  • Measures of Proximity in Data Mining & Machine

    Proximity measures refer to the Measures of Similarity and Dissimilarity. Similarity and Dissimilarity are important because they are used by a number of data mining techniques, such as clustering, nearest neighbour classification, and anomaly detection. We will start the discussion with high-level definitions and explore how they are related.
