Title
Bay Area Vision Meeting: Unsupervised Feature Learning and Deep Learning
Summary
Andrew Ng presents unsupervised feature learning and deep learning, showing how algorithms can learn representations from unlabeled data instead of hand-designed features. He gives examples in vision and audio, including visualizations of features learned by successive layers.
