Natural Language Processing R&D in Alibaba

Natural Language Processing (NLP) and related technologies are critical for the success of Internet business like e-commerce. Alibaba’s NLP R&D aims at supporting the business demands of Alibaba’s eco-system, creating new opportunities for Alibaba’s partners and advancing the state-of-the-art of NLP technologies. This talk will introduce our efforts to build NLP technique platform and machine translation (MT) platform that power Alibaba’s eco-system. Furthermore, some recent research work will be presented on product title compression with user-log information, sentiment classification with questions & answers, machine reading comprehension in real-world custom service, and cascade ranking for large-scale e-commerce search. The R&D work attracts hundreds of millions of users and generates significant business value every day.

The work attracts hundreds of millions of users and generates millions of revenue each day. Luo has published more than 150 journal and conference papers with substantial citations. His research has obtained many industry awards from Yahoo!, Google and Alibaba as well as NSF career award. Prior to joining Alibaba in 2014, he was an Associate Professor with Purdue University. He obtained degrees in computer science from Tsinghua University and Carnegie Mellon University.

Selected Topics in Deep Learning for Medical Image Analysis

To identify potential collaboration opportunities between TAAC members, this talk gives a brief review of Wang group’s current research efforts at UBC in the areas of Deep Learning for Medical Image Analysis. During the last few years, deep learning, in particular convolutional networks, has rapidly become popular for medical image analysis, including classification, object detection, segmentation, registration, and other tasks. This overview talk contains three major parts: (1) Skin image analysis, with focus on developing automated detection, segmentation, pattern recognition and computer-aided diagnosis based on skin vasculatures. Vascular structures seen in dermoscopy are of great clinical importance, playing an important role in skin cancer diagnosis, lesion growth and treatment monitoring. (2) 2D/3D medical image registration, with focus on accurate 2D/3D registration of pre-operative 3-D data and intra-operative 2-D X-ray images (which is a key enabler for image-guided therapy). We exploit the modeling power of Convolutional Neural Networks to significantly improve registration accuracy and efficiency. We further propose a Pairwise Domain Adaptation (PDA) module to adapt the model trained on source domain (i.e., synthetic data) to target domain (i.e., clinical data) by learning domain invariant features with a few paired real and synthetic data. (3) MRI data analytics, with focus on 3D CNN based automatic diagnosis of Attention Deficit Hyperactivity Disorder using functional and structural MRI data.

She has been Elected Member to several SPS TCs, including the Bio Imaging and Signal Processing TC, Multimedia SP TC, Machine Learning SP TC, and IFS TC. She was Associate Editor for the IEEE TSP, SPL, TMM, TIFS and TBME, and Area Editor of SPM. She is currently serving as Associate Editor for SPM and IEEE Transactions on Circuits and Systems-II: Express Briefs.

The Challenges of Running Neural Networks on Edge and Mobile Devices

Fast growth of the computation cost associated with training and testing of deep neural networks (DNNs) inspired various acceleration techniques for edge and mobile applications. Reducing topological complexity and simplifying data representation of neural networks are two approaches that popularly adopted in deep learning society: many connections in DNNs can be pruned and the precision of synaptic weights can be reduced, respectively, incurring no or minimum impact on inference accuracy. However, the practical impacts of hardware design are often ignored in these algorithm-level techniques, such as the increase of the random accesses to memory hierarchy and the constraints of memory capacity. On the other side, the limited understanding about the computational needs at algorithm level may lead to unrealistic assumptions during the hardware designs. In this talk, we will discuss this mismatch and show how we can solve it through an interactive design practice across both software and hardware levels.

He is a Fellow of IEEE.

Statistical Thinking for AI: Keeping Human in the Loop

Statistics plays a central role in the data science approach. In almost all data science solutions, data scientists need to exercise statistical thinking, in designing data collection, deriving insights from visualizing data, obtaining supporting evidence for data-based decisions and constructing models for predicting future trends from data. Recently developed artificial intelligence methods have shown to possess the power to identify patterns, extract knowledge, and generate prediction from complex data. Machine learning algorithms have been used to automate human tasks and support decision making. However, we soon realize that AI algorithms often produce biased and misleading results. In this talk, I will discuss the roots for these biases and present how statistical thinking can be used to introduce human wisdom and values into an AI workflow.
