In this work, we propose a generalized product of experts (gPoE) framework for combining the predictions of multiple probabilistic models. We identify four desirable properties that are important for scalability, expressiveness and robustness, when learning and inferring with a combination of multiple models. Through analysis and experiments, we show that gPoE of Gaussian processes (GP) have th...

many of the behaviors and actions of managers and employees, by moral values. due to lack of work ethic and responsibility in the management of organizations, societies like iran could create problems for large organizations..social responsibility is examined in this paper, using eight experts explain the factors of social responsibility in the oil and gas companies were identified. then, using...

In this paper, we show how a topographic mapping can be created from a product of experts. We learn the parameters of the mapping using gradient descent on the negative logarithm of the probability density function of the data under the model. We show that the mapping, though retaining its product of experts form, becomes more like a mixture of experts during training.

It is possible to combine multiple non-linear probabilistic models of the same data by multiplying the probability distributions together and then renormalizing. A “product of experts” is a very efficient way to model data that simultaneously satisfies many different constraints. It is difficult to fit a product of experts to data using maximum likelihood because the gradient of the log likelih...

This paper studies a market for new projects with endogenous information acquisition by experts (venture capitalists). It nds that the crowd-like behavior of experts is characteristic of investments in new elds where prospects of new projects are unknown but correlated and experts independently collect small bits of information: each expert acquires a signal about a project and invests when the...

many factors affect privatization of sports clubs. the aim of this research was to identify social and legal factors affecting privatization of sports clubs and to prioritize them with ahp method. for this purpose, the effective factors were collected with library and field study; a decision hierarchy tree was drawn and a questionnaire was designed. consistency rate under 0.1 was a sign of adap...

the aim of this study was to survey football talent identification problems. all coaches of the basic football teams of tehran asia vision league in adolescent and youth classes formed the statistical population of this study. 42 coaches were selected as the sample based on morgan table. because there was not a standard questionnaire for this scope, a questionnaire with 5-point likert scale was...

− The comparison of three different algorithms for the estimation of parameters of two sine signals with common frequency is presented. The algorithms are the ellipse fit, the seven parameter sine fit and the spectral sinc fit. The comparison includes signal to noise ratio analysis, amplitude analysis and phase difference analysis.
