Many-Body Collective Fluctuations Generate Observable Contributions to Berry Curvature

This paper extends the quantum geometry framework — traditionally formulated via interband matrix elements — to incorporate Berry curvature contributions arising from many-body collective fluctuations, where propagators and response vertices are dynamically dressed by interactions with collective modes. The authors…

Sub-€40 Open-Source Wearable Achieves 0.77 F1 Four-Stage Sleep Classification Without Gel Electrodes

OSSMM is a fully open-source sleep research platform built from 3D-printed parts and COTS components for under €40, capturing EOG, putative EEG, movement, and pulse via a gel-free forehead headband with wireless connectivity. A 15-night single-subject proof-of-concept achieved a Macro F1 of 0.770 and accuracy of 0.776…

Kelpie: Zero-Query Adversarial Mimicry Attacks Expose Fundamental Weaknesses in ML-Based Binary Function Classifiers

Kelpie is a black-box, query-free adversarial framework that executes targeted mimicry attacks against ML-based binary function classifiers — a significantly stronger threat model than prior evasion work, which typically required iterative classifier queries. By applying functionality-preserving code transformations,…

RL Fine-Tuning Encodes Reusable Combinatorial Solvers into LLM Weights, Beating Repeated Sampling by 91x

Rather than treating combinatorial optimization as a repeated inference-time search problem, this paper demonstrates that GRPO-based RL fine-tuning of a code LLM (Qwen2.5-Coder-14B-Instruct) can internalize solver construction into model weights, producing a reusable algorithm generator. On Synergistic Dependency…

ML-Driven Quasar Catalog from DES DR2 Achieves High-Precision Classification and Photo-z Estimation at Cosmological Scales

A cross-match of DES DR2 photometry with SDSS DR16 spectroscopic labels yielded a training set of 168,738 point-like objects, enabling a KNN classifier to separate quasars from stellar contaminants at 0.99 precision and 0.77 recall using only four-band PSF magnitudes. Photometric redshifts were estimated via a hybrid…

The question is whether distillation plus a bit of search can get us past the frontier of the training corpus." [2] karpathy/podcast/dwarkesh-ep-127 (42:17) "The bitter lesson applies. Scale matters more than curation, but only once your curation floor is high enough to not poison the pretraining run." [3] karpathy/youtube/nn-zero-to-hero-8 (1:03:44) "I keep coming back to the idea that synthetic data is a compiler. You write the high-level intent and let the model lower it into tokens the next model can learn from." contradiction: lecun/tweet/2026-03-28 "Autoregressive synthetic data is a dead end. You cannot bootstrap past the distribution your base model already covers. Period." > write draft action to ~/Obsidian/inbox/absorb/synthetic-data.md
