Understanding Long Short-Term Memory (LSTM)

Long Short-Term Memory (LSTM) is a type of recurrent neural network (RNN) specifically designed to model sequences and time-series data. Traditional recurrent neural networks (RNNs) face challenges in learning long-term dependencies due to vanishing gradients, but Long Short-Term Memory (LSTM) addresses this issue with a specialized cell architecture that includes gates to control information flow. Key components of a Long Short-Term Memory (LSTM) cell include the cell state, hidden state, forget gate, input gate, and output gate.

Key Components of a Long Short-Term Memory (LSTM) Cell

• Cell State (C_t): The memory of the network, which carries information across time steps.
• Hidden State (h_t): The output of the Long Short-Term Memory (LSTM) cell at each time step.
• Forget Gate: Decides which portion of the cell state to discard.
• Input Gate: Determines which new information to add to the cell state.
• Output Gate: Controls the part of the cell state that is output as the hidden state.
