VLSP SHARED TASK: SENTIMENT ANALYSIS
Tập 34 Số 4 - Trang 295--310 - 2019
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...

Rough picture fuzzy set and picture fuzzy topologies
Tập 31 Số 3 - Trang 245 - 2015
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
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...

NASH EQUILIBRIUM MODEL FOR CONFLICTS IN PROJECT MANAGEMENT
Tập 35 Số 2 - Trang 167--184 - 2019
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...

SLIDING MODE CONTROL FOR PARALLEL ROBOTS DRIVEN BY ELECTRIC MOTORS IN TASK SPACE
Tập 33 Số 4 - Trang 325--337 - 2018
This paper addresses the modelling of parallel robots including electric
actuators. The dynamic model of the system is derived by applying the
substructure method and Lagrangian equations with multipliers in form of
redundant generalized coordinates. These equations are then transformed to the
form of minimal coordinates of operational variables. Based on this form a
sliding mode controller is des...

Some New De Morgan Picture Operator Triples in Picture Fuzzy Logic
Tập 33 Số 2 - Trang 143--164 - 2018
A new concept of picture fuzzy sets (PFS) were introduced in 2013, which are
directextensions of the fuzzy sets and the intuitonistic fuzzy sets. Then some
operations on PFS withsome properties are considered in [ 9,10 ]. Some basic
operators of fuzzy logic as negation, tnorms, t-conorms for picture fuzzy sets
firstly are defined and studied in [13,14]. This paper isdevoted to some classes
of repr...

Adapt-TTS: High-quality zero-shot multi-speaker text-to-speech adaptive-based for Vietnamese
Tập 39 Số 2 - Trang 159--173 - 2023
Current adaptive-based speech synthesis techniques are based on two main
streams: 1. Fine-tuning the model using small amounts of adaptive data, and 2.
Conditionally training the entire model through a speaker embedding of the
target speaker. However, both of these methods require adaptive data to appear
during training, which makes the training cost to generate new voices quite
expensively. In ad...

HUPSMT: AN EFFICIENT ALGORITHM FOR MINING HIGH UTILITY-PROBABILITY SEQUENCES IN UNCERTAIN DATABASES WITH MULTIPLE MINIMUM UTILITY THRESHOLDS
Tập 35 Số 1 - Trang 1--20 - 2019
The problem of high utility sequence mining (HUSM) in quantitative se-quence
databases (QSDBs) is more general than that of frequent sequence mining in
se-quence databases. An important limitation of HUSM is that a user-predened
minimum tility threshold is used commonly to decide if a sequence is high
utility. However, this is not convincing in many real-life applications as
sequences may have dif...
