Pruning Whisper-small improves ASR accuracy by acting as a regularizer

By PulseAugur Editorial · [1 sources] ·

Researchers have demonstrated that neural network pruning can act as a regularization technique for Automatic Speech Recognition (ASR) systems, rather than just a method for compression. By analyzing the sensitivity of different components within the Whisper-small model, they found that pruning specific layers, such as decoder self-attention or the last encoder layers, can actually improve generalization and reduce Word Error Rate (WER). This approach allows for more aggressive compression without significant accuracy loss, suggesting pruning can be a valuable architectural design tool. AI

IMPACT Suggests pruning can be used as a design tool to improve model generalization and compression, potentially impacting future ASR model development.

    Pruning as Regularization: Sensitivity-Aware One-Shot Pruning in ASR

    arXiv:2511.08092v2 Announce Type: replace-cross Abstract: We challenge the conventional view of neural network pruning as solely a compression technique, demonstrating that one-shot magnitude pruning serves as a powerful implicit regularizer for ASR. Using Whisper-small, we combi…
