Albert Bifet — ACM Distinguished Speaker

Title: IoT Massive Online Analytics

Abstract: Big Data and the Internet of Things (IoT) have the potential to fundamentally shift the way we interact with our surroundings. The challenge of deriving insights from the Internet of Things (IoT) has been recognized as one of the most exciting and key opportunities for both academia and industry. Advanced analysis of big data streams from sensors and devices is bound to become a key area of data mining research as the number of applications requiring such processing increases. Dealing with the evolution over time of such data streams, i.e., with concepts that drift or change completely, is one of the core issues in stream mining. In this talk, I will present an overview of data stream mining, and I will introduce some popular open source tools for data stream mining.

Title: Mosaics in Big Data: Stratosphere, Flink and beyond

Abstract: The global database research community has greatly impacted the functionality and performance of data storage and processing systems along the dimensions that define “big data”, i.e., volume, velocity, variety, and veracity. Locally, over the past five years, we have also been working on varying fronts. Among our contributions are: (1) establishing a vision for a database-inspired big data analytics system, which unifies the best of database and distributed systems technologies, and augments it with concepts drawn from compilers (e.g., iterations) and data stream processing, as well as (2) forming a community of researchers and institutions to create the Stratosphere platform to realize our vision. One major result from these activities was Apache Flink, an open-source big data analytics platform and its thriving global community of developers and production users. Although much progress has been made, when looking at the overall big data stack, a major challenge for database research community still remains. That is, how to maintain the ease-of-use despite the increasing heterogeneity and complexity of data analytics, involving specialized engines for various aspects of an end-to-end data analytics pipeline, including, among others, graph-based, linear algebra-based, and relational-based algorithms, and the underlying, increasingly heterogeneous hardware and computing infrastructure. At TU Berlin, DFKI, and the Berlin Big Data Center (BBDC), we aim to advance research in this field via the Mosaics project. Our goal is to remedy some of the heterogeneity challenges that hamper developer productivity and limit the use of data science technologies to just the privileged few, who are coveted experts.

Picture of Volker Markl Biography: Volker Markl is a Full Professor and Chair of the Database Systems and Information Management (DIMA) Group at the Technische Universität (TU) Berlin, Director of the Intelligent Analytics for Massive Data Research Group at the German Research Center for Artificial Intelligence (DFKI), and Director of the Berlin Big Data Center (BBDC). He has published numerous research papers on indexing, query optimization, lightweight information integration, and scalable data processing. He holds 19 patents, has transferred technology into several commercial products, and advises several companies and startups. He has been Speaker and Principal Investigator of the DFG funded Stratosphere research project that resulted in the Apache Flink Big Data Analytics System. Currently, he serves as the Secretary of the VLDB Endowment and was elected as one of Germany's leading Digital Minds (Digitale Köpfe) by the German Informatics (GI) Society. Most recently, Volker and his team earned an ACM SIGMOD Research Highlight Award 2016 for their work on “Implicit Parallelism Through Deep Language Embedding.”

Title: New Challenges and Opportunities in Stream Processing: Transactions, Predictive Analytics, and Beyond

Abstract: Stream processing has been an area of ongoing research since the early 2000s. Fueled by industry’s growing interest in dealing with high-velocity big data in near real-time settings, there has been a resurgence of recent activity in both research and engineering of large-scale stream processing systems. In this talk, we will examine the state of the art, focusing in particular on key trends of the past five years with an outlook towards the next five years. I will also give examples from our own work, including stream processing in transactional settings as well as predictive time series analytics for the Internet of Things. Transactional stream processing broadly refers to processing streaming data with correctness guarantees. These guarantees include not only properties that are intrinsic to stream processing (e.g., order, exactly-once semantics), but also ACID properties of traditional OLTP-oriented databases, which arise in streaming applications with shared mutable state. In our recent work, we have designed and built the S-Store System, a scalable main-memory system that supports hybrid OLTP+streaming workloads with strict correctness needs. A use case that best exemplifies the strengths of S-Store is real-time data ingestion. Thus, I will also discuss the requirements of modern data ingestion and how to meet them using S-Store, especially within the context of our BigDAWG Polystore System. The Internet of Things (IoT) envisions a world made up of huge numbers of sensors and computing devices that interact in intelligent ways (e.g., self-driving cars, industrial automation, mobile phone tracking). The sensors produce massive amounts of data and the computing devices must figure out how to use it. The preponderance of this data is time series. Anomaly detection, i.e., the process of finding patterns that do not conform to expected behavior, over time series is an important capability in IoT with multiple potential applications. Through anomaly detection, we can identify unusual environmental situations that need human attention, distinguish outliers in sensor data cleaning, or pre-filter uninteresting portions of data to preserve computing resources, to name a few. In our new Greenhouse Project, we have been exploring “zero-positive” 1 machine learning (ML) techniques for efficient and accurate prediction of anomalous patterns over high volumes of time series data. This also includes the design of a new accuracy model for evaluating range-based anomaly detection algorithms more effectively. I will share some of our early results from this project, and then conclude the talk with a discussion of future research directions.

Title: WEKA: Teaching an old bird new tricks

Abstract: This invited talk will provide an overview of the WEKA project, a software development effort at Waikato university that has spanned more than 15 years. The project has produced an open-source software workbench for machine learning and data mining that is written in Java and incorporates several graphical user interfaces, a command-line interface, and an API. The talk will focus on some of the more recent additions to the software that have enabled integration of other tools from the software ecosystem for data science: R, Python, and DeepLearning4j, a deep learning library written in Java.
