knnn 0.0.8

An implementation of KNNN algorithm

knnn

K-Nearest Neighbors of Neighbors

pip install knnn

Description

This package provides a simple implementation of the K-Nearest Neighbors of Neighbors algorithm. The algorithm is a simple extension of the K-Nearest Neighbors algorithm, which is used for anomaly detection. The algorithm is based on the idea that the neighbors of the neighbors of a point gives more information than its neighbors. The algorithm can be used to improve the accuracy of the KNN algorithm.

Usage

from knnn import KNNN
import numpy as np

# Random data
x_normal = np.random.rand(100, 2)
x_test = np.random.rand(20, 2) + 1

# Create a KNNN object
knnn = KNNN(num_neighbors=3, num_neighbors_of_neighbors=25)
# Fit the model
knnn.fit(x_normal)
# Predict the labels of the test data
y_pred = knnn.predict(x_test)

Installation

The simplest way to install the package is to run:

pip install knnn
