Improving Classification When a Class Hierarchy is Available Using a Hierarchy-Based Prior
We introduce a new method for building classification models when we have prior knowledge of how the classes can be arranged in a hierarchy, based on how easily they can be distinguished. The new method uses a Bayesian form of the multinomial logit (MNL, a.k.a. “softmax”) model, with a prior that introduces correlations between the parameters for classes that are nearby in the tree. We compare ...

Improving classification models when a class hierarchy is available Babak Shahbaba Doctor of Philosophy Graduate Department of Public Health Sciences University of Toronto 2007 We introduce a new method for modeling hierarchical classes, when we have prior knowledge of how these classes can be arranged in a hierarchy. The application of this approach is discussed for linear models, as well as n...
متن کاملClass-Based Probability Estimation Using a Semantic Hierarchy
This article concerns the estimation of a particular kind of probability, namely, the probability of a noun sense appearing as a particular argument of a predicate. In order to overcome the accompanying sparse-data problem, the proposal here is to define the probabilities in terms of senses from a semantic hierarchy and exploit the fact that the senses can be grouped into classes consisting of ...
متن کاملObject Classification Using a Semantic Hierarchy
We consider the problem of object classification by exploiting the hierarchy structure of object categories. Our proposed method first train a collection of binary classifiers to differentiate pairs of object categories at different levels of the object hierarchy. Then we use the outputs of these classifiers and the object hierarchy to define a new image representation. Our experimental results...
متن کاملImproving Text Classification by Shrinkage in a Hierarchy of Classes
When documents are organized in a large number of topic categories, the categories are often arranged in a hierarchy. The U.S. patent database and Yahoo are two examples. This paper shows that the accuracy of a naive Bayes text classi er can be signi cantly improved by taking advantage of a hierarchy of classes. We adopt an established statistical technique called shrinkage that smoothes parame...
