Symbolic Hyperdimensional Vector

A Symbolic Hyperdimensional Vector is very-wide vector data item that represents an information unit.

• Context:
  • It can (typically) be an Integer Vector.
  • It can (typically contain thousands of numbers.
  • It can (typically) be a fundamental element in Hyperdimensional Computing where information is represented using high-dimensional vectors.
  • It can be manipulated using algebraic operations to perform tasks such as pattern recognition, natural language processing, and data mining.
  • It can allow for the encoding of complex structures and relationships in a computationally efficient manner.
  • It can be a form of Analog Representation in computational models.
  • It can be joined with other hyperdimensional vectors to form composite representations.
  • …
• Example(s):
  • Representing words in a natural language processing task as hyperdimensional vectors, where each dimension could represent semantic or syntactic properties.
  • Encoding images as hyperdimensional vectors in a pattern recognition system, where each dimension represents different features or properties of the image.
  • Using hyperdimensional vectors in a robotic mapping system to represent the spatial environment in which the robot operates.
  • …
• Counter-Example(s):
  • Using simple numerical vectors with a low number of dimensions for data representation.
  • Representing data in a relational database as records and fields instead of hyperdimensional vectors.
