Abstract: Apparatus for reducing the volumes occupied by data, comprising: (1) a source systems data profiler and extractor subsystem, (2) a stage 1 data reduction subsystem (2), (3) a stage 2 data reduction persistent homology machine (3), (4) a stage 3 data reduction holographic producer (4). The apparatus uses information density holography to reduce the data volumes and may be used in many applications including cybernetic control in spacecraft, autonomous vehicles and manufacturing plant robotics.
