This is essentially a model that makes multiple binary classification predictions for each example. Next, let’s take a closer look at a dataset to develop an intuition for imbalanced classification problems. Typically, imbalanced classification tasks are binary classification tasks where the majority of examples in the training dataset belong to the normal class and a minority of examples belong to the abnormal class. The best model that gives me the best accuracy is the Logistic Regression model. Accuracy alone doesn't tell the full story when you're working Classification Accuracy is great, but gives us the false sense of achieving high accuracy. Consider the example of photo classification, where a given photo may have multiple objects in the scene and a model may predict the presence of multiple known objects in the photo, such as “bicycle,” “apple,” “person,” etc. Any help is appreciated. # lesson, cannot have other kinds of data structures. * Compute classification accuracy for the logistic regression model. Here is the code for the scatter matrix of iris data. This article will lay out the solutions to the machine learning skill test.
