Hey @PriyankaSharma0925,

The model.evaluate() method evaluates a model.

This means asking the question "how well is our model doing?"

When fit a model to a dataset (using model.fit()) it learns patterns in that data.

When we call model.evaluate() we're asking, how good are those patterns the model learned in the data.

For example, a model will fit on training data: model.fit(X_train, y_train)

And then we will evaluate it on testing data (data it has never seen before): model.evaluate(X_test, y_test)

We evaluate to see how well the patterns it learned on the training data generalize to unseen data.
