Random uniform initializer keras

Webb10 apr. 2024 · Traditionally, random initialization (e.g., using Gaussian or uniform distributions) has been the go-to method for setting initial weights. However, this approach can lead to a variety of issues, such as vanishing or exploding gradients, which can slow down the training process or even prevent convergence altogether. WebbKeras initializers are the keyword arguments which is used for passing initializers for layers that depend on the layer. Usually, we can say it is a bias initializer and kernel initializer. The keras initialization will define the way for setting initial random weights onto the layers of keras. Training the neural network completely depended on ...

Webb16 juni 2024 · Secondly, in keras, the default weight initializer for Convolution, Dense and RNN-GRU/LSTM is glorot_uniform, also known as Xavier uniform initializer. And the default bias initializer is zeros. If you follow the source code of LSTM (in your case), you would find them. About it, according to the doc WebbBy default, PyTorch initializes weight and bias matrices uniformly by drawing from a range that is computed according to the input and output dimension.
