Noise-aware training for analog hardware: accuracy collapses at a threshold rather than degrading smoothly [D]
Analog in-memory compute is experiencing renewed interest due to its potential for energy efficiency, yet noise remains a persistent challenge. Recent experimentation reveals a surprising characteristic of analog AI degradation: accuracy doesn't diminish gradually with noise, but rather collapses abruptly past a specific threshold. Intriguingly, noise-aware training—introducing noise during the training process—can significantly elevate this threshold. This suggests flatter minima are crucial, though alternative explanations are being explored. See "Comparing embedding models with synthetic query probing" for related insights into model evaluation.
