Kaggle Playground Series, August 2022: What I learned

I participated in this month’s beginner’s challenge on a simulated dataset that Kaggle releases every month. In the August 2022 challenge we are given simulated data from a fictional product test series and given the measured data, the task is to predict whether the product will fail or not in each case. In this post…… Continue reading Kaggle Playground Series, August 2022: What I learned

How is Data Science different from Machine Learning?

I have been working in a “Data Science” consulting team for 8 months now. Before that I got a Master’s degree in Computer Science with a machine learning specialization. So I could argue that I have seen both sides of the coin here and I have noticed some differences. Disclaimer: You will have trouble finding…… Continue reading How is Data Science different from Machine Learning?

How to build a Decision Tree for Classification with Python

As promised in my July 2022 Machine Learning Study Plans, here is content on decision trees. Specifically, let’s talk about how you can build a trained decision tree for a classification problem with the Python library Scikit-Learn. I will also address what steps you need to take before using the example dataset in terms of…… Continue reading How to build a Decision Tree for Classification with Python

One Hot Encoding – How to deal with categorical data in Machine Learning

Many models in machine learning don’t work with categorical data. So what do we do in that case? Of course you can always just remove them, but you would lose a lot of valuable information. So in this post, I share how you can use one hot encoding to make that information usable. I stumbled…… Continue reading One Hot Encoding – How to deal with categorical data in Machine Learning

Looking back on June 2022: Wrapping up work projects and reviving this blog

It’s always amazing how you think your life is incredibly boring until you write a wrap-up like this post and realize that stuff actually happened!! This month, “stuff” included a mini vacation (or workation?), a “first” at work (I work as a Data Science Consultant, check this post if you want to know what that…… Continue reading Looking back on June 2022: Wrapping up work projects and reviving this blog

Are Decision Trees the Siblings of Neural Networks? – Interesting research

I recently stumbled upon a research paper about decision trees that made me feel interested in decision trees for the first time in my life. Let me tell you why. My fascination with Neural Networks During my master’s degree (2020-2021) in Computer Science I developed a fascination for neural networks. But not because of their…… Continue reading Are Decision Trees the Siblings of Neural Networks? – Interesting research
