Human Mobility Datasets Enriched With Contextual and Social Dimensions

On December 4, the Chicago Tribune filed a copyright infringement lawsuit against Perplexity AI in New York federal court, claiming the startup has unlawfully profited from the newspaper's content while developing its AI-driven search engine.

Recent research evaluates the robustness of Large Language Models (LLMs) in generating formal proofs from semantically similar paraphrased natural language statements. This study utilizes benchmarks like MiniF2F and Lean 4 version of ProofNet to assess semantic and compilation validity, revealing that LLMs can be sensitive to paraphrased inputs despite maintaining high semantic fidelity.

An enhanced benchmark for evaluating linguistic acceptability in Danish has been introduced, focusing on common errors in written Danish. This benchmark includes fourteen corruption functions that systematically introduce errors into correct sentences, allowing for a more rigorous assessment of linguistic acceptability in Large Language Models (LLMs).

SignRoundV2 has been introduced as a post-training quantization framework aimed at improving the efficiency of deploying Large Language Models (LLMs) while minimizing performance degradation typically associated with low-bit quantization. This framework employs a fast sensitivity metric and a lightweight pre-tuning search to optimize layer-wise bit allocation and quantization scales, achieving competitive accuracy even at extremely low-bit levels.

The CALAMITA initiative, coordinated by the Italian Association for Computational Linguistics, aims to systematically evaluate Large Language Models (LLMs) in Italian through a collaborative benchmarking approach. This project involves over 80 contributors from various sectors to create a comprehensive benchmark of tasks that assess linguistic competence, commonsense reasoning, and other capabilities of LLMs.

A novel framework has been proposed to integrate Large Language Models (LLMs) with Knowledge Graphs (KGs), enhancing the reliability of LLM reasoning by linking each reasoning step to structured graph data. This approach aims to provide interpretable traces of reasoning that align with external knowledge, demonstrating significant improvements in performance on the GRBench benchmark.

A new Retrieval-Augmented Generation (RAG) system has been developed to enhance the querying of the UK National Institute for Health and Care Excellence (NICE) clinical guidelines using Large Language Models (LLMs). This system addresses the challenges posed by the extensive length of guidelines, providing users with accurate information in response to natural language queries. The system achieved a Mean Reciprocal Rank (MRR) of 0.814 and a Recall of 81% at the first chunk during evaluations on 7901 queries.

The introduction of the Mixed Memory-Augmented Generation (MMAG) framework aims to enhance the performance of Large Language Models (LLMs) by organizing memory into five layers: conversational, long-term user, episodic, sensory, and short-term working memory. This innovation addresses the limitations of LLMs in maintaining relevance and personalization during extended interactions.
