Distributionally Robust Learning in Survival Analysis
Yeping Jin, Lauren Wise, Ioannis Ch. Paschalidis
We introduce an innovative approach that incorporates a Distributionally Robust Learning (DRL) approach into Cox regression to enhance the robustness and accuracy of survival predi…
Visually Robust Adversarial Imitation Learning from Videos with Contrastive Learning
Vittorio Giammarino, James Queeney, Ioannis Ch. Paschalidis
We propose C-LAIfO, a computationally efficient algorithm designed for imitation learning from videos in the presence of visual mismatch between agent and expert domains. We analyz…
On Value Iteration Convergence in Connected MDPs
Arsenii Mustafin, Alex Olshevsky, Ioannis Ch. Paschalidis
This paper establishes that an MDP with a unique optimal policy and ergodic associated transition matrix ensures the convergence of various versions of the Value Iteration algorith…
Smooth Ranking SVM via Cutting-Plane Method
Erhan Can Ozcan, Berk Görgülü, Mustafa G. Baydogan +1
The most popular classification algorithms are designed to maximize classification accuracy during training. However, this strategy may fail in the presence of class imbalance sinc…
