Spring 2023
Traditional survey based methods for clinical depression detection are not always effective; the patient may not reflect their actual mental health condition because of the cognitive bias exhibited while filling out questionnaires about depression. Established through ample earlier work, social...

Spring 2017
The work in this thesis describes advancements made towards developing main group catalysts and designing new ligands. N-Heterocyclic imine (NHI) ligands were used to support novel boron, silicon and germanium complexes. The new boron compounds demonstrated the ability to dehydrogenate...

Towards Practical Offline Reinforcement Learning: Sample Efficient Policy Selection and Evaluation
DownloadSpring 2024
Offline reinforcement learning (RL) involves learning policies from datasets, rather than online interaction. The dissertation first investigates a critical component in offline RL: offline policy selection (OPS). Given that most offline RL algorithms require careful hyperparameter tuning, we...
