Global Model Analysis by Landscaping
نویسندگان
چکیده
How well do you know your favorite computational model of cognition? Most likely your knowledge of its behavior has accrued from tests of its ability to mimic human data, what we call local analyses because performance is assessed in a speciÞc testing situation. Global model analysis by landscaping is an approach that sketches out the performance of a model at all of its parameter values, creating a landscape of how the relative performance abilities of the model and a competing model. We demonstrate the usefulness of landscaping by comparing two models of information integration (Fuzzy Logic Model of Perception and the Linear Integration Model). The results show that model distinguishability is akin to power, and may be improved by increasing the sample size, using better statistics, or redesigning the experiment. We show how landscaping can be used to measure this improvement.

متن کاملDoes micro-variability make models more complex? A comparison between diffusive and linear evidence accumulation
Most theories of how decisions are made assume that the accumulation of evidence from the environment is a noisy process. Recently, models have been proposed which do not have this micro-variability, and as a result are simple in the sense of being analytically tractable. We use a global model analysis method called landscaping to show that in terms of flexibility, simply removing micro-variabi...

متن کاملDynamical behavior of a stage structured prey-predator model
In this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. The stages for prey have been considered. The proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. The model is analyzed by using linear stability analysis to ob...
