“…Compared to a network-only approach [48] and an earlier hybrid inference system [2], error correction has proven more effective at closing the gap between the expected curvature and its numerical estimation. Indeed, beyond-usual contextual information (e.g., level-set values, gradients, and the curvature itself), dimensionality reduction, and regularization have been important factors in achieving the results reported in [1].…”

“…In this manuscript, we propose to address the level-set's curvature shortcomings from a data-driven perspective. The latest developments of Qi et al [46] and Patel et al [47], in particular, have inspired our machine-and deep-learning incursions for solving not only for mean-curvature [1,2,48] but also passive transport [49]. In the pioneering study of Qi et al [46], the researchers fitted two-layered perceptrons to circular-interface samples to estimate curvature from area fractions in the VOF representation.…”
