SUMMARY:Application of Structure Descriptor for Rational Design of Transition Metal Catalysts
DESCRIPTION:Instructors/Speakers\nProf. Daojian CHENG\nProfessor of Department of Chemical Engineering\nBeijing University of Chemical and Technology\nChina \nAbstract\nIn this talk\, Prof. Cheng will present an overview of some exciting results from our recently proposed structure descriptor\, mapping the quantitative relationship between intrinsic structural feature and catalytic performance for transition metal catalysis\, as well as its application in the high-throughput screening on catalyst and rational construction of catalytic sites. The central concept of our structure descriptor contains following points: (1) The features parameters inside structure descriptor have to be unique in representing electronic and geometric structures of a catalytic site. (2) The features parameters inside structure descriptor must be easily computed\, experimentally quantified or readily available physical properties from databases\, which is conveniently used for rapid screening. (3) Most importantly\, structure descriptor should be physically intuitive to ensure model robustness and direct inference of chemical insights\, the variation of which is unambiguously linked to changes in adsorption energies or catalytic activity. With the constructed structure descriptor for each transition metal catalyst system\, such as single-atom catalyst\, nanocluster\, alloy and so on\, it is helpful for fundamental understanding of structure–activity relationships between catalytic activity and the physical properties of transition metal catalysts\, which is validated by available experimental data. \nBiography\nProf. Daojian Cheng is currently a professor at Department of Chemical Engineering\, Beijing University of Chemical Technology\, China. He obtained his Ph.D. Degree in Chemical Engineering from Beijing University of Chemical Technology in 2008. During 2008-2010\, he worked as a Postdoctoral Research Fellow at Université Libre de Bruxelles\, Belgium. Currently he has interests in theoretical study\, computational design and experimental synthesis of metal clusters and nanoalloys as catalysts for renewable clean energy and environmental protection applications. He is author of roughly 120 journal articles. He has been named a Fellow of the Royal Society of Chemistry in 2016 and obtained National Natural Science Foundation of China–Outstanding Youth Foundation in 2018. \n

SUMMARY:Bug Detection and Execution Replay for Concurrent Software Systems
DESCRIPTION:Instructors/Speakers\nProf. Zijiang YANG\nWestern Michigan University\nUnited States \nAbstract\nBugs in concurrent software systems are very difficult to detect and replay. This is due to the complexity of the software itself and the non-determinism of concurrency. To detect data races\, the major source of concurrent bugs\, we present a new approach to sample memory accesses across two threads and executions as a data race involves two threads and a program under testing is repeatedly executed. To detect deadlocks\, we interestingly observe that every two events of a deadlock usually occur within a short range called bug radius. Based on bug radius we present an approach to select priority change points within the bug radius that guarantees larger probabilities to trigger deadlocks. Finally\, we present a processor-based record-and-replay solution that does not require detecting and logging shared-memory dependencies to enable multi-processor execution replay. Shared-memory dependencies between threads are reconstructed offline\, during replay\, using an algorithm based on an SMT solver. \nBiography\nZijiang James Yang is the founder of GuardStrike Inc\, a company that focuses on providing tools and services for the quality and security of emerging software systems. Yang is also a professor at Western Michigan University. His research is in the broad areas of software engineering and formal methods. He has published over eighty conference and journal papers. He is also an inventor of ten United States patents. Yang received his Ph.D. from the University of Pennsylvania\, M.S. from Rice University\, and B.S. from the University of Science and Technology of China\, all in computer science. He was a recipient of the award and the 2008 CEAS outstanding new researcher award. He was a visi2018 ACM SIGSOFT Distinguished Paper Award\, 2015 CEAS outstanding researcher award\, 2010 PADTAD best paper award\, 2008 ACM TODAES best paper ting professor at EECS\, University of Michigan from 2009 to 2013. He is the general chair of the 12th IEEE Conference on Software Testing\, Validation and Verification (ICST). \n

