Analysis of Intensive Utilization Potential of Industrial Land at Enterprise Scale

2018

Industrial land is an important part of urban resources, and extensive development can seriously hinder the process of urbanization. In order to meet the demand for larger-scale and higher-quality urban economic growth using limited land …

Cascaded Attention: Adaptive and Gated Graph Attention Network for Multiagent Reinforcement Learning

2022 · IEEE Transactions on Neural Networks and Learning Systems

Modeling the interactive relationships of agents is critical to improving the collaborative capability of a multiagent system. Some methods model these by predefined rules. However, due to the nonstationary problem, the interactive relationship changes over …

Quantifying predictive uncertainty of aphasia severity in stroke patients with sparse heteroscedastic Bayesian high-dimensional regression

2023 · arXiv (Cornell University)

Sparse linear regression methods for high-dimensional data commonly assume that residuals have constant variance, which can be violated in practice. For example, Aphasia Quotient (AQ) is a critical measure of language impairment and informs treatment …

Last-Iterate Convergence in Adaptive Regret Minimization for Approximate Extensive-Form Perfect Equilibrium

2025 · arXiv (Cornell University)

The Nash Equilibrium (NE) assumes rational play in imperfect-information Extensive-Form Games (EFGs) but fails to ensure optimal strategies for off-equilibrium branches of the game tree, potentially leading to suboptimal outcomes in practical settings. To address …
