When I was a little girl I once spent a week disassembling a telephone down to the nuts and bolts. Worried at the dangerous parts she saw, mom called the phone company, who said "it's fine, but if she puts the phone back together, then tell her to apply for a job."
These days, I still enjoy understanding how things work, and my favorite "dissassembly" tools come from data analysis and machine learning. But now I put them back together.
And I've learned that it's how the pieces work together in an integrated system that really matters, not what they do when apart.
I invented inductive transfer and am evangelizing decision intelligence. I lead machine learning and decision intelligence projects worldwide.
