Teaching Experience

Graduate Courses

Online Courses

• Introduction to Data Science (passed with distinction, 99.3%), on Coursera.com, June 2013.

This course covered a broad set of topics critical to practical data science: relational databases, MapReduce, NoSQL, statistical modeling, basic machine learning, and visualization, and a variety of algorithmic topics.

• Machine Learning on Coursera.com, Fall 2016
• Machine Learning Crash Course on ai.google, March 2018

Selected Course Projects

• Analyzing properties of a 0.5TB (a billion vertices) RDF graph using Pig/Hadoop on Amazon EC2. The goal of this project in Introduction to Data Science course on Coursera.com was to compute the histogram and walk on the graph as an introductory step to Pig and Amazon EC2.
• Casebook: implementing simplified post and photo features of Facebook. I used Cassandra as backend database and Python to distribute the load of initializing text search engine and face recognition (using OpenCV). I could load data of 140 users each having 1k posts and 100 photos in 2 minutes using 6 cores and 6 GB RAM on 5 machines.
• Queueing analysis and simulation of a VOIP system in three levels of details: Call, Voice spurt and Packet
