Forward pass adds same linear basis function

5

I'm trying to run a pyearth model with `enable_pruning = False` and only linear features with a `max_degree` of `1`. I noticed that the same feature is added twice. See...

Fixing score_samples

1

This version of score_samples scores each sample on a coordinate-by-coordinate basis. It follows the internals of scikit-learn's r2_score implementation in that coordinates that have no variance are arbitrarily set to...

Support for online learning?

3

How feasible would it be to implement online learning, e.g. a `partial_fit()` method, to allow an existing model to be modified with new data? This would also allow for out-of-core...

When an Earth model is fit with labels that have a single dimension (and are of shape (n,1), score_samples is not behaving as expected. The problem is that in the...

Robust Regression

Hi Would it be possible to add a robust regression option to replace the squared error term. This would allow thew model to be less sensitive to out-liers. https://en.wikipedia.org/wiki/Huber_loss Cheers
