Pseudo CNN: An Updated CNN Based Semi Supervised Learning Model for Leaf Disease Detection
摘要
Traditional supervised learning approaches require large, labeled datasets, which can be expensive and time-consuming to obtain. Semi-supervised learning (SSL) approaches, such as soft labelling and pseudo-labelling, have drawn a lot of interest to overcome this difficulty. This study investigates how to combine these methods to improve leaf disease prediction models’ accuracy while reducing their dependency on labelled data. While pseudo-labelling iteratively generates labels for unlabelled samples using reliable model predictions, soft labelling employs uncertainty information to apply probabilistic labels to unlabelled data. Combining these techniques in a semi-supervised framework enhances the model’s robustness and generalization in practical situations. Our approach’s promise for real-world agricultural applications is demonstrated by experimental results that indicate it performs better than fully supervised techniques with limited labelled data. This proposal helps to dispense confidence to the unlabeled data using class probabilities and high confidence predictions are used to redevelop the model gradually. Experimental results demonstrate that the proposed model achieves superior performance compared to fully supervised methods, achieving an accuracy of 96.4% with a significant reduction in labeling effort.
