Gunter Saake, Jacob KrügerDatabase Operation Tuning
(David Broneske)
A current trend in database systems is to tune algorithms at a very fine granularity.
Current code optimizations are controversially discussed, but a clear applicability of
them is missing. Consequently, discuss the applicability of a subset of available
code optimizations on selected database algorithms.

Evolution of column-oriented RDBMS operations
(Bala Gurumurthy)
Current trend in RDBMS is moving towards close-to-metal re-implementation of
typical DBMS operations for underlying hardware. With the availability of newer
features (like multi-core, SIMD) as well as device architectures (GPU, FPGAs) in the
hardware landscape researches are done in tuning the operations to adapt to the
hardware. In this work, we would survey the evolution of DBMS operations with
reference points for the newer hardware availabilities. The work, in the end,
provides a view on the hardware landscape with changes being applied to the
DBMS operations and also the areas of dense and sparse researches.

As an alternative, hot input data buffers are proposed to be stored in a GPU for further processing without transfer overhead. In this work, we will look into the issue of caching in GPU and list the possible alternatives for caching in a GPU. Since column cannot be directly stored within a GPU, we look for alternative representation of data that is still sufficient for performing database operations over them (like bitmap, position list etc.) Overall, the work presents the state of the art techniques in intermediate representation for storing column in a GPU as well as the buffer management techniques used for caching in GPU. • Waste Not..

Paving the way from game theory to cooperative DB components (Gabriel Campero Durand) Research in economy and game theory is ripe with models that seek to understand how agents compete for resources and how, through market design, they can be encouraged to collaborate, converging to optimal allocations for the group. In data management research there have been some attempts to adopt these models, for example in creating marketplaces for data fragmentation in the Mariposa Stream Processing System. However, this is not widely adopted. With the development of agent-based machine learning solutions for data management, it is possible that these techniques will gain relevance. In this topic we aim to start with a quick review on economic and game theory concepts, followed by a careful collection and discussion of related work. We conclude by proposing, based on discussions, potential applications in storage engine management, query processing and cloud computing. • Pastine, Ivan and Pastine Tuvana.

Multi-agent deep reinforcement learning and databases (Gabriel Campero Durand) The success of single agent deep reinforcement learning naturally creates interest in evolving to multiagent solutions, like DeepMind's AlphaStar. These are specially interesting since they address realistic use cases, where agents are not in entire control of a system. In this conference topic we will categorize the state of the art in the field, highlighting challenges and potentials in some approaches. In addition, we take a deep dive into one mature approach. We conclude by considering the feasibility of applying such approach to a database task. • Database Query Optimization with Deep Reinforcement Learning: https://www.youtube.com/watch?v=Rw3ewEXOKC8 • Hernandez-Leal, Pablo, Bilal Kartal, and Matthew E.

Learning from demonstrations with deep reinforcement learning (Gabriel Campero Durand) Though reinforcement learning is a useful online method, it is often infeasible to train agents by interacting with a real-world system. Moreover, simulated environments are costly to produce. Thus, training agents in an offline manner, by using traces from an expert interacting with the system, is particularly compelling for practitioners. In this student conference topic we study in detail such approach. We consider how it has been used (or proposed to be used) in recent data management cases, and we list existing frameworks for off-the-shelf learning from demonstrations. • Hester, Todd, Matej Vecerik, Olivier Pietquin, Marc Lanctot, Tom Schaul, Bilal Piot, Dan Horgan et al.

Machine learning on networks and Graph-based recommenders (Gabriel Campero Durand) Graph databases are a special kind of general data management system optimized for network- oriented analytical queries and storage. They are mainly developed to support a specific representation of a graph, namely property graphs. However, recent trends require further features from these databases, either to support novel data representations (embeddings) or highly efficient feature engineering processes. In this seminar topic we aim to study some of these trends, by considering one of two applications: machine learning on networks, or graph-based recommenders. For the chosen domain we describe carefully the domain, we take a detailed look at a given example study, and we outline the implications for system development. • Cao, Yixin, Xiang Wang, Xiangnan He, and Tat-Seng Chua.

Interests in Systematic Software Reuse
(Jacob Krüger)
Systematic software reuse in terms of software product lines is often only
introduced after a larger set of different variants has evolved. For varying reasons,
including cost reduction, faster development, or improved management, these
variants are merged and integrated into a platform (reverse engineering). While
there are several case studies that report on the migration processes and
experiences, we still need a detailed analysis of the actual industrial motivations
that lead to the adoption of product lines. To this end, we aim to analyze various
topics on the adoption of software product lines at different venues and in
different years. Topics may include the motivation and costs for extracting features,
the evolution of software, or synchronizing independent variants at SPLC, ICSE, or
VaMoS.
• A defined selection of topics, venues, and years can be defined to scope the extent of the analysis

Conference on Systems and Software Product Line. 14-24. ACM.Automated Test Refactoring
(Jacob Krüger)
Software is regularly updated or refactored, for example, to remove errors,
introduce new features, or migrate towards a new technology. However, any
change in the productive software also means that corresponding test cases
may break or are not sufficient anymore. The purpose of this survey is to
identify and summarize existing techniques on automated test case
refactoring, meaning techniques that track code changes and support
developers in maintaining the test cases for these artifacts.

Programming Perspectives. Chapter Refactoring Test CodeHow do We Forget?
(Jacob Krüger)
Understanding a program is an essential activity in software engineering and the
research area of program comprehension is extensively investigated. However,
most studies are concerned with recovering understanding of a program and how
to improve code design for this purpose. Such processes resemble learning of
artifacts. In contrast, the process of forgetting in software engineering is rarely
investigated. With this project, we aim to provide an overview on existing studies
that are concerned with forgetting in software engineering and what factors affect
developers' memory.

(Roman Zoun)
Mass spectrometers are devices to digitize real world samples with growing success on the
market. The technology sequences proteins to identify protein biomarkers of biological
environments, such as oceans, humans, or microbial communities which are used in the
research fields proteomics, metaproteomics and metabolomics. These biomarkers are
similar to a fingerprint and can be used to identify the sample data. Due to the fast quality
upgrades of the mass spectrometer, they produce ever-increasing amounts of data,
resulting in terabytes of output data by a single machine. The analysis step, so called
protein identification, is used to bring insights into the sample data. The protein
identification is now a big data problem.
Task: Find protein identification solutions which use big data technology and map them to
the big data landscape.
