  F1 score is a metric used to measure the accuracy of a model in a classification problem. It is the harmonic mean of precision and recall, and is calculated by taking the average of true positives and true negatives divided by the sum of false positives and false negatives. The higher the F1 score, the better the model is at predicting correctly.
