# How to add new function

This doc explains how to add new function to `ml-commons` with two examples.

## Example 1 - Sample ML algorithm with train/predict APIs
This sample algorithm will train a dummy model first. Then user can call predict API to calculate total sum of a data frame or selected data from indices.

### Step 1: name the function
Add new function name in `common/src/main/java/org/opensearch/ml/common/FunctionName.java`
```
public enum FunctionName {
    ...
    //Add new sample algorithm name
    SAMPLE_ALGO,
    ...
}
```

### Step 2: add input class 
Create new class `common/src/main/java/org/opensearch/ml/common/input/parameter/sample/SampleAlgoParams.java` by implementing `MLAlgoParams` interface.
