Nonparametric Sparsity and Regularization
(2011-09-26)
In this work we are interested in the problems of supervised learning and variable selection when the input-output dependence is described by a nonlinear function depending on a few variables. Our goal is to consider a ...
Multi-Class Learning: Simplex Coding And Relaxation Error
(2011-09-27)
We study multi-category classification in the framework of computational learning theory. We show how a relaxation approach, which is commonly used in binary classification, can be generalized to the multi-class setting. ...
Multiscale Geometric Methods for Data Sets I: Multiscale SVD, Noise and Curvature
(2012-09-08)
Large data sets are often modeled as being noisy samples from probability distributions in R^D, with D large. It has been noticed that oftentimes the support M of these probability distributions seems to be well-approximated ...
Cicada: Predictive Guarantees for Cloud Network Bandwidth
(2014-03-24)
In cloud-computing systems, network-bandwidth guarantees have been shown to improve predictability of application performance and cost. Most previous work on cloud-bandwidth guarantees has assumed that cloud tenants know ...
iBCM: Interactive Bayesian Case Model Empowering Humans via Intuitive Interaction
(2015-04-01)
Clustering methods optimize the partitioning of data points with respect to an internal metric, such as likelihood, in order to approximate the goodness of clustering. However, this internal metric does not necessarily ...
Planning Robust Strategies for Constructing Multi-object Arrangements
(2017-01-30)
A crucial challenge in robotics is achieving reliable results in spite of sensing and control uncertainty. A prominent strategy for dealing with uncertainty is to construct a feedback policy, where actions are chosen as a ...
