Cocaine hydrochloride was dissolved in saline, filtered using a 0.45- mm ultracleaning filter unit (Fisher Scientific), and delivered at a dose of 0.4 or 1.0 mg/kg per 0.10 ml infusion. These cocaine doses were selected, because they are reinforcing in both male and female rats (see, eg...

1f). The prominence of the global value maximum relative to alternatives is quantified by Shannon’s entropy of the normalized element weights, a log measure of the number of advantageous actions. Early in learning, the values of all actions are similar, entropy is high, and no clear global ...

where Pijis the control point, wijis the weight of the control point,Ni,p(u)andMj,q(v)are B-spline basis functions. Ultimately, control points and weights were adjusted to optimize the surfaces, ensure proper continuity between adjacent surfaces, and further improve model quality through error...
Also, [44] converts the problem into a per-frame deterministic problem through the Lyapunov optimization technique. Thus, it results in 2 sub-problems, resource allocation, and computation offloading, which are strongly coupled and difficult to solve directly. The authors design a queue-aware compu...
For any vector of weights w, let supp(w) indicate the set of indices i such that wi≠0. • Components Lip and Uip are defined as ≔≔Lip≔0,if wip≥0,N+1,if wip<0, and Uip≔N+1,if wip≥0,0,if wip<0. • The formulation’s Big-Ms are set as M+p=maxz∈[1,...
(subjective) precision of beliefs40,41,42. If one’s belief in the precision of action weights is increased under high DA, this would naturally lead to accepting less evidence prior to committing to a decision. However, given the lack of drug effects on striatal activation, our imaging ...
