This article was written by Suresh Kondamudi.Dealing with large datasets is often daunting. With limited computing resources, particularly memory, it can be challenging to perform even basic tasks like counting distinct elements, membership check, filtering duplicate elements, finding minimum, maximum, top-n elements, or set operations like union, intersection, similarity and so on.…See More

The most underutilized function in SQL

This article was written by Tristan Handy.Over the past nine months I’ve worked with over a dozen venture-funded startups to build out their internal analytics. In doing so, there’s a single SQL function that I have come to use surprisingly often. At first it wasn’t at all clear to me why I would want to use this function, but as time goes on I have found ever more uses for it.What is it? md5().Give md5() a…See More

Multicollinearity in Regression Analysis: Problems, Detection, and Solutions

This article was written by Jim Frost.Multicollinearity occurs when independent variables in a regression model are correlated. This correlation is a problem because independent variables should be independent. If the degree of correlation between variables is high enough, it can cause problems when you fit the model and interpret the results. In this blog post, I’ll highlight the problems that…See More

"Very nice post! I belive that the Shanon equation for information theory is related to the definition of Entropy and its nature, so equations 6 and 9 would be connected."

Finding organic clusters in complex data-networks

This article was written by Graph Commons.A common task for a data scientist is to identify clusters in a given data set. The idea is to simply find groups of objects that have more connections or similarities to one another than they do to outsiders. In the study of networks, we use clustering to recognize communities within large groups of…See More

A Data Scientist’s Perspective on Microsoft R

Posted on May 5, 2020 at 10:30am 0 Comments

This article was written by Lixun Zhang.

As a data scientist, I have experience with R. Naturally, when I was first exposed to Microsoft R Open (MRO, formerly Revolution R Open) and Microsoft R Server (MRS, formerly Revolution R Enterprise), I wanted to know the answers for 3 questions:

  • What do R, MRO, and MRS…

Posted on April 18, 2020 at 7:30am 0 Comments

This article was written by Jim Frost.

Imagine you are studying the relationship between height and weight and want to determine whether this relationship differs between basketball players and non-basketball players. You can graph the two regression lines to see if they look different. However, you…
