Optimization tools are vital to data analysis and learning. The optimization perspective has provided valuable insights, and optimization formulations have led to practical algorithms with good theoretical properties. In turn, the rich collection of problems in learning and data analysis is providin ...

This talk presents techniques for nonstationarity detection in the context of speech and audio waveforms, with broad application to any class of time series that exhibits locally stationary behavior. Many such waveforms, in particular information-carrying natural sound signals, exhibit a degree of c ...

Optimization provides a valuable framework for thinking about,
formulating, and solving many problems in machine learning. Since
specialized techniques for the quadratic programming problem arising
in support vector classification were developed in the 1990s, there
has been more and more cross-ferti ...

The use of optimization as a framework for formulating machine learning problems has become much more widespread in recent years. In some cases, the demands of the machine learning problems go beyond the scope of traditional optimization paradigms. While existing optimization formulations and algori ...

This paper studies the problem of simultaneously aligning a batch of linearly correlated images despite gross corruption (such as occlusion). Our method seeks an optimal set of image domain transformations such that the matrix of transformed images can be decomposed as the sum of a sparse matrix of ...

The combination of Semantic Web and Grid technologies and architectures eases the development of applications that share heterogeneous resources (data and computing elements) that belong to several organisations. The Aerospace domain has an extensive and heterogeneous network of facilities and insti ...

We consider the problem of recovering a complete (i.e., square and invertible) dictionary mbA0, from mbY=mbA0mbX0 with mbY∈Rn×p. This recovery setting is central to the theoretical understanding of dictionary learning. We give the first efficient algorithm that provably recovers mbA0 when mbX0 has O ...
