Simplicity Learning
– Object detection very complex
– Breakup objects
• Learn one type of object at a time
• Detect one type of object at a time
– Inspired by 4 year old pre-school best learning practice
• Learn one alphabet per week
• Learn letter “A” five days in a row (reinforcement learning)
– Inspired by drug discovery
• One specific drug for one specific disease
• No panacea
– Based on two decades of research experience
• Transform a complex problem into its simplest components
