Q/A: Could Go Become the Next Great Programming Language for AI?

While Go may never be a language of choice for data exploration and building complex machine learning models, it is the engineer's best friend when it comes to making the rest of the process possible.

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. During KotlinConf 2018, I had

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

Introducing My New Pet Project: Should I HODL

My crypto-obsession from last year might have died down a little, but I still remain a long-term investor and a believer of decentralization. Moreover, it was predicting the crypto market's next move that made dust off some of my old machine learning experiments and gave a fresh boost to my

via Why so many data scientists are leaving their jobs So to be an effective data scientist in industry it doesn’t suffice just to do well in Kaggle competitions and complete some online courses. It (un)fortunately (depending on which way you look at it) involves understanding how hierarchies

[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/
