Multi-hop retrieval boosts hybrid sequence models' expressive power
A new arXiv paper proposes adding multi-hop retrieval to hybrid language models to improve their expressive power while keeping efficiency.
Hybrid model forecasts tropical cloud forest phenology under climate change
A new data-driven approach combining dynamical systems and machine learning could improve forecasts of ecosystem responses in hyper-diverse tropical cloud forests.
Coarse-Graining Reveals Fewer Effective Variables in AlphaEarth Embeddings
A new arXiv study suggests that AlphaEarth's 64-dimensional land embeddings may reduce to far fewer effective variables at coarser spatial resolutions.
Evidence-Guided Step-Level Rewards for Search Agents
A new reinforcement learning method, EG-GRPO, targets a key limitation in training LLM-based search agents by assigning credit at the step level using evidence.
Ridge-tracking sampling targets mixed response groups for web RL
A new arXiv paper proposes a sampling method that seeks out mixed-answer groups, where group relative policy optimization can actually learn.
Chess Transformer Follows Natural-Language Style Prompts
A 210M-parameter chess model generates moves from free-text style descriptions, bridging language and gameplay.
Fractional Hermite polynomials offer new basis for Kolmogorov-Arnold networks
A new arXiv paper proposes replacing Chebyshev polynomials with fractional Hermite polynomials in Kolmogorov-Arnold networks to avoid the need for input squashing.
Data mining needs a new vision for self-rewriting AI systems
A new arXiv paper argues that AI-native infrastructure, where agents modify their own data and models, breaks the core assumption behind classical data mining.
Age-Tuned Networks Simulate Infant Sensory Development
A new arXiv preprint proposes unifying measurements of sight, hearing, and touch in infants to build age-tuned simulations of early sensory experience.
EasyResearch Brings Honest Evaluation to Regression and Forecasting
A new arXiv paper describes EasyResearch, a tool that extends default-correct evaluation to numeric prediction, forecasting, and signal classification for non-programming researchers.
Probe Prior Fixes Zero-Variance Blind Spot in Group RL Post-Training
A proposed probe prior restores learning signal in group relative policy optimization when a binary verifier gives identical rewards to every response in a group.
Tracking Skill Lifecycles in Agentic Reinforcement Learning
A new arXiv paper proposes managing skill libraries in agentic RL by tracking how individual skills evolve as the policy changes.
Hidden Look-Ahead Bias in Electricity Market Weather Data
A new arXiv paper warns that commercial weather archives can introduce point-in-time leakage into electricity price models.
When Two Correct Models Fail Together in On-Policy Distillation
A new paper identifies a failure mode where teacher takeover in on-policy distillation yields wrong answers despite both models being correct individually, and proposes a contextual digest to fix it.
Java LLM Integration: A Reference Implementation for Consistent Error Handling
A new arXiv paper proposes a reference implementation and benchmark to standardize how Java frameworks handle failing LLM providers.
Multi-Site Deep Learning for Wind Power Forecasts in Great Britain
A new arXiv study applies multi-site deep neural networks to improve day-ahead wind-power forecasting for Great Britain's grid.
New Approach to Anomaly Detection in 5G and Open RAN Telemetry
A proposed method targets deployment bottlenecks in 5G/Open RAN observability by addressing heterogeneous KPIs, class imbalance, and alert budgets.
