Title: DATA FOR THE PEOPLE – Wie wir die Macht über unsere Daten zurückgewinnen!
Speaker: Dr. Andreas Weigend, ehemaliger Chefwissenschaftler von Amazon, hat in seinem Buch „Data for the People“ beschrieben, wie Daten die Qualität und den Zuschnitt individueller Dienstleistungen verbessern. Gleichzeitig wendet er sich gegen staatliche Kontrollen, wie sie jetzt die kommunistische Partei der Volksrepublik China durchsetzt. Weigend lebt und lehrt unter anderem in Shanghai und San Franciso. Er weiß, dass wir den Datengeist nicht mehr in die Flasche zurück bekommen werden. Aber können wir die Macht über unsere Daten zurückerobern, können wir Datenkontrolle erlangen und bewahren? Wie verträgt sich die individuelle Freiheit, keine Datenquelle zu sein, mit den ökonomischen und gesellschaftspolitischen Vorteilen, die die Verarbeitung von Big Data bringt? Muss es nicht auch in einer transparenten Wissengesellschaft ein Grundrecht auf private Abschottung geben?

Title: AI-Kindergarten: What to do when the training data become too big?
Speaker: Danko Nikolic is a brain and mind scientist, as well as an AI practitioner and visionary. His work as a senior data scientist at Teradata focuses on helping customers with AI and data science problems. In his free time, he continues working on closing the mind-body explanatory gap, and using that knowledge to improve machine learning and artificial intelligence.
Abstract: To create human level AI, huge amounts of training data would be needed in case one is using the AI technology of today. This is not necessarily going to be possible. Rather, novel technological approaches will be needed to i) organise AI technology and ii) provide training sets for that AI. I will describe a way to ‘compress’ data into a form of intelligent knowledge, which can then be used to train other intelligent systems. A metaphor for that training approach is a kindergarten. Here, the adult educator has knowledge on the world in which the kids need to live. The educator knowledge is stored in a condensed form–from huge amounts of data to a limited number of rules. This knowledge is then transferred to kids by the means of interacting with them. Similarly, the only way to achieve high levels of intelligence in machines is through offering such condensed knowledge rather than providing ‘raw’ training datasets, as is the case today.

Title: Towards Interactive Data Exploration
Speaker: Carsten Binnig is a Full Professor in the Computer Science department at at TU Darmstadt and an Adjunct Associate Professor in the Computer Science department at Brown University. Carsten received his PhD at the University of Heidelberg in 2008. Afterwards, he spent time as a postdoctoral researcher in the Systems Group at ETH Zurich and at SAP working on in-memory databases. Currently, his research focus is on the design of data management systems for modern hardware as well as modern workloads such as interactive data exploration and machine learning. He has recently been awarded a Google Faculty Award and a VLDB Best Demo Award for his research.
Abstract: Technology has been the key enabler of the current Big Data movement. Without open-source tools like R and Hadoop, as well as the advent of cheap, abundant computing and storage in the cloud, the ongoing trend toward datafication of almost every research field and industry could never have occurred. However, the current Big Data tool set is ill-suited for interactive data exploration making the knowledge discovery process a major bottleneck in our data-driven society. In this talk, we will first give an overview of challenges for interactive data exploration on large data sets and then present current research results that revisit the design of existing data management systems, from the query interface to the storage and the underlying hardware, to enable interactive data exploration.
Time and Location: Wednesday, March 7th, 11:00 am, Big Data Lab Frankfurt at the Chair for Databases and Information Systems (DBIS), Goethe-University Frankfurt.

Title: Full conditional probabilities lead to indeterminacy in probability values
Speaker: Prof. Dr. Gregory Wheeler, Professor of Philosophy and Computer Science, Head of Philosophy and Law Department, Frankfurt School of Finance & Management
Abstract: The purpose of this talk is to show that if one adopts conditional probabilities as the primitive concept of probability, then one must accept that at least some probability values may be indeterminate, and that some probability questions may fail to have numerically precise answers. (Joint with Fabio Cozman.)

