Keynotes

The interaction of theory and practice in database research

by Ronald Fagin (IBM Research – Almaden)

Abstract :

The speaker will talk about applying theory to practice, with a focus on two IBM case studies.  In the first case study, the practitioner initiated the interaction. This interaction led to the following problem.  Assume that there is a set of “voters” and a set of “candidates”, where each voter assigns a numerical score to each candidate.  There is a scoring function (such as the mean or the median), and a consensus ranking is obtained by applying the scoring function to each candidate’s scores.  The problem is to find the top k candidates, while minimizing the number of database accesses. The speaker will present an algorithm that is optimal in an extremely strong sense:  not just in the worst case or the average case, but in every case!  Even though the algorithm is only 10 lines long (!), the paper containing the algorithm won the 2014 Gödel Prize, the top prize for a paper in theoretical computer science. The interaction in the second case study was initiated by theoreticians, who wanted to lay the foundations for “data exchange”, in which data is converted from one format to another. 

Although this problem may sound mundane, the issues that arise are fascinating, and this work made data exchange a new subfield, with special sessions in every major database conference.

This talk will be completely self-contained, and the speaker will derive morals from the case studies. The talk is aimed at both theoreticians and practitioners, to show them the mutual benefits of working together.

Querying Big Data: From Theory to Systems to Applications

by Wenfei Fan (BDBC, Beihang University; University of Edinburgh)

Abstract :

Querying big data is a departure from our familiar database techniques and even classical computational complexity theory. This talk advocates a resource-constrained paradigm, to query big data with bounded resources. Underlying the paradigm is a theory of bounded evaluation and a resource bounded approximation scheme. Following the paradigm, BEAS, a system for querying big relations with constrained resources, and GRAPE, a system for parallelizing sequential graph algorithms with guarantees on termination and correctness, are under development. As an application, we show how querying big data helps social media marketing, by proposing association rules for graphs.

Deep Learning Where to Go-The post deep learning age

by Bo Zhang(Tsinghua University)

Abstract :

Deep learning took us to a big data age which promotes the progress of artificial intelligence greatly. Due to its practicability and universality, some performances of image, speech and text processing based on deep learning are improved tremendously. Since deep learning is a black-box or brute-force learning method it only can discover the statistical correlations rather than causal relations, it is difficult to handle raw data effectively and its generalization ability is very low. In order to overcome these drawbacks, deep learning has to further learn from brain science. This is also the development direction of artificial intelligence in the post deep learning age.

The challenges of publishing databases

by Peter Buneman (University of Edinburgh)

Abstract :

Nearly all the information that is published on the Web uses some form of database technology. This information ranges from "born digital" scientific data -- such as images and sensor output -- to "human generated" data -- what we find in scholarly journals and on-line and reference works. Dealing with this information in any coherent way poses major challenges for computer science. For example, many organizations ask us to cite data in the same way that we traditionally cite scholarly articles, but how do we cite something that has been extracted by a query from a complex evolving database?

There are many other related challenges. Very few of these "publications" are static. How does one record the evolution of a database? When, as often happens, data is copied from one database to another, how does one record its provenance? There are also interesting social phenomena associated with the creation of these information artefacts. I shall attempt to give an account of the new database research issues associated with this form of publishing.

Managing data through the lens of an ontology

by Maurizio Lenzerini (Sapienza University)

Abstract :

Ontology-based data management is a new paradigm allowing managing data through the lens of a conceptualization of the domain of interest, called ontology. This new paradigm provides several interesting features, many of which have been already proved effective in managing complex information systems. On the other hand, several important issues remain open, and constitute stimulating challenges for the research community. In this talk we first provide an introduction to ontology-based data management, illustrating the main ideas and techniques for using an ontology to access the data layer of an information system, and then we discuss several important issues that are currently the subject of extensive investigations.

Transfer Learning for Reinforcement Learning

by Qiang Yang (Hong Kong University of Science and Technology)

Abstract :

Reinforcement learning is aiming at simulating human intelligent planning activities. However, the limitation of state space is the major bottleneck of achieving this objective. The development and the extensive application of deep learning promotes the organic combination of reinforcement learning with deep learning. Based on this development, transfer learning can be introduced to transfer the model, which is learnt by reinforcement learning from a large-scale dataset, based on a relatively small data set. This technique could deliver a personalized model for individual demands. In this talk, the basic principle of reinforced transfer learning and examples of application of the dialogue system will be discussed.

