Md Fahim Sikder is currently pursuing his Ph.D. under the guidance of Professor Fredrik Heintz and Assistant Professor Daniel de Leng at the Reasoning and Learning (ReaL) Lab, IDA, Linköping University, Sweden. His research focuses on creating Generative Models for Time-Series and Fair Data Generation. Before this, Fahim served as a Lecturer in the Computer Science and Engineering department at the Institute of Science, Trade, and Technology (ISTT). He also took on the roles of Coordinator of the HEAP Programming Club and Coach of the ACM ICPC team at ISTT.
Fahim’s research interests include Artificial Intelligence, Generative Models, Trustworthy AI.
Md Fahim Sikder conducted several workshops and seminars, including a Workshop on Latex and a Week-long training course on Python (Beginning to Advance including Machine Learning). He participated in several National and International Contests. He achieved many titles, including “Champion at International Contest on Programming and System Development (ICPSD), 2014”, and “Champion at NASA SPACE APPS CHALLENGE 2016” in Rajshahi Region, Bangladesh.

The generation of high-quality, long-sequenced time-series data is essential due to its wide range of applications. In the past, standalone Recurrent and Convolutional Neural Network-based Generative Adversarial Networks (GAN) were used to synthesize time-series data. However, they are inadequate for generating long sequences of time-series data due to limitations in the architecture. Furthermore, GANs are well known for their training instability and mode collapse problem. To address this, we propose TransFusion, a diffusion, and transformers-based generative model to generate high-quality long-sequence time-series data. We have stretched the sequence length to 384, and generated high-quality synthetic data. Also, we introduce two evaluation metrics to evaluate the quality of the synthetic data as well as its predictive characteristics. We evaluate TransFusion with a wide variety of visual and empirical metrics, and TransFusion outperforms the previous state-of-the-art by a significant margin.
