# About
This repository demonstrates a simple example of the **[LVQ4J library](https://github.com/MeGysssTaa/lvq4j)** usage on the **[Iris Data Set](https://en.wikipedia.org/wiki/Iris_flower_data_set)**, which is, perhaps, the best known study case in the **[machine classification](https://en.wikipedia.org/wiki/Statistical_classification)** field.
# Building and running (Gradle)
**Step 1.** Download or clone this repository.
```bash
git clone https://github.com/MeGysssTaa/lvq4j-example-iris
```
**Step 2.** Build the example.
```bash
cd lvq4j-example-iris
./gradlew build
```
**Step 3.** [Download the Iris Data Set](https://archive.ics.uci.edu/ml/datasets/iris).
**Step 4.** Run the example:
```bash
java -jar build/libs/lvq4j-example-iris-1.0.0.jar
```
**Profit!** If you did everything correctly, the output you'll see will be similar to this:
```
lvq4j-example-iris $ java -jar build/libs/lvq4j-example-iris-1.0.0.jar /mnt/e/iris.csv

# Next steps
**See LVQ4J Wiki** and try playing with the code, and then write an own classifier that makes use of LVQ4J.
