A good account of our data was provided by a variant of the leaky competing accumulator model, in which reward offsets the starting place of a competitive, inhibition-dominant, activation process.
A wide range of studies in mammals have provided support for a model in which reward is signaled in the brain by increased activity of dopaminergic neurons in VTA, and subsequent phasic dopamine release into forebrain areas [1] [3].
Perhaps you meant there is no temporal integration into the future at all? Reviewer #2: The authors describe a model in which reward is operationally defined and computed according to the degree to which an outcome reduces the distance between the animal's current state and an idealized homeostatic state (setpoint).
The appropriate model of nucleotide substitution for each gene was evaluated using Modeltest 3.7 [34]; selection of models was based on the Akaike Information Criterion (AIC), which rewards models for good fit but penalizes them for unnecessary parameters [35].
His object is to do away with Brazil's traditional development model of transferring wealth from the international sectors of the economy, what he calls a "neo-Korean model," which has traditionally rewarded the largest businesses with favorable tax treatment.
The state-reward assigned to each state of the model is interpreted as the rate at which rewards are accumulated in that state, i.e. if t time units are spent in a state with state-reward r, the accumulated reward in that state is r × t.
The new model includes two types of funding: formula based funding, which is adjusted for qualitative factors, such as major sources of external financing, absorptive capacity, and risk; and, incentive funding, which rewards well-performing programs.
There are several theoretical approaches to these problems, for example the imbalance effort - reward (ERI) model, which has been poorly tested in the ICUs.
Based on the reward-mapping-enabled intermediate model, we specify reward structures in the composite base model which is built on three stochastic activity network reward models.
