| Summary : A Data-Driven Similarity Kernel on Probability Spaces
|
Description :
We present a rank-based Mercer kernel to compute a pair-wise similarity
metric corresponding to informative representation of data. We tailor
the development of a kernel to encode our prior knowledge about the
data distribution over a probability space. The philosophical concept
behind our construction is that objects whose feature values fall on
the extreme of that feature’s probability mass distribution are more
similar to each other, than objects whose feature values lie closer to
the mean. Semblance emphasizes features whose values lie far away from
the mean of their probability distribution. The kernel relies on
properties empirically determined from the data and does not assume an
underlying distribution. The use of feature ranks on a probability
space ensures that Semblance is computational efficacious, robust to
outliers, and statistically stable, thus making it widely applicable
algorithm for pattern analysis. The output from the kernel is a square,
symmetric matrix that gives proximity values between pairs of
observations.
