Gradient flow in recurrent nets
WebMar 16, 2024 · Depending on network architecture and loss function the flow can behave differently. One popular kind of undesirable gradient flow is the vanishing gradient. It refers to the gradient norm being very small, i.e. the parameter updates are very small which slows down/prevents proper training. It often occurs when training very deep neural … WebJul 25, 2024 · Abstract. Convolutional neural network is a very important model of deep learning. It can help avoid the exploding/vanishing gradient problem and improve the generalizability of a neural network ...

WebApr 9, 2024 · As a result, we used the LSTM model to avoid the gradual disappearing gradient by controlling the flow of the data. Additionally, the long-term dependency could be captured very easily. LSTM is a complicated system from the recurrent layer that makes use of four distinct layers for controlling data communication. WebOct 20, 2024 · The vanishing gradient problem (VGP) is an important issue at training time on multilayer neural networks using the backpropagation algorithm. This problem is worse when sigmoid transfer functions are used, in a network with many hidden layers.
