Data Representation and Compression Using Linear-Programming Approximations

no code implementations20 Nov 2015 Hristo S. Paskov, John C. Mitchell, Trevor J. Hastie

We also discuss how to derive features from the compressed documents and show that while certain unregularized linear models are invariant to the structure of the compressed dictionary, this structure may be used to regularize learning.

Learning Mixed Graphical Models

no code implementations22 May 2012 Jason D. Lee, Trevor J. Hastie

We present a new pairwise model for graphical models with both continuous and discrete variables that is amenable to structure learning.

One sketch for all: Theory and Application of Conditional Random Sampling

no code implementations NeurIPS 2008 Ping Li, Kenneth W. Church, Trevor J. Hastie

Conditional Random Sampling (CRS) was originally proposed for efficiently computing pairwise ($l_2$, $l_1$) distances, in static, large-scale, and sparse data sets such as text and Web data.
