Webb2 feb. 2024 · The Code For Applying Initialization Techniques In Keras Keras makes it extremely easy to use different initialization techniques in various KerasLayers, such as a Long Short Term Memory Unit or a Dense Layer with the tf.kerasAPI. The TensorFlow API provides various arguments which allow for quick prototyping. Those are: WebbThere are many layers available with some common constructor parameters: activation: Set the activation function for the layer. By default, no activation is applied. kernel_initializer and bias_initializer: The initialization schemes that create the layer’s weights (kernel and bias). This defaults to the Glorot uniform initializer.
