Max-Entropy Reinforcement Learning with Flow Matching and A Case Study on LQR

arXiv:2512.23870v1 Announce Type: new Abstract: Soft actor-critic (SAC) is a popular algorithm for max-entropy reinforcement learning. In practice, the energy-based policies in SAC are often approximated using simple policy classes for efficiency, sacrificing the expressiveness and robustness. In this paper,…

Secure and Efficient Access Control for Computer-Use Agents via Context Space

arXiv:2509.22256v3 Announce Type: replace-cross Abstract: Large language model (LLM)-based computer-use agents represent a convergence of AI and OS capabilities, enabling natural language to control system- and application-level functions. However, due to LLMs’ inherent uncertainty issues, granting agents control over computers…

An Empirical Study of Methods for Small Object Detection from Satellite Imagery

arXiv:2502.03674v2 Announce Type: replace-cross Abstract: This paper reviews object detection methods for finding small objects from remote sensing imagery and provides an empirical evaluation of four state-of-the-art methods to gain insights into method performance and technical challenges. In particular, we…

Deep sequence models tend to memorize geometrically; it is unclear why

arXiv:2510.26745v2 Announce Type: replace Abstract: Deep sequence models are said to store atomic facts predominantly in the form of associative memory: a brute-force lookup of co-occurring entities. We identify a dramatically different form of storage of atomic facts that we…

Tazza: Shuffling Neural Network Parameters for Secure and Private Federated Learning

arXiv:2412.07454v3 Announce Type: replace Abstract: Federated learning enables decentralized model training without sharing raw data, preserving data privacy. However, its vulnerability towards critical security threats, such as gradient inversion and model poisoning by malicious clients, remain unresolved. Existing solutions often…

Learning Network Dismantling Without Handcrafted Inputs

arXiv:2508.00706v2 Announce Type: replace Abstract: The application of message-passing Graph Neural Networks has been a breakthrough for important network science problems. However, the competitive performance often relies on using handcrafted structural features as inputs, which increases computational cost and introduces…
