## Introduction

Matlab code of SMCL (Self-Adaptive Multi-Prototype-based Competitive Learning)

Author: [Yang Lu](https://jasonyanglu.github.io/)

Contact: lylylytc@gmail.com

## Demo

Number of seed points are gradually increased until one seed point is driven away by competitive learning.

## Usage

Directly run smcl.m with dataset name as argument. For example:

```shell
smcl gaussian
```

## Output Example

The codes output four figures and a set of numerical metrics.

Command line output:

```
>> smcl gaussian
