The need for annotated data is a fundamental bottleneck in developing automated prediction systems. A key strategy for reducing the reliance on human annotation is to exploit generalized information transfer, where a limited data resource is augmented with labeled data collected from related sources. 

In this talk, I will first introduce the problem of generalized information transfer, then discuss a special form of information transfer, zero-shot learning (ZSL), where knowledge is transferred between classes. For the ZSL problem, I will present a learning methodology based on discriminative non-negative matrix factorization that provides an effective approach for recognizing novel object categories in images. I will also discuss extensions that use end-to-end deep learning to achieve enhanced ZSL performance. The talk will conclude with an overview of my other work on reducing the reliance on manual annotation in machine learning.
