AI Trend Detector

Objectives

• Parse and visualize time-series data with interactive line charts
• Detect upward/downward trends and seasonal patterns
• Identify change points where the data behavior shifts significantly
• Use AI to explain detected patterns in the context of the data
• Display simple short-term predictions with confidence bands

Hints

• Use moving averages to smooth data before trend detection
• Change point detection can use simple methods like CUSUM
• Provide the AI with trend metadata (slope, duration, magnitude) for better explanations
