Probabilistic Production Selection in Act-R
نویسنده
چکیده
In ACT-R, some subsymbolic mechanisms can be switched on that transform ACT-R into a stochastic theory using random variables to generate choice probabilities. This paper asks for the relation between probabilities of production selection and the corresponding random variables. Starting with the assumption that choice probabilities governing production selection satisfy the requirements of Luce’s choice axiom, it is shown that these probabilities can be generated by a system of independent and identically double-exponentially distributed random variables.

Optimizing of an Integrated Production-Distribution System with Probabilistic Parameters in a Multi-Level Supply Chain Network Considering the Backorder
One of the main arguments in the supply chain is integrated production-distribution planning. Integrated production and distribution of products in a supply chain plays an important role in reducing the costs of the chain. In this paper, a mathematical model for the integrated production-distribution problem in a three-level supply chain, including manufacturing plants, distribution centers and...
متن کاملNovel Radial Basis Function Neural Networks based on Probabilistic Evolutionary and Gaussian Mixture Model for Satellites Optimum Selection
In this study, two novel learning algorithms have been applied on Radial Basis Function Neural Network (RBFNN) to approximate the functions with high non-linear order. The Probabilistic Evolutionary (PE) and Gaussian Mixture Model (GMM) techniques are proposed to significantly minimize the error functions. The main idea is concerning the various strategies to optimize the procedure of Gradient ...

Recognition and classification of Power Quality Distorted Signals (PQDSs) in power systems is an essential duty. One of the noteworthy issues in Power Quality Analysis (PQA) is identification of distorted signals using an efficient scheme. This paper recommends a Time–Frequency Analysis (TFA), for extracting features, so-called "hybrid approach", using incorporation of Multi Resolution Analysis...
متن کاملHybrid Probabilistic Search Methods for Simulation Optimization
Discrete-event simulation based optimization is the process of finding the optimum design of a stochastic system when the performance measure(s) could only be estimated via simulation. Randomness in simulation outputs often challenges the correct selection of the optimum. We propose an algorithm that merges Ranking and Selection procedures with a large class of random search methods for continu...
متن کاملA Pseudo-Deterministic Model of Human Language Processing
This paper proposes, empirically motivates and describes a pseudo-deterministic model of Human Language Processing (HLP) implemented in the ACT-R cognitive architecture (Anderson, 2007). The model reflects the integration of a highly parallel, probabilistic activation and selection mechanism and non-monotonic context accommodation mechanism (with limited parallelism) with what is otherwise a se...
