Revisiting Design Choices in Proximal Policy Optimization
Chloe Ching-Yun Hsu, Celestine Mendler-Dünner, Moritz Hardt
Proximal Policy Optimization (PPO) is a popular deep policy gradient algorithm. In standard implementations, PPO regularizes policy updates with clipped probability ratios, and par…
Linear Dynamics: Clustering without identification
Chloe Ching-Yun Hsu, Michaela Hardt, Moritz Hardt
Linear dynamical systems are a fundamental and powerful parametric model class. However, identifying the parameters of a linear dynamical system is a venerable task, permitting pro…
A new algorithm for fast generalized DFTs
Chloe Ching-Yun Hsu, Chris Umans
We give an new arithmetic algorithm to compute the generalized Discrete Fourier Transform (DFT) over finite groups . The new algorithm uses operations to c…
The prism manifold realization problem
William Ballinger, Chloe Ching-Yun Hsu, Wyatt Mackey +3
The spherical manifold realization problem asks which spherical three-manifolds arise from surgeries on knots in . In recent years, the realization problem for C, T, O, and I-…
