Prefrontal scaling of reward prediction error readout gates reinforcement-derived adaptive behavior in primates
Tian Sang, Yichun Huang, Fangwei Zhong +10
Reinforcement learning (RL) enables adaptive behavior across species via reward prediction errors (RPEs), but the neural origins of species-specific adaptability remain unknown. In…
Molecular Autonomous Pathfinder using Deep Reinforcement Learning
Ken-ichi Nomura, Ankit Mishra, Tian Sang +3
Diffusion in solids is a slow process that dictates rate-limiting processes in key chemical reactions. Unlike crystalline solids that offer well-defined diffusion pathways, the lac…
Outer limits of subdifferentials for min-max type functions
Andrew Eberhard, Vera Roshchina, Tian Sang
We generalise the outer subdifferential constructon suggested by Cánovas, Henrion, López and Parra for max type functions to pointwise minima of regular Lipschitz functions. We als…
Compact convex sets with prescribed facial dimensions
Vera Roshchina, Tian Sang, David Yost
While faces of a polytope form a well structured lattice, in which faces of each possible dimension are present, this is not true for general compact convex sets. We address the qu…
On the conjecture by Demyanov-Ryabova in converting finite exhausters
Tian Sang
In this paper, we prove the conjecture of Demyanov and Ryabova on the length of cycles in converting exhausters in an affinely independent setting and obtain a combinatorial reform…
