What does NN mean in UNCLASSIFIED
KNN stands for K Nearest Neighbors, a machine learning algorithm used in supervised and unsupervised learning tasks. This algorithm uses a collection of known data points or "neighbors" to make predictions about new data points within an arbitrarily-defined neighborhood. KNN has been used in various fields such as computer vision, speech recognition, finance, and engineering to solve complex problems.

Essential Questions and Answers on Nearest Neighbours in "MISCELLANEOUS»UNFILED"
What is KNN?
KNN stands for K Nearest Neighbors, a machine learning algorithm used in supervised and unsupervised learning tasks.
How does KNN work?
The KNN algorithm starts from the premise that similar instances have similar labels. It then calculates the distance between each input data point with all other points in the dataset in order to find the closest neighbors for that point. Based on these neighbors' labels, it can assign labels or make predictions about the new data point.
What are some applications of KNN?
KNN has been used in various fields such as computer vision, speech recognition, finance, and engineering to solve complex problems.
Does KNN require feature scaling?
Yes, feature scaling is important when using the K Nearest Neighbors algorithm since all features are evaluated equally regardless of their unit-of-measurement or magnitude.
Final Words:
In conclusion, K Nearest Neighbors (KNN) is a popular machine learning technique that can be applied to a wide range of real-world problems. It works by finding the closest “neighbor†data points and using their properties to determine how new data points should be labeled or predicted. Different distance metrics can also be applied whenever necessary depending on the specific dataset at hand thus making it a highly useful tool for many applications.
