Operator Analysis and Diffusion Based Embeddings for Heterogeneous Data Fusion

When: Tue, November 4, 2014 - 3:00pm
Where: MTH 2300
Speaker: Wojciech Czaja (UMCP) -
Abstract:
As new sensing modalities emerge and the presence of multiple sensors per platform becomes widespread, it is vital to develop new algorithms and techniques which can fuse this data. Many of previous attempts to deal with the problem of heterogeneous data integration for the applications in data classification were either highly data dependent or relied on imply fusing classifier outputs. In this talk we shall examine several related approaches: graph fusion, operator fusion, and feature space fusion. They are all associated with graph diffusion processes generated by appropriately designed operators. Our results do not make any assumptions about the data and can be easily extended to new additional modalities. We shall illustrate these concepts with an example of hyperspectral imagery and lidar data fusion.

Structural change on Sparsity

When: Tue, November 11, 2014 - 3:30pm
Where: MTH 1313
Speaker: Professor Yuan Liao ( (UMCP)) -
Abstract: In the sparse modeling literature, it has been crucially assumed that the identities of important regressors are invariant across the population and across the individuals in the collected sample. In practice, however, the sparsity structure may not be always invariant in the population. For instance, the identities of important genes may be different, depending on the environmental temperature. I allow a possible structural change regarding the identities of important regressors in the population. One of the strengths is that it does not require to know whether the structural change is present, or where it occurs. We also identify the location where the possible change point occurs.
