Statistics for Machine LearningLearn how to set the optimal threshold for your Machine Learning modelImage by author, using image files from flaticon.comTo produce a binary response, classifiers output a real-valued score that is thresholded. For example, logistic regression outputs a probability (a value between 0.0 and 1.0); and observations with a score equal to or higher than 0.5 produce a positive binary output (many other models use the 0.5 threshold by default).However, using the default 0.5 threshold is…
