Linguistic Geometries for Unsupervised Dimensionality Reduction
Yi Mao, Krishnakumar Balasubramanian, Guy Lebanon
Text documents are complex high dimensional objects. To effectively visualize such data it is important to reduce its dimensionality and visualize the low dimensional embedding as…
Unsupervised Supervised Learning II: Training Margin Based Classifiers without Labels
Krishnakumar Balasubramanian, Pinar Donmez, Guy Lebanon
Many popular linear classifiers, such as logistic regression, boosting, or SVM, are trained by optimizing a margin-based risk function. Traditionally, these risk functions are comp…
Asymptotic Analysis of Generative Semi-Supervised Learning
Joshua V Dillon, Krishnakumar Balasubramanian, Guy Lebanon
Semisupervised learning has emerged as a popular framework for improving modeling accuracy while controlling labeling cost. Based on an extension of stochastic composite likelihood…
