Показать описание
K- Near Neighbors (KNN) is a simple algorithm in pattern recognition. It is a non-paramentric method, which measures distance between the scenario of a single query and a set of scenarios in a data set. It is mainly used for classification and regression. Following are the topics covered in the video:
1. KNN Algorithm (Example)
2. KNN Algorithm- Significance
3. KNN Algorithm- Pros & Cons
4. Building the Classifier
5. Executing the Classifier
6. Testing a Classifier
7. Clustering

What the libraries did you use to make the knn.py library. I don't see the top of the code in knn.py.

What is I want to predict labels for a data frame, rather than an array? That means the group is a data frame containing two variables (x, y). And I want to predict the labels for these pairs from a data frame.