SUMMARY:Extrapolation multigrid methods for solving large linear system arising from the discretizations of PDEs
DESCRIPTION:Instructors/Speakers\nProf. Kejia PAN\nProfessor\nSchool of Mathematics and Statistics\nCentral South University\nChina \nAbstract\nThe multigrid method is an efficient iterative method for solving discrete partial differential equations. The geometric multigrid method has the nested mesh required for Richardson extrapolation. We propose two extrapolation multigrid methods: extrapolation cascadic multigrid method (EXCMG)\, extrapolation full multigrid method (EXFMG)\, and show the superoptimality of the EXCMG method for solving second-order elliptic problems. Finally\, some numerical experiments include second-order and fourth-order elliptic problems and fractional diffusion equations are given to show the efficiency of the EXCMG method. \nBiography\nProf. Pan is a professor and the vice dean of School of Mathematics and Statistics\, Central South University\, China. He got his PhD degree in Fudan University in 2009. His research area include multigrid method\, finite difference method for solving nonlinear PDEs\, and finite element methods. \n

SUMMARY:Extremely Low Order Explosive Models from Combustion Process
DESCRIPTION:Instructors/Speakers\nProf. Yufeng XU\nAssociate Professor\nSchool of Mathematics and Statistics\nCentral South University\nChina \nAbstract\nIn this talk\, we will review some explosive models from combustion theory. These models do not satisfy global Lipschitz condition in general\, therefore nonexistence or multiplicity of classic solution are of extensive interests. We shall study a class of generalized explosive model with extremely low order temporal fractional derivative. Blowup phenomenon is theoretically analyzed and numerical simulation is carried out via a mixed numerical method based on adaptive finite difference and discontinuous Galerkin method. It is shown that the size of spatial domain cannot be too small\, for guaranteeing the appearance of explosion of solution\, which coincides with the physical observation. \nBiography\nProf. Xu is an associate professor of School of Mathematics and Statistics\, Central South University\, China. He got his PhD degree in Central South University in 2014. His research area include finite difference method and finite element methods for solving nonlinear fractional PDEs. \n

SUMMARY:CN-WSGD schemes and CN-EWSGD schemes for space-fractional advection-diffusion equations
DESCRIPTION:Instructors/Speakers\nProf. Furong LIN\nProfessor\nDepartment of Mathematics\nShantou University\nChina \nAbstract\nWe consider high order finite difference schemes for one-dimensional space-fractional advection-diffusion equation (SFADE). The temporal derivative is approximated by the Crank-Nicolson (CN) scheme and the space fractional derivatives are approximated by the weighted and shifted Gr\”{u}nwald difference (WSGD) scheme. In general WSGD schemes have second order accuracy\, and by selecting a special parameter\, we get the third order accuracy scheme. However\, the third order scheme may not be stable. In this talk\, some results on the accuracy and the stability of CN-WSGD schemes are reported. \nBiography\nProf. Lin is a professor of Department of Mathematics\, Shantou University\, China. He got his PhD degree in Hong Kong University in 1995. His research area include numerical linear algebra\, fast algorithms for Toeplitz matrix\, numerical methods for PDEs. \n

