Heatmaps representing the distribution of predicted trips departing from San Francisco towards any point in the U.S. (left column), or arriving to Miami from any point in the U.S. (right column). (a, b) Ground-truth from the RITA air travel dataset. (c, d) Flickr traces. (e, f) Gravity model. signiﬁcant improvement in the model performance. Spatial cross-validation: U.S. West Coast vs. U.S. East Coast. To extend the analysis of the general- izability of the model, we performed a geographical 2-fold cross-validation in which we split the contiguous United − ◦ States into two roughly symmetric parts, taking by reference the meridian 102 . We trained the model in one half of the U.S. and we then used it to predict the mobility ﬂows inside the other half. To make our test independent from the speciﬁc choice of the spatial partition, we disregarded crossed ﬂows, that is, the traﬃc ﬂows connecting two points in diﬀerent halves of the partition. Table 2 shows the performance in terms of the Pearson correlation ##LTFigure##
