machine learning Sep 17 Can an AI Scientist Start with a Dataset Instead of a Goal? What Happens When an AI Scientist Works Backward From Data? Every automated research system starts the same way: someone picks a question. That step, choosing what to investigate, is usually the one humans do before handing the re... machine learning Sep 17 Probabilistic Linear Explanations When a machine learning model denies someone a loan or flags a medical scan, the most natural question is "why?" Formal explainability has spent years trying to answer that question with mathematical rigor. The dominant approach f... machine learning Sep 17 Double descent is the principle of least action The double descent phenomenon is one of the most counterintuitive findings in modern machine learning. Train a model with a small number of parameters and test error falls as you add more, following the classical bias-variance cur... machine learning Sep 16 Knowledge as Orbit: Finite Collections as Phases of an Exactly Periodic Latent Generator Machine learning stores knowledge extensionally. Every item in a collection gets its own code, its own latent vector, its own row in a codebook. For X objects, you need X entries. The question this paper asks is whether a finite c... machine learning Sep 15 Show HN: Chess Cheater Detector A web tool called ChessCheaterDetector is offering players and tournament organizers a way to quantify how engine-like a chess game looks from a statistical perspective. The site at chesscheaterdetector.com takes a PGN file, runs... machine learning Sep 14 A Letter from a Machine Learning Engineer An anonymous email claiming to be from a machine learning engineer at a frontier AI lab has been published online, and its contents paint a picture of an industry running on hype rather than fundamentals. The author, writing from... machine learning Sep 14 Type Diversity Enables Transformers to Generalise Compositionally The compositional generalisation problem has haunted Transformer research for years. Train a seq2seq model on "John drinks coffee" and it learns to translate that just fine. But give it "John drinks coffee on a mat" when only "on... machine learning Sep 12 How SaaS startup guys get first 100 customers first, make fkn $500k ARR fast? This is a single question with no factual content, no technical details, and no discussion thread included. There is nothing to rewrite. machine learning Sep 11 NVIDIA Personal AI Router Distributes AI Tasks Across Local Compute NVIDIA released PAIR, Personal AI Router, in beta this week. The tool distributes AI inference requests across multiple machines on a local network, and it does so without requiring changes to the tools you already use. If you are... machine learning Sep 11 General Quantification of Covariate and Concept Shifts Distribution Shift Is a Broken Promise Every deployed model makes an implicit bet: that the data it sees at inference will look like the data it trained on. When that bet fails, performance degrades silently and sometimes catastro...
