Carbon emissions are getting more and more attention. Forecasting is a relatively difficult prediction, and the randomness is relatively large. The long-term and short-term neural network is an improved RNN neural network, which overcomes the problem of gradient explosion. Passenger flow data is also a kind of time Sequence data, using LSTM neural network for prediction, with higher accuracy
Abstract
LSTM principle, MATALB programming long-term and short-term neural network LSTM passenger flow prediction.

Basic definition of LSTM

LSTM is a type of neural network that contains LSTM blocks (blocks) or others. In literature or other materials, LSTM blocks may be described as intelligent network units because they can memorize values ​​of indefinite length of time. There is a The gate can determine whether the input is important enough to be remembered and whether it can be output.
There are four S function units at the bottom of Figure 1. The leftmost function may become the input of the block according to the situation. The three on the right will pass through the gate to determine whether the input can be passed to the block. The second on the left is the input gate. If the output here is similar If it is at zero, the value here will be blocked and will not enter the next layer. The third one from the left is the forget gate, when this produces a value close to zero, the value remembered in the block will be forgotten. The fourth and rightmost input is the output gate, which can determine whether the input in the block memory can be output.
