Our Education System
Everybody is a genius. But if you judge a fish by its ability to
climb a tree, it will live its whole life believing that it is stupid.

Words of Wisdom
The GOOD universities focus on
counting the number of publications…
The BETTER universities focus on
citation numbers and impact factors…
The BEST universities focus on EDUCATION!

O(N3), LASSO
• Dimension reduction: PCA, non-negative matrix factorization, kernel PCA O(N3),
maximum variance unfolding O(N3), Gaussian graphical models, discrete graphical
models
• Clustering: k-means, mean-shift O(N2), hierarchical (FoF) clustering O(N3)

Seven “Giants” of Data
• Basic statistics: means, covariances, etc.
• Generalized N-body problems: distances, geometry
• Graph-theoretic problems: discrete graphs
• Linear-algebraic problems: matrix operations
• Optimizations: unconstrained, convex
• Integrations: general dimension
• Alignment problems: dynamic programming, matching

Seven General Strategies
• Divide and conquer/indexing (trees)
• Function transforms (series)
• Sampling (Monte Carlo, active learning)
• Locality (caching, hashing)
• Streaming (online)
• Parallelism (clusters, GPUs)
• Problem transformation (reformulations)
