BRAINS.PNG

Neural Networks are an approach to artificial intelligence that was first proposed in 1944.  Modeled loosely on the human brain, Neural Networks consist of a multitude of simple processing nodes (called neurons) that are highly interconnected and send data through these network connections to estimate a target variable. In this article, I will discuss the structure and training of simple neural networks (specifically Multilayer Perceptrons, aka "vanilla neural networks"), as well as demonstrate an example neural network created by the Alteryx Neural Network Tool.

Who doesn’t love a good cheat sheet? Nobody, that’s who. Cheat sheets are awesome. They are a great reference for functions you need handy, but don’t have memorized by heart (yet). They can also be a fantastic way for learning and reinforcing components of a programming language. Some people like to keep them saved as a bookmark on their web browser. With all of that in mind, we are proud to present to you an Alteryx – R Cheat Sheet, which features Alteryx specific functions for use in the R Tool. With this cheat sheet, you should be better equipped to take on any R Tool challenges you encounter.

LINEAR REGRESSION.png

Building my first linear regression model turned me into an instant celebrity. My roommate, who has acted as a sounding board for my predictive-analytics-learning progress, now believes I can use Linear Regression to predict the winner of the next horse race. While it would be fun to try, a more applicable use case is predicting how much a customer will spend (which, in the case of horse racing could translate to how much someone might spend on a bet). For my use case, I want to predict how much a Lyft driver can expect to receive on their next fare.

banner1.pngVoronoi Tesselation and Delaunay Trianglulation both perform spatial calculations on a set of irregular points. Voronoi Cells (sometimes referred to as Thiessen Polygons in the GIS world) make up a Voronoi Tesselation, which is the partitioning of a plane into polygons based on a set of points, so that for each point there is a corresponding polygon where the area in the polygon is closer to the corresponding point than any other point. Delaunay Triangulation is when a set of irregular points are divided into triangles, so that no point in the set is inside the circumcircle of any triangle created from the points.

 

Both of these processes have a bunch of really neat spatial analysis applications. In this article, we will talk about their implementation in Alteryx.