Chatting Robots by Deep Learning

by Ming Li (University of Waterloo, and RSVP Technologies Inc.)

Abstract :

Humans are different from the chimps because we talk. Making computers talk like a human is a dream of artificial intelligence. However, it is way more difficult than making it play Weiqi. A conversation needs to be natural, sensible, and robust. Template-based methods and keyword-based methods, as used in Echo or Siri, are either too restrictive or error-prone. We have partially resolved these problems and designed chatbotDoudou by a new deep learning architecture and a massive amount of data. Doudou significantly improves the state of the art, chatting naturally, wisely, knowledgeably, and robustly.

Towards Empathetic Human-Robot Interactions

by Pascale Fung (Hong Kong University of Science and Technology)

Abstract :

“Sorry I didn’t hear you” maybe the first empathetic utterance by acommercial machine. Since the late1990s when speech companies beganproviding their customer-service software to other numerous companies, which was programmed to use different phrases, people have gotten usedto speaking to machines. As people interact more often with voice andgesture controlled machines, they expect the machines to recognize different emotions, and understand other high level communicationfeatures such as humor, sarcasm and intention. In order to make suchcommunication possible, the machines need an empathy module in them,which is a software system that can extract emotions from human speech and behavior and can accordingly decide the correct response of therobot. Although research on empathetic robots is still in the primarystage, current methods involve using signal processing techniques,sentiment analysis and machine learning algorithms to make robots thatcan ’understand’ human emotion. Other aspects of human-robot interaction includefacial expression and gesture recognition; robot movement to convey emotion and intent.We propose Zara the Supergirl as aprototype system. It is a software based virtual android, with an animated cartoon character to present itself on the screen. Along the way it willget ’smarter’ and more empathetic, by having machine learningalgorithms, and gathering more data and learning from it. In this talk, I will give an overview of multi-channel recognition and expression of emotion and intent. I will present our work so far in the areas of deep learning of emotion and sentiment recognition, as well as humor recognition. I hope to explore thefuture direction of android development and how it can help improvepeople's lives.

Understanding Deep Learning and Neural Semantics

by Xiaogang Wang (Chinese University of Hong Kong)

Abstract :

Deep learning has achieved great success in computer vision. Many people believe that the success is due to employing a huge number of parameters to fit big training data. In this talk, I will show that neuron responses of deep models have clear semantic interpretation, which is supported by our research on multiple fields of face recognition, object tracking, human pose estimation, and crowd video analysis. In particular, the responses of neurons in the top layers have sparseness and strong selectiveness object classes, attributes and identities.  Sparseness and selectiveness are strongly correlated. Such selectiveness is naturally obtained through large scale training without adding extra regularization during the training process. By understanding neural semantics, we are inspired to develop new network architectures and training strategies and they effectively improve a broad range of applications in face recognition, face detection, compressing neural networks, object tracking, learned structured feature representation in human pose estimation, and effectively learning dynamic feature representations of different semantic units in video understanding.

Structural Information Theory: Principles for Distinguishing Order from Disorder

by Angsheng Li (Institute of Software, Chinese Academy of Sciences)

Abstract :

It has been a great challenge in computer science and information science to define the information embedded in physical systems that supports the distinction of the order from disorder. In 1953, Shannon himself asked the question to establish a structural theory of information that supports communication network analysis. The challenge had not been satisfactorily resolved, until recently we establish the first such a theory, structural information theory.  I will introduce our structural information theory.  Our theory supports communication network analysis, provides the principles for distinguishing the order from disorder in physical systems and for analyzing big data, provides the foundation for a theory of dynamical complexity of networks. Our theory establishes the principle for a next-generation search engine, leading to new directions in the network algorithm area.  I will also introduce some follow-up directions of our theory.

Simba: Towards Building Interactive Big Data Analytics Systems

by Feifei Li(University of Utah)

Abstract :

Interactive queries over large data becomes a critical requirement in many applications. As a result, it is critical to provide fast, scalable, and high-throughput query processing and analytics for numerous applications. We will present the Simba system that offers scalable and efficient in-memory spatial query processing and analytics for big spatial and multimedia data. Simba is based on Spark and runs over a cluster of commodity machines. In particular, Simba extends the Spark SQL engine to support rich spatial queries and analytics through both SQL and the Data Frame API. It introduces the concept and construction of indexes over RDDs in order to work with big spatial data and complex spatial operations. Lastly, Simba implements an effective query optimizer, which leverages its indexes and novel spatial-aware optimizations, to achieve both low latency and high throughput. Extensive experiments over large data sets demonstrate Simba's superior performance compared against other big data analytics system. Through its SQL and Data Frame API, Simba provides interactive analytics over big data, but when data grows too big and/or computation becomes too expensive, we will achieve interactive analytics through online analytics.

