Grey relational analysis and natural language Processing
This paper investigates validity of using grey relational analysis (GRA) for natural language processing (NLP). The domain of NLP is one associated with inherent vagueness and abstraction, with many sub-domains all invoking ...
Relation between China’s gasoline prices and international crude oil prices
(Taylor & Francis, 2016-12-07)
China’s gasoline prices are still regulated by government although China's refined oil pricing mechanism has been reformed for many times. In this paper, proximity and similarity between China’s gasoline prices and Brent ...
Using fractional order method to generalize strengthening generating operator buffer operator and weakening buffer operator
Traditional integer order buffer operator is extended to fractional order buffer operator, the corresponding relationship between the weakening buffer operator and the strengthening buffer operator is revealed. Fractional ...
Grey double exponential smoothing model and its application on pig price forecasting
To resolve the conﬂict between our desire for a good smoothing eﬀect and desire to give additional weight to the recent change, a grey accumulating generation operator that can smooth the random interference of data is ...
Natural language processing - A Prolog perspective.
A prediction method for plasma concentration by using a nonlinear grey Bernoulli combined model based on a self-memory algorithm
The goal of this work is to present and explore the application of a novel nonlinear grey Bernoulli combined model based on a self-memory algorithm, abbreviated as SA-NGBM, for modeling single-peaked sequences of time ...
A summary of the progress in grey system research
Quantification of R-fuzzy sets
The main aim of this paper is to connect R-fuzzy sets and type-2 fuzzy sets, so as to provide a practical means to express complex uncertainty without the associated difficulty of a type-2 fuzzy set. The paper puts forward ...
Quantification of Perception Clusters Using R-Fuzzy Sets and Grey Analysis
This paper investigates the use of the R-fuzzy significance measure hybrid approach introduced by the authors in a previous work; used in conjunction with grey analysis to allow for further inferencing, providing a higher ...
Proximity and Similitude of Sequences Based on Grey Relational Analysis
(Research Information Ltd, 2014)
Time series analysis, the most popular method, is facing some challenges, including small sample, non-stable relation, stochastic distribution constraint, and so on. Grey relational analysis can supply some new ideas for ...
