ATLAS: Unified Agentic and Latent Visual Reasoning via Functional Tokens
ATLAS proposes a framework where a single discrete 'functional token' serves dual roles as both an agentic operation trigger and a latent visual reasoning unit in multimodal models. This design avoids the computational cost of generating intermediate images while sidestepping the context-switching latency of external tool calls and the generalization limitations of pure latent methods. The framework is compatible with standard SFT and RL training pipelines without architectural changes, and introduces Latent-Anchored GRPO (LA-GRPO) to stabilize reinforcement learning when functional tokens are sparse. Experiments show strong performance on visual reasoning benchmarks with maintained interpretability.
ATLAS: Active learning framework for automated discovery of interpretable behavioral models in cognitive science
ATLAS (Active Theory Learning for Automated Science) is a new active learning framework that iterates between generating mechanistic hypotheses as sparse neural network ensembles and designing maximally informative experiments to distinguish between them. The system is tested on recovering reinforcement learning agents from behavioral data in bandit tasks, achieving 5-10x sample efficiency improvements over random experimentation and matching expert-designed experiments from the literature. The work targets automated scientific discovery in cognitive science, with potential generalization to other domains requiring mechanistic modeling.
danielmiessler/Personal_AI_Infrastructure: agentic AI infrastructure framework in TypeScript
Daniel Miessler's Personal_AI_Infrastructure is a TypeScript project on GitHub framed as agentic AI infrastructure for augmenting human capabilities, currently trending with ~14,925 stars and 63 new stars today. The repository appears to be a personal AI agent harness or orchestration layer. Limited detail is available from the trending listing alone, but the star count indicates meaningful community traction.
Atlas H&E-TME: AI system matches expert pathologist accuracy for scalable tumor microenvironment profiling
Researchers present Atlas H&E-TME, an AI system built on the Atlas family of pathology foundation models that generates over 4,500 quantitative readouts per whole-slide H&E image at cell-level resolution across multiple cancer types. The system is validated using a novel dual framework: an IHC-informed multi-pathologist consensus protocol for depth, and benchmarking against 200,000+ annotations across 1,500+ cases from 25+ sources spanning eight cancer types. Atlas H&E-TME matches or exceeds pathologist H&E-only performance, demonstrating that standard histopathology slides can serve as a scalable quantitative window into the tumor microenvironment. The work advances computational pathology by enabling tissue-based biomarker discovery without requiring specialized staining modalities.
Multi-source cybersecurity log dataset with ATT&CK labels and SLM fine-tuning evaluation
Researchers introduce a new multi-source cybersecurity log dataset of 870 sessions (~2.3M events) capturing system, network, and browser activity on Windows endpoints, with per-entry MITRE ATT&CK technique labels across 12 tactics and 53 techniques. The dataset addresses gaps in existing public datasets (CICIDS, UNSW-NB15, ATLAS) that lack combined multi-source coverage with fine-grained ATT&CK labeling. Three small language models (Qwen2.5-1.5B, Llama-3.2-3B, Phi-4-Mini) were fine-tuned with LoRA on the dataset, achieving chunk classification accuracy of 90–97% versus ~8% for base variants, though ATT&CK technique identification remained harder at 42% exact-match accuracy.
