Sample State Transitions

Object’s life cycle

Let’s look at the life cycles of Sample objects. An object’s life cycle starts with object creation, then state changes, and (in some cases) the end of its processing life when there are no more references to it. We have three scenarios:

Initial load

We’ll need a load() method to populate a TrainingData object from some source of raw data. We can imagine a load() method using a CSV reader to create Sample objects with a species value, making them KnownSample objects. The load() method splits the KnownSample objects into the training and testing lists, which is an important state change for a TrainingData object.

Hyperparameter testing

We’ll need a test() ...
