Wisdom of the Crowds in Minimum Spanning Tree Problems
The „wisdom of the crowds‟ effect describes the finding that combining responses across a number of individuals in a group leads to aggregate performance that is as good as or better than the performance of the best individuals in the group. Here, we look at the wisdom of the crowds effect in the Minimum Spanning Tree Problem (MSTP). The MSTP is an optimization problem where observers must conn...
متن کاملThe wisdom of crowds in one mind: Experimental evidence on repeatedly asking oneself instead of others
Under the right circumstances, groups can be remarkably intelligent and statistical aggregates of individuals’ decisions can outperform individual’s and expert’s decisions. Examples of this wisdom of crowds effect range from markets, auctions, political polls, internet search engines to quiz shows (Galton, 1907; Lorge, Fox, Davitz, & Brenner, 1958; Surowiecki, 2004; Page, 2007; Mannes, 2009). R...
متن کاملThe Wisdom of Crowds with Informative Priors
In some eyewitness situations, a group of individuals might have witnessed the same sequence of events. We consider the problem of aggregating eyewitness testimony, trying to reconstruct the true sequence of events as best as possible. We introduce a Bayesian model which incorporates individual differences in memory ability, as well as informative prior knowledge about event sequences, as measu...
متن کاملWised Semi-Supervised Cluster Ensemble Selection: A New Framework for Selecting and Combing Multiple Partitions Based on Prior knowledge
The Wisdom of Crowds, an innovative theory described in social science, claims that the aggregate decisions made by a group will often be better than those of its individual members if the four fundamental criteria of this theory are satisfied. This theory used for in clustering problems. Previous researches showed that this theory can significantly increase the stability and performance of...
متن کاملModeling Wisdom of Crowds Using Latent Mixture of Discriminative Experts
In many computational linguistic scenarios, training labels are subjectives making it necessary to acquire the opinions of multiple annotators/experts, which is referred to as ”wisdom of crowds”. In this paper, we propose a new approach for modeling wisdom of crowds based on the Latent Mixture of Discriminative Experts (LMDE) model that can automatically learn the prototypical patterns and hidd...
