Long words name little things.
All big things have little names,
Such as life and death, peace and war,
Or dawn, day, night, hope, love, home.
Learn to use little words in a big way.
It is hard to do, but they say what you mean.
When you don't know what you mean,
Use big words: That often fools little people.

Czech & Slovak ACM chapter of the IT SPY "best IT Master thesis of the year" competition - shortlisted
   My Master thesis "Robust visual heart rate estimation" was shortlisted in the Czech & Slovak ACM chapter of IT SPY.
   IT SPY is an elite IT competition evaluating the diploma theses of university students.
   Every year, dozens of ambassadors look for the very best of all successfully defended diploma projects. The competition is made up of 1,900 diploma theses drawn up at the IT faculties of Czech and Slovak universities. Joint decision is then made under the auspices of the oldest professional IT organisation ACM (Czech & Slovakia Chapter) on those which will be chosen to compete in the final.

Jun 2016 - Jul 2016
IJCAI 2016 Angry Birds AI Competition 3rd place
   The task of the Angry Birds AI Competition is to develop an intelligent agent that is able to play the Angry Birds game autonomously and without a human intervention [aibirds.org]. The agents are tested on a variety of levels.
   The team consisted of three students of the Faculty of Information Technology, CTU Prague. The agent used a meta-strategy to select a playing strategy and a local optimization techniques to play the selected move. The competition included teams from universities around the world including Great Britain, Germany, Italy, Austria, China, France, South Korea, Australia and India.

   The task of the competition was to develop a genetic algorithm that would solve the minimum vertex cover problem on a given graph with the least vertices count. The competition is held on an year basis. There were 50 participants in the competition.

Memberships: Feb 2016 - Present, Junior Research Fellow
Center for Machine Perception FEL CTU
   An approach of visual language identification was developed under the supervision of Jan Čech and Jiří Matas and published at the SCIA 2017 conference. Currently the photoplethysmographic signal properties are inspected.

Jun 2014 - Jul 2016, Junior Research Fellow
Data Laboratory FIT CTU
   Various tasks that concerned the robotic dairy farms optimization were accomplished. The most complex one - a real-time simulation of a dairy barn using 2D barn map that modeled interactions of cows and various robots - was finished and delivered to the Lely Inovation Department as a functional product.

Feb 2015 - Jul 2016, Data Scientist Trainee
Lely Inovation Department
   A close cooperation with the Lely Inovation Department was held. The cooperation included a stay at the company's headquarters in Netherlands. During the stay, the workflow of the dairy barns data gathering and processing was taught.

Jul 2016 - Sep 2017, Xenofil game
Producer & Lead programmer
   In 2016 an independent game developer studio Wonderful Tree Studio s.r.o. was found by me and a friend of mine from Charles University in Prague. In September 2017, the studio published a game "Xenofil" for mobile platforms (iOS and Android) that introduces a unique new game mechanism UN-match and through a hand drawn tale addresses issues as xenophobia, racism, and gender inequity.
   Press coverage (in Czech): Czech game Xenofil raises scary reactions, Czech students created a mobile game that should help to fight the xenophobia, A new Czech game that addresses the migration

Sep 2002 - Jun 2003, MS OFFICE 2000 interactively (in Czech)
   Microsoft (MS) Office 2000 interactively is a learning software that introduces MS Word and MS Excel to a user in an interactive way. The user builds his or her skill by completing specially designed tasks in a closed learning environment. The difficulty level of the consecutive tasks increases slowly so in the end the user is capable of solving quite complex assignments. The software was created in the Flash MX with using Action Script during the second year of my high school studies under the supervision of my teachers Robert Tišer and Zdeňek Novotný.
