Topic based object Influence analysis in Social networks
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 16 Số 4 - Trang 68-78 - 2013
In this article, we focus on researching models in social networks analysis and
use them to develop the system which enables users to exactly find topics as
well as necessary research of authors. In this research, we study Author –
Conference – Topic (ACT) model to find out the topic relevant to users’
requirements. With each of these topics, the system will create a graph of

ViMRC - VLSP 2021: Context-Aware Answer Extraction in Vietnamese Question Answering
VNU Journal of Science: Computer Science and Communication Engineering - Tập 38 Số 2 - 2022
MRC is challenging the natural language processing fields; machines
automatically have to answer questions based on specific passages for this task.
In recent years, machine reading comprehension (MRC) has received much
attention; many articles have been written about this task. However, most of
those articles only develop models in two main languages, English and Chinese.
In this article, we prop...
DIFFERENTIAL FORMULAS OF STOCHASTIC FUNCTIONS
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 12 Số 7 - Trang 29-34 - 2020
Based on the quadratic variation theorem of the Brownian motion, we have
established the basic rules of stochastic differetial calculus operations.
Theorem 1. If X,Y, are positive-valued stochastic processes satisfying
respectively the following stochastic differenntial equations Then a, b R: Where
Theorem 2 Suppose is the Hermite type stochastic process of then
STOCHASTIC CALCULUS WITH HERMITE TYPE PROCESSES
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 11 Số 6 - Trang 49-54 - 2021
Hermite type stochastic processes are the indespensable core resulting from the
well – matched couple of Wiener stochastic process and Hermite polynomials. They
will construct an orthogonal base of stochastic processses space. The paper
emphatically looks at bona fide nature of Ito integral and stochastic
differential equations compared with those of Hermite type stochastic processes.
Applying OLAP technology to support decision making in sales process
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 19 Số 2 - Trang 41-57 - 2016
OLAP (Online Analytical Processing) is a technology that enables the user to
easily and selectively extract and view data from different points of view. It
is also an important part of the decision system. This study proposes the
decisions in fulfillment process which could be supported by the OLAP
technology, including the quality of sales, the main product of the company, the
salary and the bonu...
A New Model for Discovering Communities of Users on Social Network
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 19 Số 1 - Trang 81-94 - 2016
The trend of technological development and increasing varieties of social media
lead to the changes in people’s behaviors in society and forming online
communities. Changes of human’s behaviors make many models of business,
marketing, services and even the field of education, security, politicsl change
from approaches to user management. Community of users on social networks
influence behaviors, h...
PREDICTING THE SUB-CLASS OF ENZYME BY APPLYING GRAPH MINING BASED ON SEQUENCE STRUCTURE OF ENZYME
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 11 Số 5 - Trang 44-49 - 2021
This article is a description of the way to apply graph mining technology to
disaggregate the amino acid sequence of the enzyme - belonging to the same
already named sub-class - into a set of respective maximal frequent subgraphs.
The subgraphs can have one or many vertexes. When predicting the sub-class of a
new enzyme, one just needs to disaggregate the amino acid sequence of that
enzyme, then m...
A Modified Semi-parametric Regression Model For Flood Forecasting
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 18 Số 2 - Trang 95-105 - 2015
In recent years, inundation, one of natural calamities, occurs frequently and
fiercely. We are sustained severe losses in the floods every year. Therefore,
the development of control methods to determine, analyze, model and predict the
floods is indispensable and urgent. In this paper, we propose a justified
semiparametric regression model for flood water levels forecasting. The new
model has thre...
ViMRC - VLSP 2021: Using XLM-RoBERTa and Filter Output for Vietnamese Machine Reading Comprehension
VNU Journal of Science: Computer Science and Communication Engineering - Tập 37 Số 1 - 2022
Machine Reading Comprehension (MRC) has recently made significant progress. This
paper is the result of our participation in building an MRC system specifically
for Vietnamese on Vietnamese Machine Reading Comprehension at the 8th
International Workshop on Vietnamese Language and Speech Processing (VLSP 2021).
Based on SQuAD2.0, the organizing committee developed the Vietnamese Question
Answering ...
An empirical evaluation of feature extraction for Vietnamese fruit classification
Vietnam Journal of Science and Technology - Tập 60 Số 5 - 2022
In recent years, Vietnamese fruit production has marked significant progress in
terms of scale and product structure. Viet Nam enjoys suitable climates for
tropic, subtropical fruits, and some temperate fruits. Thanks to the diversified
ecology, implementing an automatic classification system has received a
significant concern. In this paper, we address the problem of Vietnamese fruit
classificati...
