Partial order embedding with multiple kernels

This data set contains the aset400 artists and subjective similarity measurements from Ellis, et al [1].  Also included are 5 kernels derived from text and acoustic features associated with the artists, as described in [2].
The variables in the .mat file are as follows:

• Kbio and Ktag are TF-IDF kernels computed from stemmed Last.FM biographies and
  top-100 tags. 
  • bag_* and dict_* contain the bag-of-words and dictionaries for
    each type of document. 
  • T* contain the TF-IDF filtered bags-of-words.
• Kmfcc is a probability product kernel (PPK) over the Gaussian mixture models
  (contained in models).
• Ksm is a PPK derived from semantic multinomials (SM).
• Kchroma is a KL-divergence pseudo-kernel derived from chroma features.
• names is a dictionary of the names of the artists in question.

Similarity measurements are derived from aset400, and encoded as follows:

• indices.csv contains the list of artist index numbers
• triples.csv contains the similarity triples, one per line, encoded by index number.  A line "X,Y,Z" indicates that the similarity between (X,Y) is greater than between (X,Z).
