Direct PhD Student

Dept. of CS & IE, YunTech

Yunlin, Taiwan

I am Muhammad Junaid Ali Asif Raja, a Machine Learning Researcher at the National Yunlin University of Science and Technology (YunTech), Taiwan, advised by Prof. Chuan-Yu Chang and mentored by Prof. Muhammad Asif Zahoor Raja.

I am a Direct PhD student, having transitioned from the Master’s program in September 2025. I hold a Bachelor’s degree in Electrical Engineering from SEECS, NUST, Islamabad, where I was advised by Prof. Faisal Shafait and Prof. Adnan Ul-Hasan, and affiliated with the TUKL-DLL Lab, NCAI.

My research develops intelligent neural surrogates, primarily data-driven autoregressive neural emulators, for fractional-order nonlinear dynamical systems. My thesis focuses on designing intelligent neural surrogate networks for nonlinear dynamical reconstruction of neuronal systems. I also work on fractional-calculus-inspired deep learning optimization algorithms for accelerated large language model training.

I have authored 27 publications across 23 WoS Core Collection indexed journals, including Chaos, Solitons & Fractals, Water Research, IEEE Transactions on Computational Biology and Bioinformatics, Nonlinear Dynamics, and Engineering Applications of Artificial Intelligence. I am a member of the Phi Tau Phi Scholastic Honor Society (top 2% of graduate master’s students).

In aquatic ecosystems, the triadic relationship among phytoplankton, zooplankton, and their piscine predators constitutes a delicately balanced ecological continuum where nutrient cycling, toxin transfer, and spatial refugia collectively dictate population persistence. In this paper, the fractional-order dynamics of Nekton-Plankton Coupled systems are analyzed using intelligent computing driven autoregressive exogenous artificial neural networks trained by a hybrid second-order Bayesian Regularized Levenberg-Marquardt optimization algorithm, achieving remarkably low errors in the ranges of 10-04 to 10-12.

The incredible synergy between monoclonal antibodies and interferons in cancer chemotherapy signifies a stride forward in our battle against this inexorable disease. This study develops a precise and reliable application of numerical as well as artificial intelligence-based treatment methodology via predictive supervised exogenous networks for calculable understanding of the movement of the immune response to treatment such as timing, dosing and forecasting therapy retorts. The framework demonstrates impressive performance and accuracy, achieving a mean square error between 10-11 and 10-8 through iterative refinement.

In this study, nonlinear autoregressive exogenous neural network coupled with Levenberg-Marquardt is efficaciously selected to model the fractional-order toxin-plankton system asserting the phytoplankton and zooplankton dynamics in aquatic environments under the influence of environmental toxins. The fractional differential ecological system incorporates density population of phytoplankton, zooplankton, and environmental toxins exacted by fractional Adams multistep predictor-corrector method. Rigorous analysis on single-step and multistep ahead predictors with error of order 10-5 further highlights the efficacy of the employed neurocomputing design.
