Auto-DSP: Learning to Optimize Acoustic Echo Cancellers [article]

Jonah Casebeer, Nicholas J. Bryan, Paris Smaragdis
2021 arXiv   pre-print
We demonstrate our general approach on an acoustic echo cancellation task (single-talk with noise) and show that we can learn high-performing adaptive filters for a variety of common linear and non-linear  ...  Adaptive filtering algorithms are commonplace in signal processing and have wide-ranging applications from single-channel denoising to multi-channel acoustic echo cancellation and adaptive beamforming.  ...  One of the most prevalent adaptive filtering applications is acoustic echo cancellation (AEC). In this case, an adaptive filter is used to remove echo within a telecommunication system.  ...

Collaborative adaptive filtering for machine learning

Beth Jelfs, Danilo Mandic, British Council ; DAAD
Through the fusion of the outputs of adaptive filters a single collaborative hybrid filter is produced.  ...  To produce online tests for sparsity, adaptive filters for sparse environments are investigated and a unifying framework for the derivation [...]  ...  One field where algorithms for sparse systems have received much attention is in network echo cancellers, where the typical impulse response of the echo path is extremely sparse.  ...
