Continual learning regularization may hinder financial ASR performance, study finds

By PulseAugur Editorial · [1 sources] ·

A new research paper investigates the effectiveness of continual learning regularization techniques, specifically Elastic Weight Consolidation (EWC) and mini-KFAC, on Automatic Speech Recognition (ASR) systems used for transcribing financial earnings calls. The study found that adapting a general-domain ASR model like Whisper-small to the Earnings22 benchmark resulted in improved performance on new financial speech data, rather than catastrophic forgetting. This suggests that task complementarity can make regularization counterproductive in this specific scenario. However, when regularization is necessary, a layer-wise mini-KFAC approximation demonstrated lower word error rates and more stable optimization compared to standard diagonal EWC. AI

IMPACT This research suggests that the application of continual learning techniques in financial speech recognition may require careful consideration of task complementarity to avoid counterproductive outcomes.
