Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing. Such as figure 1 Shown, the present invention comprises the following steps:
[0030] A. Speed prediction
[0031] The LSTM network controls the discarding or adding of information through the "gate", so as to realize the function of forgetting or remembering. A "gate" is a structure that selectively passes information, consisting of a sigmoid function and a dot product operation. The output value of the sigmoid function is in the [0,1] interval, 0 means completely discarded, and 1 means completely passed. An LSTM network unit has three such gates, which are forget gate, input gate, and output gate. Among them, the forget gate is responsible for determining how much information is forgotten, the input gate determines how much information is added, and the output gate determines how much data is filtered and output. Its structure is as follows: figure 2 shown.
