Random forests, or random decision forests, are supervised classification algorithms that use a learning method consisting of a multitude of decision trees. The output is the consensus of the best answer to the problem.
One way to describe the philosophy behind the random forest is that since the random trees have some overlap, engineers can build systems to study data redundantly with the various trees and look for trends and patterns that support a given data outcome. For example, if five random trees provi...
Since the random forest model is made up of multiple decision trees, it would be helpful to start by describing the decision tree algorithm briefly. Decision trees start with a basic question, such as, “Should I surf?” From there, you can ask a series of questions to determine an answer...

Random sampling of living individuals should therefore be preferred whenever researchers are interested in studying disease circulation in natural populations [22]. However, sampling living, free-ranging animals is a challenging endeavour, and biologists and veterinarians need to cope with several issues ...
