UNNEModelData | Unreal Engine 5.7 Documentation

This class represents assets that store neural network model data.

Neural network models typically consist of a graph of operations and corresponding parameters as e.g. weights. UNNEModelData assets store such model data as imported e.g. by the UNNEModelDataFactory class. An INNERuntime object retrieved by UE::NNE::GetRuntime(const FString& Name) can be used to create an inferable neural network model.
