Introduction

  • Compression of signals from the environment is critical to an
  • rganism’s success
  • Decompression plays an equally critical role
  • We demonstrate this point by comparing two compression

representations and two decompression procedures

  • Co-occurrence probabilities and holographic vectors
  • Top-n model and Coherencer model
  • Problem
  • Given a single object label and a compressed representation of a database of

labeled images, select four other object labels that occur in a single image

Conclusions

  • This is a preliminary, empirical demonstration that the exclusion of

either side of the compression-decompression dyad in domains that do not explicitly represent key information gives an incomplete description of the process
