# Insights FAQs

#### **What happens when a refresh is set up for an Insight?**

The Insight will refresh/re-run at the scheduled time, irrespective of data refresh, and you will receive a notification. If the data remains unchanged, the resulting insight will be the same.

#### **Why does comparison insight show me the number of rows?**

It could be useful in some cases to assess the frequency comparison between cohorts.

#### **How do you know when to use discovery insights vs. autoML?**

Tellius Insights is still a descriptive output, although it uses predictive modeling on the back end. Use Insights to uncover and quantify relationships between metrics and dimensions in order to explain a particular scenario in the data. ML is used when a certain outcome needs to be predicted (example: predict if a loan is going to be charged off, predict sales for 30 days into the future)

#### **Can you use a custom model for Discovery Insights?**

No, Insights is a fine-tuned framework that produces four types of output at the moment: discovery, segment driver, comparison, and trend.
