ECG-aBcDe: Overcoming Model Dependence, Encoding ECG into a Universal Language for Any LLM

arXiv:2509.12625v1 Announce Type: new Abstract: Large Language Models (LLMs) hold significant promise for electrocardiogram (ECG) analysis, yet challenges remain regarding transferability, time-scale information learning, and interpretability. Current methods suffer from model-specific ECG encoders, hindering transfer across LLMs. Furthermore, LLMs struggle…

Large Language Models Imitate Logical Reasoning, but at what Cost?

arXiv:2509.12645v1 Announce Type: new Abstract: We present a longitudinal study which evaluates the reasoning capability of frontier Large Language Models over an eighteen month period. We measured the accuracy of three leading models from December 2023, September 2024 and June…

Zero-shot Graph Reasoning via Retrieval Augmented Framework with LLMs

arXiv:2509.12743v1 Announce Type: new Abstract: We propose a new, training-free method, Graph Reasoning via Retrieval Augmented Framework (GRRAF), that harnesses retrieval-augmented generation (RAG) alongside the code-generation capabilities of large language models (LLMs) to address a wide range of graph reasoning…

H$^2$R: Hierarchical Hindsight Reflection for Multi-Task LLM Agents

arXiv:2509.12810v1 Announce Type: new Abstract: Large language model (LLM)-based agents have shown strong potential in multi-task scenarios, owing to their ability to transfer knowledge across diverse tasks. However, existing approaches often treat prior experiences and knowledge as monolithic units, leading…

Learn from Global Correlations: Enhancing Evolutionary Algorithm via Spectral GNN

arXiv:2412.17629v4 Announce Type: replace-cross Abstract: Evolutionary algorithms (EAs) simulate natural selection but have two main limitations: (1) they rarely update individuals based on global correlations, limiting comprehensive learning; (2) they struggle with balancing exploration and exploitation, where excessive exploitation causes…

Convex Regularization and Convergence of Policy Gradient Flows under Safety Constraints

arXiv:2411.19193v2 Announce Type: replace-cross Abstract: This paper examines reinforcement learning (RL) in infinite-horizon decision processes with almost-sure safety constraints, crucial for applications like autonomous systems, finance, and resource management. We propose a doubly-regularized RL framework combining reward and parameter regularization…
