Gated Recurrent Unit (GRUs).
Gated Recurrent Units(GRUs) Table Of Contents: Disadvantages Of LSTM Networks. What Is GRU? Why We Need GRU Neural Network? (1) Disadvantages Of LSTM Networks. Computational Complexity: LSTM networks are more computationally complex compared to simpler architectures like feedforward neural networks or basic RNNs. This complexity arises due to the presence of multiple gates, memory cells, and additional parameters. As a result, training and inference can be more computationally expensive and time-consuming, especially for large-scale models and datasets. Memory Requirement: LSTM networks require more memory to store the additional parameters and memory cells. This can pose challenges when working with limited

Long Short Term Memory Network.
Long Short Term Memory Network Table Of Contents: Introduction To LSTM. (1) Problem With ANN Problem-1: Sequence Is Lost The problem with ANN architecture is that its design is unable to process sequential information. When we pass sequential information to the ANN network we have to pass everything at a time. When we pass every word at a time It’s sequence will be lost in the process. We will not be able to know which word comes after what. Problem-2: Fixed Input Size. The problem with ANN is that it has a fixed input size. It will not be able
