WebA possible issue with using the Pearson correlation for two dichotomous variables is that the correlation may be sensitive to the "levels" of the variables, i.e. the rates at which the variables are 1. Specifically, suppose that you think the two dichotomous variables (X,Y) are generated by underlying latent continuous variables (X*,Y*). Webcorrelation matrix of the vocal impulse response isproposed in algebraic-code-excited linearprediction (ACELP) coders. By exploring statistical characteristics, we only need to calculate a small portion of correlation coefficients before ACELP search procedure. If we further combine a pulse position prediction algorithm, we can reduce the ...
WebMay 25, 2024 · 4. Generally you want features that correlate highly with the target variable. However for prediction you need to be careful that: 1) the feature will truly be available at prediction time (i.e. there is no leakage ), and 2) that the relationship is reasonably generalizable (i.e. not relying on quirks of the training data that will not ...
