11. We briefly review Hochreiter's (1991) analysis of this problem, then address it by introducing a novel, efficient, gradient based method called long short-term memory (LSTM).
12. LSTM also solves complex, artificial long-time-lag tasks that have never been solved by previous recurrent network algorithms.
13. LSTM networks were introduced in the late 1990s for sequence prediction, which is considered one of the most complex DL tasks.
14. In the case of an LSTM, for each element in the sequence, there is a corresponding hidden state \(h_t\), which in principle can contain information from arbitrary points earlier in the sequence.

30. The LSTM worked well — for a while.
31. It is still a recurrent network, so if the input sequence has 1000 characters, the LSTM cell is called 1000 times, a long gradient path.
32. A common LSTM unit is composed of a cell, an input gate, an output gate and a forget gate.
