Understand AI process.
The Learning Process
- Get Data: Collect examples
- Train: AI learns patterns
- Test: Check if AI learned correctly
- Use: AI makes predictions
Example: Teaching AI to Recognize Cats
Step 1: Show 10,000 cat pictures
Step 2: AI finds patterns (fur, ears, whiskers)
Step 3: Test with new cat pictures
Step 4: AI can now identify cats!
Training vs Inference
Training: Teaching AI (takes time)
Inference: AI using what it learned (fast)
Like studying for exam (training) vs taking exam (inference).
Data is Key
More data = Better AI
If you show AI only 10 pictures, it won't learn well.
Show it 1 million pictures, it becomes very accurate!
AI Mistakes
AI can make mistakes, especially:
- With new types of data
- When training data was limited
- When data had errors
Remember
- AI learns from examples
- More data = better results
- Training takes time, using is fast
