Scalable Safe Multi-Agent Reinforcement Learning for Multi-Agent System
[ "cs.MA", "cs.AI" ]
Safety and scalability are two critical challenges faced by practical Multi-Agent Systems (MAS). However, existing Multi-Agent Reinforcement Learning (MARL) algorithms that rely solely on reward shaping are ineffective in ensuring safety, and their scalability is rather limited due to the fixed-size network output. To ...

Pseudocode-Injection Magic: Enabling LLMs to Tackle Graph Computational Tasks
[ "cs.CL", "cs.AI" ]
Graph computational tasks are inherently challenging and often demand the development of advanced algorithms for effective solutions. With the emergence of large language models (LLMs), researchers have begun investigating their potential to address these tasks. However, existing approaches are constrained by LLMs' lim...

A dimensionality reduction technique based on the Gromov-Wasserstein distance
[ "stat.ML", "cs.LG" ]
Analyzing relationships between objects is a pivotal problem within data science. In this context, Dimensionality reduction (DR) techniques are employed to generate smaller and more manageable data representations. This paper proposes a new method for dimensionality reduction, based on optimal transportation theory and...