Title: Deep Learning (m)eats Databases
Speaker: Jens Dittrich (Saarland University) is a Full Professor of Computer Science in the area of Databases, Data Management, and Big Data at Saarland University, Germany. Previous affiliations include U Marburg, SAP AG, and ETH Zurich. He received an Outrageous Ideas and Vision Paper Award at CIDR 2011, a BMBF VIP Grant in 2011, a best paper award at VLDB 2014 (the second ever given to an E&A paper), two CS teaching awards in 2011 and 2013, as well as several presentation awards including a qualification for the interdisciplinary German science slam finals in 2012 and three presentation awards at CIDR (2011, 2013, and 2015). He has been a PC member and area chair/group leader of prestigious international database conferences and journals such as PVLDB/VLDB, SIGMOD, ICDE, and VLDB Journal. At Saarland University he co-organizes the Data Science Summer School (http://datasciencemaster.de).
Since 2013 he has been teaching some of his classes on data management as flipped classrooms. See http://datenbankenlernen.de or http://youtube.com/jensdit for a list of freely available videos on database technology in German (introduction to databases) and English (database architectures and implementation techniques). He is also author of a “flipped textbook” on databases. Since 2016 he has been working on a start-up at the intersection of deep learning and databases (http://daimond.ai).
His research focuses on fast access to big data including in particular: data analytics on large datasets, main-memory databases, database indexing, reproducability, and deep learning.
Abstract: Imagine a machine that is able to compose music and write poems; paint realistic artificial images and dream up video from textual descriptions; paint pictures or entire videos in the style of any artist; translate in-between any pair of natural languages. A machine that can recognize any content in images and videos; diagnose diseases, imitate spoken language — in any voice. A machine that wins games thought to be exclusive to human intelligence. All of that with superhuman performance of course.
Sounds like science fiction? Well, then welcome to the year 2017!
Currently we are witnessing the biggest revolution in computer science since the invention of the Internet. Deep Learning is shaking the world of computer science and overrunning entire (sub-)disciplines.
In this talk I will briefly sketch some of the recent advances in deep learning and what they have to do with databases. Where are synergies? Where should we be looking at? This talk will have a particular focus on recent technical developments in the intersection of databases and/or deep learning in Europe.

Title: Introducing the DFG project „Corpus Nummorum Thracorum Klassifizierung der Münztypen und semantische Vernetzung über Nomisma.org“
Speaker: Dr. Karsten Tolle, Director, Frankfurt Big Data Lab.
Abstract: The talk will introduce the project, the current situation of the existing data, and our current first ideas on how to reach a typology definition within the project.
The portal Corpus Nummorum Thracorum (CNT) is a virtual tool for the collection and categorisation of coins from the ancient land of Thrace (set up in a previous DFG-project).
The project will make use of the potential offered by this existing information infrastructure by utilising the data recorded in CNT, together with other sources that likewise follow the approach of Linked Open Data, to present a typology of the coins of ancient Thrace.
The types recorded as norm data in the form of URIs on Nomisma.org will be able to be used as references and research resources by numerous other projects in the Semantic Web.
In this project we plan to set up an analysis database to be fed with CNT-data and additional sources, and run experiments to cluster or classify coin data, based on different methodologies/features.
The project will last 36 months and it is in cooperation with Berlin-Brandenburgische Akademie der Wissenschaften (Prof. Dr. Dr. hc. mult. Martin Grötschel), and Münzkabinett – Staatliche Museen zu Berlin ( Prof. Dr. Bernhard Weisser).
Time and Location: Wednesday, May 17, 2017, 2:30 pm, Big Data Lab Frankfurt at the Chair for Databases and Information Systems (DBIS), Goethe-University Frankfurt.

