<p>We propose a new pattern representation scheme based on data compression, or PRDC, for media data analysis. PRDC is composed of two parts, an encoder that translates input data into a text and a set of text compressors to generate a compression ratio vector (CV). The CV is used as a feature of the input data. By preparing a set of media-specific encoders, PRDC becomes widely applicable. Analysis tasks, both categorization (class formation) and recognition (classification), can be realized using CVs. After a mathematical discussion on the realizability of PRDC, the wide applicability of this scheme is demonstrated through automatic categorization and/or recognition of music, voice, genome, handwritten sketches, and color images.</p>
