Digging for gold in mountains of information!
Imagine walking on a beach looking for shiny rocks.
Most rocks look the same, but occasionally you find a special one!
Data mining is like that - searching through lots of data to find something valuable!
Companies collect TONS of data about us:
🛒 What we buy
🔍 What we search for
❤️ What we like
There's too much data for humans to look at - we need computers to help find patterns!
🔮 Predictions: "What movies will this person like?"
👥 Groups: "What types of customers do we have?"
⬆️ Trends: "Are ice cream sales going up in summer?"
🔗 Connections: "People who buy diapers also buy beer!"
🛒 Walmart: Discovered people buy flashlights before hurricanes!
📱 Netflix: Predicts what shows you'll watch
🏥 Hospitals: Find patients at risk for diseases
🚨 Police: Predict where crimes might happen
📱 Instagram: Shows you content you'll likely enjoy
Data mining can be controversial:
❓ Who has access to your data?
❓ Is it fair to predict things about you?
❓ Should companies know so much about us?