SUMMARY:Learning to Build a New Reality
DESCRIPTION:Instructors/Speakers\nProf. Jingyi YU\nShanghaiTech University\nChina \nAbstract\nThere have been tremendous advances on applying deep learning techniques for 2d image understanding. In contrast\, very little work has focused on employing deep learning for modeling datasets beyond 2D such as 3D geometry and 4D light fields. In this talk\, I present several latest works from our group on in this exciting new arena\, with a focus on their applications to virtual and augmented reality and computational photography. I first present a novel deep surface light field (DSLF) technique. A surface light field represents the radiance of rays originating from any points on the surface in any directions. Traditional approaches require ultra-dense sampling to ensure the rendering quality. Our DSLF works on sparse data and automatically filling in the missing data by leveraging different sampling patterns across the vertices and at the same time eliminates redundancies due to the network’s prediction capability. For real data\, we address the image registration problem as well as conduct texture-aware remeshing for aligning texture edges with vertices to avoid blurring. Next\, I present an end-to-end deep learning scheme to establish dense shape correspondences and subsequently compress 3d dynamic human bodies. Our approach uses sparse set of “panoramic” depth maps or PDMs\, each emulating an inward-viewing concentric mosaics (CM). We then develop a learning-based technique to learn pixel-wise feature descriptors on PDMs. The results are fed into an autoencoder-based network to achieve ultra-high compression ratio. \nBiography\nJingyi Yu is currently a Full Professor and Associate Dean of the School of Information Science and Technology at ShanghaiTech University. He is also affiliated with the Department of Computer and Information Sciences at University of Delaware. He received B.S. from Caltech in 2000 and Ph.D. from MIT in 2005. He has published over 120 papers at highly refereed conferences and journals\, and holds over 10 international patents on computational imaging. His research interests span a range of topics in computer vision and computer graphics\, especially on computational photography and non-conventional optics and camera designs. He is a recipient of the NSF CAREER Award and the AFOSR YIP Award\, and has served as an area chair of many international conferences including CVPR\, ICCV\, ECCV\, ICCP and NIPS. He is currently an Associate Editor of IEEE TPAMI\, IEEE TIP\, and Elsevier CVIU\, and will be program chair of ICPR 2020 and IEEE CVPR 2021. \n

SUMMARY:Error convolution structure in discrete Caputo derivatives and global consistency analysis
DESCRIPTION:Instructors/Speakers\nProf. Jiwei ZHANG\nSchool of Mathematics and Statistics\nWuhan University\nChina \nAbstract\nNonuniform time-stepping methods are promising for Caputo reaction sub-diffusion problems because they would be simple and effectiveness in resolving the initial singularity and other nonlinear behaviors occurred away from the initial time. Compared with traditional local methods for the first-order derivative\, the numerical analysis for nonlocal time-stepping schemes on non-uniform time meshes are challenging due to the convolution integral (nonlocal) form of fractional derivative. We develop a general framework for the stability and convergence analysis with three tools: a family of complementary discrete convolution kernels\, a discrete fractional Gronwall inequality (DFGI) and a global (convolutional) consistency analysis\, which is not limited to a specific time mesh by building a convolution structure of local truncation error. It seems that the present techniques are extendable to the variable-order\, distributed-order diffusion equations and other nonlocal-in-time diffusion problems. \nBiography\nProf Zhang is a Professor of School of Mathematics and Statistics\, Wuhan University. He got his PhD degree in Hong Kong Baptist University in 2009. His research area include fast algorithms for fractional PEDs and numerical methods for PDEs. \n

SUMMARY:Multi-View Fusion and Representation for Image Analysis
DESCRIPTION:Instructors/Speakers\nProf. Zhe XUE\nBeijing University of Posts and Telecommunications\nChina \nAbstract\nReal-world data can be described from multiple views. For instance\, an image can be described by color histogram\, SIFT\, HOG and other features. The content of a Web page can be described by texts\, images and videos. Describing an object from multiple perspectives constitutes multi-view data. Multi-view learning is to use the complementary nature of different views to improve the learning performance than using a single view. In this talk\, I will first briefly introduce some basic concepts and issues in multi-view learning. Then I will introduce some of our recent multi-view learning works for image analysis including multi-view dimensionality reduction\, multi-view clustering and incomplete multi-view classification. This report aims to help the audience understand the basic tasks and latest developments of multi-view learning. \nBiography\nDr. Zhe Xue received his Ph\,D. degree in Computer Science from school of computer and control engineering\, University of Chinese Academy of Sciences (UCAS) in 2017. After that\, he became an assistant professor at school of computer science\, Beijing University of Posts and Telecommunications. His research interest is generally in machine learning and data mining\, and particularly in multi-view learning and image analysis. Dr. Xue has published over 20 papers in international conferences and journals such as AAAI\, IJCAI\, IEEE TCSVT\, CVIU\, Information Sciences. He has undertook and participated in many projects\, including National Key R&D Program of China\, 973 Program\, National Natural Science Foundation of China and so on. He is the reviewer of ACM MM\, DASFAA\, IEEE TIFS\, Multimedia Tools and Applications and other international journals and conferences. He is also a member of the Intelligent Service Committee of the Chinese Association for Artificial Intelligence. \n

