초록

Traditional manual identification of crop leaf diseases is challenging. Owing to the limitations in manpowerand resources, it is challenging to explore crop diseases on a large scale. The emergence of artificial intelligencetechnologies, particularly the extensive application of deep learning technologies, is expected to overcome thesechallenges and greatly improve the accuracy and efficiency of crop disease identification. Crop leaf diseaseidentification models have been designed and trained using large-scale training data, enabling them to predictdifferent categories of diseases from unlabeled crop leaves. However, these models, which possess strongfeature representation capabilities, require substantial training data, and there is often a shortage of such datasetsin practical farming scenarios. To address this issue and improve the feature learning abilities of models, thisstudy proposes a deep transfer learning adaptation strategy. The novel proposed method aims to transfer theweights and parameters from pre-trained models in similar large-scale training datasets, such as ImageNet. ImageNet pre-trained weights are adopted and fine-tuned with the features of crop leaf diseases to improveprediction ability. In this study, we collected 16,060 crop leaf disease images, spanning 12 categories, fortraining. The experimental results demonstrate that an impressive accuracy of 98% is achieved using theproposed method on the transferred ResNet-50 model, thereby confirming the effectiveness of our transferlearning approach.

Abstract

Traditional manual identification of crop leaf diseases is challenging. Owing to the limitations in manpowerand resources, it is challenging to explore crop diseases on a large scale. The emergence of artificial intelligencetechnologies, particularly the extensive application of deep learning technologies, is expected to overcome thesechallenges and greatly improve the accuracy and efficiency of crop disease identification. Crop leaf diseaseidentification models have been designed and trained using large-scale training data, enabling them to predictdifferent categories of diseases from unlabeled crop leaves. However, these models, which possess strongfeature representation capabilities, require substantial training data, and there is often a shortage of such datasetsin practical farming scenarios. To address this issue and improve the feature learning abilities of models, thisstudy proposes a deep transfer learning adaptation strategy. The novel proposed method aims to transfer theweights and parameters from pre-trained models in similar large-scale training datasets, such as ImageNet. ImageNet pre-trained weights are adopted and fine-tuned with the features of crop leaf diseases to improveprediction ability.
