SymLoc: Symbolic Localization of Hallucination across HaluEval and TruthfulQA

The COMPASS (Context-Modulated PID Attention Steering System) is introduced as a framework designed to mitigate hallucinations in large language models (LLMs). It incorporates a feedback loop within the decoding process, utilizing the Context Reliance Score (CRS) to assess how attention heads utilize contextual evidence. This system aims to ensure factual consistency in generated outputs without the need for retraining or multiple decoding passes.

HalluClean is a new framework designed to detect and correct hallucinations in large language models (LLMs). This task-agnostic approach enhances the reliability of LLM-generated text by decomposing the process into planning, execution, and revision stages. HalluClean utilizes minimal task-routing prompts for zero-shot generalization across various domains, significantly improving factual consistency in outputs.

ProRAC (Progression-based Reasoning about Actions and Change) is a neuro-symbolic framework that utilizes large language models (LLMs) to address reasoning about actions and changes (RAC) problems. The framework extracts essential elements from RAC problems, executes actions progressively to determine the final state, and evaluates queries against this state. Evaluations on various RAC benchmarks indicate that ProRAC demonstrates strong performance across diverse tasks and domains.

Large language models (LLMs) have shown impressive capabilities across various tasks, but their extensive size complicates real-world applications. Traditional pruning methods, like Wanda, require significant manual effort and expert knowledge, leading to high costs. This study introduces AutoPrune, a self-pruning method that allows LLMs to autonomously design optimal pruning algorithms, addressing the challenges of expert dependency and performance degradation due to uniform sparsity.

HSKBenchmark introduces a novel benchmark for modeling and assessing Chinese second language acquisition (SLA) using large language models (LLMs). This benchmark addresses the challenges of traditional language acquisition experiments, which are often impractical and ethically complex. HSKBenchmark encompasses HSK levels 3 to 6, featuring authentic textbooks and a comprehensive evaluation system, thereby enhancing the interpretability and scalability of LLMs in SLA.

Large Language Models (LLMs) have shown exceptional ability in text generation but often produce factually incorrect statements, known as 'hallucinations'. This study investigates hallucinations in conversational data across three low-resource languages: Hindi, Farsi, and Mandarin. The analysis of various LLMs, including GPT-3.5 and GPT-4o, reveals that while Mandarin has few hallucinated responses, Hindi and Farsi exhibit significantly higher rates of inaccuracies.

MedBench v4 introduces a comprehensive benchmarking framework for evaluating Chinese medical language models, multimodal models, and intelligent agents. This cloud-based infrastructure features over 700,000 expert-curated tasks across various medical specialties. The evaluation process includes multi-stage refinement and clinician reviews, with results indicating that while base LLMs score an average of 54.1/100, safety and ethics ratings remain low at 18.4/100.

Instruction tuning is a crucial method for aligning large language models (LLMs) with human intentions and safety requirements. This survey outlines the entire process, including data collection methods, fine-tuning strategies, and evaluation protocols. It categorizes data construction into expert annotation, distillation from larger models, and self-improvement mechanisms, each with unique trade-offs. The study also addresses challenges in evaluating model performance across multilingual and multimodal contexts.