SUMMARY:Image Authentication and Tamper Localization
DESCRIPTION:Instructors/Speakers\nProf. Yulin WANG\nFull Professor of Wuhan University\nChina \nAbstract\nImage authentication can be used in many fields\, including e-government\, e-commerce\, national security\, news pictures\, court evidence\, medical image\, engineering design\, and so on. Since some content-preserving manipulations\, such as JPEG compression\, contrast enhancement\, and brightness adjustment\, are often acceptable—or even desired—in practical application\, an authentication method needs to be able to distinguish them from malicious tampering\, such as removal\, addition\, and modification of objects. Therefore\, the traditional hash-based authentication is not suitable for the application. As for the semi-fragile watermarking technique\, it meets the requirements of the above application at the expense of severely damaging image fidelity. In this talk\, we propose a hybrid authentication technique based on what we call fragile hash value. The technique can blindly detect and localize malicious tampering\, while maintaining reasonable tolerance to conventional content-preserving manipulations. The hash value is derived from the relative difference between each pair of the selected DCT coefficient in a central block and its counterpart which is estimated by the DC values of the center block and its adjacent blocks. In order to maintain the relative difference relationship when the image undergoes legitimate processing\, we make a pre-compensation for the coefficients. Finally\, we point out the direction using deep leaning technique for image authentication. \nBiography\nProf. Yulin Wang is a full professor and PhD supervisor in the School of Computer Science\, Wuhan University\, China. He got PhD degree in 2005 from University of London\, UK. Before that\, he had worked in National Institute of Research and Huawei@ for more than ten years.

SUMMARY:Exploring Deep Learning from Feedforward Neural Network Experiments
DESCRIPTION:Instructors/Speakers\nProf. Qin SHENG\nProfessor\nDepartment of Mathematics\nBaylor University\nUSA \nAbstract\nNeural network based deep learnings have been used for solving high dimensional (number of dimensions may reach more than several hundreds) partial differential equations. But what is a neural network and how to use it for approximating\, or predicting\, natural phenomena? In this exploration\, we tend to consider approximations of multivariate data through an explicit feedforward neural network (FNN) which is the basic type of neural network. The easy-to-follow formula provides a piecewise constant function for the data. Our FNN architecture has two hidden layers\, where the weights and thresholds are explicitly defined and no numerical optimization is required for training. The explicit algorithm does not rely on any tensor structure in multiple dimensions. Instead\, it automatically creates Voronoi tessellation of the domain based on the given data\, and generates a reliable piecewise constant approximation of the targeted function. These make the construction more practical for multiple applications. \nBiography\nProf. Sheng is a professor of Department of Mathematics\, Baylor University\, USA. He got his PhD degree from the University of Cambridge under the supervision of Professor Arieh Iserles in 1990. His research area include splitting and adaptive numerical methods for solving linear and nonlinear partial differential equations. \n

SUMMARY:Luminescent Materials
DESCRIPTION:Instructors/Speakers\nProf. Elena V. USHAKOVA\nAssociate Professor\nDepartment of Materials Science and Engineering\nCity University of Hong Kong \nAbstract\nNanostructured hybrid materials nowadays are prospective for utilizing them as an active media in novel photovoltaic and optoelectronic devices\, such as solar cells and light-emitting diodes. An implementing of lead sulfide quantum dots (PbS QDs) and lead-based perovskite films and nanocrystals (NCs) for future photonic devices with a focus on their optical properties will be discussed. \nWhile designing the nanostructured complex materials one of the main points that should be concerned is the interaction of the material compounds which can result\, for instance\, in the desired increase of the charge transfer efficiency or in the uncontrollable quenching of luminophore emission. The enhancement of the optical properties\, such as absorbance and emission of nanoparticles\, is achieved by the fabrication of hybrid material with plasmonic nanoparticles. In particular\, I will discuss strong enhancement of near‐infrared emission of PbS QDs induced by Cu2−xSe semiconductor plasmonic NCs both embedded into nanoporous silicate matrix which comes from resonant interaction of QD optical transition dipole with the near field of plasmons of semiconductor plasmonic NCs. Photocurrent and fill‐factor enhancements in meso‐superstructured perovskite solar cells with resonant silicon NPs resulted in increased light absorption will be also discussed. Another important issue in implementing of the nanostructured materials is the stability of their morphology and optical responses while operating at ambient conditions. Here\, the optical properties of highly luminescent colloidal perovskite NCs (CsPbX3\, where X=Cl/Br\, Br\, I) embedded in porous glass or opal matrices will be discussed. The use of a nanoporous glass or opal matrices allow obtaining the samples with blue\, green\, and red perovskite NCs and their mixtures possessing reproducible optical characteristics that are almost similar to that of colloidal solution.

