... to face recognition are described. While most face recog- nition techniques aim at modeling faces, our goal is to model the transformation between face images of the same person. As a global face ... face transforma- tion model. In the case where we have multiple template im- ages for person P, we should combine them into a single face model ᏹ p (this would require...

With context discourse, we utilize the intuition that person names appearing similar in a document usually refers to the same person. 4.1.2 Topic Discovering A queried topic can occur within ... different qualities. For example, both topic “css test” and “test suite” are the bi-gram matching for query “css test suite”; however, the former might be more informati...

We showed that the model adapts to different ... un- derstood to correspond to entities (types, not men- tion tokens) and columns are fields, each associated with an attribute or a part of it. Our approach is based on a probab...
