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 …

Pairwise embedding for event coreference resolution
Event coreference resolution is an important part in information extraction research and natural language understanding areas. Recently, the pre-trained language models emerging in modern Natural Language Processing (NLP) community provide a new perspective of solving classical NLP tasks. This …

Insights into microbial community structure from pairwise interaction networks
… First, we investigate the network of pairwise competitive interactions in a model community consisting of 20 strains of naturally co-occurring soil bacteria. The resulting interaction network is strongly hierarchical and lacks significant non-transitive motifs, a result that is robust …

Pairwise Matching of Intermediate Representations for Fine-grained Explainability
… to generate fine-grained, highly-localized pairwise visual explanations. We use animal and building re-identification (re-ID) as a primary case study of our method, and we demonstrate qualitatively improved results over a diverse set of explainability baselines on 35 public re-ID datasets. …

Cooperative strategies for pairwise secure communication channels in sensor networks
… one method that enables sensors to establish pairwise secure communication channels. This strategy relies on a cooperative set of peer sensors to construct a unique key between two sensors. We built a unique network simulator to test secure communication parameters in a typical deployment …

A distributed CPU-GPU framework for large-scale pairwise alignment
… biology require the all-against-all pairwise comparisons of tens of thousands of individual biological sequences. Each such comparison can be performed with the well-known Needleman-Wunsch alignment algorithm. However, with the rapid growth of biological databases, performing all …

MCDM methods based on pairwise comparison matrices and their fuzzy extension
Methods based on pairwise comparison matrices (PCMs) form a significant part of multi-criteria decision making (MCDM) methods. These methods are based on structuring pairwise comparisons (PCs) of objects from a finite set of objects into a PCM and deriving priorities of objects that represent the …

A Pairwise Feature Selection Method For Gene Data Using Information Gain
The current technical practice for doing classification has limitations when using gene expression microarray data. For example, the robustness of top scoring pairs does not extend to some datasets involving small data size and the gene set with best discrimination power may not be involve a …

Exploiting Multigrain Parallelism in Pairwise Sequence Search on Emergent CMP Architectures
With the emerging hybrid multi-core and many-core compute platforms delivering unprecedented high performance within a single chip, and making rapid strides toward the commodity processor market, they are widely expected to replace the multi-core processors in the existing High-Performance …

Freshwater Mussels Vary in Substrate Preference and Mobility in Pairwise Behavioral Experiments
Freshwater mussels are a highly imperiled group of organisms that are sensitive to environmental stressors such as drought, flooding events, and global warming. While most mussels are considered to have broad sediment tolerances, some species are micro-habitat specialists. Mussel mobility can vary …

Finding functional groups of genes using pairwise relational data : methods and applications
… can hence deliver candidate gene modules. Pairwise similarity measures derived from these profiles are used as input to the popular hierarchical agglomerative clustering algorithms; however, these algorithms offer little guidance on how to choose candidate modules and how to improve a …

Point cloud alignment in arm reconstruction for lymphedema detection by iterating pairwise ICP
Arm lymphedema is a debilitating condition characterized by a large swelling of the patient arms. This thesis describes a system for measuring arm volume with the goal of providing a cost-effective, reliable, easy to use, comfortable, and informative alternative to the tedious water displacement …

Páros összehasonlítás mátrixok a többszempontú döntéselméletben = Pairwise Comparison Matrices in Multi-Criteria Decision Making
Döntési helyzetekben általában a legjobb alternatíva kiválasztása, vagy az alternatívák rangsorolása a cél. Ez többszempontú döntési feladatokban különösen nehézzé válhat, hiszen itt általában nincsen olyan alternatíva, amely minden szempont szerint a legjobb. A szempontok súlyozásával és az …

A Graph Neural Network for pairwise surrogate modeling in population-based algorithms with tournament selection
… In this study, we have proposed a novel pairwise surrogate model to identify the superiority between candidate solutions in a pairwise comparison. We demonstrated a Graph Neural Network (GNN) to be trained on number of pairs, then utilized to compare a pair of candidate solutions. To …
