Keras layers API. Layers are the basic building blocks of neural networks in Keras. A layer consists of a tensor-in tensor-out computation function (the layer's call method) and some state, held in TensorFlow variables (the layer's weights).

13.02.2019 · You are running tensor flow 2.0 and it looks like VarianceScaling.init is deprecated. It might mean that Sequential will need to be more explicitly initialized in the future. for example: model = tf.keras.Sequential([ # Adds a densely-connected layer with 64 units to the model: layers.Dense(64, activation='relu', input_shape=(32,)) ...

Jun 18, 2021 · 2. Using Non-saturating Activation Functions . In an earlier section, while studying the nature of sigmoid activation function, we observed that its nature of saturating for larger inputs (negative or positive) came out to be a major reason behind the vanishing of gradients thus making it non-recommendable to use in the hidden layers of the network.
