Hi Mohanty, would you please share the heights of the test set so we can keep improving our model (for fun) ? thanks

Hi @TeraFlops,

The grader is accepting submissions again. But your submissions will now be marked as “Post Challenge”.

If you have any trouble making submissions, feel free to shoot us an email.

Cheers, Mohanty

Hello Mohanty,

Thanks for bringing this exciting challenge!

As @TeraFlops, I would like to improve my model.

As written in the Challenge overview the scores have been updated today, they are now computed on 100% of the dataset. Since this update, my old best score dropped a lot. (0.53 ->0.42)

But I just made some post-challenge submissions with the same heights, and I’ve got the same scores as during the challenge (0.53) I think the post-challenge submission still compute automatically the score on the 20%. Is it possible to make it to 100% ?

Cheers, Mat

Hi @MatSchaeff ,

Thats true. I did forget to disable the partial grading. That has been fixed now, and the recent submissions regraded. Thanks for pointing it out.

And the drop in R^2 is to be expected when the test set increases, especially in the case when the predictions were overfitting to the exposed part of the test set.

Cheers, Mohanty
