# XGBoostPredictor

C++ header-only thread-safe library of [XGBoost](https://github.com/dmlc/xgboost/) predictor without dependency on xgboost library. 

## Requirements

* C++17 compiler

* [RapidJSON](https://rapidjson.org/) library installed

* XGBoost model saved to [json format](https://xgboost.readthedocs.io/en/latest/tutorials/saving_model.html) (requires xgboost >= 1.0)

## Using library in C++

```cpp

#include "xgboostpredictor.h"

#include 

using namespace xgboost::predictor;

int main()

{

    // load xgboost json model

    XGBoostPredictor predictor("model.json");

    // prepare features (3 features total)

    XGBoostPredictor::Data data(3);

    // set features

    // NOTE: feature 0 is set to 1.2, feature 1 is missing and feature 2 is set to 3.4

    data[0] = 1.2f;

    data[2] = 3.4f;

    

    // make prediction

    const auto prediction = predictor.predict(data);

    // print predicted value

    std::cout << prediction[0] << std::endl;

}

```
