Recognizing More Objects—Multiclass Classification
Learn how to extend the output classes beyond binary classification and identify what needs to be changed to solve a multiclass problem.
Beyond two classes
Of course, life does not always ask us to learn to classify two objects only. Even movies are not always categorized as either good or bad. That’s not how the human world operates. For instance, in an organization’s camera-based security system, 40 employees have to pass through the gates; how many classes should there be? 40, at least. One class for each individual employee. In this case, we will surely not have the same kind of neural network with one neuron in the output layer. For a multiclass classification problem, the neural network will have as many output neurons as the number of classes.
