Problems solved by technology

It is believed that the simple extraction and concatenation process may lose the feature relationship between variables
[0010] 2) High variance and high volatility
[0011] 3) Limited data
Therefore, the amount of data is not enough to support an overly complex model

Abstract

The invention provides a multivariate time sequence classification method based on deep learning, and the method employs a BaseCNN to capture the interaction between variables, also employs an LSTM with a long-distance dependence capability to construct a sub-network, employs the long-term memory characteristic of the sub-network, strengthens the global time sequence characteristics of a model, and helps the model to better capture the global time sequence characteristics. Besides, a three-step training mode is ingeniously designed, the functions of Center Loss and Triplet Loss are effectively played, the characteristics of volatility and specificity of the data set are processed, and good characteristic embedding is provided for a final classification network. The artificial intelligent anterior cruciate ligament auxiliary diagnosis method greatly promotes the research of the existing artificial intelligent anterior cruciate ligament auxiliary diagnosis, and has great clinical significance and practical application value.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, and more specifically, to a multivariate time series classification method based on deep learning. Background technique [0002] As one of the most complex weight-bearing joints in the human body, the knee joint bears more load during walking and sports and plays an important role in shock absorption. At the same time, knee joint injuries are also very common. Among them, anterior cruciate ligament deficiency (ACL-D) is one of the most common sports injuries. With the development of the economy and the improvement of living standards, people's demand for sports has gradually increased, followed by an increase in sports injuries. The anterior cruciate ligament (ACL) not only limits the anterior translation of the tibia, but also controls the axial rotation of the knee joint and the movement of varicose veins, and has a high value in controlling the stability of the human knee joint....
