[PDF][PDF] Reverberant speech recognition based on denoising autoencoder.

…, H Komiyama, T Shinozaki, Y Horiuchi, S Kuroiwa - Interspeech, 2013 - isca-archive.org
Denoising autoencoder is applied to reverberant speech recognition as a noise robust front-end
to reconstruct clean speech spectrum from noisy input. In order to capture context effects …

Dimensionality reduction using non-negative matrix factorization for information retrieval

S Tsuge, M Shishibori, S Kuroiwa… - 2001 IEEE International …, 2001 - ieeexplore.ieee.org
The vector space model (VSM) is a conventional information retrieval model, which represents
