Data science similarity measure

WebThe Jaccard similarity measures the similarity between two sets of data to see which members are shared and distinct. The Jaccard similarity is calculated by dividing the number of observations in both sets by the number of observations in either set. WebSep 18, 2024 · Once the transfer is complete, we construct a nearest-neighbor classifier in the target domain, with dynamic time warping as the similarity measure. An experimental evaluation on a number of real-world data sets shows that the overall approach is promising, and that it outperforms unsupervised anomaly detection in the target domain.
