Toplam 166 atıf DOI
The main product of grapevines is grapes that are consumed fresh or processed. In addition, grapevine leaves are harvested once a year as a by-product. The species of grapevine leaves are important in terms of price and taste. In this study, deep learning-based classification is conducted by using images of grapevine leaves. For this purpose, images of 500 vine leaves belonging to 5 species were taken with a special self-illuminating system. Later, this number was increased to 2500 with data augmentation methods. The classification was conducted with a state-of-art CNN model fine-tuned MobileNetv2. As the second approach, features were extracted from pre-trained MobileNetv2′s Logits layer and classification was made using various SVM kernels. As the third approach, 1000 features extracted from MobileNetv2′s Logits layer were selected by the Chi-Squares method and reduced to 250. Then, classification was made with various SVM kernels using the selected features. The most successful method was obtained by extracting features from the Logits layer and reducing the feature with the Chi-Squares method. The most successful SVM kernel was Cubic. The classification success of the system has been determined as 97.60%. It was observed that feature selection increased the classification success although the number of features used in classification decreased.

Effective waste management requires the correct categorization of recyclables. It is possible to classify organic waste and recyclable waste using machine learning techniques. Accurately sorting waste is important for improving recycling processes, however separating organic waste from recyclables remains a challenge. This study aimed to provide the importance of machine learning in the field of waste management and automate classification of solid waste. We compared the accuracy of three machine learning classifiers based on the Chi2 feature selection method. Feature extraction was performed using the InceptionV3 deep convolutional neural network. The training of three machine-learning classifiers was performed using the extracted features. Based on a labeled waste classification image dataset, the performance of the classifiers was evaluated. Despite using any of the feature’s selections, SVM attained an accuracy of 96.3%, Decision Tree an accuracy of 85.8%, and KNN an accuracy of 94.9%. However, with feature selection using Chi2, a slight decrease in accuracy was observed. We demonstrate that machine learning algorithms can classify solid household waste with an automated model. Using the findings from this study, we can create a system that achieves optimal efficiency in terms of waste classification and management. This system can then be implemented in the real world.
