Abstract
This paper describes the development and validation of an artificial neural network based on the YOLOv4 object detection algorithm for recognizing objects in a custom dataset.
The authors first provide an overview of the YOLOv4 algorithm, which is a state-of-the-art object detection model that uses a convolutional neural network to simultaneously predict bounding boxes and class probabilities. They then discuss the process of creating a custom dataset for their experiments, including data collection, annotation, and preprocessing.
Next, the authors detail the architecture and training of their YOLOv4-based neural network model. Key aspects include:
Utilizing the YOLOv4 backbone with customized head layers for the target dataset
Employing data augmentation techniques to improve model generalization
Optimizing hyperparameters such as learning rate, batch size, and number of training epochs
The performance of the trained model is then evaluated on the custom dataset using standard metrics like precision, recall, and F1-score. The results demonstrate the effectiveness of the YOLOv4-based approach in accurately detecting and recognizing the objects of interest.
Finally, the authors discuss the implications of their work, such as the potential for deploying the model in real-world applications, and outline future research directions.
Stats
The custom dataset used in this study contains 10,000 images with 20 different object classes.
The YOLOv4-based neural network achieved an average precision of 92.5% and an average F1-score of 90.2% on the test set.
