The statistical argument depends on suitable corruption assumptions; the 2018 paper demonstrates image restoration tasks, while the same principle can be considered for speech when valid noisy pairs are available.

Jin Dive

Noise2Noise showed that a model can learn restoration from corrupted input-target pairs rather than clean targets. For a squared-error objective, the optimal prediction is the conditional mean of the target given the input. If target corruption has zero conditional mean given the input and shares the same underlying clean signal, this mean can equal the clean signal. These assumptions are important: correlated or biased corruptions can remain in the learned estimate. The original paper demonstrated photographic noise removal, synthetic Monte Carlo denoising, and undersampled MRI reconstruction; applying the method to speech likewise requires suitably paired noisy versions of the same utterance.

Kí ni Noise2Noise Speech Enhancement?

Noise2Noise trains a restoration model from pairs of corrupted observations of the same underlying signal, without requiring a clean target. The statistical argument depends on suitable corruption assumptions; the 2018 paper demonstrates image restoration tasks, while the same principle can be considered for speech when valid noisy pairs are available.

For squared-error training, what conditional statistic minimizes expected loss?

Expected squared error is minimized by the conditional mean; with suitable paired-corruption assumptions, it can match the clean signal.

For absolute-error training, which conditional statistic is minimized?

Expected absolute error is minimized at a conditional median; this does not guarantee clean recovery without suitable corruption assumptions.
