The synthetic generation of data using artificial intelligence has emerged as a strategic response to data scarcity, confidentiality, and imbalance. This study explores whether a Generative Adversarial Network (GAN) can generate synthetic daily sales data for Chilean SMEs that preserves statistical distributions and temporal patterns for sales forecasting. The methodology trains a tailored GAN on anonymized datasets and evaluates the generated data using distributional similarity, Dynamic Time Warping (DTW), and regression-based predictive performance. Results show that combining real and synthetic data improves forecasting accuracy while maintaining privacy.

摘要

The synthetic generation of data using artificial intelligence has emerged as a strategic response to data scarcity, confidentiality, and imbalance. This study explores whether a Generative Adversarial Network (GAN) can generate synthetic daily sales data for Chilean SMEs that preserves statistical distributions and temporal patterns for sales forecasting. The methodology trains a tailored GAN on anonymized datasets and evaluates the generated data using distributional similarity, Dynamic Time Warping (DTW), and regression-based predictive performance. Results show that combining real and synthetic data improves forecasting accuracy while maintaining privacy. The study contributes to AI-driven data augmentation by adapting GANs to a local context with limited data availability, with a systematic evaluation framework, and by demonstrating the potential of synthetic datasets to support inclusive financing and digital transformation in underrepresented Latin American ecosystems.
