Editor of HKIE Transactions. His current research interests include human
face recognition, image and video processing, and computer vision.
Abstract: A lot of research on face recognition has been conducted over the past two decades or more. Various face recognition methods have been proposed, but investigations are still underway to tackle different problems and challenges for face recognition. The existing algorithms can only solve some of the problems, and their performances degrade in real-world applications. In this speech, we will first discuss the performances of face recognition techniques on face images at different resolutions. Then, we will focus on the issues and methods for low-resolution face recognition. For low-resolution face recognition, we will present different approaches, and focus more on the approach based on feature super-resolution and fusion. Furthermore, the use of deep learning for face recognition will also be presented and discussed.

Abstract: In natural language processing (NLP), language model is doubtlessly an intrinsic element, as it plays a fundamental role in many conventional NLP tasks, e.g., speech recognition to image captioning etc. Therefore, learning an exceptional language model usually enhance the hidden aspects or metrics; forging its pivotal role in NLP. Language models are gaining popularity as of the abundance of online texts, comments and reviews. Due to the advancement of e-commerce, people do write their reviews about the products they have received. In crowdfunding sites, comments are so critical that negative reviews can damage the reputation of the product’s creator or can affect the buying of others. Life is too fast these days that people find it difficult to go through abundant of text data to take a decision. Therefore, topic discovery is quite valuable in various aspects as of saving time of the user, providing the summary of text in form of discussion topics, and providing contextual information etc. Topic models are being studied for decades and are of fundamental importance as these models act as a tool in order to infer the latent topics and extracting semantic structure of a document. In this speech, we have used the Latent Topic Model (LDA) in order to generate topics for crowdfunding comments. Our proposed model is recurrent neural network (RNN) based language model, which uses the latent topics generated by LDA, is constructed to extract the comprehensive semantic meaning related words in comments. Moreover, this combined approach is of better capability on creating topic clusters then traditional ones, which signifies that blending the information from deep learning and topic modeling is a substantial way to generate an improved understanding of crowdfunding comments.

Abstract: Ambient backscatter (AmBack) has emerged as a promising technology
for various communication and Internet of Things (IoT) applications due to
the recent advances in the hardware implementation. In contrast to
traditional wireless systems, no carrier generation and power supply are
needed for AmBack, and the dedicated reader and round-trip path loss can be
avoided compared to the radio frequency identification (RFID) technology. In
this talk, we begin with the fundamentals of AmBack, and then highlights
several interesting topics in signal transmission schemes including
frequency division multiple access (FDMA)-based interference free
transmission, hybrid active and passive transmission, and opportunistic
AmBack-assisted relay transmission.
