Class Conditional Time Series Generation with Structured Noise Space GAN

no code implementations20 Dec 2023 Hamidreza Gholamrezaei, Alireza Koochali, Andreas Dengel, Sheraz Ahmed

This paper introduces Structured Noise Space GAN (SNS-GAN), a novel approach in the field of generative modeling specifically tailored for class-conditional generation in both image and time series data.

A Bayesian Generative Adversarial Network (GAN) to Generate Synthetic Time-Series Data, Application in Combined Sewer Flow Prediction

no code implementations31 Jan 2023 Amin E. Bakhshipour, Alireza Koochali, Ulrich Dittmer, Ali Haghighi, Sheraz Ahmad, Andreas Dengel

In this study, we developed a GAN model to generate synthetic time series to balance our limited recorded time series data and improve the accuracy of a data-driven model for combined sewer flow prediction.

Random Noise vs State-of-the-Art Probabilistic Forecasting Methods : A Case Study on CRPS-Sum Discrimination Ability

no code implementations21 Jan 2022 Alireza Koochali, Peter Schichtel, Andreas Dengel, Sheraz Ahmed

The recent developments in the machine learning domain have enabled the development of complex multivariate probabilistic forecasting models.

If You Like It, GAN It. Probabilistic Multivariate Times Series Forecast With GAN

1 code implementation3 May 2020 Alireza Koochali, Andreas Dengel, Sheraz Ahmed

The motivation of the framework is to either transform existing highly accurate point forecast models to their probabilistic counterparts or to train GANs stably by selecting the architecture of GAN's component carefully and efficiently.
