Perfect clustering from pairwise comparisons
We consider a pairwise comparisons model with n users and m items. Each user is shown a few pairs of items, and when a pair of items is shown to a user, he or she expresses a preference for one of the items based on a probabilistic model. The goal is to group users into clusters so that users …

Uncertainty Considerations with the GRIM
… on 63 samples from 41 sources of glass. Pairwise comparisons were calculated to illustrate the difference between using a conventional approach like standard deviation to using uncertainty. The amount of pairwise comparisons more than tripled from standard deviation to uncertainty showing …

HodgeRank: Applying Combinatorial Hodge Theory to Sports Ranking
… these methods, we require data in the form of pairwise comparisons, meaning each voter would have rated items in pairs. An obvious candidate for ranking data in the form of pairwise comparisons comes from sports, where such comparisons are very natural (i.e. games between two teams). We …

Matrix estimation with latent permutations
… as seriation, network alignment and ranking from pairwise comparisons, we study the problem of estimating a structured matrix with rows and columns shuffled by latent permutations, given noisy and incomplete observations of its entries. This problem is at the intersection of shape constrained …

A hybrid technique using minimal spanning tree and analytic hierarchical process to improve functional requirements prioritization
… large set of FRs as in ERP due to high number of pairwise comparisons when the size of FRs is more than ten or twelve. To address this issue, this research proposes a hybrid prioritization technique of Minimal Spanning Trees (MST) and AHP called the Spanning Analytic Hierarchical Process (SAHP) …

Bilateral Asymmetry in Incisors: Implications for Miocene Hominoid Species Diagnosis
… ape genera can be utilized as a "yardstick" for pairwise comparisons of isolated Miocene ape incisors from the two genera Kenyapithecus and Equatorius . The research was designed to help determine whether these fossil teeth could be reliably sorted into one or more than one genera. Both metric …

Active sampling, scaling and dataset merging for large-scale image quality assessment
… sampling method for efficient collection of pairwise comparisons in subjective assessment experiments. In these experiments observers are asked to express a preference between two conditions. However, many pairwise comparison protocols require a large number of comparisons to infer accurate …

A goal Programming R&D project funding model of the US Army Strategic Defense Command using the analytic hierarchy process
… Process (AHP) is used to convert subjective pairwise comparisons of thirty-five major USASDC projects, based on eleven key factors, into ratio-scaled numerical weights. THe AHP coefficients are then used in a linear Goal Program in order to optimize the funding level of each project in Fiscal …

A Bikeability Index for Last-Mile Electric Cargo Cycles
… to compute the weights for each variable using pairwise comparisons. Variables with the highest weights out of 100% include collision risk (24.3%-25.5%), visibility (11.1%-13.0%) and pavement condition (9.9%-12.4%). A simplified scoring index is derived using variables that could easily be …

Discrimination Of Automobile Carpet Fibers Using Multiple Analytical Techniques And The Subsequent Creation Of A Searchable Data
… of 98.02% was calculated. Only 55 of 2775 pairwise comparisons were indistinguishable. The information was subsequently entered into a searchable database for general public use.

Top Retailers in the United States: A Changing Landscape of Space Demand in a Post-COVID Era
… analyses, including macro research and pairwise comparisons of key financials and physical space metrics of 83 listed U.S. retail companies during a time period from 2017 to 2022. The research reveals a significant shifting of revenues towards e-commerce, and a substantial correlation …

A ranking experiment with paired comparisons and a factorial design
… which the data consist cf relative rankings in pairwise comparisons. Maximum likelihood estimates are developed for the ratings of the various levels of each factor und for the treatment combinations. Likelihood ratio tests of the most important hypotheses likely to arise are derived in detail. …

Clear aligner attachment removal techniques – an in vitro comparison of removal time residual composite, enamel surface characteristics, enamel loss, and material cost
… method was conducted to adjust for multiple comparisons. A p-value of less than 0.05 was considered statistically significant. Intra-rater reliability of residual composite and enamel surface characteristics scores were summarized using the intraclass correlation coefficient after a two-week …

Resilience among elementary educators as measured by the personal and organizational quality assessment-revised and the emotional quotient inventory: short
… statistics, one-way repeated measures ANOVA, and pairwise comparisons using Bonferroni correction were used to analyze data. All data were tested at the p<.05 level of significance. The null hypothesis that all time points would be similar on all indices was rejected for calmness and freedom of …

The Quicksort algorithm and related topics
… demonstration of the variance of the number of comparisons required, a known result but one whose detailed proof is not easy to read out of the literature. We also examine variants of Quicksort, where multiple pivots are chosen for the partitioning of the array. The rest of this work is …

Graduate admissions at MIT & comparison-based rank aggregation : a case study
… of an additional scoring system that is based on pairwise comparisons between applicants made by faculty reviewers. We present the design we created for this scheme and the code written to implement it, and analyze the data we obtained when the code went live during the 2012-2013 admissions cycle.
