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.
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.
Anomaly Detection automatically analyzes data and triggers alerts when trends are detected. To start receiving anomalies for a specific report, add the report to the dashboard. Alerts are also generated automatically for any saved report that has been viewed at least twice in the last 60 days.
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.
Anomaly Explanations (“Explains” for short) is the latest machine learning model running in Mixpanel’s automatic anomaly detection product. Whenever Mixpanel detects an anomaly in your data, 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:
Segmentation & Insights
- Daily & weekly time granularity
- Totals & Uniques
- Anomalies for the conversion rate of individual steps as well as the overall conversion rate
- Anomalies on the % of users retaining on a daily time granularity
The feedback you provide (Useful/Not Useful) is used to inform and improve the machine learning that powers Notifications.
Anomaly Requirements and Details
There are several data requirements needed for anomalies to start to be detected.
Segmentation & Insights
- Daily granularity - 120 days of data
- Hourly granularity - 120 hours of data
Funnels & Retention
- 60 days of data + user selected conversion window
Also note that detected anomalies will be prioritized and up to 3 anomalies will be delivered per day.
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.