Big Learning with Bayesian Methods

by Jun Zhu (Tsinghua University)

Abstract :

Bayesian methods represent one important school of statistical methods for learning, inference and decision making. At the core is Bayes' theorem, which has been developed for more than 250 years. However, in the Big Data era, many challenges need to be addressed, ranging from theory, algorithm, and applications. In this talk, I will introduce some recent developments on generalizing Bayes' theorem to incorporate rich side information, which can be the large-margin property we like to impose on the model distribution, or the domain knowledge collected from experts or the crowds, and scalable online learning and distributed inference algorithms. The generic framework to do such tasks is called regularized Bayesian inference (RegBayes). I will introduce the basic ideas of RegBayes as well as several concrete examples with scalable inference algorithms and deep models.

DERF:Distinctive Efficient Robust Features from the Biological Modeling of the P Ganglion Cells

by Yunhong Wang (Beihang University)

Abstract :

Studies in neuroscience and biological vision have shown that the human retina has strong computational power, and its information representation supports vision tasks on both ventral and dorsal pathways. A new local image descriptor, termed Distinctive Efficient Robust Features, or DERF, is derived by modeling the response and distribution properties of the parvocellular-projecting ganglion cells (P-GCs) in the primate retina. DERF features exponential scale distribution, exponential grid structure, and circularly symmetric function Difference of Gaussian (DoG) used as a convolution kernel, all of which are consistent with the characteristics of the ganglion cell array found in neurophysiology, anatomy, and biophysics. In addition, a new explanation for local descriptor design is presented from the perspective of wavelet tight frames. DoG is naturally a wavelet, and the structure of the grid points array in our descriptor is closely related to the spatial sampling of wavelets. The DoG wavelet itself forms a frame, and when we modulate the parameters of our descriptor to make the frame tighter, the performance of the DERF descriptor improves accordingly. This is verified by designing a tight frame DoG (TF-DoG) which leads to much better performance. Extensive experiments conducted in the image matching task on the Multiview Stereo Correspondence Data set demonstrate that DERF outperforms state of the art methods for both hand-crafted and learned descriptors, while remaining robust and being much faster to compute.

Building Interactive Analytics From Ground Up : Architecture, Tradeoffs and a lot of Work

by Ning Xie(SmartSCT)

Abstract :

Businesses need analytics to help them make better decisions on their data.  Ideally, analytics would be interactive, visual, exploratory, and most importantly, so easy that a business user can use.  However, in recent times analytics had gone the opposite with the emergence of Big Data: complex algorithmic programming and dealing with heterogeneous data sources require expensive data scientists outside of the reach of many businesses.

In this talk, I will discuss how we build a commercial-quality interactive analytics platform from the ground-up to ease the complexities of Big Data.   I will share our architectural decisions and tradeoff considerations, from the service separation, to the connector data abstraction, rolling up to the engine planner/executor design and the front-end visualization.

Applying Big Data and Learning Techniques to Problems in Security

by Eric Hsu (KuangEn)

Abstract :

The engineering challenges presented by ever-growing data domains are well-appreciated, and have promoted the development of ever-improving algorithmic and implementational techniques for processing big data.  Meanwhile, when employing such data in machine learning, the traditional classification-oriented perspective has been that more data points make for an easier learning task.  How does this viewpoint change for a domain like security, where we want to isolate specific incidents like network intrusion (and thus are not in a purely unsupervised learning domain) and must prevent novel attacks in real time (and thus lack the labeled training examples characterizing a supervised domain)?  This talk will survey existing artificial intelligence approaches to securing large-scale systems, emphasizing an “anomaly detection” perspective where finding ways to model normalcy can be just as useful as modelling the malicious behaviours we wish to prevent.

