Polynomial Threshold Function (PTF): A Boolean function represented as the sign of a real polynomial, used to model decision boundaries in high-dimensional spaces.

This function can be many things, but in a perceptron it is a threshold function, often the Heaviside step function, which essentially outputs 1 if the value is high enough or 0 otherwise.

Algorithmic complexity, a cornerstone of theoretical computer science, examines the intrinsic resource requirements of computational problems and the limits of what can be efficiently computed. Within ...
