Green Coffee Beans Classification Using Attention-Based Features and Knowledge Transfer

In recent years, people’s need for coffee beans has skyrocketed, which results in automatic coffee beans quality recognition being highlighted by researchers. In this study, a Convolutional Neural Networks-based method which has the advantage of having high local feature extraction performance was presented. The experimental results show that the proposed method could be effectively utilized to perform green coffee beans recognition it achieved an F1-score of about 97%.
