    2 Vision / goal

    +
    +

    +Provide hackable, versioned, optimized, distributed, geometrical, +arbitrary dimensional (hypercube based) data storage and computation +engine (as inspired by the brain) for general purpose visual computing +environment called Sixth. +

    + +

    +Because Lisp is hackable self defined programmable programming +language it would be used to provide imperative programming support. +

    +

    3.2 CM-1 Connection Machine

    +
    +

    +https://en.wikipedia.org/wiki/Connection_Machine +

    + +

    +Massively parallel (thousands of CPUs) connected via +machine's internal 12-dimensional hypercube network allows to +efficiently simulate arbitrary dimensional hypercube and network +topology between computational units. So that when we are +solving/simulating for example 5 dimensional problem, we can arrange +computational units into virtual 5D network. See: +http://www.mission-base.com/tamiko/theory/cm_txts/di-ch2.html +

    + +

    +we can pre-distribute data across computation units and perform +parallel geometrical computation. +

    4 Reasons for hypercube as a so called first class citizen

    +
    +
      +
    • Hypercube is quite general purpose data structure that naturally +encapsulates wide variety data and problems. +
      • + +
    • Nicely captures apparent properties of the brain. +
      • + +
    • Naturally supports distributed and parallel geometrical data storage +and computation. +
      • + +
    • Dedicated hardware like CM-1 can be built around hypercube concept +that results in data, computation process and hardware, all +beautifully fitting together while complementing each other +strengths. +
      • + +
    • Hypercube stored data (and computation process) has geometry by its +nature and should fit nicely with "3D first" user interface ideology +of the parent Sixth project. +
      • +
    +
    +
    +
    +

    5 Geometrical computation idea

    +
    +
    +
    +

    5.1 Distributed computation and data storage

    +
    +

    +Lots of problems can be translated to geometry (use any shapes and as +many dimensions as you need). Solution(s) to such problems could be +then found via geometrical search/comparison/lookup results. As a +bonus, such geometrical *data storage* AND *computation* can be +naturally made in *parallel* and *distributed*. +

    + +

    +Learning means building/updating/re-balancing the model (the hard +part). Question answering is making (relatively simple) lookups +(geometrical queries) against the model. +

    +
    +
    +
    +

    5.2 Mapping hypercube to object-oriented model and relational database

    +
    +

    +Object oriented programming is inspired by the way human mind +operates. It allows programmer to express ideas to computer in a more +human-like terms. +

    + +

    +It is actually also possible to map object model and relational +database to geometrical hyperspace: +

    -
  • Program author:
    • +
  • Object or database table row is a point in hypercube arbitrary +dimensional space. Each object member variable or database table +column can be mapped to its own dimension in hypercube. That is: if +class declares 4 variables for an object, then corresponding object +can be stored as a single point inside 4 dimensional +hypercube. Variable values translate to point coordinates in that +hypercube. That is: numbers and string can be translated to linear +value that can be used as a coordinate along particular dimension. +

  • other applications hosted at svjatoslav.eu
    • +
  • Each object class or database table declares its own hypercube that +contain instances (objects) of that class or rows of a table. +
    • +
+
+
+ +
+

5.3 Mapping entity relations in hypercube

+
+

+Consider we want to create database of: +

+
    +
  • Books. +
    • +
  • Authors. +
    • +
  • Effort: Amount of time contributed by every author to every book +that he/she wrote. +
+

+Information above can be represented as 3D cube where dimensions are: +

+
    +
  • X: Book +
    • +
  • Y: Author +
    • +
  • Z: Effort +
    • +

+Points in that cube would nicely capture many to many relations +between authors and the books. +
