Top 15 Scala Libraries for Data Science in 2018

@machinelearnbot 

In our previous articles, we have discussed the top Python libraries for data science. This time we will focus on Scala, which has recently become another prominent language for data scientists. It has gained popularity mostly due to the rise of Spark, a big data processing engine of choice, which is written in Scala and thus provides native API in Scala. We will not go into an in-depth comparison of Scala vs. Python here, but it's important to note, that, unlike Python, Scala is a compiled language. Hence the code written in it gets executed much faster (comparing to pure Python, and not specialized libraries like NumPy).
