CS Colloq: Amarjeet Singh

Talk Title: Application driven research in sensing and mobile computingSpeaker: Prof. Amarjeet SinghHost: Prof. Gaurav SukhatmeAbstract: Recent advancements in sensing technologies and mobile proliferation have significantly impacted several applied domains including environmental sensing and rural technology respectively. In sensing domain, applications that exhibit complex dynamics across both space and time and that can only be partially observed are of particular interest. In rural technology, primary focus is on applications that are user friendly even for an illiterate person. For both environmental sensing and rural technology, there exists a problem of constrained resources. Further, lack of prior use of advanced technology in both the domains necessitates that for high fidelity understanding of such environments an iterative approach wherein real world deployment experiences in application domain should guide both the advancements in systems as well as deployment methodology.In this talk, I will first present our real world deployment experiences (using Networked Info Mechanical System – NIMS, developed at UCLA) in several critical environmental sensing applications including monitoring pollution in rivers and algae growth in lakes.
Large spatial expanse of such applications, together with limited available resources (sensing time or battery capacity) for mobile agents motivated our further research in performing efficient path planning for these mobile agents. I will present novel approximation algorithms for solving this NP-hard problem of path planning for mobile agents in such complex environments. In particular, we used Gaussian Process modeling to accurately represent the dynamics we observed in our real world deployments. We exploit several machine learning concepts to provide strong theoretical guarantees for the proposed algorithms. Several field experiments were performed, in addition to using multiple real world sensing datasets, to validate the effectiveness of the proposed algorithms for real world sensing applications.I will then move from mobile sensing for environmental applications to application driven research using mobile computing for addressing several challenges in socially responsive applications, particularly in the context of developing countries. I will first present the contextual difference between challenges in developing and developed countries for applications in mobile computing. Motivated by India specific contexts, I will then present some early stage work in two specific application areas of mobile computing – healthcare and GPS-less localization.Bio:Amarjeet Singh is currently an Asst.
