A recurrent network architecture with gating mechanisms that decide what information to remember, forget, or output at each step. LSTMs solved the vanishing-gradient problem that plagued plain RNNs and dominated language and time-series modeling for years. Transformers eventually surpassed LSTMs on most benchmarks, but the architecture remains useful in narrow settings.

Why Long Short-Term Memory Matters for Your AI or Cybersecurity Career

Many production systems still run on LSTM-based models. Knowing the architecture and its tradeoffs is useful when working on sequence tasks where transformers are overkill.
