Dr. Ching-Yung Lin is the IBM Chief Scientist, Graph Computing, and an IBM Distinguished Researcher. He is the founder and senior manager of the Network Science and Machine Intelligence Department in IBM T. J. Watson Research Center. He has been with IBM Research since 2000, after receiving his Ph.D. from Columbia University. Dr. Lin is also an Adjunct Associate/Full Professor in the Departments of Electrical Engineering and Computer Science, Columbia University since 2005. He was an Affiliate Assistant/Associate Professor in the University of Washington from 2003 to 2009, and an Adjunct Professor in New York University (NYU) in 2014.
His research interests are on fundamental research of machine learning, artificial intelligence, data mining, multimodality signal understanding, network science, brain analysis, and applied research on security, commerce, and collaboration. Lin was elevated to IEEE Fellow for "contributions to network science and multimedia security and retrieval" in Nov 2011. He was the first IEEE fellow cited for contribution to Network Science. Dr. Lin founded and leads the Linked Big Data direction in IBM Research. Since 2011, he has been leading a team of more than 40 Ph.D. researchers in worldwide IBM Research Labs (Watson, Almaden, Cambridge, Austin, India, China, Brazil, and Australia) and more than 20 professors and researchers in 10 universities and institutes (Northeastern, Northwestern, Columbia, Minnesota, Rutgers, CMU, New Mexico, USC, UC Berkeley, and Stanford Research Institute).
He is leading a big R&D project of “IBM System G,” which is dedicated to advance science, technology, and industry solutions based on cognitive networks and graph computing. He has been the Principal Investigator of many external funded (~$25M) projects: DARPA Anomaly Detection at Multiple Scales (ADAMS), DARPA Social Media in Strategic Communications (SMISC), ARL Social and Cognitive Network Academic Research Center (SCNARC), DHS Mobile Security, and several other projects with major global companies and worldwide governments, across the industries of Governments & Public Sector, Financial Services Sector, Aerospace Sector, Telecommunication Sector, Healthcare Sector, and Energy Sector. He is also leading IBM worldwide research on cognitive solutions for investment & commercial banks and insurance, especially in the areas of Fraud, Surveillance, Risk, Compliance, Anti-Money Laundering, Espionage, Sabotage, etc, and led to create the first cognitive security product in the financial industry — IBM Surveillance Insight for Financial Services.
His team focuses on all aspects of large-scale Graph Computing -- graph database, high performance and distributed computing infrastructure, graph analysis library, and graph visualization. The goal is to create innovative foundation to solve the biggest challenge of Big Data when data are dependent. These tools include different types of graph databases, which outperform traditional relational databases in many modern applications. Graph Middleware considers different ways of optimization on platforms and Software Defined Environment. Graph Analytics include topological analysis, graph matching, graph search, graph path & flow tools. Graph visualization provides foundations for static, large-scale, and dynamic visualization for data exploration, visual analytics, and navigation. His team has been providing software that tops the Supercomputer society’s Graph500 benchmark which achieved 38 billion graph traversal per second. Based on the graph computing foundation, on Machine Intelligence, his team has been making fundamental research on (1) Cognitive Networks, including large-scale machine reasoning Markovian & Bayesian networks, Deep Machine Learning tools, and Brain Network Analysis Tools; (2) Cognitive Analytics, including visual semantic & sentiment analysis and text emotion analysis; (3) Spatiotemporal Analytics, including moving objects indexing, retrieval, and optimization; and (4) Behavioral and Mobile Analytics, including anomaly detection (fraud, espionage, and sabotage), and various recommenders. These tools have been applied to 7 Industry Solutions: Enterprise Social Analytics Solution, Insider Threat Solution, Social Media Solution, Entertainment & Media Solution, Healthcare Solution, Home Care Solution, and Financial Services Solution. There are also more than 22 use cases on 5 Big Data categories: Data Exploration, 360 View, Security, Operation Analysis, and Data Warehouse. His team is consisted of researchers with backgrounds of Signal Processing, Network Science, Machine Learning, Information Retrieval, Natural Language Processing, High Performance Computing, Visualization, Economics, Database, etc.
He invented and created the SmallBlue system, an IBM production system for Enterprise Social Network Analysis, Expertise Search, and Knowledge Recommendation since 2008. SmallBlue helped IBM Corporation won the 1st place in 2012 Most Admirable Knowledge Enterprise (MAKE) Award in enterprise-wide collaboration knowledge-sharing environment. In May 2013, SmallBlue was selected by APQC, the World Leader in Knowledge Sharing Benchmarking and Practices, as the Industry Leader and Best Practice in Expertise Location. In October 2013, SmallBlue was recognized as having made $117M+ productivity contribution to IBM.
Dr. Lin’s innovative Cognitive Security system focuses on anomaly detection of behaviors and had the best performance in the program reviews. It has been used for insider threat detection such as espionage, sabotage, or fraud detection. Another system -- SMISC focuses on social media monitoring, forensics, and predictive analysis. Lin leads 9 universities on this direction, which alone includes 26 research projects on various aspects of social media analysis. Lin demonstrated both systems in Pentagon in May 2014 and attracted more than 200 audiences.
Ching-Yung is an author of 160+ publications and 23 awarded patents (Google Scholar: 8,000+ citations, hindex: 42, first-author paper citations: 3,500+). In 2010, IBM Exploratory Research Career Review selected Dr. Lin as one of the five researchers "mostly likely to have the greatest scientific impact for IBM and the world.”
He is teaching “Big Data Analytics” and “Advanced Big Data Analytics” graduate courses in Columbia University in the Fall and Spring semesters. In the course evaluations of the last 4 years, in total, 53% of the students rated Prof. Lin's overall teaching as 'excellent' and 28% rated 'very good'. In a 1-5 scale, the mean was 4.25 and the median was 5 (excellent). His classes attract more than 300 students per year, and the “Big Data Analytics” is the largest graduate class in the departments of Electrical Engineering and Computer Science.