Title: 5000 Years: Tax, Technology & Analytics
Speaker: Dr. Dirk Tassilo Hettich, Senior Consultant Tax Technology & Analytics
Bio: After having researched brain-computer interfacing for communication and control for almost 10 years, Dirk decided it is time to see how big data and advanced analytics do apply in an economic context and joined the Tax Techology & Analytics team at EY Stuttgart led by Florian Buschbacher in March of 2016. Since then he has applied his software development, machine learning, and visualization expertise in multiple client projects and is still amazed by all the real-world potential of artificial intelligence.
Abstract: New tools for new requirements in tax – from paper, calculators, and spreadsheets towards real-time tax including advanced analytics and machine learning. Digital transformation is happening in all aspects of a company and taxation intersects with almost all such aspects. The Tax Technology & Analytics team resolves complexity by applying state-of-the-art software development, database, and analytics technologies on a daily basis. This talk aims at giving insights to where big data and advanced analytics do apply in the supposedly dusty topic of taxation including working examples.

Title: MariaDB, MySQL and Four Decades of RDBMS Theory and Practice
Speaker: Kaj Arnö, Chief Evangelist at MariaDB Corporation
Bio: Software industry generalist, having serving as VP Professional Services, VP Engineering, CIO and VP Community Relations of MySQL AB prior to the acquisition by Sun. At Sun, served as MySQL Ambassador to Sun and Sun VP of Database Community. Board member of Carus Ltd Ab (Åland) and Footbalance Systems Oy (Helsinki, Finland). Past founder, CEO and 14 year main entrepreneur of Polycon Ab (Finland). Founder of what is now MariaDB Corporation Ab in 2010. Founded Green Elk (Outdoors Community) 2014. Now serving as Chief Evangelist of MariaDB Corporation.
Abstract: Plus ça change, plus c’est la même chose: Using databases require developers to be able to combine theory and practice in a way that has changed its form surprisingly little since the 1980s. Underlying themes have remained and seem cyclic. Central control moves to decentralised and back to central; memory constraint get relieved, only to again take effect in microservices. Complex pre-relational structures get a revival in in NoSQL, only to go back to relational again. Kaj Arnö takes an architectural look at RDBMSes spanning the times he’s been exposed to databases, since early 1980s.

Title: Big Data and The Great A.I. Awakening.
Speaker: Prof. Roberto V. Zicari, Frankfurt Big Data Lab, (Johann Wolfgang Goethe-Universität Frankfurt am Main)
Companies with big data pools can have great economic power. Today, that shortlist includes Google, Microsoft, Facebook, Amazon, Apple and Baidu.
I think we’re just beginning to understand the implications of data as an economic asset.
Steve Lohr (a journalists from The New York Times) had a recent conversation with Andrew Ng, a Stanford professor who worked at Google X, co-founder of Coursera and now chief scientist at Baidu. He asked him why Baidu, and he replied there were only a few places to go to be a leader in A.I. Superior software algorithms, he explained, may give you an advantage for months, but probably no more. Instead, Ng said, you look for companies with two things — lots of capital and lots of data. “No one can replicate your data,” he said. “It’s the defensible barrier, not algorithms.”
I asked myself the following question: Technology is moving beyond increasing the odds of making a sale, to being used in higher-stakes decisions like medical diagnosis, loan approvals, hiring and crime prevention. What are the societal implications of this?
steve Lohr argues that the new decisions that data science and AI tools are increasingly being used to make — or assist in making — are fundamentally different than marketing and advertising. In marketing and advertising, a decision that is better on average is plenty good enough. You’ve increased sales and made more money.
But the other decisions are practically and ethically very different. These are crucial decisions about individual people’s lives. For these kinds of decisions, issues of accuracy, fairness and discrimination come into play.
What we probably need is some sort of auditing tool; the technology has to be able to explain itself, to explain how a data-driven algorithm came to the decision or recommendation that it did. And it would important that a “human remains in the loop” for most of these kinds of decisions for the foreseeable future.
