Machine learning definition
Machine Learning (T. Mitchell, 2006)
A computer program CP learn from experience E
with respect to some class of tasks T and
performance measure P, if its performance at tasks
in T, as measured by P, improves with experience E
Key points
experience E : data
performance measure P : optimization
tasks T : utility

A single device can solve them all:
→ our brain
