSoC) journey. In my last post, I shared the story of how I got into open source and was selected for GSoC with NumFOCUS to work on the Neural Network Builder API Refactor project for sbi (Simulation-Based Inference). Since the official announcement, the past three weeks have been dedicated to the Community Bonding Period . It is designed to help contributors get to know their mentors, understand the community culture, and familiarize themselves with the codebase and tools. Here is exactly what I did during these past three weeks to get ready for the main coding phase! The Kickoff Meeting We started the bonding period with a great kickoff call on Google Meet. It was a joint meeting that included the mentors for both of the selected sbi projects, the selected GSoC candidates. We were also joined by the mentee who successfully completed the GSoC project for sbi last year! Everyone introduced themselves, and it was incredibly inspiring to meet the team face-to-face (virtually!) and hear about everyone's backgrounds. Having a former GSoC student there was a huge bonus, as they shared some great insights into what to expect in the coming months. Setting Up the Machine A big part of getting started is making sure the development environment is properly configured. During our meetings, we discussed the machine setup in detail to ensure both candidates had everything required to run and test the sbi codebase locally without any hiccups. Embracing AI Coding Assistants One of the most interesting discussions we had was about using AI coding assistants. In the modern development world, tools like these are becoming standard, and our mentors actually encouraged us to use them! However, they emphasized using them carefully and strictly following project guidelines. To help us get the most out of these tools without compromising code quality, the mentors shared some excellent Claude code tutorials and provided us with resour

A lot of recent progress in ML appears to come from scaling existing architectures rather than introducing fundamentally new ones. At the same time, there’s increasing emphasis on dataset quality, curation, and synthetic data pipelines. In practice, I’m trying to understand how this tradeoff looks in real systems: How much effort is typically spent on data cleaning and filtering vs model design?? Whether dataset quality improvements still yield larger gains compared to architectural changes?? How synthetic data is affecting training stability and generalization in practice?? In many applied settings, it seems like data constraints become the limiting factor before architecture does, but I’m not sure if that’s broadly true across domains. submitted by /u/Electrical_Mine1912 [link] [留言]

I didn’t expect to care this much about language tools. I started messing around with two different projects, Linguaboard and Parley , mostly out of curiosity. What I got was a surprisingly clear look at two very different ways we interact with language as developers and builders. Linguaboard: translation as exploration, not just output Linguaboard isn’t trying to give you the translation. Instead, it feels more like it’s saying: “Here are several valid ways this could be expressed, pick what fits your intent.” That shift is subtle but important. Most translation tools optimize for a single “correct” answer. Linguaboard leans into ambiguity in a way that actually helps you understand nuance instead of hiding it. I found myself thinking less like: “What does this mean?” and more like: “How should this sound in context?” Parley: learning through interaction, not memorization Parley takes a completely different angle. Instead of treating language as something to decode, it treats it as something to use. You’re not just passively consuming translations, you’re engaging with patterns, context, and recall in a more active loop. What stood out to me is how quickly it shifts you out of “study mode” and into “usage mode.” It feels closer to building intuition than studying rules. The interesting contrast What I didn’t expect is how well these two complement each other: Linguaboard → helps you understand nuance and meaning Parley → helps you internalize and use language One is about interpretation, the other about retention through interaction. Put together, they highlight something a lot of dev tools miss: Language work isn’t one problem. It’s at least two: understanding, and using. Why this matters (especially for devs) If you’re building anything with multilingual UX, AI translation, or global audiences, you’ve probably hit this wall: Translation APIs give you “correct” text But correctness ≠ clarity, tone, or intent These tools made that gap feel very obvious to me. And o

I just finished my first year of undergrad, and I got my first first-author paper accepted to an ICML workshop! Super stoked, especially since I was lowk a crashout in high school I wanted to know if it is worth it for me to go? It's quite expensive, and I will be the only one in my lab in attendance, so I will be on my own. If I do attend, how would I best maximize this opportunity? I got an email saying main conference tickets would also be made available for accepted authors, so I would likely be able to attend that as well. What are the best ways to network, meet people, and make sure it's worth it? Also, I am applying for transfer for this next cycle, so any advice relevant to that is also appreciated. submitted by /u/YukiOnnaLake [link] [留言]
