Extended Data Fig. 3. Matching standardized noise level v of training and test data.

Same as Fig. 2e-g, but with each column (testing level) normalized in order to highlight that the optimal training level for each testing noise level lies close to the diagonal. The correlation (a) was normalized by the maximum of each column, while error and bias metrics have been normalized by the minimum of each column. v in units of standardized noise, % · Hz ^−1/2.
