WebAug 18, 2024 · T he term proximity between two objects is a function of the proximity between the corresponding attributes of the two objects. 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 … WebThe basic idea underlying similarity-based measures is that molecules that are structurally similar are likely to have similar properties. In a fingerprint the presence or absence of a structural fragment is represented by the presence or absence of a set bit. This means that two molecules are judged as being similar if they have a large number ...
