LSTM Memory Cell
Fundamental computational unit of LSTM networks that maintains a long-term memory state through recurrent connections and gate mechanisms controlling the writing, reading, and forgetting of information.
Reset Gate (GRU)
Component of GRUs that determines how much of the previous hidden state to forget when computing the new candidate content, allowing the model to control the amount of past information relevant to the current prediction.
Update Gate (GRU)
Mechanism in GRUs that combines the functionality of LSTM's forget and input gates, controlling the balance between preserving the previous hidden state and incorporating the new candidate content into the current state.
Seq2Seq Architecture
Neural structure composed of an encoder (often LSTM/GRU) that transforms an input sequence into a context vector and a decoder that generates an output sequence, widely used for machine translation and text generation.
Truncated Backpropagation Through Time (TBPTT)
Variant of backpropagation through time that limits gradient propagation to a fixed number of time steps, reducing computational complexity and mitigating gradient problems while capturing short to medium-term dependencies.
