Please tell me the algorithms for automatic classification (without a training set) of points by geometric properties or other (land, houses, trees). There is a cloud of points (three-dimensional coordinates) and for each point there is the intensity of the reflected wave.
- The wording of the question you are trying to pull an owl on the globe. You need data to figure out which algorithm is right for you. Otherwise, you can use K-means, affinity-propagation, hierarchical clustering, and other kinds of different algorithms up to manual splitting. It is important to see the data in order to choose the algorithm correctly. This is not a trivial task. Before receiving the data, I suggest sending the question for revision. - hedgehogues