SUMMARY:Electron-Lattice Interactions in Lead and Lead-Free Perovskite Single Crystals
DESCRIPTION:Instructors/Speakers\nProf. Bo WU\nProfessor\nSouth China Academy of Advanced Optoelectronics\nSouth China Normal University in Guangzhou\nChina \nAbstract\nRecently\, perovskite materials have gained widespread attentions due to their high potential in optoelectronic applications from solar cells\, light-emitting diodes\, lasers to photodetectors. For example\, the certificated power conversion efficiencies of perovskite solar cells have exceeded 25%\, on par with that of silicon. The external quantum efficiencies of perovskite green and red light emitting diodes have reached 20%\, a value approaching the best performed OLEDs. Despite the rapid progresses in improving the efficiencies\, there remain a lot of questions to be answered about the physical mechanisms lying behind the great successes. In this talk\, I will focus on the interactions between the electrons and the perovskite lattice\, which are complicated by the soft lead-halide bonds\, the hybrid nature of the lattice comprising of both organic and inorganic parts. The talk will be divided into two parts: (1) the thermal-driven dynamical Rashba splitting in lead perovskite single crystals and (2) the strong electron-phonon interactions in bismuth perovskite single crystals. In the first part\, through temperature-dependent photoluminescence\, Raman spectroscopy and molecular dynamical simulations\, we revealed that thermal driven lattice anharmonic polar motions result in dynamical Rashba splitting in lead halide perovskite single crystals\, which may lead to indirect tail states and prolong the carrier lifetimes. In the second part\, through photoluminescence and transient reflection techniques\, we show that a bismuth perovskite single crystal has a carrier mobility of only 0.05 cm2s-1V-1 and relative bright indirect emission\, which imply strong carrier localization effect by the electron-phonon coupling in the system. These findings provide significant insights on the underlying physical mechanisms of perovskites\, which may pave the way to further development of perovskite optoelectronic materials and their commercialization. \nBiography\nProfessor Wu Bo obtained his bachelor degree in Beijing Normal University in 2009 and Ph.D. degree in Nanyang Technological University in 2014. Now he is a professor in the South China Academy of Advanced Optoelectronics\, South China Normal University. His research interest is using spectroscopies and ultrafast spectroscopies to uncover the physical mechanisms of optoelectronic materials and devices\, e.g.\, perovskite solar cells and light emitting diodes\, organic solar cells\, etc. Till now\, he has published more than 40 papers in high-impact journals such as Nature Communications\, Advanced Materials\, Advanced Functional Materials\, ACS Nano etc. He has also published a book on plasmonic organic solar cells and a book chapter on perovskite single crystals in Springer and Wiley\, respectively. \n

