Exemple of Confidential AI inference with LightGBM on Klave.

Description

This contract implements a single method getExposureRisk that take user input, load lightGBM model, infer from user input, unload LightGBM model and return results to the user. We use as an example the model we have created for determinating COVID contamination risk - Paper

Build your back-end locally

	}
}

And you should get the following output:

{
   "inferred": 0.5018788418268543,
   "riskIndex": 1,
