Tom Kral

IT Trainee & Big Data Enthusiast


I believe that for every analytical problem, there are results to be gained. Every outcome tells us something that we can learn from. It's my ambition to analyse problems and/or questions and come to a solution in a structured manner. Data analyses can either change or confirm the way we see things. I aspire to guide myself and others to making better decisions faster. By doing studies, traineeships and my own projects I want to specialize in the fields of Big Data and Machine Learning to reach these goals.

GEO Registration Employee

The RvO encourages entrepreneurs in sustainable, agrarian, innovative and international business. It helps with grants, finding business partners, know-how and compliance with laws. I'm part of the GEO team that investigates if the borders of Dutch farmlands are in accordance with regulations. I review the disagreements agrarians bring to our attention and check if our border needs to be changed or not. I use aerial photographs for this task. I also engage in conversations over the phone if the disagreements persist to provide explanations regarding the regulations. This way, my colleagues and I want to give Dutch agrarians a better understanding about the rules and a chance for them to be heard.

Detecting birds with the Raspberry Pi

Python, SQL, Raspberry Pi

One of my hobbies is bird watching, but don't always have the time. With a Raspberry Pi and camera, I created a pipeline to detect birds that visit the feeder on my balcony. This information gives me more insight in the lives of urban birds.

Does Sentiment, Expressed by Tweets, Have an Effect on Vaccination Coverage With COVID-19 Vaccinations?

R, Sentiment Analysis, Linear Regression

This was my final project at the LOI. During my studies, the pandemic became a worldwide dilemma. Vaccinating is the answer, but opinions about this approach differ. I asked myself if these sentiments can be measured, and if they have an effect on the willingness of people to receive an injection.
