Machine Learning MT23, Perceptrons
Flashcards
Describe a perceptron simply.
Take a weighted sum of input variables, and if it exceeds a threshold, output true or false.
Given weights $w _ 0, \ldots, w _ n$, define a perceptron as a function $f(\pmb x)$ that returns $1$ or $0$.
\[f(\pmb x) = \text{sign}(w _ 0 + w _ 1 x _ 1 + \cdots + w _ nx _ n)\]
