“…In social sciences, agent-based models simulate human behaviour, social networks, and economic systems [28]. In manufacturing and supply chain management, discrete event simulation models replicate production processes, logistics networks, and inventory systems [29]. These techniques generate synthetic data to analyse, make informed decisions, and evaluate policies in respective fields.…”

The use of high-fidelity synthetic data for data augmentation is an area of growing interest in data science. In this chapter, the concept of synthetic data is introduced, and different types of synthetic data are discussed in terms of their utility or fidelity. Approaches to synthetic data generation are presented and compared with computer modelling and simulation approaches, highlighting the unique benefits of high-fidelity synthetic data. One of the main applications of high-fidelity synthetic data is supporting the training and validation of machine learning algorithms, where it can provide a virtually unlimited amount of diverse and high-quality data to improve the accuracy and robustness of models. Furthermore, high-fidelity synthetic data can address missing data and biases due to under-sampling using techniques such as BayesBoost, as well as boost sample sizes in scenarios where the real data is based on a small sample. Another important application is generating virtual patient cohorts, such as digital twins, to estimate counterfactuals in silico trials, allowing for better prediction of treatment outcomes and personalised medicine. The chapter concludes by identifying areas for further research in the field, including developing more efficient and accurate synthetic data generation methods and exploring the ethical implications of using synthetic data.

Identifying Unstriped Bunches (USB) is a pivotal challenge in palm oil production, contributing to reduced mill efficiency. Existing manual detection methods are proven time-consuming and prone to inaccuracies. Therefore, we propose an innovative solution harnessing computer vision technology. Specifically, we leverage the Faster R-CNN (Region-based Convolution Neural Network), a robust object detection algorithm, and complement it with Progressive Growing Generative Adversarial Networks (PGGAN) for synthetic image generation. Nevertheless, a scarcity of authentic USB images may hinder the application of Faster R-CNN. Herein, PGGAN is assumed to be pivotal in generating synthetic images of Empty Fruit Bunches (EFB) and USB. Our approach pairs synthetic images with authentic ones to train the Faster R-CNN. The VGG16 feature generator serves as the architectural backbone, fostering enhanced learning. According to our experimental results, USB detectors that were trained solely with authentic images resulted in an accuracy of 77.1%, which highlights the potential of this methodology. However, employing solely synthetic images leads to a slightly reduced accuracy of 75.3%. Strikingly, the fusion of authentic and synthetic images in a balanced ratio of 1:1 fuels a remarkable accuracy surge to 87.9%, signifying a 10.1% improvement. This innovative amalgamation underscores the potential of synthetic data augmentation in refining detection systems. By amalgamating authentic and synthetic data, we unlock a novel dimension of accuracy in USB detection, which was previously unattainable. This contribution holds significant implications for the industry, ensuring further exploration into advanced data synthesis techniques and refining detection models.
