The FeatureSelector includes some of the most common feature selection methods:. If your model experiences excessive zero crossings, you can increase this parameter to increase the threshold at which Simulink software triggers the Consecutive zero-crossings violation diagnostic. To find the sum, the formula we must remember is sum = average * number of values. Instead, therefore, perhaps consider making a Python dictionary, where keys are cell values, and values are a list of sequence identifier pairs.
