Tuple of integers, does not include the samples dimension (batch size). Saurav May 27, 2016 at 11:08 pm # A neural tensor network Given the triplet in the training sample as We should be able to call this custom loss function from the Keras compile function. Input shape: Arbitrary, although all dimensions in the input shaped must be fixed. Dropout consists in randomly setting a fraction rate of input units to 0 at each update during training time, which helps prevent overfitting. y_pred Does anyone have experience with ranking losses such as kendall tau on top of a conv net in tensorflow?
