Mahdi Zaman

I am an engineer with a rationally optimistic enterpreneurial mindset, experienced in robot vision, connectivity and transportation. Currently I do research on memory-efficient vision models and connected automated driving at CAVREL-UCF. I am seeking industry mentors and would love to work as an intern with you for Summer 2024. Please reach out to discuss ideas and projects that we can work on together.

I am driven by the curiosity to explore our abilities as a species. Engaging in the field of machine intelligence can yield useful insights in this pursuit. I spend most of my time in developing algorithms and systems aimed at robot vision and learning; both at the level of individual agent and within larger systems. In my spare time, I enjoy delving into concepts on evolution, fitness, neuroscience, psychology and spirituality, often through hands-on experiences. Occassionally, I share concise reflections on my thoughts and personal experiences through my blog.

Research & Projects

I build algorithms and systems for robots. My research projects have been wonderful opportunities to learn about robot perception, remote driving (both automated and humandriven), scaling vehicular communication and writing systems for specific applications. Currently I am working on the highlighted projects.

Perception & Control for Autonomous Vehicles

Working on improving scene understanding in machine vision to make better decisions.

Working on a novel multi-scale attention mechanism which currently achieves comparable performance on semantic segmentation with much lower computational cost than state-of-the-art models of similar size. Currently expanding the scope of the project to include classification, object detection and instance segmentation.

We present a novel neural network model to leverage local (from on-board sensors) and look-ahead (via V2X) perception for efficient steering maneuver. It empowers the host vehicle with enhanced safety and prior knowledge for navigating a wide range of road scenarios.

Infrastructure-assisted Tolling

An infrastructure-assisted transaction procedure is presented. Potential use-cases are: toll collection, road user charging, remote driving, automated valet parking etc. The application leverages high-speed communication via Cellular-V2X. Outcomes aim for development of SAE J3217 standard.

Scaling V2X

Vehicle-to-everything (V2X) communication enables vehicles to share their cognition and constitute a form of mass intelligence in partial or fully autonomous traffic environment to overcome the limitations of a single agent planning in a decentralized fashion. Specifically, our proposed methods enable the 3GPP C-V2X communication technology to handle thousands of vehicles in heavily congested environments.

Mahdi Razzaghpour, Rodolfo Valiente, Mahdi Zaman, Yaser P Fallah
IEEE Open Journal of Intelligent Transportation Systems, Vol. 4, pg 232-243, 2023
paper / arXiv / bibtex

We leverage Model-Based Communication (MBC) and propose a solution that enables cooperative control of vehicle platoons under non-ideal communication scenarios.

IEEE International Systems Conference (SysCon), 2022
paper / arXiv / bibtex

We model the inter-vehicle links in a platoon with a first-order Markov model to capture the prevalent temporal correlations for each link.

We propose a combination of control-aware communication and model-based communication. Our proposed solution reduces communication overhead by ~47% while maintaining nearly the same level of efficiency (less than 1% speed deviation) in cooperative adaptive cruise control.

We propose a modular architecture with separate subsystems for application and perception with a novel non-parametric Bayesian inference-based prediction method. We validate the architecture in conjunction with the prediction mechanism with real environment using Denso On-Board-Unit (OBU). The proposed system shows enhanced immunity to communication loss in V2X channel.
