BAMB
ACM Transactions on Intelligent Systems and Technology - Tập 10 Số 5 - Trang 1-25 - 2019
Hao Wang, Kui Yu, Hao Wang, Lin Liu, Wei Ding, Xindong Wu
The discovery of Markov blanket (MB) for feature selection has attracted much attention in recent years, since the MB of the class attribute is the optimal feature subset for feature selection. However, almost all existing MB discovery algorithms focus on either improving computational efficiency or boosting learning accuracy, instead of both. In this article, we propose a novel MB discovery algor... hiện toàn bộ
FastRx: Exploring Fastformer and Memory-Augmented Graph Neural Networks for Personalized Medication Recommendations
ACM Transactions on Intelligent Systems and Technology -
Tai Tan Phan, Ling Chen, Chun-Hung Chen, Wen-Chih Peng
Personalized medication recommendations aim to suggest a set of medications based on the clinical conditions of a patient. Not only should the patient's diagnosis, procedure, and medication history be considered, but drug-drug interactions (DDIs) must also be taken into account to prevent adverse drug reactions. Although recent studies on medication recommendation have considered DDIs and patient ... hiện toàn bộ
LIBSVM
ACM Transactions on Intelligent Systems and Technology - Tập 2 Số 3 - Trang 1-27 - 2011
Chih-Chung Chang, Chih‐Jen Lin
LIBSVM is a library for Support Vector Machines (SVMs). We have been actively developing this package since the year 2000. The goal is to help users to easily apply SVM to their applications. LIBSVM has gained wide popularity in machine learning and many other areas. In this article, we present all implementation details of LIBSVM. Issues such as solving SVM optimization problems theoretical conve... hiện toàn bộ
Mining Travel Patterns from Geotagged Photos
ACM Transactions on Intelligent Systems and Technology - Tập 3 Số 3 - Trang 1-18 - 2012
Yan-Tao Zheng, Zheng-Jun Zha, Tat‐Seng Chua
Recently, the phenomenal advent of photo-sharing services, such as Flickr and Panoramio, have led to volumous community-contributed photos with text tags, timestamps, and geographic references on the Internet. The photos, together with their time- and geo-references, become the digital footprints of photo takers and implicitly document their spatiotemporal movements. This study aims to leverage th... hiện toàn bộ
Self-weighted Robust LDA for Multiclass Classification with Edge Classes
ACM Transactions on Intelligent Systems and Technology - Tập 12 Số 1 - Trang 1-19 - 2021
Caixia Yan, Xiaojun Chang, Minnan Luo, Qinghua Zheng, Xiaoqin Zhang, Zhihui Li, Feiping Nie
Linear discriminant analysis (LDA) is a popular technique to learn the most discriminative features for multi-class classification. A vast majority of existing LDA algorithms are prone to be dominated by the class with very large deviation from the others, i.e., edge class, which occurs frequently in multi-class classification. First, the existence of edge classes often makes the total mean biased... hiện toàn bộ
Traffic Information Publication with Privacy Preservation
ACM Transactions on Intelligent Systems and Technology - Tập 5 Số 3 - Trang 1-26 - 2014
Sashi Gurung, Dan Lin, Wei Jiang, Ali R. Hurson, Rui Zhang
We are experiencing the expanding use of location-based services such as AT&T’s TeleNav GPS Navigator and Intel’s Thing Finder. Existing location-based services have collected a large amount of location data, which has great potential for statistical usage in applications like traffic flow analysis, infrastructure planning, and advertisement dissemination. The key challenge is how to wisely use th... hiện toàn bộ
Extracting City Traffic Events from Social Streams
ACM Transactions on Intelligent Systems and Technology - Tập 6 Số 4 - Trang 1-27 - 2015
Pramod Anantharam, Payam Barnaghi, Krishnaprasad Thirunarayan, Amit Sheth
Cities are composed of complex systems with physical, cyber, and social components. Current works on extracting and understanding city events mainly rely on technology-enabled infrastructure to observe and record events. In this work, we propose an approach to leverage citizen observations of various city systems and services, such as traffic, public transport, water supply, weather, sewage, and p... hiện toàn bộ
