Abstract:
In this talk, the audience will have an opportunity to familiarise with the concept of technical debt in Machine Learning. In order to properly diagnose the problems and enquiries from stakeholders, creators and maintainers of ML systems need to be aware not only of their part of the system but all the interactions it has, from the incoming data. Unlike in software development, it is not possible to create strict abstraction layers as Machine Learning systems are heavily dependent on the data that they are created on. Certain problems arise when after the first deployment of the new ML system is starts to alter the data that is then labelled and used to refresh it. There are also some benefits of using rules for events that are important but very rare to be reflected in ML model (imagine the system that tries to prevent some things that could happen but so far never happened). Such rule-based system can also be used for feature extraction. All things considered, it leads to interactions between rules and model that are forming a decision cascade in some form of a complicated graph, where at first rules are used to create features and then to override ML system decision in specific cases. All of the cases will be illustrated with real-life examples from the author's professional experience and advice on how they could be addressed.

Abstract
Scenarios of human-computer interaction help us to
understand and to create computer systems and
applications as artifacts of human activity Ñas things to
learn from, as tools to use in one's work, as media for
interacting with other people. Scenario-based design of
information technology addresses five technical
challenges: Scenarios evoke reflection in the content of
design work, helping developers coordinate design action
and reflection. Scenarios are at once concrete and flexible,
helping developers manage the fluidy of design situations.
Scenarios afford multiple views of an interaction, diverse
kinds and amounts of detailing, helping developers
manage the many consequences entailed by any given
design move. Scenarios can also be abstracted and
categorized, helping designers to recognize, capture, and
reuse generalizations, and to address the challenge that
technical knowledge often lags the needs of technical
design. Finally, scenarios promote work-oriented
communication among stakeholders, helping to make
design activities more accessible to the great variety of
expertise that can contribute to design, and addressing the
challenge that external constraints designers and clients
often distract attention from the needs and concerns of the
people who will use the technology.
1. Introduction
Designers of information systems and applications face
a disturbing reality. While there is plenty of opportunity
to do things that make a difference, it is never unequivocal
just what should be done, or even just what the real
problems are. The problems can only be definitively
analyzed by being solved; the appropriate solution
methods must typically be executed in order to be
identified; the solutions must be implemented in order to
be specified. All the while, the designer faces convoluted
networks of tradeoff and interdependency, the potential of
0-7695-0001-3/99 $10
untoward impacts on people and their social institutions,
and the likelihood that changing cultural and technological
circumstances will obviate any solution before it can be
deployed.
Most software engineering methods belong to a
methodological tradition that seeks to control the
complexity and fluidity of design through techniques that
filter the information considered and decompose the
problems to be solved. A complementary tradition seeks
to exploit the complexity and fluidity of design by trying
to learn more about the structure and dynamics of the
problem domain, by trying to see the situation in many
different ways, and by interacting intimately with the
concrete elements of the situ ...

Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

Grote partijen zijn al een tijdje onderweg met retail media. Ondertussen worden in dit domein ook de kansen zichtbaar voor andere spelers in de markt. Maar met die kansen ontstaan ook vragen: Zelf retail media worden of erop adverteren? In welke fase van de funnel past het en hoe integreer je het in een mediaplan? Wat is nu precies het verschil met marketplaces en Programmatic ads? In dit half uur beslechten we de dilemma's en krijg je antwoorden op wanneer het voor jou tijd is om de volgende stap te zetten.
