A confusion matrix is a table used to evaluate the performance of a classification model. It shows the true positives, false positives, true negatives, and false negatives.
Can you explain what true positives and false positives mean?
Sure! True positives are the cases where the model correctly predicts the positive class, while false positives are the cases where the model incorrectly predicts the positive class.
How can I use a confusion matrix to improve my model?
You can analyze the confusion matrix to identify where your model is making mistakes, allowing you to adjust your model or data to improve accuracy.
Are there any metrics derived from the confusion matrix?
