This study examined the effects of stimulus-feedback cooccurrence on rule-based and information-integration category learning. Rule-based categories are those for which a verbalizable rule is optimal. Information-integration categories are those for which the optimal rule is nonverbalizable. Participants performed a rule-based or an information-integration task where the stimulus co-occurred wi...

The present contribution focuses on the integration of word senses in a vector representation of texts, using a probabilistic model. The vector representation under consideration is the DSIR model, that extends the standard Vector Space (VS) model by taking both occurrences and co-occurrences of words into account. Integration of word senses into the co-occurrence model is done using a Markov R...

The development of computational solutions for simulation of visual behavior deals with the problem of integration and co-operation between different computational processes for control of active vision systems. In general these computational processes could emulate different and specific artificial visual behavior and their integration presents distinct facets and problems. The first is the in...

Co-integration models the long-term, equilibrium relationship of two or more related financial variables. Even if cointegration is found, in the short run, there may be deviations from the long run equilibrium relationship. The aim of this work is to forecast these deviations using neural networks and create a trading strategy based on them. A case study is used: co-integration residuals from A...

Submitted: Jul 2, 2013; Accepted: Aug 14, 2013; Published: Aug 29, 2013 Abstract: The main focus of the study is to find the determinants of money demand in Pakistan. We used disaggregated expenditures approach in this regard. To find the co-integration among the variables of the model, Johansen co-integration approach is utilized. The results of the study show that the co-integration exists am...

BACKGROUND Studies have shown that early ART initiation in TB/HIV co-infected patients lowers mortality. One way to implement earlier ART commencement could be through integration of TB and HIV services, a more efficient model of care than separate, vertical programs. We present a model of full TB/HIV integration and estimate its effect on time to initiation of ART. METHODOLOGY/PRINCIPAL FIND...

The present paper is aimed at studying the nature of the causal relationship between stock prices and macroeconomic variables in India, if any such relationship exists. For this purpose the techniques of unit– root tests, cointegration and the Granger causality test have been applied between the NSE Index ‘Nifty’ and the macroeconomic variables, viz., Real effective economic rate (REER), Foreig...

This paper examines the causal relationship between energy use and real GDP for the period 1967-2002 in Iran. The results of Phillips- Perron test indicate that the real GDP and the four categories of energy, i.e. coal, oil, gas, and hydroelectric energy are integrated of order one. Besides, the Johansen — Juselius maximum likelihood co- integration tests imply the existence of Granger causalit...
