Adaptive K-Fold Siamese Neural Network Classifier for Automatic Seatbelt Monitoring

A seatbelt is an essential aspect of safety in road traffic accidents. Although most traffic regulations enforce drivers and passengers to wear and fasten the seatbelt manually, AI-based techniques have been introduced for monitoring to improve safety standards. In this study, a new approach is proposed to address the monitoring problem of seatbelts. Deep learning (DL) classification based on adaptive Siamese Neural Network (SNN) has been developed utilizing the K-fold method for feature verification. The proposed adaptive K-Fold-based SNN approach utilizes a binary seatbelt dataset, with positive and negative classes, to verify the status of the seatbelt. The network involves sharing a convolutional feature extractor, followed by a distinct-based similarity function. To enhance model reliability, 5-fold cross validation is applied (k = 5), splitting the dataset into 5 subsets, where the model is trained on four sets and validated on the fifth one. The model was trained using binary cross entropy loss, Adam optimization, and performance metrics such as accuracy, precision, recall, and F1 score. The seatbelt dataset is basically designed for object detection models. In this work, we used a dataset in the verification model and achieved high-performance metrics. The model is implemented using a Python-based Jupyter Notebook 7.5.1. It achieved a high performance in seatbelt verification with an average Accuracy = 0.9989, average Precision = 0.9988, average Recall = 0.9990, and average F1 Score = 0.9989. The proposed adaptive K-Fold SNN model can ensure reliability and reduce the risk of over fitting.
