A Decoupled Data Based Approach to Stochastic Optimal Control Problems
This paper studies the stochastic optimal control problem for systems with unknown dynamics. A novel decoupled data based control (D2C) approach is proposed, which solves the problem in a decoupled "open loop-closed loop" fashion that is shown to be near-optimal. First, an open-loop deterministic trajectory optimizatio...

Multivariate Information Bottleneck
The Information bottleneck method is an unsupervised non-parametric data organization technique.

Learning a Predictable and Generative Vector Representation for Objects
What is a good vector representation of an object? We believe that it should be generative in 3D, in the sense that it can produce new 3D objects; as well as be predictable from 2D, in the sense that it can be perceived from 2D images. We propose a novel architecture, called the TL-embedding network, to learn an embedd...
