How to Evaluate your Question Answering System Every Day and Still Get Real Work Done [PDF]
, 2000 In this paper, we report on Qaviar, an experimental automated evaluation system for question answering applications. The goal of our research was to find an automatically calculated measure that correlates well with human judges' assessment of answer ...

Distribution-Free Tests of Independence in High Dimensions [PDF]
, 2017 We consider the testing of mutual independence among all entries in a $d$-dimensional random vector based on $n$ independent observations. We study two families of distribution-free test statistics, which include Kendall's tau and Spearman's rho as ...

Subuniformity of harmonic mean p$$ p $$‐values
Canadian Journal of Statistics, EarlyView.Abstract We obtain several inequalities on the generalized means of dependent p$$ p $$‐values. In particular, the weighted harmonic mean of p$$ p $$‐values is strictly subuniform under several dependence assumptions of p$$ p $$‐values, including independence, negative upper orthant dependence, the class of extremal mixture copulas, and some Clayton ...

, 2017 We introduce so-called "single-index copulae". They are semi-parametric conditional copulae whose parameter is an unknown "link" function of a univariate index only.

Canadian Journal of Statistics, EarlyView.Abstract Intensity–duration–frequency curves are used by a wide range of professionals to manage the risks related to extreme rainfall. In Canada, these curves are produced by Environment and Climate Change Canada on the basis of Gumbel distributions fitted independently for each accumulation period.

Identifying key nodes in complex networks based on an improved gravity model
Frontiers in Physics, 2023 The identification of key nodes in complex networks is a hot topic. Therefore, it attracts increasing attention from different fields, like airline networks and social networks. To identify the key nodes in complex network, we suggest an improved gravity

Hereditary properties of permutations are strongly testable [PDF]
, 2014 We show that for every hereditary permutation property and every ∊0 > 0, there exists an integer M such that if a permutation π is ∊o-far from in the Kendall's tau distance, then a random subpermutation of π of order M has the property P with ...
