Rethinking Non-Negative Matrix Factorization with Implicit Neural Representations

1 code implementation5 Apr 2024 Krishna Subramani, Paris Smaragdis, Takuya Higuchi, Mehrez Souden

Non-negative Matrix Factorization (NMF) is a powerful technique for analyzing regularly-sampled data, i. e., data that can be stored in a matrix.

Noise-Robust DSP-Assisted Neural Pitch Estimation with Very Low Complexity

no code implementations25 Sep 2023 Krishna Subramani, Jean-Marc Valin, Jan Buethe, Paris Smaragdis, Mike Goodwin

Pitch estimation is an essential step of many speech processing algorithms, including speech coding, synthesis, and enhancement.

Unsupervised Improvement of Audio-Text Cross-Modal Representations

1 code implementation3 May 2023 Zhepei Wang, Cem Subakan, Krishna Subramani, Junkai Wu, Tiago Tavares, Fabio Ayres, Paris Smaragdis

In this paper, we study unsupervised approaches to improve the learning framework of such representations with unpaired text and audio.
