SMART: A Surrogate Model for Predicting Application Runtime in Dragonfly Systems

Recent research indicates that large language models (LLMs) struggle to generate outputs that align with specified probability distributions. Experiments revealed that when asked to produce binary outputs with a target probability, LLMs consistently failed to meet these expectations, often defaulting to the most probable answer. This behavior undermines the probabilistic exploration necessary for scientific idea generation and selection, raising concerns about the effectiveness of current AI training methodologies.

The paper titled 'Beat the long tail: Distribution-Aware Speculative Decoding for RL Training' introduces a new framework called DAS, aimed at improving the efficiency of reinforcement learning (RL) rollouts for large language models (LLMs). The study identifies a bottleneck in the rollout phase, where long trajectories consume significant time. DAS employs an adaptive drafter and a length-aware speculation policy to optimize the rollout process without changing model outputs, enhancing the overall training efficiency.

Meta-SimGNN is a novel WiFi localization system that combines graph neural networks with meta-learning to enhance localization generalization and robustness. It addresses the limitations of existing deep learning-based localization methods, which primarily focus on environmental variations while neglecting the impact of device configuration changes. By introducing a fine-grained channel state information (CSI) graph construction scheme, Meta-SimGNN adapts to variations in the number of access points (APs) and improves usability in diverse scenarios.

DataSage is a novel multi-agent framework designed to enhance insight discovery in data analytics. It addresses limitations of existing data insight agents by incorporating external knowledge retrieval, a multi-role debating mechanism, and multi-path reasoning. These features aim to improve the depth of analysis and the accuracy of insights generated, thereby assisting organizations in making informed decisions in a data-driven environment.

Flaky tests, which unpredictably pass or fail, hinder developer productivity and delay software releases. FlakyGuard is introduced as a solution that leverages large language models (LLMs) to automatically repair these tests. Unlike previous methods like FlakyDoctor, FlakyGuard effectively addresses the context problem by structuring code as a graph and selectively exploring relevant contexts. Evaluation of FlakyGuard on real-world tests indicates a repair success rate of 47.6%, with 51.8% of fixes accepted by developers, marking a significant improvement over existing approaches.

The article presents a new framework called GMAT, which enhances Multiple Instance Learning (MIL) for whole slide image (WSI) classification. By integrating vision-language models (VLMs), GMAT aims to improve the generation of clinical descriptions that are more expressive and medically specific. This addresses limitations in existing methods that rely on large language models (LLMs) for generating descriptions, which often lack domain grounding and detailed medical specificity, thus improving alignment with visual features.

The research paper explores the challenge of false information and the effectiveness of large language models (LLMs) in verifying factual claims in English and Telugu. It presents a bilingual dataset and evaluates various approaches for classifying the veracity of claims. The study aims to enhance the efficiency of fact-checking processes, which are often labor-intensive and time-consuming.

Safety-aligned large language models (LLMs) are increasingly used in sensitive applications where fairness is crucial. Evaluating their fairness is complex, often relying on standard question-answer methods that misinterpret refusal responses as indicators of fairness. This paper introduces the concept of silenced biases, which are unfair preferences hidden within the models' latent space, masked by safety-alignment. Previous methods have limitations, prompting the need for new approaches to uncover these biases effectively.
