Brain-inspired model for early vocal learning and correspondence matching using free-energy optimization

Framework of the INFERNO architecture for audio primitive retrieving based on iterative optimization through the cortico-basal ganglia loop (CX-BG).
The Primary Auditory Cortex (PAC) receives and categorizes the audio vectors as a first stage, the Superior Temporal Gyrus cortex (STG) integrates over time its outputs that are eventually categorized by the Striatum (STR) in the basal ganglia. The Globus Pallidus (GP) searches and retrieves the audio vectors that best match the STG dynamics recognized by the striatal units. The iterative optimization process is carried out by minimizing noise with a temporal difference reinforcement signal.
