Hello and welcome to my online home.

Thank you for the opportunity to introduce myself. This site is my personal blog where I write about topics that interest me and a little bit about myself :)

Studying and applying math has always been an important part of my life. I grew up in a family of engineers in the Soviet Union, which exposed me to math and science very early in life. Back then, Soviet math and engineering schools were the best in the world. As a kid, I went to a math school and later graduated from Odessa State University with a Master's degree in Applied Mathematics. My favorite subjects were Linear Algebra, Mathematical Optimization, and Cluster Analysis.

This naturally led to my current interest in artificial intelligence, especially in areas of neural networks and unsupervised learning. I like to share my passion for math and even taught math at the Russian School of Mathematics. My other interests include math, foreign languages, and optical illusions.

In this blog, I follow topics related to my professional activities in Artificial Intelligence, Data Analytics, and Data Visualization. I have always been fascinated by languages. As Charlemagne said, "To have a second language is to have a second soul". I am fluent in English, Russian, and Ukrainian. I also flirted with Italian and Spanish, although I am very far from being fluent. For me, a language is like an acquaintance who could become a friend as you get to know it better.

I love the San Francisco Bay Area which became my second home. I enjoy the warm "eternal spring" climate with no winter, but even more importantly, I admire the open, friendly people who come here from every corner of the Earth.
