Enforcing Batch Invariance in Agentic Kernel Generation
This study identifies that dynamic batching in LLM serving can alter numerical outputs for identical requests when kernels lack batch invariance (BI), a property overlooked by existing kernel-generation agents. The proposed tool combines contract-guided static dependency analysis with dynamic bitwise-consistency validation as a plug-in for general kernel agents, improving BI pass rates while retaining most of the baseline speedup.

Confidence Audit of Typed Decision Models: Promises vs. Reality
This study audits the reliability of confidence promises in typed decision models through large-scale experiments, revealing that point-estimate threshold selection often breaks promises while methods like Learn then Test keep them, and analyzes multilingual calibration, noise robustness, and drift scenarios.

TimeHAT: A Hybrid-Attention Pretraining Framework with Point-Patch Masking for Time Series
The paper proposes TimeHAT, a general-purpose time-series pretraining framework whose unified point-patch masking supervision covers both fine-grained fluctuations and broader temporal patterns, and whose hybrid attention encoder aims to mitigate rank degeneration; it is evaluated on classification, long-term forecasting, imputation, and anomaly detection.

Historically Anchored LLM Improves Public Opinion and Election Prediction Accuracy
This study introduces Matching-LLM, a weighted framework combining LLM-generated responses with historical human behavioral data to improve public opinion and election predictions; its novelty lies in calibrating LLM outputs with historical data and validating across multinational surveys and the 2024 U.S. election.

DocSkill: Learned Skill Orchestration for Multilingual Multi-Hop Document QA
The work presents DocSkill, an agentic framework whose learned skill-orchestration policy adaptively selects, revisits, or skips evidence-acquisition skills across multi-page, multilingual documents while tracking evolving evidence state; it also releases MMHop-DocBench, a 60K QA-pair benchmark spanning 10 languages and eight document domains with page- and element-level evidence annotations.

AC-JEPA: Anchored Cross-Modal Joint Embedding Predictive Architecture for Visual-to-Symbolic Translation
Introduces AC-JEPA, an SFT-compatible plug-in that predicts masked intermediate states in both cross-modal directions and uses continuous latent targets to tolerate local errors in paired data. On optical chemical structure recognition, it achieves 76.07% accuracy with clean training and 80.23% after pseudo-labeled self-training, outperforming SFT alone.

Predictive Validity of ICT's AMD Model on Nasdaq-100 Futures
This study provides the first systematic quantitative evaluation of ICT's Accumulation-Manipulation-Distribution (AMD) model on CME E-Mini Nasdaq-100 futures, operationalizing the model into a strict mechanical strategy and testing its signal's statistical properties. Its novelty lies in using real high-frequency data to reveal a structural mismatch between the model's timing assumptions and actual price delivery, and in finding that the signal carries directional information

Investor's Last Exam: Evaluating AI Agents on Equity Research Under a Frozen Information Set
This work introduces Investor's Last Exam (ILE), a benchmark that evaluates AI agents across the full equity-research process using a versioned, timestamp-governed financial database and an expert-led scoring framework under a strictly frozen information set. Its novelty lies in shifting the unit of evaluation from isolated capabilities to the evidence–assumption–judgment chain and in jointly measuring research quality, forecast accuracy, and simulated investment performance,

WeVisCut: A Single Agent for End-to-End Narration-to-Long-Form Video Editing
Existing agentic editors often rely on multi-stage workflows driven by general models, leaving the quality-cost trade-off of compact task-adapted policies unclear. WeVisCut connects tool execution with policy learning, using a single 9B policy for long-form video production and achieving performance comparable to Claude Opus 5 with far fewer generated tokens in a shared tool environment.
