Picture fuzzy sets Tập 30 Số 4 - Trang 409 - 2015
Bùi Công Cường
In this paper, we introduce the concept of picture fuzzy sets (PFS), which are direct extensions of the fuzzy sets and the intuitonistic fuzzy sets. Then some operations on PFS with some properties are considered. The following sections are devoted to the Zadeh Extension Principle, picture fuzzy relations and picture fuzzy soft sets. Here, the basic preliminaries of PFS theory are presented.

Sentiment analysis is a natural language processing (NLP) task of identifying orextracting the sentiment content of a text unit. This task has become an active research topic since the early 2000s. During the two last editions of the VLSP workshop series, the shared task on Sentiment Analysis (SA) for Vietnamese has been organized in order to provide an objective evaluation measurement about the p...... hiện toàn bộ

Rough picture fuzzy set and picture fuzzy topologies Tập 31 Số 3 - Trang 245 - 2015
Nguyễn Xuân Thảo, Nguyễn Văn Định
Approximation of a picture fuzzy set on a crisp approximation space gives a rough picture fuzzy set. In this paper, the concept of a rough picture set is introduced, besides, we also investigate some topological structures of a rough picture fuzzy set are investigated, such are lower and upper rough picture fuzzy approximation operators.

THEORETICAL ANALYSIS OF PICTURE FUZZY CLUSTERING: CONVERGENCE AND PROPERTY Tập 34 Số 1 - Trang 17--32 - 2018
Pham Thi Minh Phuong, Pham Huy Thong, Le Hoang Son
Recently, picture fuzzy clustering (FC-PFS) has been introduced as a new computational intelligence tool for various problems in knowledge discovery and pattern recognition. However, an important question that was lacked in the related researches is examination of mathematical properties behind the picture fuzzy clustering algorithm such as the convergence, the boundary or the convergence rate, et...... hiện toàn bộ

NEW DISSIMILARITY MEASURES ON PICTURE FUZZY SETS AND APPLICATIONS Tập 34 Số 3 - Trang 219--231 - 2018
Nhung Thi Le, Dinh Van Nguyen, Chau Minh Ngoc, Thao Xuan Nguyen
The dissimilarity measures between fuzzy sets/intuitionistic fuzzy sets/picture fuzzy sets are studied and applied in various matters. In this paper, we propose some new dissimilarity measures on picture fuzzy sets. This new dissimilarity measures overcome the restrictions of all existing dissimilarity measures on picture fuzzy sets. After that, we apply these new measures to the pattern recogniti...... hiện toàn bộ

NASH EQUILIBRIUM MODEL FOR CONFLICTS IN PROJECT MANAGEMENT Tập 35 Số 2 - Trang 167--184 - 2019
Thang Quyet Huynh, Ngoc Bao Trinh, Thang Xuan Nguyen
There are many types of concern to project management, we used to deal with them using Risk management activities. But in the complicated situation, there are many factors and preconditions of the issues that make the issues be unrecognizable with risk consultants, and the consequences of these issues getting more and more enormous. The cause of issues can be a conflict between the project teams a...... hiện toàn bộ

Factorization forecasting approach for user modeling Tập 31 Số 2 - Trang 133-148 - 2015
Nguyễn Thái Nghe, Lars Schmidt-Thieme
User modeling is a task which customizes and adapts the systems to meet users' specific needs. The user modeling is widely used in many areas. For example, in e-commerce, it is used for modeling consumers' preferences (behaviors) then predicting their future preferences to recommend suitable products to them. In e-learning (e.g., intelligent tutoring systems - ITS), the user modeling is used to m...... hiện toàn bộ

ENROLLMENT FORECASTING BASED ON LINGUISTIC TIME SERIES Tập 36 Số 2 - Trang 119--137 - 2020
Nguyen Duy Hieu, Nguyen Cat Ho, Vu Nhu Lan
Dealing with the time series forecasting problem attracts much attention from the fuzzy community. Many models and methods have been proposed in the literature since the publication of the study by Song and Chissom in 1993, in which they proposed fuzzy time series together with its fuzzy forecasting model for time series data and the fuzzy formalism to handle their uncertainty. Unfortunately, the ...... hiện toàn bộ
