Modify the Evaluator and Estimator APIs #150

Open erp12 opened 4 years ago

erp12 commented 4 years ago

Evaluators should support custom loss functions to compare the actual and expected outputs of program.

The .fit() method of the estimator should support either:

.fit(X, y, loss_fn) where loss_fn is a custom loss function.
.fit(evaluator) where evaluator is an instance of an evaluator to use in place of a dataset.

@erp12 This indeed seems to be a big limitation of the library/API.

Are you planning to work on this?

The last commit was 4 months ago, it seems that you're not planning to work on this and the other issues any time soon.

This project is not abandoned :)

I dedicate some of my free time to the development of PyshGP (and other projects) and I am currently the only contributor. We all have to choose how to best spend our time, and it isn't every day that this library reaches the top of my priorities.

That said, contributions are always welcome. If you would like to work on a pull request for this, I would be happy to assist you. I can provide more details on what parts of the codebase would need to change, if you are interested.
