BEST-RQ-2: Contextualize-Then-Predict, a Two-Step Approach for Self-Supervised Audio Representations

arXiv:2606.30700v1 Announce Type: cross Abstract: Self-supervised learning enables audio representations that transfer across domains and tasks. We present BEST-RQ-2, an evolution of BEST-RQ that retains frozen randomprojection-based discrete targets while introducing a two-step contextualize-then-predict pretraining scheme. A ViT context encoder processes only the unmasked spectrogram regions, and a lightweight predictor infers targets for the masked regions; the predictor is discarded after pretraining. Replacing the original Conformer encoder with a ViT shifts performance across domains, sl
The continuous evolution of self-supervised learning techniques in AI, driven by increasing computational capabilities and a demand for more efficient data utilization, makes this development timely.
This new method streamlines the pretraining process for audio AI, potentially leading to more advanced and efficient AI models for various audio-related applications.
The adoption of a two-step contextualize-then-predict approach with a Vision Transformer (ViT) allows for more efficient self-supervised learning in audio, potentially reducing computational overhead and improving model performance across domains.
