NettetThe two most widely used opinion pool methods are linear opinion pools and logarithmic opinion pools. Suppose we have n experts, and let pi(θ) represent expert … In particular, Genest and Schervish (Reference Genest and Schervish 1985) consider a Bayesian model of a decision maker learning the opinion of an expert, and investigate when the result of the update coincides with a general version of the linear opinion pool.They show that certain constraints on the model suffice, and that we do not need to specify the Bayesian model in full detail to obtain ...
A Consensual Linear Opinion Pool - ijcai.org
NettetOther methods, such as the classical model, combines probabilistic opinions using a weighted linear average of individual distributions. The benefit to using the linear … NettetOne of the well-known problems with the linear opinion pool is that it can be poorly calibrated. It tends toward underconfidence as the crowd's diversity increases, i.e., as the variance in the individuals' means increases. To address this calibration problem, we propose the exterior-trimmed opinion pool. To form this pool, forecasts with low ... intel snmp subagent download
Deriving the probability of a linear opinion pooling …
Nettet(1981) shows that the linear opinion pool is the only combination which satisfles this marginalization criterion. Hence, it is not possible to flnd a formula for mathematical aggregation which satisfles both requirements. More recent papers dealing with both opinion pools in difierent areas are, among others, Poole and Raftery (2000), Abbas Nettet1. mai 1991 · In this paper, the optimal pool is presented when the data observed by the different members of the group are conditionally independent given θ. When the data … Nettet3. jan. 2024 · The linear opinion pool (LinOP) provides a potential solution to the problem of information fusion. However, the LinOP cannot be directly applied to multi-object fusion since the resulting fused multi-object density, in general, no longer belongs to the same family of the local ones, thus it cannot be utilized as prior information for the next … john c gosling cincinnati 1800s
