Examples of fixation probability distributions (grayscale landscapes) and empirical fixation data (yellow dot fields). (a) Optimal prediction: distribution landscape generated directly from eye-movement data. (Pearson: 1.000, ROC: 0.813). (b) Chance-level prediction: distribution based on random fixation generation (Pearson: 0.010, ROC: 0.523). (c) Distribution produced by our model (“individual informativeness,” II) using the weighted sum method (Pearson: 0.505, ROC: 0.690). (d) Distribution derived from our model using the weighted product method (Pearson: 0.551, ROC: 0.670).
