Title: Demystifying Blockchains: Decentralized and Fault- tolerant Storage for the Future of Big Data?
Abstract: Bitcoin is a successful and interesting example of a global scale peer-to-peer cryptocurrency that integrates many techniques and protocols from cryptography, distributed systems, and databases. The main underlying data structure is blockchain, a scalable fully replicated structure that is shared among all participants and guarantees a consistent view of all user transactions by all participants in the cryptocurrency system. The novel aspect of Blockchain is that historical data about currency transactions is maintained in the absence of any central authority. This property of Blockchain has given rise to the possibility that the future applications will transition from centralized databases to a fully decentralized storage based on blockchains. In this talk, we start by developing an understanding of the basic protocols used in blockchain, and elaborate on its main advantages and limitations. To overcome these limitations, we provide the necessary distributed systems background in managing large scale fully replicated ledgers, using Byzantine Agreement protocols to solve the consensus problem. Finally, we expound on some of the most recent efforts to design scalable and efficient blockchains.

Title: Fault Tolerant Data Stream Processing in Cooperation with OLTP Engine

Abstract: In recent years, with the increase of big data and the spread of IoT technology and the continual evolution of hardware technology, the demand for data stream processing is further increased. Meanwhile, in the field of database systems, a new demand for HTAP (hybrid transactional and analytical processing) that integrates the functions of on-line transaction processing (OLTP) and on-line analytical processing (OLAP) is emerging. Based on this background, our group started a new project to develop data stream processing technologies in the HTAP environment in cooperation with other research groups in Japan. Our main focus is to develop new data stream processing methodologies such as fault tolerance in cooperation with the OLAP engine. In this paper, we describe the background, the objectives and the issues of the research.

Title: Blockchain-powered Big Data Analytics Platform

Abstract: As crypto-currencies and other business blockchain applications are becoming mainstream, the amount of transactional data as well as business contracts and documents captured within various ledgers are getting bigger and bigger. Further, blockchains provide enterprises and consumers with greater confidence in the integrity of the data that have been captured. This gives rise to the new level of analytics that marries the advantages of both blockchain and big data technologies to provide trusted analysis on validated and quality big data. Particularly, blockchain-based big data is a perfect source for subsequent analytics because the big data maintained on the blockchain is both secure (i.e., tamper-proof and cannot be forged) and valuable (i.e., validated and abundant). In addition, data integration and advanced analysis across on-chain and off-chain data present enterprises with even more complete business insights. In this paper, we first discuss a blockchain-based business application for micro-insurance and AI marketplaces, which render blockchain-generated big data scenarios. Then, we describe the design of a blockchain-powered big data analytics platform as well as our initial steps being taken along the development of this platform.

Title: Analysis of Narcolepsy Based on Single-Channel EEG Signals
Abstract: A normal person spends about a third of his life in sleep. Healthy sleep is vital to people's normal lives. Sleep analysis can be used to diagnose certain physiological and neurological diseases such as apnea, insomnia and narcolepsy. This paper will introduce the sleep stage and the corresponding electroencephalogram (EEG) characteristics at each stage. We used the deep convolutional neural network (CNN) to classify original EEG data with narcolepsy. We use perturbations based on frequency to generate adversarial examples to analyze the characteristics of narcolepsy in different sleep stages. We find that perturbations at specific frequencies affect the classification results of deep learning.

Title: Design of the Cogno Web Observatory for Characterizing Online Social Cognition
Abstract: It is important to occasionally remember that the World Wide Web (WWW) is the largest information network the world has ever seen. Just about every sphere of human activity has been altered in some way, due to the web. Our understanding of the web has been evolving over the past few decades ever since it was born. In its early days, the web was seen just as an unstructured hypertext document collection. However, over time, we have come to model the web as a global, participatory, socio-cognitive "space". One of the consequences of modeling the web as a space rather than as a tool, is the emergence of the concept of Web observatories. These are application programs that are meant to observe and curate data about online phenomena. In this talk, we present the underlying model behind our Web observatory called Cogno, that is meant to observe online social cognition. Social cognition refers to the way social discourses lead to the formation of collective worldviews. Social media is modeled as a "marketplace of opinions" where different opinions come together to form "narratives" that not only drive the discourse, but may also bring some form of returns to the opinion holders. The problem of characterizing social cognition is defined as breaking down a social discourse into its constituent narratives, and for each narrative, its key opinions, and the key people driving the narrative.