Biography :

Before joining Kuang En to apply artificial intelligence techniques to the security domain, Eric Hsu has performed basic research in planning and scheduling at SRI International, and also built commercial machine learning systems for digital advertising startups that were later acquired by Yahoo and AOL.  After receiving an undergraduate degree at Harvard University, he completed his graduate studies at Stanford University and University of Toronto.  His general research interests involve the combination of discrete and continuous optimization techniques to solve applied problems in artificial intelligence.

Distributed Multi-Layer Indexing Scheme for Server-centric Cloud Storage System

by Xiaofeng Gao( Shanghai Jiao Tong University)

Abstract :

Cloud storage system poses new challenges to the community to support efficient concurrent querying tasks for various data-intensive applications, where indices always hold important positions. In this talk, we explore a practical method to construct a two-layer indexing scheme for multi-dimensional data in diverse server-centric cloud storage system. We first propose RT-HCN, an indexing scheme integrating.

R-tree based indexing structure and HCN-based routing protocol. RT-HCN organizes storage andcompute nodes into an HCN overlay, one of the newly proposed sever-centric data center topologies. Based on the properties of HCN, we design a specific index mapping technique to maintain layered global indices and corresponding query processing algorithms to support efficient query tasks. Then, we expand the idea of RT-HCN onto another server-centric data center topology DCell, discovering a potential generalized and feasible way of deploying two-layer indexing schemes on other server-centric networks. Furthermore, we prove theoretically that RT-HCN is both space-efficient and query-efficient, by which each node actually maintains a tolerable number of global indices while high concurrent queries can be processed within accepted overhead. We finallyconduct targeted experiments on Amazon’s EC2 platforms, comparing our design with RT-CAN, a similar indexing scheme for traditional P2P network. The results validate the query efficiency, especially the speedup of point query ofRT-HCN, depicting its potential applicability in future data centers.

Brain Quest: Perception-Guided Brain Network Comparison

by Lei Shi (Institute of Software, Chinese Academy of Science)

Abstract :

Why are some people more creative than others? How do human brain networks evolve over time? A key stepping stone to both mysteries and many more is to compare weighted brain networks. In contrast to networks arising from other application domains, the brain network exhibits its own characteristics (e.g., high density, indistinguishability), which makes any off-the-shelf data mining algorithm as well as visualization tool sub-optimal or even mis-leading. In this talk, we propose a shift from the current mining-then-visualization paradigm, to jointly model these two core building blocks (i.e., mining and visualization) for brain network comparisons. The key idea is to integrate the human perception constraint into the mining block earlier so as to guide the analysis process. We formulate this as a multi-objective feature selection problem; and propose and integrated framework, Brain Quest, to solve it. This talk will also discuss the integrated visual analytics pipeline that orchestrates computational models with comprehensive data visualizations on human brain networks. User studies, quantitative experiments, and two real-world case studies to evaluate the proposed method will be mentioned at last.

The Representation and Embedding of Knowledge Bases.

by Richong Zhang ( Beihang University)

Abstract :

The models developed to date for knowledge base embedding are all based on the assumption that the relations contained in knowledge bases are binary. For the training and testing of these embedding models, multi-fold (or n-ary) relational data are converted to triples (e.g., in FB15K dataset) and interpreted as instances of binary relations. However, this representation approach and data conversion is irreversible. We advocate a novel modeling framework, which models multi-fold relations directly using this canonical representation. Using this framework, the existing TransH model is generalized to a new model, m-TransH. The detailed framework setups and implementation algorithms will be delivered in this talk.

Spatio-temporal Crowdsourcing: A Novel Computation Paradigm in The Era of Sharing Economy

by Yongxin Tong ( Beihang University)

Abstract :

Crowdsourcing is a new computation paradigm where humans are enrolled actively to participate into the procedure of computing, especially for the tasks that are intrinsically easier for human than for computers. Recently, the rapid development of mobile Internet and Online-To-Offline (O2O) services has led to the boom of all types of spatio-temporal crowdsourcing platforms, where each user is treated as a mobile computing unit that can be activated and guided for certain tasks. In this talk, I will first briefly review the history of crowdsourcing and introduce some representative industrial applications of spatio-temporal crowdsourcing in the era of sharing economy, such as Uber, Didi Taxi, Gigwalk, etc. Then, I will discuss the core issues related to spatio-temporal crowdsourcing and introduce our recent research of real-time online task assignment. Finally, I also highlight some interesting future works regarding spatio-temporal crowdsourcing.
