Anomaly Detection Alerts: From Logic to UI

Users don't want to stare at dashboards; they want to be told when something is wrong. This lesson covers simple threshold logic and visual 'Critical' states.

Course Syllabus

Module 1: Anomaly Detection Logic

  • •Threshold-based detection: static vs dynamic limits
  • •Moving average calculation (7-day, 30-day)
  • •Z-score method for statistical outliers
  • •IQR (Interquartile Range) for skewed data
  • •Choosing the right method for your data shape

Module 2: Conditional UI States

  • •Designing Normal / Warning / Critical colour states
  • •Conditional class application in React & vanilla JS
  • •Animated alert banners and badge counters
  • •Sparkline charts with threshold bands
  • •Accessibility: colour-blind-safe alert palettes

Module 3: End-to-End Alert Pipeline

  • •Connecting detection logic to UI notification triggers
  • •10% revenue drop rule — implementation walkthrough
  • •Toast notifications vs persistent alert panels
  • •Storing and acknowledging alerts in state
  • •Capstone: live revenue anomaly detection widget
