[3] minimizes the mean square distance between the two embeddings, ensures the standard deviation of each element remains above a threshold, and reduces the covariances between each pair of embedding variables toward zero. Both methods project the representation vectors into a high-dimensional space ...
(red, right) proteins; (C–H): SSEs (y-axis) of Normics and VSN across the stochastically varied range of the respective parameters (x-axis); each dot represents a different simulation (N = 250); the dashed line in subplot D denotes the theoretical threshold (as explained in the text...
By considering the mechanics of DDCAL, outliers above or below a threshold are the first generated clusters. After every iteration, these outliers are removed continuously from the input list and assigned to clusters. Through this procedure, the input list becomes more evenly distributed. DDCAL ...

There are no standard threshold values for the percentage of COV and it commonly depends on the field of study. For this study, we consider the percent of COV of less than 10% to be significantly low variability, less than 20% to be marginally low variability and less than 30% to be ...
