WebThese observations suggest the hypothesis that, for all real-world learning tasks, one should expect the presence of both experiential and fictive learning signals. Motivated by this possibility, we used a sequential investment game and fMRI to probe ongoing brain responses to both experiential and fictive learning signals generated throughout ... WebApr 9, 2024 · This paper presents a novel single-phase grid-tied neutral-point-clamped (NPC) five-level converter (SPFLC). Unlike the literature on five-level NPC topologies, the proposed one is capable of inherently balancing the voltage of the DC-link split capacitors. For this purpose, a simple Multicarrier Phase Disposition (MPD) Pulse Width Modulation …
WebErrors derived from fictive outcomes (ongoing differences between what might have been achieved and what was actually achieved) have been considered as an important learning signal that complements classic TD errors, and hence, constitute a second type of “critic” [Chiu et al., 2008; Lohrenz et al., 2007]. It remained unclear how the ... WebDec 31, 2013 · These findings suggest that the variable interaction of cognitive strategies with two important classes of computational learning signals (fictive, reward prediction error) represent one contributing substrate for the variable capacity of individuals to control their behavior based on foregone rewards.
