What is model evaluation metrics?
Let us now define the evaluation metrics for evaluating the performance of a machine learning model, which is an integral component of any data science project. It aims to estimate the generalization accuracy of a model on the future (unseen/out-of-sample) data.
What are the metrics chosen to evaluate model performance?
Accuracy : the proportion of the total number of predictions that were correct. Positive Predictive Value or Precision : the proportion of positive cases that were correctly identified. Negative Predictive Value : the proportion of negative cases that were correctly identified.
What are the different types of evaluation metrics?
This post is about various evaluation metrics and how and when to use them.
- Accuracy, Precision, and Recall: A. ...
- F1 Score: This is my favorite evaluation metric and I tend to use this a lot in my classification projects. ...
- Log Loss/Binary Crossentropy. ...
- Categorical Crossentropy. ...
- AUC.
What metric can you use to evaluate a classification model?
Area Under Curve(AUC) is one of the most widely used metrics for evaluation. It is used for binary classification problem. AUC of a classifier is equal to the probability that the classifier will rank a randomly chosen positive example higher than a randomly chosen negative example.
