13.05.2021 · By default, we assume that y_pred encodes a probability distribution. reduction. Type of tf.keras.losses.Reduction to apply to loss. Default value is AUTO. AUTO indicates that the reduction option will be determined by the usage context. For almost all cases this defaults to SUM_OVER_BATCH_SIZE.

Mar 19, 2019 · The new ("keras as the default API") approach would have you use the keras layer tf.keras.layers.Flatten but there is a little nuance you seem to have missed (and that hasn't been mentioned in the comments). tf.keras.layers.Flatten() actually returns a keras layer (callable) object which in turn needs to be called with your previous layer.
Use this crossentropy loss function when there are two or more label classes. We expect labels to be provided as integers. If you want to provide labels using one-hot representation, please use CategoricalCrossentropy loss. There should be # classes floating point values per feature for y_pred and a single floating point value per feature for y ...
