Nettet7. aug. 2024 · If you choose to use activation=None, you for example add a BatchNormalization layer before you actually use the activation. This is used often in convolutional neural networks, but is good for dense neural networks as well. NettetThat means that by default it is a linear activation. This may work for your use-case! However, linearity is limited, and thus Keras does give us a bunch of built-in activation …
