On Myopic Sensing for Multi-Channel Opportunistic Access: Structure, Optimality, and Performance

open access: yes, 2008
We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elliot channel model).

Altered model-based prediction error signaling in the lateral orbitofrontal cortex in patients with obsessive-compulsive disorder: An fMRI study

open access: yesNeuroImage
Background: Compared to healthy individuals, patients with obsessive-compulsive disorder (OCD) are found to rely more on model-free decision-making strategies which may underlie symptom expression.

Modeling the violation of reward maximization and invariance in reinforcement schedules.

open access: yesPLoS Computational Biology, 2008
It is often assumed that animals and people adjust their behavior to maximize reward acquisition. In visually cued reinforcement schedules, monkeys make errors in trials that are not immediately rewarded, despite having to repeat error trials.

Identifying potential risk genes for clear cell renal cell carcinoma with deep reinforcement learning

open access: yesNature Communications
Clear cell renal cell carcinoma (ccRCC) is the most prevalent type of renal cell carcinoma. However, our understanding of ccRCC risk genes remains limited. This gap in knowledge poses challenges to the effective diagnosis and treatment of ccRCC.
