I have published an article Classification and Regression Evaluation Metrics — Part 1. In this Part1, some of the classification evaluation metrics are explained.
The python code can be viewed at:
We need to evaluate our machine learning algorithms with the help of various metrics. There are some commonly used metrics for regression and classification problems. We will see cover some of these evaluation error metrics.The best way to analyse any key concept or problem in machine learning is to code & implement and analyse the results. I have written the classification example in Python. In this article Confusion matrix, True Negatives, False Positives, False Negatives, True Positives, sensitivity (true positive rate), specificity (true negative rate), accuracy, etc are explained
