AI Researcher, Cognitive Technologist Inventor - AI Thinking, Think Chain Innovator - AIOT, XAI, Autonomous Cars, IIOT Founder Fisheyebox Spatial Computing Savant, Transformative Leader, Industry X.0 Practitioner Why do we need #ConfusionMatrix? Generally, It's a tool that helps to understand if the model is working really well. Moreover, from it, you can derive many evaluation measures, such as accuracy, precision, recall, etc. It's based on the fact that we need to compare the class predicted by the classifier with the actual class for each observation. So, the efficiency of a model can be seen using this amazing matrix. Each column corresponds to the predicted class, while each row indicates the actual class.
