Unsupervised Effectiveness Estimation Through Intersection of Ranking References
(2019-01-01)
Estimating the effectiveness of retrieval systems in unsupervised scenarios consists in a task of crucial relevance. By exploiting estimations which dot not require supervision, the retrieval results of many applications ...
Semiparametric estimation and inference using doubly robust moment conditions
(2013-12-05)
We study semiparametric two-step estimators which have the same structure as parametric doubly robust estimators in their second step. The key difference is that we do not impose any parametric restriction on the nuisance ...
Unsupervised Effectiveness Estimation for Image Retrieval Using Reciprocal Rank Information
(2015-10-30)
In this paper, we present an unsupervised approach for estimating the effectiveness of image retrieval results obtained for a given query. The proposed approach does not require any training procedure and the computational ...
Efficient semiparametric estimation of quantile treatment effects
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2003-01)
This paper presents calculations of semiparametric efficiency bounds for quantile treatment effects parameters when se1ection to treatment is based on observable characteristics. The paper also presents three estimation ...
Genetic parameters estimates for milk, fat and protein yield analyzed by test day models for Murrah buffaloes in Brazil
(Pagepress Publ, 2007-01-01)
The objectives of this study were to estimate genetic parameters for test-day milk, fat and protein yields, in Murrah buffaloes. In this study 4,757 complete lactations of Murrah buffaloes were analyzed. The (co) variance ...

Unsupervised measures for estimating the effectiveness of image retrieval systems
(2013-12-01)
The main objective of Content-Based Image Retrieval (CBIR) systems is to retrieve a ranked list containing the most similar images of a collection given a query image, by taking into account their visual content. Although ...
Quality of service parameters and link operation point estimation based on effective bandwidth
(UR. FING, 2003)
This work addresses the estimation and calculation of the operating point of a networks link in a digital traffic network. The notion of operating point comes from Effective Bandwidth (EB) theory. The results are valid ...
Quality of service parameters and link operation point estimation based on effective bandwidth
(Elsevier, 2005)
This work addresses the estimation and calculation of the operating point of a network's link in a digital traffic network. The notion of operating point comes from effective bandwidth (EB) theory. The results shown are ...
