Abstract

Abstract: The identification of Chinese herbal medicines (CHMs) is directly related to their safety and efficacy. However, the limited number of professionals fails to meet the demand of the vast CHMs market. To make the CHMs identification more convenient and accurate, this study aimed at assessing the feasibility of the automated machine learning (AutoML) technology in CHMs image recognition. Instead of a handcrafted neural network experimental models built on AutoML platform were presented. A dataset of 31, 460 images consisting of 315 categories of commonly-used CHMs was built for the model creation. Furthermore, the Huawei ModelArts model was compared with a model built on the Baidu EasyDL platform using the same dataset. Three professionals were also invited to recognize images of 315 categories of CHMs. During the model evaluation, high accuracies of 99.2% and 98.4% were achieved by ModelArts and EasyDL, respectively. In the held-out tests, the accuracies of ModelArts and EasyDL models were 91.2% and 91.85%, respectively. Both models performed very well individually and no statistically significant difference was found in model performance between them. However, the model-training time was only approximately 41 min on ModelArts platform but 118 min on EasyDL. The mean accuracy of the manual recognition for 315 CHMs was 97.46 ± 1.58%. Results revealed that AutoML technology is a fast and simple approach and has great practical potential in the field of CHMs image recognition. Since the Huawei ModelArts platform requires less training time, we recommend it as a priority.
