Enhanced sparse representation classifier for text classification

作者:

Highlights:

• Empirical demonstration of Sparse classification methods on text data.

• Minimum residual error and class wise dictionaries based methods are most efficient.

• Proposed a dynamic dictionary refinement algorithm.

• Proposed work improves computational speed and classification performance.

• Dictionary refinement procedure addressed the problem of over-reliance on training data.
