_accuracy(y_true, y_pred, threshold= 0.5) binary_accuracy and accuracy are two such functions in Keras.īinary_accuracy, for example, computes the mean accuracy rate across all predictions for binary classification problems. We have two classes to predict and the threshold determines the point of separation between them. A good example is building a deep learning model to predict cats and dogs. Binary classificationīinary classification metrics are used on computations that involve just two classes. Let’s look at some of the problems you may be working on. Depending on your problem, you’ll use different ones. Keras provides a rich pool of inbuilt metrics. Sometimes you need to implement your own custom metrics. Some of them are available in Keras, others in tf.keras. How you should choose those evaluation metrics?
pile(loss= 'mean_squared_error', optimizer= 'sgd', You can pass several metrics by comma separating them. In Keras, metrics are passed during the compile stage as shown below.
