AttriRank: the state-of-the-art model for unsupervised ranking

AttriRank: the state-of-the-art model for unsupervised ranking

Node ranking in a graph is an important technique underlying many real-world applications. Take web search for example. This task is essential for returning important (or highly ranked) websites that are relevant to a query. Because the entire Internet with all of its webpages and hyperlinks forms a graph, a technique that ranks nodes in a graph becomes essential for this application. Such a ranking technique would also be useful in identifying influential persons or opinion leaders in a large s...

Deep learning for malicious encrypted traffic detection

Deep learning for malicious encrypted traffic detection

The use of encrypted traffic on the Internet has become increasingly popular in recent years. Google and the Mozilla Foundation have released statistical data indicating that more than half of their browser users used HTTPS protocol-encrypted connections in 2016. Encrypted network traffic may conceal malicious software connections and hacker attack activities. According to Cisco’s reports, malicious software that communicates via TLS-encrypted connections accounted for 2.21% in 2015, where...

Can a machine learn human language without human teaching by means of a generative adversarial network?

Can a machine learn human language without human teaching by means of a generative adversarial network?

Human infants acquire language with little formal teaching, but machines need large amounts of annotated data, which makes the development of natural language processing technology challenging. Although deep learning has already had tremendous success in natural language processing, the training is usually supervised. Only large companies can collect large amounts of labeled data to build high-quality automatic speech recognition (ASR) systems and then build systems that understand spoken langua...

Dependency structure matrix genetic algorithm II

Dependency structure matrix genetic algorithm II

Introduction In 2015, we proposed the dependency structure matrix genetic algorithm II (DSMGA-II) [1], which is currently a state-of-the-art discrete genetic algorithm. Based on the dependency structure matrix (DSM), a new linkage model called the incremental linkage set (ILS) is adopted in DSMGA-II to provide potential models for mixing. Restricted mixing and back mixing are the major recombination operators of DSMGA-II. Such a combination significantly reduces the number of function evaluat...

IdenNet:Facial Action Unit Detection Using Identity Normalization

IdenNet:Facial Action Unit Detection Using Identity Normalization

Facial action unit (AU) detection is an important task that enables emotion recognition from facial movements. Figure 1 shows a few AU examples that illustrate the advanced ability to decently describe facial expressions across primary categories such as neutral, happy, and sad. Prof. Hsu’s team is motivated to conduct this research to improve the social ability of robots when interacting with humans. To that end, the team proposes a novel algorithm using identity normalization to address ...

Video summarization through action localization on a social robot

Video summarization through action localization on a social robot

Using a robot to help family members look after seniors living alone With a large portion of Taiwan’s population becoming aged, Dr. Yang aims to investigate the feasibility of applying video summarization techniques using a social robot to help family members look after seniors living alone. The setting is a home where an elderly person lives alone, whose family members are willing to care for the person but too busy to assist every day. A household robot will help if it can follow the ...

Designing for complex creative task solving

Designing for complex creative task solving

Solving creative problems such as those pertaining to writing or design is challenging because such problems are open-ended and require people to spend much time and effort to achieve high-quality results through trial and error. Feedback plays a critical role in this process because it can help people recognize and fix errors, leading to better results. However, high-quality feedback is difficult to obtain due to the limited pool of experts available. To address the issues of scalability and hi...

An AI Discussion with an AI Pioneer in Taiwan

An AI Discussion with an AI Pioneer in Taiwan

The Interview:Dr. Li-Chen Fu Artificial intelligence (AI) is currently one of the most important topics among both industries and individuals. The main question is: How will the AI trend impact people, industries and the next generation, and what opportunities might it bring in the next 30 years? We are all eager to know. Today, our guest is Dr. Li-Chen Fu, Distinguished Professor at the Department of Electrical Engineering and Computer Science, National Taiwan University, former President of...

Going to court:The transformation of judicial consciousness in Taiwan under Japanese rule

Going to court:The transformation of judicial consciousness in Taiwan under Japanese rule

With the advent of the influence of Western powers in East Asia, Taiwan encountered its first exposure to law derived from the modern West (hereafter “modern law”) when the island was ceded to the prewar Japanese Empire by Qing China under the Treaty of Shimonoseki in 1895. The Taiwanese people, who were composed of Han Chinese immigrants and indigenous peoples who had been partly assimilated by those Chinese immigrants, then had access to a modern/Western court system that was creat...

Cross-sector partnerships in community governance at the district level:A case study of the welfare and healthcare service promotion campaign in Beitou District, Taipei

Cross-sector partnerships in community governance at the district level:A case study of the welfare and healthcare service promotion campaign in Beitou District, Taipei

This study examines the welfare and healthcare service promotion campaign in Beitou District, Taipei, focusing on participatory networks and cross-sector partnerships in community governance at the district level. There are three emphases in this article: a discussion of theories and practices relevant to community governance; an analysis of interactions in governance networks for communities in Beitou; and an examination of the characteristics and problems of community governance at the distric...
