Feature Selection for Short Text Classification using Wavelet Packet Transform

Text classification tasks suffer from curse of dimensionality due to large feature space. Short text data further exacerbates the problem due to their sparse and noisy nature. Feature selection thus becomes an important step in improving the classification performance. In this paper, we propose a novel feature selection method using Wavelet Packet Transform. Wavelet Packet Transform (WPT) has b...
