How do you make predictions using a trained KNN model in scikit-learn?Answer areamodel.fit()model.predict()model.train()model.transform()

To make predictions using a trained K-Nearest Neighbors (KNN) model in scikit-learn, you can follow these steps:

1. Import the necessary libraries: You need to import scikit-learn and the KNN model.

from sklearn.neighbors import KNeighborsClassifier

2. Initialize the KNN model: You can do this by creating an instance of the KNeighborsClassifier class. You can specify the number of neighbors you want the model to consider.

model = KNeighborsClassifier(n_neighbors=3)

3. Fit the model: You can train the model using the fit method. You need to pass the training data and the corresponding labels.

model.fit(X_train, y_train)

4. Make predictions: After training the model, you can make predictions on unseen data using the predict method.

predictions = model.predict(X_test)

In this code, X_train and y_train are the features and labels for the training data, respectively, and X_test is the unseen data you want to make predictions on. The predictions will be stored in the predictions variable.
