How to take samples from the search space?

[khwstolle]

I have some classification model set-up in the build_model() method and create an AK graph as follows:

node_in, node_out = build_model()

graph = ak.graph.Graph(inputs=node_in, outputs=node_out)

I want to now save some specific configurations of hyperparameters to a Keras model stored on my disk. Something along the lines of the following psuedocode:

hp = find_parameters(graph)
hp["specific_parameter"] = specific_value

model = graph.build(hp)
model.save()

I've however no clue as to how I can set those hyperparameter values. What would be the best way to go about this?
