End-to-end models for robust automatic speech recognition (ASR) have not been sufficiently well-explored in prior work. With end-to-end models, one could choose to preprocess the input speech using speech enhancement techniques and train the model using enhanced speech. Another alternative is to pas…
In this paper, various regularizations on the room impulse response (RIR) are proposed to obtain better single-channel speech dereverberation in the non-negative matrix factorization (NMF) framework. The regularizations on the RIR are motivated by the spectral domain representation of the RIR. To ob…
Imaging techniques involve counting of photons striking a detector. Due to fluctuations in the counting process, the measured photon counts are known to be corrupted by Poisson noise. In this paper, we propose a blind dictionary learning framework for the reconstruction of photographic image data fr…
