IBM Research: How Much Memory Does Your Agent Actually Need?

IBM Research introduces ALTK-Evolve-HMM, a method to evolve agent memory architectures using hidden Markov models. The approach automatically designs memory modules, improving performance on long-horizon tasks while reducing memory usage. The work is detailed in a Hugging Face blog post.

Hugging Face Reproduces 2,200 ICML Papers, Shares Lessons

Hugging Face published a blog post detailing an effort to reproduce 2,200 papers from ICML, sharing findings from the large-scale reproduction project. The post outlines what the team learned in attempting to verify and replicate results across this broad set of accepted machine learning papers, though specific quantitative findings were not detailed in the available excerpt.

New Research: LLM Judges Unstable, RAG Privacy, and More

New arXiv papers cover LLM judge instability (Wiggle Framework), privacy-preserving RAG (SEAG), multi-agent pricing, transformer expressiveness, constraint saturation, Dual-Flow Transformers, governed memory, and edge scheduling. Findings: judges flip verdicts 25-91% under pressure; SEAG hides sensitive entities with >74% accuracy; instruction following collapses beyond 5-6 constraints.

Google's AMIE AI Shows Real-Time Clinical Video Consultation Skills

Google's research medical AI system, AMIE, demonstrated real-time clinical video consultation capabilities in a first-of-its-kind study. The system was tested in simulated settings, showing potential for AI-assisted telehealth.

Microsoft Introduces CARE-X for Clinically Useful Radiology VLMs

Microsoft Research introduced CARE-X, a framework for radiology vision-language models (VLMs) that combines auxiliary supervision, reward-aligned learning, and tool-augmented measurement to improve chest X-ray interpretation. It aims to move beyond report generation toward flexible reasoning and calibrated predictions.
