Number of source estimation knowledge sources¶
This section focuses on implementation of knowledge sources for the estimation of active sound sourcs in an auditory scene within the blackboard framework.
Objects of class
NumberOfsourcesKS implement models, by incorporating
an instance of a model (which has to implement the models.Base
interface) with knowledge about the relationship of auditory cues and the number of active sound sources.
The model gets loaded from directories you specify upon construction, and should be created with the
Estimating the Number of Sound Sources. The model object of
employ any kind of model, such as a linear support vector machine, or a Gaussian
mixture model. The
NumberOfsourcesKS needs access to Auditory front-end signals, thus it is a
Section Auditory signal dependent knowledge source superclass: AuditoryFrontEndDepKS). The model object holds the signal
The knowledge source predicts, based on the incorporated source model the number of active sound sources in the currently received auditory stream.
