Researchers have introduced a new concept called horospherical depth, designed for statistical analysis on Hadamard manifolds. This depth measure is intrinsically defined and does not rely on linearization or a specific base point, making it more robust. The study proves the existence and properties of the Busemann median, which is derived from this depth, and demonstrates its stability under perturbations and contamination. AI
