Neural basis of utility estimation.
The allocation of behavior among competing activities and goal objects depends on the payoffs they provide. Payoff is evaluated among multiple dimensions, including intensity, rate, delay, and kind. Recent findings suggest that by triggering a stream of action potentials in myelinated, medial forebrain bundle axons, rewarding electrical brain stimulation delivers a meaningful intensity signal t...
متن کاملUtility Estimation of Health Status of Cancer Patients by Mapping for Cost-Utility Analysis
Background: It is important to obtain accurate information about the preferences of people for measuring quality-adjusted life years (QALYs), because it is necessary for cost-utility analysis. In this regard, mapping is a method to access this information. Therefore, the purpose of this study was to map Functional Assessment of Cancer Therapy – General (FACT-G) onto Short Form Six Dimension (SF...
متن کاملestimation of water saturation from petrophysical logs using radial basis function neural network
estimation of reservoir water saturation (sw) is one of the main tasks in well logging. many empirical equations are available, which are, more or less, based on archie equation. the present study is an application of radial basis function neural network (rbfnn) modeling for estimation of water saturation responses in a carbonate reservoir. four conventional petrophysical logs (pls) including d...
متن کاملEstimation of Industrial Production Costs, Using Regression Analysis, Neural Networks or Hybrid Neural - Regression Method?
Estimation (Forecasting) of industrial production costs is one of the most important factor affecting decisions in the highly competitive markets. Thus, accuracy of the estimation is highly desirable. Hibrid Regression Neural Network is an approach proposed in this paper to obtain better fitness in comparison with Regression Analysis and the Neural Network methods. Comparing the estimated resul...
متن کاملA Cognitive Basis for Context-Dependent Utility
This paper provides a new way to understand the concept of a utility function. By looking into the cognitive processes of information acquisition, I demonstrate how a utility function can be derived from deeper first principles. Crucially, assuming that humans possess only a minimal set of cognitive tools ordinal comparison and proportion (or frequency-of-occurrence) estimation, I show that the...
