Deep Learning Improves Parameter Estimation in Reinforcement Learning Models

Kavli Affiliate: Marcelo Mattar | Authors: Hua-Dong Xiong, Li Ji-An, Marcelo G Mattar and Robert C Wilson | Summary: Cognitive modeling provides a formal method to articulate and test hypotheses about cognitive processes. However, accurately and reliably estimating model parameters remains challenging due to common issues in behavioral science, such as limited data, measurement noise, […]

Age-related Increase in Locus Coeruleus Activity and Connectivity with Prefrontal Cortex during Ambiguity Processing

Kavli Affiliate: Maryam Ziaei | Authors: Arjun Dave, Shuer Ye, Leona R Batz, Xiaqing Lan, Heidi Jacobs and Maryam Ziaei | Summary: Interpreting ambiguous environmental cues, like facial expressions, becomes increasingly challenging with age, especially as cognitive resources decline. Managing these challenges requires adaptive neural mechanisms that are essential for maintaining mental well-being. The locus […]

CausalAbstain: Enhancing Multilingual LLMs with Causal Reasoning for Trustworthy Abstention

Kavli Affiliate: Wei Gao | First 5 Authors: Yuxi Sun, Aoqi Zuo, Wei Gao, Jing Ma, | Summary: Large Language Models (LLMs) often exhibit knowledge disparities across languages. Encouraging LLMs to textit{abstain} when faced with knowledge gaps is a promising strategy to reduce hallucinations in multilingual settings. Current abstention strategies for multilingual scenarios primarily rely […]
