This challenge is scored using equally weighted MBE and RMSE. Since RMSE is always non-negative, a negative score can only occur if the MBE component is sufficiently negative. A negative MBE indicates that the predictions are below the true target, i.e. the submission is generally underestimating the target.

If you try running the demo notebook and submit the file it gives, it should get you above the baseline then you can continue from there
