knearest neighbors algorithm  Wikipedia
In statistics, the knearest neighbors algorithm (kNN) is a nonparametric supervised learning method first developed by Evelyn Fix and Joseph Hodges in 1951, and later expanded by Thomas Cover. It is used for classification and regression.In both cases, the input consists of the k closest training examples in a data set.The output depends on whether kNN is used for classification or regression:
Machine Learning Basics with the KNearest Neighbors Algorithm
ABC. We are keeping it super simple! Breaking it down. A supervised machine learning algorithm (as opposed to an unsupervised machine learning algorithm) is one that relies on labeled input data to learn a function that produces an appropriate output when given new unlabeled data.. Imagine a computer is a child, we are its supervisor (e.g. parent, guardian, or teacher), and we want the child ...
Multiclass classification  Wikipedia
knearest neighbours. knearest neighbors kNN is considered among the oldest nonparametric classification algorithms. To classify an unknown example, the distance from that example to every other training example is measured. The k smallest distances are identified, and the most represented class by these k nearest neighbours is considered the ...

Refer to the KDTree and BallTree class documentation for more information on the options available for nearest neighbors searches, including specification of query strategies, distance metrics, etc. For a list of available metrics, see the documentation of the DistanceMetric class and the metrics listed in sklearn.metrics.pairwise.PAIRWISE_DISTANCE_FUNCTIONS.
2 Knearest Neighbours Regression  Machine Learning for ...  Bookdown
2 Knearest Neighbours Regression. 2.1 Introduction. KNN regression is a nonparametric method that, in an intuitive manner, approximates the association between independent variables and the continuous outcome by averaging the observations in the same neighbourhood. The size of the neighbourhood needs to be set by the analyst or can be chosen ...

KNearest Neighbors (KNN) The knearest neighbors algorithm (kNN) is a nonparametric, lazy learning method used for classification and regression. The output based on the majority vote (for ...
Sobel operator  Wikipedia
The Sobel operator, sometimes called the Sobel–Feldman operator or Sobel filter, is used in image processing and computer vision, particularly within edge detection algorithms where it creates an image emphasising edges. It is named after Irwin Sobel and Gary Feldman, colleagues at the Stanford Artificial Intelligence Laboratory (SAIL). Sobel and Feldman presented the idea of an "Isotropic 3 ...
