Bundling

Bundling

new Bundling(nameopt, …symbol)

Description:

  • Implements a macroscopic ersatz of a VSA bundling.

    • A bundling or superposition is created adding new symbols.
    • The bundling belief tau = tau_1 tau_2 ... and sigma = sigma_1 + sigma_2 + ... is calculated from its member belief.
    • Note: a bundling can not be copied, use the clone() method instead.

    Extends: Symbol, with all public methods available.

Parameters:
Name Type Attributes Description
name string <optional>

An optional name. By default, a #index unique name is generated.
symbol Symbol <repeatable>

Symbol added to the bundling from 0 to 8 in this implementation

Methods

add(symbol)

Description:

  • Adds a new symbol to the container.

Parameters:
Name Type Description
symbol Symbol

The symbol to add.

erase(symbolopt)

Description:

  • Erases a symbol in the container.

Parameters:
Name Type Attributes Description
symbol Symbol <optional>

The symbol to erase.

  • Without key argument erases all keys, it is a synonym for clear().

getSorted(countopt) → {JSON}

Description:

  • Returns the bundling symbols as a decreasing tau value sorted associative map.

    • This corresponds to a microscopic implementation of a spike time activity rank sorting mechanism
Parameters:
Name Type Attributes Default Description
count uint <optional>
 0

If count > 0, considers only the count symbols with a maximal tau value, otherwise all symbols.
Returns:

A std::vector<const Symbol*> temporary reference to the sorted list of string representation of symbols.

Type
JSON

get()

Description:

  • Defines an iterator over the bundling symbols, used in a construct of the form:

     for(auto it = bundling.Bundling::get().cbegin(); it != bundling.Bundling::get().cend(); it++) {
   const Symbol& symbol = *(it->second);
   ../..
 }
    • This is NOT a VSA plausible operation (unless another List data structure is used) by a debugging function.
    • The bundling.Bundling::get().size() construct returns the number of symbols in this bundling.
Returns:

A const std::unordered_map < unsigned int, const Symbol* > reference, with symbols indexed by their IDs.
