Most of the knowledge in the world in the
future is going to be extracted by machines
and will reside in machines.
– Yann LeCun, Director of AI Research, Facebook
1. Fill in gaps in existing knowledge
2. Emulate the brain
3. Simulate evolution
4. Systematically reduce uncertainty
5. Notice similarities between old and new

But what we really need is
a single algorithm that solves all five!
Representation
Probabilistic logic (e.g., Markov logic networks)
Weighted formulas → Distribution over states
Evaluation
Posterior probability
User-defined objective function
Optimization
Formula discovery: Genetic programming
Weight learning: Backpropagation
Much remains to be done . . .
We need your ideas
Home Robots
Cancer Cures 360o Recommenders
World Wide Brains
If we used all our technology resources,
we could actually give people personalized
recommendations for every step of your life.
