Waypoint: Analytically Modeling GEMM for CPUs

The paper introduces Waypoint, an analytical model that automatically determines the optimal tile size for General Matrix Multiplication (GEMM) on CPUs. Waypoint predicts performance by accounting for memory hierarchy, instruction-level parallelism, and multi-threading, and uses these estimates to search for the tile size that maximizes throughput. The authors also present OPAM, a GEMM library that employs Waypoint to match state‑of‑the‑art performance and accelerate large language model inference on CPUs with 1.36–1.98× speedups.

Single-Cycle Battery Remaining Useful Life Prediction with Compressed Continuous Wavelet Features and Deep Neural Networks

The paper presents a method for predicting the remaining useful life of lithium‑ion batteries using only the first few charge‑discharge cycles. It transforms voltage, current, and capacity data into time‑frequency representations via continuous wavelet transform, compresses the resulting scalograms to reduce redundancy, and feeds them into deep neural networks. Experiments on eight benchmark datasets show the approach outperforms previous methods across diverse chemistries and cycling protocols, and visual explanations confirm the model focuses on meaningful time‑frequency regions.

SRA: Selective Residual Adaptation for LLM Reasoning Enhancement

Selective Residual Adaptation (SRA) is a plug‑in framework that improves multi‑step reasoning in distilled large language models by correcting sparse distribution divergences between teacher and student along reasoning paths. It uses a Discrepancy Gate to spot divergence points and a Candidate Residual Adapter to calibrate top‑K logits, thereby avoiding changes to the student backbone or runtime teacher computation. Experiments on Qwen3 models from 0.6B to 4B show that SRA raises average Pass@16 by up to 4.37 percentage points while maintaining general capabilities.

Entity-Aware Evaluation of OCR Systems for Historical Document Transcription

The paper introduces an entity‑aware evaluation framework for OCR systems applied to historical documents, focusing on how well names, dates, and identifiers are preserved. Using a benchmark of 175 Berrutti Archive documents and 5,209 manually annotated entity mentions, the authors compare sequence‑recognition OCR, OCR‑specialized vision‑language models, and general‑purpose vision‑language models. Their results show that OCR rankings vary with the evaluation criterion: Qwen 3.6 achieves the highest entity coverage, while some systems recover many entities when small character‑level errors are tolerated, indicating that aggregate transcription metrics alone do not capture meaningful information preservation.

UMAS: System-Level Uncertainty Quantification for Multi-Agent LLM Systems

UMAS is a parameter‑free, cost‑neutral framework for system‑level uncertainty quantification in multi‑agent large language model systems. It estimates the credibility of inter‑agent influence using each generation’s intrinsic confidence, modulates uncertainty updates at each node, and aggregates these into a system‑level estimate. Evaluations on Debate and DyLAN show UMAS outperforms state‑of‑the‑art baselines by an average of 10.54 AUROC points and improves hallucination detection and answer selection, boosting MAS accuracy by up to 12.6 points on specific tasks.
