Class JsonRemoteInference<I,O>

java.lang.Object

org.nd4j.remote.clients.JsonRemoteInference<I,O>

Type Parameters:

I - type of the input class, i.e. String

O - type of the output class, i.e. Sentiment

public class JsonRemoteInference<I,O>
extends Object

This class provides remote inference functionality via JSON-powered REST APIs. Basically we assume that there's remote JSON server available (on bare metal or in k8s/swarm/whatever cluster), and with proper serializers/deserializers provided we can issue REST requests and get back responses. So, in this way application logic can be separated from DL logic. You just need to provide serializer/deserializer and address of the REST server, i.e. "http://model:8080/v1/serving"
