Extended Data Fig. 4. Model performance evaluated before and after exclusion of volumes with unreliable decoding.

Here, before computing model performance we filtered out either the 0%, 20% or 50% least reliable volumes (that is those with the highest predicted error (PE)). Model performance is expressed as the coefficient-of-determination R²-score implemented in scikit-learn⁴⁰ between true and decoded gaze trajectory for the five key datasets featuring fixations, 3x smooth pursuit and visual search. Note that R² can range from negative infinity to one. We plot single-participant data (dots) as well as the mean ± standard error of the mean (line plots). Participant dots were additionally color coded according to the participants’ PE.
