The concept of transformation of proximity measure was proposed in [112] and experiments on random graphs and some classical datasets revealed an in-crease in clustering quality when using transformed measures In [1] a number of proximity measures including Walk Communicability |

3 PROXIMITY MEASURES Proximity measures quantify the distance or close-ness between two data objects They may be sub-categorized into three types of measures namely sim-ilarity dissimilarity and distance Similarity is a numerical measure that represents the similarity (i e how alike the objects are) between two objects |
What proximity functions can be used for clustering high-dimensional document data?
- Some other similarity measures, such as the cosine similarity, have also been used as prox- imity functions for clustering high-dimensional document data sets . Second, there are a number of choices for the proxim- ity function that can be used in K-means.
How to find the proximity between two clusters using single linkage?
- When we perform clustering using single linkage, we find the proximity between the two clusters by calculating the shortest distance between them. Here we consider the two closest data points of the two clusters to calculate the distance.
What are proximity measures?
- 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.
What are the different distance measures used in clustering?
- There are actually plenty of different distance measures that can be used in a clustering problem, e.g., Manhattan distance, Chebychev distance, Spearman correlation, Minkowski metric as a generalization of Euclidean and Manhattan distances and edit distance.
