6 lenin mookiah Research Assistant at Tennessee Technological University 10 people have recommended lenin "Lenin is a proactive, highly self-disciplined and tireless contributor who would make a great addition to any team. As Research Intern, Lenin joined my team from Jan 2013 and focused on the research of web analytics data. From the first day of his intern journey, Lenin has already demonstrated his passion, abilities and cooperation with other team guys. Lenin has a strong Data Mining fundamental knowledge and skills. During his internship, he focused on the research of data anomaly detection. He proposed a new method which can be applied for the time-series data anomaly detection independently, and he was also main contributor of a patent application based on his proposal. Lenin has also strong programming and hands-on abilities, he completed his all assignments independently, for example, to verify his proposal of anomaly detection, he setup the development envelopment based on OpenTSDB/HBase, and completed all algorithm implementation. He also did a great Data Visualization implementation to illustrate the anomaly detection in web front-end. Most important, Lenin is full ideas and has an eye for data analysis, and he worked very closely with team. he has strong willing to share his knowledge, participate the technical discussion within team. Since he has strong data mining skills, team got many advice/suggestion from Lenin about sentimental analysis, data dimension reduction and so on. Throughout the whole internship, Lenin completed his assignments on time and be always beyond my expectation. I would highly recommend him for any position."
