Anomaly Detection

Anomaly Detection & Smart Mobile Alerts detect important changes in data, send alerts notifying of the anomaly, and provide links to the data where the flag was created. They surface important insights and issues automatically, saving time when analyzing data.

This feature is only available for Enterprise users.

Interested in learning more about how Mixpanel uses machine learning to help surface insights and make data more actionable? Here’s an article that covers Mixpanel’s approach to machine learning.

Anomalies

Anomaly Detection automatically analyzes data and triggers alerts when trends are detected. 

Anomalies can be accessed from the bell icon in the upper right hand corner of the UI. Clicking on an anomaly from the bell will take you to the relevant report where there will be a bubble highlighting the relevant data.

Mixpanel utilizes anomaly detection in both Smart Mobile Alerts on Mixpanel’s mobile app and Web Anomalies in Mixpanel’s webapp. Mixpanel’s approach to anomaly detection is covered in detail here.

Anomaly Explains

Anomaly Explanations (or Explains) is the latest machine learning model running in Mixpanel’s automatic anomaly detection product.  Whenever Mixpanel detects an anomaly in Insights, Explains checks for any segments of users that could be responsible for the unexpected change.  When significant driving segments are found, they’ll be presented with an explanation:

When clicking into the alert, greater detail on the anomaly and its driving segments, with quick links to explore the data further will be shown:

Reports with Anomalies

Anomalies can be detected in the following reports:

Insights

  • Daily time granularity
  • Totals & Uniques

Funnels

  • Anomalies for the conversion rate of individual steps as well as the overall conversion rate

Retention

  • Anomalies on the % of users retaining 

The feedback you provide ("Useful/Not Useful") is used to inform and improve the machine learning models that power Notifications.

Enabling Anomaly Detection

How do Smart Mobile Alerts and Web Anomalies interact?

Currently, the same machine learning model powers both Smart Mobile Alerts and Web Anomalies but alerts are separate from each other. For example, if you have a report on the Mixpanel mobile app but not on a Web Dashboard you may receive Smart Mobile Alerts for it but not Web Anomalies. Additionally, if you have the same reports on mobile and web dashboards you will receive alerts in both places and dismissing an alert in one place won’t affect the other.