Title:  Polystore Data Management Systems for Managing Scientific Data-sets in Big Data Archives
Abstract:  Large scale scientific data sets are often analyzed for the purpose of supporting workflow and querying. User need to query over different data sources. These systems manage intermediate results. Most prototypes are complex and have an ad hoc design. These require extensive modifications in case of growth of data and change of scale, in terms of data or number of users. New data sources may arise to further complicate the ad hoc design. The polystore data management approach provides 'data independence' for changes in data profile, including addition of cloud data resources. The users are often provided a quasi- relational query language. In many cases, the polystore systems support distinct tasks that are user defined workflow activity, in addition to providing a common view of data resources.
Biography:  Dr. Subhash Bhalla teaches at University of Aizu since 1993. His area of study is Distributed Information Systems. He completed studies up to PhD from IIT Delhi. He started teaching at School of Computer and Systems Sciences at JNU in 1986. After that, he briefly worked at Sloan School of Management at MIT during 1987-88.

Title: Humble Data Management to Big Data Analytics/Science: A Retrospective Stroll
Abstract: We are on the cusp of analyzing a variety of data being collected in every walk of life in diverse ways and holistically as well as developing a science (Big Data Science) to benefit humanity at large in the best possible way. This warrants developing and/or using new approaches -- technological, scientific, and systems -- in addition to building upon and integrating with the ones that have been developed so far. With this ambitious goal, there is also the risk of these advancements being misused or abused as we have seen so many times with respect to new technologies. In this presentation, we take the audience on a retrospective stroll on the approaches that have come about for managing and analyzing data over the last 40+ years. Since the advent of Database Management Systems (or DBMSs) and especially the Relational DBMSs (or RDBMSs), data management and analysis have seen several significant strides. Today, data has become an important tool (or even a weapon) in society and its role and importance is unprecedented. The goal of this paper is to provide the audience an understanding of data management and analysis approaches with respect to where we have come from, motivations for developing them, and what this journey has been about in a short span of 40+ years. We sincerely hope this presentation provides a historical as well as a pedagogical perspective for those who are new to the field and provides a useful perspective that they can relate to and appreciate for those who have been working and contributing to the field.

Title: Fusion of Game Theory and Big Data for AI Applications
Abstract: With the increasing reach of the Internet, more and more people and their devices are coming online which has resulted in the fact that, a significant amount of our time and a significant number of tasks are getting performed online. As the world moves faster towards more automation and as concepts such as IoT catch up, a lot more (data generation) devices are getting added online without needing the involvement of human agents. The result of all this is that there will be lots (and lots) of information generated in a variety of contexts, in a variety of formats at a variety of rates. Big data analytics therefore becomes (and is already) a vital topic to gain insights or understand the trends encoded in the large datasets. For example, the worldwide Big Data market revenues for software and services are projected to increase from $42$ $Billion$ USD in 2018 to $103$ $Billion$ in 2027. However, in the real-world it may not be enough to just perform analysis, but many times there may be a need to operationalize the insights to obtain strategic advantages. Game theory being a mathematical tool to analyze strategic interactions between rational decision-makers, in this paper, we study the usage of Game Theory to obtain strategic advantages in different settings involving usage of large amounts of data. The goal is to provide an overview of the use of game theory in different applications that rely extensively on big data. In particular, we present case studies of four different Artificial Intelligence (AI) applications namely Information Markets, Security systems, Trading agents and Internet Advertising and present details for how game theory helps to tackle them. Each of these applications has been studied in detail in the game theory literature, and different algorithms and techniques have been developed to address the different challenges posed by them.
