Normalized Kernels as Similarity Indices
[chapter]
2010
Lecture Notes in Computer Science
Preserved Fulltext
We show that the designed normalized kernels satisfy the basic axioms of a similarity index unlike most unnormalized kernels. ...
We particularly focus on kernel normalization methods that aim at designing proximity measures that better fit the definition and the intuition of a similarity index. ...
Properties of normalized kernels as similarity indices In this section, we want to better characterize the family of normalized kernels that we have introduced. ...

For a graph representation of a dataset, a straightforward normality measure for a sample can be its graph degree. ...
Considering a weighted graph, degree of a sample is the sum of the corresponding row's values in a similarity matrix. ...
Then the average intra-similarity of the cluster for can be written as follows: x T W x x T x (4) In Eq. 4, W is a symmetric similarity (or affinity) matrix where w ij indicates the similarity between ...
