xgb2code - generate code for an XGB model

Description

This program takes an XGB model (in JSON format) and generates code for it.

Generating code for a model avoids having to call out to a different language (e.g., C) as well as avoids the need for using the XGB libraries at runtime.

Model Support

Currently binary classification is supported.

Supported Languages

Currently xgb2code supports generating Go code.

Usage

$ ./xgb2code -h
Usage of ./xgb2code:
  -function-name string
        The function name to use. Must be a valid Go function name.
  -go-package-name string
        The package name to use when generating Go code. Must be a valid Go package name.
  -input-json string
        Path to the model as JSON
  -language string
        Language to generate code for. Currently 'go' is supported. (default "go")
  -output-file string
        The file to write to

Example Usage

$ ./xgb2code -function-name predict \
             -go-package-name main
             -input-json testdata/small-model/model.json \
             -language go \
             -output-file predict.go

produces a file predict.go where the primary model prediction function has the signature:

func predict(data []*float32, predMargin bool) float32 {

Installation
