Answer 1

Step-by-step explanation:

Figure 1). During an SFS run, the performance of each classification task is assessed using the selected fitness function. If the fitness exceeds the histogram fitness threshold, which is set to some value less than the fitness threshold stopping criterion, the histogram is incremented at those feature indices corresponding to the regions used by the classification task. This histogram is then used to generate a cumulative distribution function (cdf). Now, when regions are selected for a new classification task, features are randomly selected using the current cdf (rather than randomly selecting the features using a uniform distribution). So, rather than each feature having an equal likelihood of being selected, those features that were used in previous “successful” classification tasks have a greater likelihood of being chosen.
