The Tangram Ruby gem makes it easy to make predictions with your Tangram machine learning model from Ruby.

Usage

$ gem install tangram

require 'tangram'

model = Tangram::Model.from_path('./heart_disease.tangram')

input = {
  age: 63,
  gender: 'male',
  # ...
}

output = model.predict(input)

Platform Support

Tangram for Ruby is currently supported on Linux, macOS, and Windows with AMD64 CPUs. Are you interested in another platform? Open an issue or send us an email at help@tangram.xyz.

Examples

The source for this gem contains two examples, examples/predict and examples/monitor.

Basic

The basic example demonstrates loading a model from a .tangram file and making a prediction.

To run the example:

$ ruby examples/basic.rb

Advanced

The advanced example demonstrates logging predictions and true values to the Tangram app. Before running the example, run tangram app to start the app running locally, open http://localhost:8080 in your browser, and upload the file examples/heart_disease.tangram to it.

To run the example:

$ TANGRAM_URL=http://localhost:8080 ruby examples/advanced.rb

Now if you refresh the production stats or production metrics tabs for the model you uploaded, you should see predictions and true values.
