How Neighborly is K-Nearest Neighbors to GIS Pros?

Towards AI

Now, in the realm of geographic information systems (GIS), professionals often experience a complex interplay of emotions akin to the love-hate relationship one might have with neighbors. Enter K Nearest Neighbor (k-NN), a technique that personifies the very essence of propinquity and Neighborly dynamics.

KNNs & K-Means: The Superior Alternative to Clustering & Classification.

Towards AI

We will discuss KNNs, also known as K-Nearest Neighbours and K-Means Clustering. K-Nearest Neighbors (KNN) is a supervised ML algorithm for classification and regression. This means that the input data comes with corresponding output labels that the model learns to predict.
