I try hard to convince friends, colleagues and students to get started in deep learning and bold statements like the […]

Last Updated on August 27, 2020 A powerful and popular recurrent neural network is the long short-term model network or LSTM. It is widely used because the architecture overcomes the vanishing and exposing gradient problem that plagues all recurrent neural networks, allowing very large and very deep networks to be created. Like other recurrent neural networks, LSTM networks maintain state, and the specifics of how this is implemented in Keras framework can be confusing. In this post you will discover […]
