text: "In the proposal for our CRC in 2011, we formulated a vision of markets for\r\nIT
services that describes an approach to the provision of such services\r\nthat
was novel at that time and, to a large extent, remains so today:\r\n„Our vision
of on-the-fly computing is that of IT services individually and\r\nautomatically
configured and brought to execution from flexibly combinable\r\nservices traded
on markets. At the same time, we aim at organizing\r\nmarkets whose participants
maintain a lively market of services through\r\nappropriate entrepreneurial actions.“\r\nOver
the last 12 years, we have developed methods and techniques to\r\naddress problems
critical to the convenient, efficient, and secure use of\r\non-the-fly computing.
Among other things, we have made the description\r\nof services more convenient
by allowing natural language input,\r\nincreased the quality of configured services
through (natural language)\r\ninteraction and more efficient configuration processes
and analysis\r\nprocedures, made the quality of (the products of) providers in
the\r\nmarketplace transparent through reputation systems, and increased the\r\nresource
efficiency of execution through reconfigurable heterogeneous\r\ncomputing nodes
and an integrated treatment of service description and\r\nconfiguration. We have
also developed network infrastructures that have\r\na high degree of adaptivity,
scalability, efficiency, and reliability, and\r\nprovide cryptographic guarantees
of anonymity and security for market\r\nparticipants and their products and services.\r\nTo
demonstrate the pervasiveness of the OTF computing approach, we\r\nhave implemented
a proof-of-concept for OTF computing that can run\r\ntypical scenarios of an OTF
market. We illustrated the approach using\r\na cutting-edge application scenario
– automated machine learning (AutoML).\r\nFinally, we have been pushing our work
for the perpetuation of\r\nOn-The-Fly Computing beyond the SFB and sharing the
expertise gained\r\nin the SFB in events with industry partners as well as transfer
projects.\r\nThis work required a broad spectrum of expertise. Computer scientists\r\nand
economists with research interests such as computer networks and\r\ndistributed
algorithms, security and cryptography, software engineering\r\nand verification,
configuration and machine learning, computer engineering\r\nand HPC, microeconomics
and game theory, business informatics\r\nand management have successfully collaborated
here."

text: Testing is one of the most frequent means of quality assurance for software.
Property-based testing aims at generating test suites for checking code against
user-defined properties. Test input generation is, however, most often independent
of the property to be checked, and is instead based on random or user-defined
data generation.In this paper, we present property-driven unit testing of functions
with numerical inputs and outputs. Alike property-based testing, it allows users
to define the properties to be tested for. Contrary to property-based testing,
it also uses the property for a targeted generation of test inputs. Our approach
is a form of learning-based testing where we first of all learn a model of a given
black-box function using standard machine learning algorithms, and in a second
step use model and property for test input generation. This allows us to test
both predefined functions as well as machine learned regression models. Our experimental
evaluation shows that our property-driven approach is more effective than standard
property-based testing techniques.

text: "In recent years, we observe an increasing amount of software with machine
learning components being deployed. This poses the question of quality assurance
for such components: how can we validate whether specified requirements are fulfilled
by a machine learned software? Current testing and verification approaches either
focus on a single requirement (e.g., fairness) or specialize on a single type
of machine learning model (e.g., neural networks).\r\nIn this paper, we propose
property-driven testing of machine learning models. Our approach MLCheck encompasses
(1) a language for property specification, and (2) a technique for systematic
test case generation. The specification language is comparable to property-based
testing languages. Test case generation employs advanced verification technology
for a systematic, property dependent construction of test suites, without additional
user supplied generator functions. We evaluate MLCheck using requirements and
data sets from three different application areas (software\r\ndiscrimination,
learning on knowledge graphs and security). Our evaluation shows that despite
its generality MLCheck can even outperform specialised testing approaches while
having a comparable runtime"

abstract:

