Context-dependent decision-making: a simple Bayesian model.
Many phenomena in animal learning can be explained by a context-learning process whereby an animal learns about different patterns of relationship between environmental variables. Differentiating between such environmental regimes or 'contexts' allows an animal to rapidly adapt its behaviour when context changes occur. The current work views animals as making sequential inferences about current...
متن کاملAdaptive Engagement of Cognitive Control in Context-Dependent Decision Making.
Many decisions require a context-dependent mapping from sensory evidence to action. The capacity for flexible information processing of this sort is thought to depend on a cognitive control system in frontoparietal cortex, but the costs and limitations of control entail that its engagement should be minimized. Here, we show that humans reduce demands on control by exploiting statistical structu...
متن کاملValue-based attentional capture influences context-dependent decision-making.
Normative theories posit that value-based decision-making is context independent. However, decisions between two high-value options can be suboptimally biased by the introduction of a third low-value option. This context-dependent modulation is consistent with the divisive normalization of the value of each stimulus by the total value of all stimuli. In addition, an independent line of research...
متن کاملAdaptive response priors in context-dependent decision-making
Context (such as our location or current goal) informs everyday decisions, both by predicting stimuli and determining relevant responses. How do we develop priors that are general enough to apply in various contexts yet specific enough to maximize reward in a given context? We investigated this using the AX-CPT, a task in which a cue determines which button to press for a probe that appears sec...
متن کاملcontext dependent modeling in continuous speech recognition based on a persian phonetic decision tree
context-dependent modeling is a well-known approach to increase modeling accuracy in continuous speech recognition. the most common way to implement this approach is via triphone modeling. nevertheless, the large number of such models results in several problems in model training, whilst the robust training of such models is often hardly obtained. one approach to solve this problem is via param...
