Spectral Bridge - Cognizance 2026
IIT Roorkee
📌 About the Event
Spectral Bridge challenges participants to reconstruct missing audio signals from fragmented spectral data. The task involves Few-Shot Signal In-Painting, where models must infer spectral structure from limited context and predict missing waveform values using amortized inference. The dataset contains 80,000 unique non-stationary audio clips, requiring adaptive learning rather than global averaging.
