Statistical Translation, Heat Kernels and Expected Distances
Joshua Dillon, Yi Mao, Guy Lebanon, Jian Zhang
Abstract:
High dimensional structured data such as text and images is often poorly understood and misrepresented in statistical modeling. The standard histogram representation suf- fers from high variance and performs poorly in general. We explore novel connections between statistical translation, heat kernels on manifolds and graphs, and expected dis- tances. These connections provide a new framework for unsupervised metric learning for text documents. Experiments indicate that the resulting distances are generally su- perior to their more standard counterparts.
