Why Neural Nets Beat Hand-Crafted Features
Learning representations instead of engineering them.
What Is a Feature
A feature is a measurable clue you feed a model, like the number of rooms in a house or the brightness of a pixel.
The Old Way
For decades, experts spent weeks hand-crafting features by hand, deciding which edges, ratios, or word counts a model should pay attention to.
