Modelling similar audiences

mugicagonzalez_

Hello

I was wondering if anyone has some tips for creating a model for identifying similar audiences.
I have a list of 1000+ records (people from a CRM with 80000+ people). Now I would like to identify another 1000 people with a similar profile as they do. 

Any advice on how to start on this issue?

Cheers,
Pello

I think the "Cross Distances" operator does what I'm looking for. Could anyone confirm?

You are absolutely correct. Cross-distance will generate pair-wised distances between request and reference document.
In case there is anything that can be used as prediction labels (loyalty, or customer lifetime value), you can build predictive models for that. 
If you make a predictive model for high-value customer using a CRM with 80000+ people, you can apply the models to future another 1000+ for scoring.
Check out the examples in //Community Samples/Community Real World Use Cases/TelCo Customer Churn/TelCo Customer Churn process 
More learning material can be found under //Training Resources/--Getting Started--/Processes       using the customer churn data
