SCUSUM
A score-function-based change detection method that constructs a detection statistic using the Hyvarinen score, but requires training a score network.
Timeline (last 90 days)
In calibrated anisotropic Gaussian simulations, DI-SCUSUM performs close to likelihood-ratio CUSUM while reducing detection delay by about 91% compared with score-based CUSUM (SCUSUM).
On the MNIST handwritten digits and Oxford-IIIT Pet datasets, DI-SCUSUM exhibits lower conditional detection delay than SCUSUM at comparable false alarm levels.