text: "For optimal placement and orchestration of network services, it is crucial\r\nthat
their structure and semantics are specified clearly and comprehensively\r\nand
are available to an orchestrator. Existing specification approaches are\r\neither
ambiguous or miss important aspects regarding the behavior of virtual\r\nnetwork
functions (VNFs) forming a service. We propose to formally and\r\nunambiguously
specify the behavior of these functions and services using\r\nQueuing Petri Nets
(QPNs). QPNs are an established method that allows to\r\nexpress queuing, synchronization,
stochastically distributed processing delays,\r\nand changing traffic volume and
characteristics at each VNF. With QPNs,\r\nmultiple VNFs can be connected to complete
network services in any structure,\r\neven specifying bidirectional network services
containing loops.\r\n We discuss how management and orchestration systems can
benefit from our\r\nclear and comprehensive specification approach, leading to
better placement of\r\nVNFs and improved Quality of Service. Another benefit of
formally specifying\r\nnetwork services with QPNs are diverse analysis options,
which allow valuable\r\ninsights such as the distribution of end-to-end delay.
We propose a tool-based\r\nworkflow that supports the specification of network
services and the automatic\r\ngeneration of corresponding simulation code to enable
an in-depth analysis of\r\ntheir behavior and performance."

text: In machine learning, so-called nested dichotomies are utilized as a reduction
technique, i.e., to decompose a multi-class classification problem into a set
of binary problems, which are solved using a simple binary classifier as a base
learner. The performance of the (multi-class) classifier thus produced strongly
depends on the structure of the decomposition. In this paper, we conduct an empirical
study, in which we compare existing heuristics for selecting a suitable structure
in the form of a nested dichotomy. Moreover, we propose two additional heuristics
as natural completions. One of them is the Best-of-K heuristic, which picks the
(presumably) best among K randomly generated nested dichotomies. Surprisingly,
and in spite of its simplicity, it turns out to outperform the state of the art.

text: "Over the years, Design by Contract (DbC) has evolved as a\r\npowerful concept
for program documentation, testing, and verification.\r\nContracts formally specify
assertions on (mostly) object-oriented programs:\r\npre- and postconditions of
methods, class invariants, allowed call\r\norders, etc. Missing in the long list
of properties specifiable by contracts\r\nare, however, method correlations: DbC
languages fall short on stating\r\nassertions relating methods.\r\nIn this paper,
we propose the novel concept of inter-method contract,\r\nallowing precisely for
expressing method correlations.We present JMC as\r\na language for specifying
and JMCTest as a tool for dynamically checking\r\ninter-method contracts on Java
programs. JMCTest fully automatically\r\ngenerates objects on which the contracted
methods are called and\r\nthe validity of the contract is checked. Using JMCTest,
we detected\r\nthat large Java code bases (e.g. JBoss, Java RT) frequently violate
standard\r\ninter-method contracts. In comparison to other verification tools\r\ninspecting
(some) inter-method contracts, JMCTest can find bugs that\r\nremain undetected
by those tools."

text: 'Whenever customers have to decide between different instances of the same
product, they are interested in buying the best product. In contrast, companies
are interested in reducing the construction effort (and usually as a consequence
thereof, the quality) to gain profit. The described setting is widely known as
opposed preferences in quality of the product and also applies to the context
of service-oriented computing. In general, service-oriented computing emphasizes
the construction of large software systems out of existing services, where services
are small and self-contained pieces of software that adhere to a specified interface.
Several implementations of the same interface are considered as several instances
of the same service. Thereby, customers are interested in buying the best service
implementation for their service composition wrt. to metrics, such as costs, energy,
memory consumption, or execution time. One way to ensure the service quality is
to employ certificates, which can come in different kinds: Technical certificates
proving correctness can be automatically constructed by the service provider and
again be automatically checked by the user. Digital certificates allow proof of
the integrity of a product. Other certificates might be rolled out if service
providers follow a good software construction principle, which is checked in annual
audits. Whereas all of these certificates are handled differently in service markets,
what they have in common is that they influence the buying decisions of customers.
In this paper, we review state-of-the-art developments in certification with respect
to service-oriented computing. We not only discuss how certificates are constructed
and handled in service-oriented computing but also review the effects of certificates
on the market from an economic perspective.'
