F1 Score In Confusion Matrix. Accuracy, recall, precision, and f1 scores are metrics that are used to evaluate the performance of a model. F1 score is a metric that tries to combine both precision and recall.
It is simply a ratio of correctly. Accuracy is the most intuitive performance measure.

A confusion matrix is a tabular way of visualizing the performance of your prediction model.
F1 Score Is Even More Unreliable In Such Cases, And Here Would Yield Over 97.4%, Whereas Informedness Removes Such Bias And Yields 0 As The Probability Of An Informed Decision.
Confusion matrix, precision, recall, and f1 score provides better insights into the prediction as compared to accuracy performance metrics.
