WebbIn general, our proposed new shape constrained set func-tion learning is applicable whenever one is estimating a measurement from a set of noisy measurements, and has side information about how noisy each measurement is. The monotonicity shape constraints can be applied to multi-ple primary features, and the new conditioning shape …
