Experiments endpoint
Model development and training occurs at the Experiment level, where an Experiment consists of an MLInstance, training runs, and scoring runs.
Create an Experiment create-an-experiment
You can create an Experiment by performing a POST request while providing a name and a valid MLInstance ID in the request payload.

Response
A successful response returns a payload containing the details of the newly created Experiment including its unique identifier (id
).

Create and execute a training or scoring run experiment-training-scoring
You can create training or scoring runs by performing a POST request and providing a valid Experiment ID and specifying the run task. Scoring runs can be created only if the Experiment has an existing and successful training run. Successfully creating a training run will initialize the model training procedure and its successful completion will generate a trained model. Generating trained models will replace any previously existing ones such that an Experiment can only utilize a single trained model at any given time.
