This tool estimates the entropy of your dataset using the K-Nearest Neighbors method.

# Entropy Estimator KNN Calculator

Welcome to the Entropy Estimator KNN Calculator. This tool allows you to estimate the entropy of a given dataset using the k-nearest neighbors (KNN) method. Please provide the necessary parameters in the fields above and click “Calculate” to see the results.

## How to Use:

- Enter the value of
**k**, which represents the number of neighbors to consider for each point in your dataset. - Provide the
**data points**as comma-separated values. Each data point should be represented by the same number of dimensions. - Specify the
**number of dimensions**, which is the number of values in each data point. - Click the
**Calculate**button to compute the entropy.

## Explanation:

The KNN entropy estimation method works as follows:

- For each point in the dataset, compute the distance to all other points.
- Sort these distances and find the distance to the k-th nearest neighbor.
- Use these distances and the volume of a hypersphere to estimate the local density around each point.
- Aggregate these local densities to compute the overall entropy of the dataset.

## Limitations:

- The quality of the entropy estimate depends on the number of points and the choice of k.
- Higher dimensions require more data points for reliable estimates.
- The calculation assumes Euclidean distance; other distance metrics may yield different results.
