A signal separation view of classification
H. N. Mhaskar, Ryan O'Dowd
The problem of classification in machine learning has often been approached in terms of function approximation. In this paper, we propose an alternative approach for classification…
Learning Without Training
Ryan O'Dowd
Machine learning is at the heart of managing the real-world problems associated with massive data. With the success of neural networks on such large-scale problems, more research i…
Aspects of a Generalized Theory of Sparsity based Inference in Linear Inverse Problems
Ryan O'Dowd, Raghu G. Raj, Hrushikesh N. Mhaskar +1
Linear inverse problems are ubiquitous in various science and engineering disciplines. Of particular importance in the past few decades, is the incorporation of sparsity based prio…
Active Learning Classification from a Signal Separation Perspective
Hrushikesh Mhaskar, Ryan O'Dowd, Efstratios Tsoukanis
In machine learning, classification is usually seen as a function approximation problem, where the goal is to learn a function that maps input features to class labels. In this pap…
