All Eyez On Data

Harutyun Khachatryan

I have PhD in Theoretical and Mathematical Physics. I am co-author or author of about 20 scientific papers. My second specialization is Data Science along with Big Data. I have also solid experience in Big Data tools like: Apache Spark, Apache Solr, Kafka, HBase, HDFS, Hive and others.

I used numerous machine learning algorithms during my career like: principal component analysis, self-organized maps, k-means, k-nearest neighbours and also linear models like simple linear regression.

I developed an algorithm to predict time series data using linear regression and Holt-Winters models. In my professional career in Physics (Astrophysics) I calculated tidal perturbations of Lares/Lageos satellite, constructed long range Hubble diagram for gamma-ray bursts.
