We present an extension to the Mixture of Experts (ME) model, where the individual experts are Gaussian Process (GP) regression models. Using an input-dependent adaptation of the Dirichlet Process, we implement a gating network for an infinite number of Experts. Inference in this model may be done efficiently using a Markov Chain relying on Gibbs sampling. The model allows the effective covaria...

Recently, Hummel and Landy proposed a variation on the Dempster/Shafer theory of evidence that tracks only the first and second order statistics of the opinions of sets of experts. This extension permits the tracking of statistics of probabilistic opinions, however, as opposed to tracking merely Boolean opinions (or possibilities within the "frame of discernment"). Both the Dempster/Shafer form...

The paper presents an investigation of the differences between two experts in the same domain. The observed differences concern comparisons between domain objects, rule justifications (technical vs.pragmatic justifications, naïve physics reasoning), and categorical knowledge (logic, level, and extension of the categorization). Differences are attributed to the prior experience of the two expert...

We introduce an extension to annealed importance sampling that uses Hamiltonian dynamics to rapidly estimate normalization constants. We demonstrate this method by computing log likelihoods in directed and undirected probabilistic image models. We compare the performance of linear generative models with both Gaussian and Laplace priors, product of experts models with Laplace and Student’s t exp...

"We are not experts in the technology we buy. We are experts in the technology of logistics and supply chain integration.” Richard L. Hunter, Dell Computer "The Internet offered a logical extension of our direct model,...we used Internet browsers to essentially give the same information to our customers and suppliers -bringing them literally inside our business. This became the key to what I ca...

There has been much work on extending the prediction with expert advice methodology to the case when experts are composed of components and there are combinatorially many such experts. One of the core examples is the Online Shortest Path problem where the components are edges and the experts are paths. In this note we revisit this online routing problem in the case where in each trial some of t...

the purpose followed in this study was to analyze barriers of agriculture biotechnology development in iran. the research method was a descriptive and correlational one. the statistical population consisted of agricultural biotechnology specialists in the tehran province of whom n=108 were taken through census method to take part in the study. finally 85 questionnaires (research instrument) wer...

this paper describes the extension requirements in use of drip irrigation systems in tehran province. the study was functional (practical) in terms of goal, non-experimental in terms of control on variables, and causality-relational in terms of data collection. data collection method was based on the documentary-library and field study (questionnaire) and statistical population included 547 sam...

The main purpose of this study was to investigate the role of Knowledge Management (KM) in Organizational Entrepreneurship (OE) among agriculture extension workers at Kermanshah Township, Iran. The statistical population in this study consisted of all agriculture extension workers of Jihad-e-Agriculture management and centers of agricultural services at Kermanshah Township (N=143), of whom 129 ...

considering the importance of extension agent as the mediator between farmers and experts, and their effective role in the transfer of knowledge and technology to farmers with the aim of achieving a sustainable agriculture system, the main purpose of this research was to analysis of the affecting factors on improvement of performance of extension agent from the farmers’ viewpoint in zahak towns...
