I'm a Ph.D. student in the Department of Computer Science at North Carolina State University. My advisor is Dr. Tim Menzies. Previously a software engineer intern at Lexisnexis Risk Solutions in Solution and Architecture Team and before that a Software Engineer at Samsung Mobile working in Memory & File System. My Resume.
This summer I am a Research Intern at Microsoft, Redmond.
As a part of my Ph.D., I am exploring ways to easily optimize non-functional properties (e.g. runtime, latency etc.) of highly configurable systems. Techniques like spectral learning and rank based learning is used to learn features of the configurations.
This is a joint project with my colleague, Chin-Jung Hsu. We wanted to develop fast searching techniques, which are efficient, effective and robust, to find the best configuration in the cloud. The methods proposed uses low-level performance metrics to predict resource requirements which can be then used to eliminate `less promising' configurations and hence searches only the spotlight region of the configuration space.
This is a joint project with my colleague, Jianfeng Chen. We wanted to develop fast searching techniques, which can be used to optimize problems rather quickly. We have tried the searchers on various problems. This has resulted in few publications.
At LexisNexis, I worked on the developing a python package, which can be used to import (sampled) data stored in HPCC cluster to a local machine. This was achieved using the web services exposed by the HPCC platform. The prototype is available here.
During Summer'16, I worked on developing machine learning plugins for Data Science Portal (DSP). DSP is a graphical toolkit, which runs HPCC under the hood. It relieves the users to learn or optimize ECL code and provides a graphical interface to generate machine learning pipelines. The code required to adapt the code to DSP required careful porting of the existing ML library. The pull request is available here. The work was presented at the HPCC summit as a part of the HPCC poster competition. The copy of the poster is available here.
Since, HPCC ML suite was in its nascent stage, I had an opportunity to develop the testing suite for the ML suite. It was particularly a very interesting because I got to learn how to use the macros and functionmacros, which are indeed very powerful. The pull request can be found here.
A naive stab at extending a framework, JMOO - originally developed by Joe Krall . The newer and extended version is called Storm. The newer version has new algorithms like MOEA/D, NSGA-III along with various other performance measures.
