WebJan 7, 2024 · loss: 1.1836 - binary_accuracy: 0.7500 - true_positives: 9.0000 - true_negatives: 9.0000 - false_positives: 3.0000 - false_negatives: 3.0000, this is what I got after training, and since there are only 12 samples in the test, it is not possible that there are 9 true positive and 9 true negative – ColinGuolin Jan 7, 2024 at 21:08 1 WebJul 17, 2024 · If you choose metrics= ['accuracy'], Keras automatically infers the accuracy metric according to the loss function. Four your case, since the loss function is BinaryCrossentropy, Keras has already chosen the metrics= ['BinaryAccuracy'].
