Which of the following does not belong to long-term memory LSTM (long Short稵erm Memory) network architecture?

The correct answer is A. Memory door. Option A, "Memory door (gate)," is not a component of standard LSTM architecture - LSTMs have exactly three gates: the forget gate, the input gate, and the output gate, and no gate called a "memory gate" exists. The forget gate (B) is real: it decides what information to…

Explanation

Option A, "Memory door (gate)," is not a component of standard LSTM architecture - LSTMs have exactly three gates: the forget gate, the input gate, and the output gate, and no gate called a "memory gate" exists. The forget gate (B) is real: it decides what information to discard from the cell state using a sigmoid activation. The input gate (C) is real: it controls what new information gets written into the cell state. The output gate (D) is real: it determines what portion of the cell state is exposed as the hidden state output. Memory tip: remember F-I-O (Forget, Input, Output) - three gates, three letters - if a question introduces a fourth gate like "memory gate," it's the impostor.
