Yоu аre given а trаining dataset cоnsisting оf labeled 2D points (shown as colored points in the left image below). Each point belongs to one of two classes: red or blue. Three different classification models were trained on this dataset using different machine learning approaches. The images on the right show the decision boundaries produced by these models. In these visualizations, a dark red background represents regions classified as red, a dark blue background represents regions classified as blue, and lighter shades indicate areas where the model is less certain about its prediction. Two of these models illustrate the concepts of underfitting and overfitting. Identify which model corresponds to each problem. Traning data | Model A | Model B | Model C
