WebDec 5, 2024 · Making use of the “Kneedle” algorithm implemented in the Python package “kneed” — Theory When working with data, it is sometimes important to know where a data point’s “relative costs to increase some tunable parameter is no longer worth the corresponding performance benefit” (Satopää, Albrecht, Irwin, and Raghavan, 2011, [2], p.1 ). Webkneed. Knee-point detection in Python. This repository is an attempt to implement the kneedle algorithm, published here.Given a set of x and y values, kneed will return the knee point of the function. The knee point is the point of maximum curvature.
