Abstract

Abstract:

Based on Convolutional Long-Short Term Memory Neural Network, the authors proposed a deep learning method PressureConvLSTM to extract features during walking in both spatial and temporal dimensions. Classification based on plantar pressure of anterior cruciate ligament deficiency (ACLD) was applied to distinguish walking gait information. Experiment results combined with clinical data showed that PressureConvLSTM model obtained 95% test accuracy when diagnosing ACLD, which was well performed over other traditional deep learning models.

Key words: intelligent diagnosis, anterior cruciate ligament deficiency (ACLD), plantar pressure, deep learning; ConvLSTM neural network

摘要：

提出一种基于卷积长短期记忆神经网络的深度学习模型PressureConvLSTM, 用来提取行走过程中足底压力的空间特征和时序特征, 并进行步态分类。通过对前交叉韧带断裂患者的足底压力数据分析, 实现智能辅助诊断。结合临床数据的实验结果表明, PressureConvLSTM模型对前交叉韧带断裂的辅助诊断, 能够达到95%的预测准确度; 与卷积神经网络等其他模型相比, 准确度得到大幅度提升。
