Kotlin ❤️ Data Science? (Part 1)

A few days ago, I was invited to give a talk at the Munich Kotlin Users Group meetup (check out my slides here) For quite some time, I have had an idea to promote Kotlin as the missing link between software engineering and Data Science. DuringKotlinConf 2018, I had the chance and the privilege to meet a couple of amazing people, whose talks only helped confirm my thoughts. Mathematical Modeling with Kotlin | Thomas Nield

Data Science on Your iPad

This article is a follow-up transcription to a talk I recently gave at a local Munich machine learning meetup. Unlike my previous talk, this time I wanted to convey the idea of using an iPad for actively running data science experiments, as opposed to passively consuming information. I illustrated my point with a few example iOS applications I personally use on a daily basis, which I hope would be good starting points to get the audience interested in the idea.


Pandas: Finding a Row Where One of Its Values Is at a Minimum/Maximum

Often, we will want to get to get a specific row, which marks the minimum or maximum of one of its columns. Let’s suppose we have the SF Salaries dataset from Kaggle. We want to find the employee name, with the largest total pay benefits. The experience with writing NumPy/Pandas filter conditions will quickly let us produce the following version: sal[sal['TotalPayBenefits'] == sal['TotalPayBenefits'].max()]['EmployeeName'] which is absolutely valid, but is it the only option?
