Dec 21, 2020 · Augmented Time Series (image by the author) SUMMARY. In this post, we introduced an application of Variational AutoEncoder for time-series analysis. We built a VAE based on LSTM cells that combines the raw signals with external categorical information and found that it can effectively impute missing intervals.
Define your dataset into dataset.py and put in output into the function get_dataset; Eventually change encoder and decoder inside VAE.py to fits your data ...

15.11.2021 · Recent work in synthetic data generation in the time-series domain has focused on the use of Generative Adversarial Networks. We propose a novel architecture for synthetically generating time-series data with the use of Variational Auto-Encoders (VAEs). The proposed architecture has several distinct properties: interpretability, ability to encode domain …
