2. Pley
Convolutional Neural Network for Images
Used by:
-eidetic.

3. Machine learning is used for two things:
1. Search / Classification
2. Recognition / Matching

4. Key Question
Does this image contain any human face?

5. Key Question
Is this a picture of George Clooney?

6. First Principles
Show images of correct “object”
multiple times
Show images of incorrect “object”
multiple times

7. Traditional Machine Learning
• Lots of training data
• Carefully crafted features
Makes the solution exponentially
difficult
