Goscore

Go scoring API for Predictive Model Markup Language (PMML).

Currently supports Neural Network, Decision Tree, Random Forest and Gradient Boosted Models

Will be happy to implement new models by demand, or assist with any other issue.

Tutorial - Deploy Machine Learning Models from R Research to Go Production with PMML

Installation

go get github.com/asafschers/goscore

Usage

Random Forest / Gradient Boosted Model

Generate PMML - R

Fetch model from PMML file -

modelXml, _ := ioutil.ReadFile("fixtures/model.pmml")
var model goscore.RandomForest // or goscore.GradientBoostedModel
xml.Unmarshal([]byte(modelXml), &model)

Set features -

features := map[string]interface{}{
  "Sex": "male",
  "Parch": 0,
  "Age": 30,
  "Fare": 9.6875,
  "Pclass": 2,
  "SibSp": 0,
  "Embarked": "Q",
}

Score features by model -

score, _ := model.Score(features, "1") // gbm.score doesn't recieve label

Score faster -

runtime.GOMAXPROCS(runtime.NumCPU()) // use all cores
score, _ := model.ScoreConcurrently(features, "1") // parallelize tree traversing

    Question: performance

    Hello, @asafschers ! Can you, please, provide some information on performance of model?

    1. What's the biggest size of PMML model, that can be served with goscore?
    2. What about memory consumption and scale of time for predictions?

    Support for Decision Trees?

    Hi, I read it in your Readme that this repo supports PMML Decision Trees. However, I am not able to find a module that actually implements a decision tree scorer. The tree.go seems to implement and support GBT and Random Forest, but does not seem to be a standalone model that can be used to score. Do you know if Decision Trees are supported currently?
