What is the Accuracy?
The Accuracy is a performance metric that tells you the fraction of the predictions that were correct, without distinguishing between positive and negative predictions. The Accuracy can be a very misleading metric when the data set is unbalanced (when the prevalence is either very high or very low).
The Accuracy can be calculated as follows:
\frac{TP + TN}{TP + TN + FP + FN} = \frac{TP + TN}{P + N}
