Rajarathnam Balakrishnan

Hey, I completed my Master of Engineering (M Eng) from University of California - Berkeley, in Industrial Engineering and Operations Research.

After the Masters program, I completed an year of Research Internship under the SCET, UC Berkeley.

I’ve worked on projects and research papers ranging from Optimization to Deep Learning in AI. I’m curious to explore Machine Learning and Artificial Intelligence Research Areas.

Pedestrian intention recognition is very important to develop robust and safe autonomous driving (AD) and advanced driver assistance systems (ADAS) functionalities for urban driving. In this work, we develop an end-to-end pedestrian intention framework that performs well on day- and night- time scenarios. Our framework relies on objection detection bounding boxes combined with skeletal features of human pose. We study early, late, and combined (early and late) fusion mechanisms to exploit the skeletal features and reduce false positives as well to improve the intention prediction performance. The early fusion mechanism results in AP of 0.89 and precision/recall of 0.79/0.89 for pedestrian intention classification. Furthermore, we propose three new metrics to properly evaluate the pedestrian intention systems. Under these new evaluation metrics for the intention prediction, the proposed end-to-end network offers accurate pedestrian intention up to half a second ahead of the actual risky maneuver.

Teams must be formed for all kinds of projects and purposes. Team formation is a key activity for innovation, entrepreneurship, class projects, and industry initiatives. Our experience with entrepreneurship and innovation has shown that a project’s results are highly dependent on the quality of team formation. In real life situations, team building is also time consuming. In this work we are developing a method and approach to form teams using algorithms. To do this, we develop a taxonomy for how teams are formed. We consider the key factors for team formation, identify measures for team effectiveness, as well as synthesize the framework with natural team formation processes. More importantly, we are proposing a generalized framework for algorithm based team formation. We provide sample algorithms with this framework to demonstrate its use in practical situations. The work of this paper also informs future characterization of the models developed here, which includes trade-offs for factors including optimality of team effectiveness, computation time, and policy considerations.
