FlowReconBench: Sparse-Sensor Flow Field Reconstruction — Are Learned Models or Classical Methods Stronger?
FlowReconBench benchmark evaluates ten learned and five classical methods for sparse-sensor flow reconstruction. Classical methods lead with low-order, dense sensing; learned methods win with sparse sensing and low observability. Calibration and cost metrics yield different rankings.
Measuring Risk, Not Harm: A New Framework for Detecting Psychological Harm Risk Factors in LLM Conversations
Researchers propose "measuring risk, not harm": operationalizing LLM psychological harm risk as eight observable AI behaviors, building a synthetic multi-label corpus of 47K+ responses, and comparing embedding classifiers, LLM judging, and a cascade achieving F1 0.79 with 97.1% fewer judge calls.
Reinforcement Learning Unlocks Multi-Task Self-Evolution for Generalist Robot Policies
New research shows reinforcement learning enables multi-task self-improvement of generalist robot policies during deployment, with value-based RL and training task distribution as key factors, even generalizing to untrained tasks.
Where Is Mbed TLS Maintenance Heading? Community Discussion Draws Attention
Hacker News discusses the future maintenance of Mbed TLS. This article analyzes the potential impact of changes to this lightweight TLS library's maintenance arrangements on embedded and IoT projects, and offers advice for dependents on tracking and response.
Why Do Faithfulness Evaluation Criteria Disagree? A New Framework Offers a Navigation Path
The paper proposes a faithfulness functional framework that locates disagreement among faithfulness evaluation criteria in three dimensions—claims, comparisons, and aggregation—and uses adverse action notices to show how institutional context narrows operationalization choices, offering auditors a path to navigate conflicting evaluations.
Visual Token Routing: Letting Computer-Use Agents Process Only Key Visual Information
Visual Token Routing (VTR) jointly trains a lightweight spatiotemporal router so computer-use agents keep only essential visual tokens. With 2000 training steps, it matches full-resolution models on OSWorld, reduces visual tokens 2.5-5.8x, cuts inference cost 3.3x, and speeds up prefill 2.9x.
AMM: Budget-Aware Optimizer Routing via Online Probes
AMM uses online probes to measure curvature, separability, basins, and other terrain features, dynamically routing quasi-Newton, trust-region, coordinate, multi-start, and evolutionary strategy engines under a known budget. It holds the highest objective share in 382 of 600 held-out bbob cells, loses its lead on rotationally separable functions, and has lower anytime area than IPOP-CMA-ES on MA-BBOB.
Predicting Grain Growth with Time Series: Thermal-Conditioned Model Breaks Through Non-Isothermal Scenarios
A new study proposes a thermal-conditioned time-series prediction framework that encodes grain size distributions with a CNN, embeds thermal information via an MLP, and predicts evolution with an RNN, achieving second-level grain growth trajectory prediction under non-isothermal conditions with k-fold cross-validation R² above 0.99.
Go Releases a Brand-New JSON API: The Changes Brought by jsonv2
Go's official blog releases a new JSON API (jsonv2), sparking heated discussion on Hacker News. This article covers the new API's design philosophy, performance and compatibility trade-offs, community reaction, and impact on developers.
Google Introduces Agile Deliberation Framework to Tackle Subjective Image Classification
Google Research releases the Agile Deliberation human-AI framework, letting users define subjective visual concepts via borderline images; it lifts Gemini classifier F1 by 10.5 points over zero-shot in 18 sessions—ideal for gray-area image classification like content moderation and design review.
