[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.
[0030] 1. Siamese network structure
[0031] Siamese network is a framework of neural network, which is used for nonlinear measurement and learning similarity information. Siamese originally meant "Siamese" or "Thai", and later it was "twin" and "siamese" in English. It was first proposed It is used to verify whether the check signature is consistent with the signature reserved in the bank, and it is applied in many fields. The Siamese network generally has two inputs, and these two inputs will enter two identical neural network structures, which can be CNN or LSTM, etc., and these two sub-networks can share weights, and finally map the input to a new space, The vector representation in the new space is formed, and then the...
