Learning Sparse Representations of High Dimensional Data on Large Scale Dictionaries
Published on Jan 25, 20129786 Views
Learning sparse representations on data adaptive dictionaries is a state-of-the-art method for modeling data. But when the dictionary is large and the data dimension is high, it is a computationally c
