Yong Sheng’s Summary

I am an engineer with 15+ years of experiences in the information industry, in both engineering and research. I devote myself to building world-class information systems that matter to people. To be more specific, I like to dig into a tremendous amount of data collected all over the world, in order to discover interesting and useful information, like causal relationships, patterns, trends, and so on. These discoveries may change people's minds.

Yong Sheng’s Specialties:

large scale distributed systems, data mining, machine learning, VOIP, telephony

Yong Sheng’s Education

  PhD , Engineering Science , 2001 — 2006

  During the 5-year pursuing a doctoral degree at Dartmouth, I worked on a new kind of information retrieval system, what we call Process Query System (PQS). "Process" is a high-level abstract of most real-world activities that produce observable time-series. PQS provides methods to query processes from time-series data using statistical models, just like people query database records using an SQL "select" statement.
  
  We successfully prototyped PQS to different application domains:
  - network security, for example, intrusion detection systems;
  - physical object tracking, consider how radar tracks aircrafts;
  - social network analysis, how people connects to each other;
  - sensor networks;
  - automatic computing.
  
  Through this research project I developed expertises for statistical models and data mining, specifically:
  - discrete time series analysis;
  - Markov models, Bayesian networks, Kalman filters, and their applications in data mining;
