Kronecker-structured Covariance Models for Multiway Data
Yu Wang, Zeyu Sun, Dogyoon Song +1
Many applications produce multiway data of exceedingly high dimension. Modeling such multi-way data is important in multichannel signal and video processing where sensors produce m…
Sample Efficient Reinforcement Learning via Low-Rank Matrix Estimation
Devavrat Shah, Dogyoon Song, Zhi Xu +1
We consider the question of learning -function in a sample efficient manner for reinforcement learning with continuous state and action spaces under a generative model. If -f…
Learning RUMs: Reducing Mixture to Single Component via PCA
Devavrat Shah, Dogyoon Song
We consider the problem of learning a mixture of Random Utility Models (RUMs). Despite the success of RUMs in various domains and the versatility of mixture RUMs to capture the het…
Deconvolution with Unknown Error Distribution Interpreted as Blind Isotonic Regression
Devavrat Shah, Dogyoon Song
Deconvolution is a statistical inverse problem to estimate the distribution of a random variable based on its noisy observations. Despite the extensive studies on the topic, deconv…
