PROPS: Probabilistic personalization of black-box sequence models

1 code implementation5 Mar 2019 Michael Thomas Wojnowicz, Xuan Zhao

In particular, we construct a baseline language model by training a LSTM on the entire Wikipedia corpus of 2. 5 million articles (around 6. 6 billion words), and then use PROPS to provide lightweight customization into a personalized language model of President Donald J. Trump's tweeting.

Projecting "better than randomly": How to reduce the dimensionality of very large datasets in a way that outperforms random projections

no code implementations3 Jan 2019 Michael Wojnowicz, Di Zhang, Glenn Chisholm, Xuan Zhao, Matt Wolff

However, the recent development of randomized principal component analysis (RPCA) has opened up the possibility of obtaining approximate principal components on very large datasets.

Robust Shape Estimation for 3D Deformable Object Manipulation

1 code implementation26 Sep 2018 Tao Han, Xuan Zhao, Peigen Sun, Jia Pan

Existing shape estimation methods for deformable object manipulation suffer from the drawbacks of being off-line, model dependent, noise-sensitive or occlusion-sensitive, and thus are not appropriate for manipulation tasks requiring high precision.


On the Information Theoretic Distance Measures and Bidirectional Helmholtz Machines

no code implementations16 Jul 2018 Mahdi Azarafrooz, Xuan Zhao, Sepehr Akhavan-Masouleh

By establishing a connection between bi-directional Helmholtz machines and information theory, we propose a generalized Helmholtz machine.

Lazy stochastic principal component analysis

1 code implementation21 Sep 2017 Michael Wojnowicz, Dinh Nguyen, Li Li, Xuan Zhao

Stochastic principal component analysis (SPCA) has become a popular dimensionality reduction strategy for large, high-dimensional datasets.
