Researchers have introduced BER-PEF, a novel framework designed to evaluate the predictability of human mobility patterns. This method utilizes Bayes error rate estimation to establish a unified protocol for comparing different prediction estimators, even when direct ground truth is unavailable. BER-PEF maps various data types, including symbolic sequences, numeric trajectories, and contextual features, into a common space to assess estimator outputs against a reference interval. Experiments on datasets like Foursquare NYC and TKY demonstrate that BER-based estimators can offer more reliable evaluations than existing methods, particularly when considering contextual inputs and structured representations.
