Statistical methods such as Euclidean distance, cosine similarity, k-means, and Pearson correlation coefficient can be used to measure differences between benign and malicious models.
“The first one is a similarity-based malicious model detection algorithm, which considers that statistical methods (such as euclidean distance [40], [52], cosine similarity [37], [38], k-means [46], Pearson correlation coefficient [49], [51], etc.) can be used to measure the differences between benign and malicious models [36], [80].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