SUMMARY:Web Identity Security (WIS) in Big Data Er
DESCRIPTION:Instructors/Speakers\nDr. Wenyin LIU\nWIS Lab\nGuangdong University of Technology \nAbstract\nA web identity is an identifier that uniquely identifies and represents an entity in the Cyberspace. Web identity security focuses on accurate identity verification and prevention of identity impersonation\, fraud\, leakage\, theft\, etc. Nowadays\, the increasing scale of the Web gives rise to the problems of “Password Fatigue”\, “Phishing Attacks” and “Brute Force Password Attacks”\, and brings great challenges to the currently dominant password-based web identity authentication scheme. \nIn this talk\, we will first present the threats and challenges to Web identity security and then introduce our solutions and suggestions. In particular\, we propose a new web identity authentication mechanism by introducing a module named “Trusted User Agent” in the authentication process\, which is compatible with the current password-based mechanism. Specifically\, the user account information is automatically generated by\, stored in the trusted user agent\, and directly sent to the corresponding server\, which authorizes the corresponding session on the specific terminal after successful authentication. This forms a secure closed authentication loop\, in which credentials will never be sent to\, and stolen by phishers at the browser. The proposed mechanism helps users automatically register new accounts with unlinkable identities and strong passwords\, thus free from password cracking. We develop a system based on this mechanism and implement automatic change of passwords as well. Analyses and user studies have been conducted to show its security\, usability\, and deployability\, being superior to the current password-based mechanism. \nA phishing detection mechanism based on parasitic community will then be presented\, which not only reaches an accuracy of 99.2%\, but is the only system in the world capable of discovering phishing targets. A deep learning based solution will also be presented\, which can detect a phishing URL with a very fast speed (20ms) and a very high precision (TPR=98.45% while FPR=0.01%). \nBiography\nDr. Liu Wenyin is currently a Professor in School of Computer Science and Technology\, Guangdong University of Technology. He was Deputy Director of Multimedia software Engineering Research Centre at the City University of Hong Kong from 2013 to 2016\, an assistant professor in the Department of Computer Science at the City University of Hong Kong from 2002 to 2012\, and a full time researcher at Microsoft Research China/Asia from 1999 to 2001. His current research interests include blockchain\, anti-phishing\, Web identity authentication and management. He has BEng and MEng degrees in computer science from Tsinghua University\, Beijing and a doctoral degree from the Technion\, Israel Institute of Technology\, Haifa. In 2003\, he was awarded the IAPR/ICDAR Outstanding Young Researcher Award. In 2010\, he was elected to IAPR Fellow for his contributions to graphics recognition and anti-phishing. He had been TC10 chair of IAPR for two terms 2006-2010. He had been on the IAPR Fellow Committee for three terms 2010-2016.

SUMMARY:The Technology and Application of Speech Translation
DESCRIPTION:Instructors/Speakers\nDr. Boxing CHEN\nMachine Intelligence Lab\nDAMO Academy of Alibaba Group \nAbstract\nWith the significant performance improvement of automatic speech recognition and machine translation\, speech translation comes to the real life from the science fiction. There are two paradigms for speech translation: cascaded and end2end speech translation systems. Due to the size of the available training data\, cascaded speech translation system still over-performs the end2end speech translation system. However\, cascaded speech translation system also suffers the error propagation problem. ASR errors\, punctuation restoration\, language informality\, and disfluency etc. are the main challenges for speech translation. We invest effort in all components of the cascaded speech translation system. We achieve improvement for each component in the pipeline\, therefor result better overall speech translation performance. We show some scenarios at Alibaba\, which we apply speech translation for technical lecture\, communications between buyer and seller\, oversea traveling\, etc. \nBiography\nBoxing Chen is a Senior Algorithm Expert at Machine Intelligence Lab\, DAMO Academy of Alibaba Group. He works on natural language processing\, mainly focus on machine translation. Prior to Alibaba\, he was a Research Officer at the National Research Council Canada (NRC)\, Senior Research Fellow at the Institute for Infocomm Research in Singapore\, a Postdoc at FBK-IRST in Italy and a Postdoc at the University of Grenoble in France. He received his PhD degree from Chinese Academy of Science and Bachelor degree from Peking University in China. He has co-authored more than 50 papers in the NLP conferences and journals. He has received the “The best paper award” from MT Summit 2013\, and “The best paper award nomination” from ACL 2013. His teams ranked the first place in WMT 2018 for five translation tasks and six quality estimation sub-tasks; the first place in WMT 2017 Russian-to-English translation\, the first place in the NIST 2012 OpenMT Chinese-to-English translation\, the first place in the IWSLT 2007 Chinese-to-English translation and IWSLT 2005 Chinese-to-English and Japanese-to-English translation\, etc. \n
