MIR New developments and applications in Big Data

Continued working on Multiple Latent Components Clustering (MLCC). The collaboration with University of Angers aimed at extending the method to work with data from zero inflated negative binomial distribution and proving mathematical properties of MLCC and PEnalized SEmi-integrated Likelihood (PESEL) method. Furthermore, we use MLCC to extract significant features/information from huge breast cancer data set (1200 observations, 60000 variables).

Clustering in low-dimensional subspaces

In this project I started working on Multiple Latent Components Clustering (MLCC). I was responsible for formalizing its mathematical basis, maintaining and extending R package Varclust that implements the method. Moreover, I performed throughout simulation study to justify that MLCC is competitive with state-of-the-art variable clustering methods.

Interests

Apart from my work, I enjoy doing and watching various sports, especially basketball, athletics and swimming. Among basketball leagues I consider NBA to be most fascinating and my two favorite players are Russel Westbrook and Kevin Durant . As a former sprinter I am still amazed by Wayde van Niekerk’s world record. I love learning about history and society, here are some of my favorites books, channels and podcasts:

As for my other interests, I am keen on travelling (most beautiful city - Porto, Portugal, most astonishing view - Tatev, Armenia, best beach - Tangalle, Sri Lanka). In my free time I like visiting escape rooms and reading books . However, my most beloved activity is going to rock concerts.

I am also an avid fan of the MCU and a follower of Factfulness idea.
