Split

[mikeanders]

What is the easiest way to Split a Data File (.cvs) into a Training Set and a Test Set, randomly? This after the Data File has been cleaned and there are no anomalies.

This is in preparation for do K-Nearest Neighbor classification.

Hi @mikeanders ,

You can use the create samples tool in preparation category to do that.

Hi, @mikeanders 

Kindly search for Create Samples Tool and open the example to get a flavor.

I have attached an Alteryx Example for your convenience.

Also, check out this link with regards to random seed, credit @SydneyF

Hi, @mikeanders 

You're most welcome!

[RobertOdera]

Sure thing, @mikeanders 

DM me and I'll share some materials and examples that you might find useful.

Also, if you'd like, check out https://www.alteryx.com/why-alteryx/alteryx-for-good/adapt-program.

As I understand it, the program is free if you're accepted for now and it covers Predictive (which is what you're learning right now!).

Cheers!
