The Similarity Measures for Linguistic q-Rung Orthopair Fuzzy Multi-Criteria Group Decision Making Using Projection Method

open access: yesIEEE Access, 2019
The linguistic q-rung orthopair fuzzy sets (Lq-ROFSs) can fully represent linguistic evaluation information by adjusting the parameter $q$ to describe the range of uncertain information.

Cosine similarity-based PageRank calculation

open access: yesInternational Journal of Web Science, 2011
This paper introduces a new method for calculating the rank of a web page based on the content similarity and the link structure. There are different ranking algorithms available in the literature to calculate the importance score of web pages. The basis of all ranking algorithms is the link structure of the web.

Cosine similarity-based adversarial process

open access: yesCoRR, 2019
An adversarial process between two deep neural networks is a promising approach to train a robust model. In this paper, we propose an adversarial process using cosine similarity, whereas conventional adversarial processes are based on inverted categorical cross entropy (CCE).

Cosine Similarity-Based Pruning for Concept Discovery [PDF]

open access: yes, 2016
In this work we focus on improving the time efficiency of Inductive Logic Programming (ILP)-based concept discovery systems. Such systems have scalability issues mainly due to the evaluation of large search spaces. Evaluation of the search space cosists translating candidate concept descriptor into SQL queries, which involve a number of equijoins on ...

The Document Vectors Using Cosine Similarity Revisited

open access: yesProceedings of the Third Workshop on Insights from Negative Results in NLP, 2022
The current state-of-the-art test accuracy (97.42\%) on the IMDB movie reviews dataset was reported by \citet{thongtan-phienthrakul-2019-sentiment} and achieved by the logistic regression classifier trained on the Document Vectors using Cosine Similarity (DV-ngrams-cosine) proposed in their paper and the Bag-of-N-grams (BON) vectors scaled by Naive ...

Textual Spatial Cosine Similarity

open access: yesCoRR, 2015
When dealing with document similarity many methods exist today, like cosine similarity. More complex methods are also available based on the semantic analysis of textual information, which are computationally expensive and rarely used in the real time feeding of content as in enterprise-wide search environments.
