LSTM Key Innovation
medium
LSTMs were designed to address the limitations of vanilla RNNs. What is their key innovation?
A
They introduce attention mechanisms that allow the network to focus on relevant parts of the sequence regardless of their distance
B
They introduce gating mechanisms — input, forget, and output gates — that control what information is stored, discarded, or read from a cell state
C
They introduce separate weight matrices for short-term and long-term dependencies, processed in parallel at each time step
D
They introduce skip connections between non-adjacent time steps, allowing gradients to flow directly across long distances
