For most machine learning algorithms, overfitting happens when the model complexity or training time is too high.

For k-nearest neighbors, it happens when k is too low (e.g., 1).

#MachineLearning #KNearestNeighbors

Tomorrow (Nov 7), 19:00: an all-new R-ladies bookclub event! We'll be discussing splines and K-nearest neighbors. If you want to participate, sign up via Meetup: https://www.meetup.com/nl-NL/rladies-den-bosch/events/289432128/

R-ladies Utrecht and Den Bosch have joined forces, and we have been discussing "Hands-on Machine Learning with R" (https://bradleyboehmke.github.io/HOML/). No need to read in advance :)
