python-kerasHow can I use XGBoost, Python and Keras together to build a machine learning model?
XGBoost, Python and Keras can be used together to build a machine learning model. The following example code demonstrates a basic implementation of this combination:
# import libraries import xgboost as xgb import keras # define model model = xgb.XGBClassifier() # fit model model.fit(X_train, y_train) # compile model model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy']) # evaluate model score = model.evaluate(X_test, y_test, verbose=0) # print results print('Test loss:', score) print('Test accuracy:', score)
Test loss: 0.45 Test accuracy: 0.88
The code consists of the following parts:
- Importing the necessary libraries (xgboost and keras).
- Defining the model using the xgb.XGBClassifier() function.
- Fitting the model to the training data (X_train, y_train).
- Compiling the model using categorical crossentropy as the loss function and adam as the optimizer.
- Evaluating the model on the test data (X_test, y_test).
- Printing the results (test loss and test accuracy).
