Speech of Professor Hari on Autonomous Navigation

On 2nd of June 2023 Professor K. V. S. Hari, from Department of ECE, Indian Institute of Science, Bangalore, presented his research on Experiments in Autonomous Navigation for Unstructured Environments. The event took place at the School of Electrical and Computer Engineering of the National Technical University of Athens. The presentation was followed by a very interesting conversation considering the future of the autonomous navigation and potentional uses. Our Research Team and all the attendees would like to thank and congratulate Professor Hari for his interesting speech and we are looking forward to continuing this interaction in the future. An abstract of his speech and information about the speaker follow below:

ABSTRACT: The emergence of autonomous navigation systems have spurred many innovations in the design of sensing, computing, communication and control systems. The design of autonomous navigation systems in unstructured environments is a challenging problem. For example, in an opencast or open-pit coal mine, large vehicles are driven on muddy roads with no lanes and roadside markers. Such environments pose a unique challenge to the design of autonomous systems. Similarly, urban environments where there is heavy traffic congestion with a large variety of vehicles and associated varied user behavior pose a challenge to designing autonomous navigation systems. In this talk, we will present two case studies. The first case study presents the design of a forward collision avoidance system for large vehicles using only a single webcam. This work was supported by VOLVO. The second case study presents the design of a sensing system to collect data for Indian road traffic and apply deep learning tools for detecting vehicles and predicting their trajectories. This work is supported by WIPRO.

ABOUT THE SPEAKER: K V S Hari is a Professor in the Department of ECE, Indian Institute of Science, Bangalore. He holds a PhD (Systems Science) from U C San Diego, an MTech (Radar and Communication Engineering) from IIT Delhi and a B.E (ECE) from Osmania University College of Engineering, He has been a visiting faculty at Stanford University and Affiliate Professor at KTH- Royal Institute of Technology, Stockholm.

Paper by ECE-NTUA Ph.D. Candidate V. Alimisis, Diploma Students A. Kamperi and N. P. Eleftheriou and Prof. P. P. Sotiriadis received the Best Runner-Up PhD Symposium Paper Award in the Springer FAIEMA 2023 Conference

We are pleased to announce that the paper entitled "A Low-Power Analog Bell-shaped Classifier based on Parallel-connected Gaussian function circuits" received the Best Runner-Up PhD Symposium Paper Award in the Springer 1st International Conference on Frontiers of Artificial Intelligence, Ethics, and Multidisciplinary Applications; 25th - 26th September 2023, Athens, Greece.

The Award-Winning paper was co-authored by Vassilis Alimisis (Ph.D candidate, ECE-NTUA), Argyro Kamperi (Diploma Student, ECE-NTUA), Nikolaos P. Eleftheriou (Diploma Student, ECE-NTUA), and Paul P. Sotiriadis (Professor, ECE-NTUA, Fellow IEEE).

ABSTRACT: In this study, a novel approach is presented for developing ultra-low power analog classifiers capable of effectively handling multiple input features while maintaining high levels of accuracy and minimizing power consumption. The proposed methodology is built upon a Voting model that leverages Gaussian likelihood functions. To evaluate the performance of the proposed methodology, a comparison is conducted against the widely used analog Bell-shaped classifiers. Real-life breast cancer dataset is employed for this comparison. The models are trained and the results are processed using the Python programming language. The hardware design and result processing utilize Cadence IC Suite, implementing the TSMC 90 nm CMOS process technology.
