arXiv:2507.23615v2 Announce Type: replace Abstract: Data augmentation is becoming increasingly important across various areas of time series analysis, including forecasting, classification, and anomaly detection. We introduce the Latent Generative Temporal Augmentation (L-GTA) model, a generative approach based on a Variational Autoencoder with a Bi-LSTM backbone and temporal self-attention. The model learns a latent representation for each timestep and applies controlled perturbations such as jittering, magnitude warping, or drift. We define an equivariance objective to further encourage cons
The increasing demand for robust time series analysis in AI applications drives the continuous innovation in data augmentation techniques.
This development enhances the reliability and performance of AI models in critical domains like forecasting, classification, and anomaly detection across various time-series dependent industries.
The introduction of L-GTA offers a more sophisticated generative approach to time series data augmentation, potentially leading to more accurate and resilient AI models.
