Learning with Output Kernels and Latent Kernels    (Slides)

Abstract:
Kernels provide a finite representation of abstract feature mappings, which is an invaluable modeling tool in computational data analysis. Although kernel methods are frequently applied to input representations, particularly when learning functions, much less work has considered applying kernels to output representations or representations of latent structure. In this talk, I will discuss some new applications of kernel methods to both output and latent representations. I will first discuss how losses beyond squared error can be exactly and efficiently accommodated within output kernels. Then I will discuss how kernel methods can be extended to partially supervised learning problems, such as latent representation discovery. Such kernel based extensions are able to achieve state of the art results in robust regression, multi-label classification, and hidden-layer network training.
