Binding

Binding

new Binding(y, x, bopt, normalizedopt)

Description:

  • Implements a macroscopic ersatz of a VSA left-binding/unbinding.

    • Implements the VTB B(y) x and B(y~) x operators, i.e., either
      • the binding of x by the VTB matrix of y,
      • the unbinding of x by the VTB matrix of y~, with B(y~) = B(y)^T.
    • The binding name B(y)_x is calculated from its member name.
    • The binding belief tau = tau_y tau_x and sigma = sigma_0 + sigma_y + sigma_x is calculated from its member belief.
    • Note: a binding can not be copied, use the clone() method instead.

    Extends: Symbol, with all public methods available.

Parameters:
Name Type Attributes Default Description
y Symbol

The y symbol.
x Symbol

The x symbol.
b bool <optional>
 true

If true constructs a binding, if false construct an unbinding.
normalized bool <optional>
 false

If true the mesoscopic computed vector is normalized to a unary magnitude.

Methods

y() → {Symbol}

Description:

  • Returns the binding operator y left parameter.

Returns:

The y value.

Type
Symbol

x() → {Symbol}

Description:

  • Returns the binding operator x left parameter.

Returns:

The x value.

Type
Symbol

b() → {bool}

Description:

  • Returns the binding/unbinding flag.

Returns:

If true the operation is a bindind, if false it is an unbinding.

Type
bool

normalized() → {bool}

Description:

  • Returns the normalize flag.

Returns:

If true mesoscopic computed vector is normalized to a unary magnitude.

Type
bool

asString() → {String}

Description:

  • Returns the value as a string.

Returns:

A string of the B_(y)(x)_<belief> for binding or B_(y~)(x)_<belief> for unbinding, omitting the belief if tau=1, sigma=0.

Type
String

(static) getComputationTIme() → {double}

Description:

  • Returns an estimation of the computation time

    • It has been calibrated on a Intel® CoreTM i5-8265U CPU @ 1.60GHz × 8 cores processorwith no use of GPU.
Returns:

A computation time order of magnitude estimation in milli-seconds.

Type
double
