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……
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……
Machine Learning Study Plan for July 2022
Have you ever been totally motivated and started a course? Or bought a book? But then you never finished them and just felt bored by them and then felt bad because you didn’t finish it? Yeah, me too. This month I’m trying a different approach by setting more specific goals oriented by things that excite……
5 Reasons why I love Machine Learning
Many people in tech wonder which direction to go into: should they do machine learning, should they learn about cyber security or stick to web development? Personally I decided on machine learning and in this post I’ll take apart my reasons for why – other than “It’s just interesting”, which honestly is what comes to……
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……
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……
5 Tips for Studying Math at University Level
No matter if you have an exam looming or you just want to improve your math knowledge for your job or as a hobby, we all come to a point where we get overwhelmed by math and it just doesn’t make any sense and maybe we even want to quit. Here are my tips that……
What is validation data used for? – Machine Learning Basics
You have probably heard of the train-test-split in the context of machine learning, which is fairly intuitive. Show some examples to your model, let it learn and then test it on other examples. But there is one more data split that is used and that is the train-validation-test split or sometimes achieved by using cross-validation.……
