Wittgenstein and Communication Technology : A conversation between Richard Harper and Constantine Sandis
Special Issue: PROCEEDINGS OF THE BRITISH WITTGENSTEIN SOCIETY 10TH ANNIVERSARY CONFERENCE: WITTGENSTEIN IN THE 21ST CENTURY © 2018 John Wiley & Sons LtdThis paper documents a conversation between a philosopher and a human computer interaction researcher whose research has been enormously influenced by Wittgenstein. In particular, the in vivo use of categories in the design of communications and AI technologies are discussed, and how this meaning needs to evolve to allow creative design to flourish. The paper will be of interest to anyone concerned with philosophical tools in everyday action.Non peer reviewe
Designerly Tools
An assumption behind this paper is that research aimed at improving interaction design practice is not as successful as it could be. We will argue that one reason for this is that the understanding of what constitutes designerly tools is not enough recognized among those who propose new tools for interaction design. We define designerly tools as methods, tools, techniques, and approaches that support design activity in way that is appreciated by practicing interaction designers. Based on a two empirical studies, we have developed a framework and a way of studying designers and their tools. We discuss some insights about what characterizes designerly tools and what kind of implications these insights might have for the further development of tools aimed at supporting design practice.

Inverse Classification for Comparison-based Interpretability in Machine Learning
In the context of post-hoc interpretability, this paper addresses the task of
explaining the prediction of a classifier, considering the case where no
information is available, neither on the classifier itself, nor on the
processed data (neither the training nor the test data). It proposes an
instance-based approach whose principle consists in determining the minimal
changes needed to alter a prediction: given a data point whose classification
must be explained, the proposed method consists in identifying a close
neighbour classified differently, where the closeness definition integrates a
sparsity constraint. This principle is implemented using observation generation
in the Growing Spheres algorithm. Experimental results on two datasets
illustrate the relevance of the proposed approach that can be used to gain
knowledge about the classifier.Comment: preprin
The Grammar of Interactive Explanatory Model Analysis
The growing need for in-depth analysis of predictive models leads to a series
of new methods for explaining their local and global properties. Which of these
methods is the best? It turns out that this is an ill-posed question. One
cannot sufficiently explain a black-box machine learning model using a single
method that gives only one perspective. Isolated explanations are prone to
misunderstanding, which inevitably leads to wrong or simplistic reasoning. This
problem is known as the Rashomon effect and refers to diverse, even
contradictory interpretations of the same phenomenon. Surprisingly, the
majority of methods developed for explainable machine learning focus on a
single aspect of the model behavior. In contrast, we showcase the problem of
explainability as an interactive and sequential analysis of a model. This paper
presents how different Explanatory Model Analysis (EMA) methods complement each
other and why it is essential to juxtapose them together. The introduced
process of Interactive EMA (IEMA) derives from the algorithmic side of
explainable machine learning and aims to embrace ideas developed in cognitive
sciences. We formalize the grammar of IEMA to describe potential human-model
dialogues. IEMA is implemented in the human-centered framework that adopts
interactivity, customizability and automation as its main traits. Combined,
these methods enhance the responsible approach to predictive modeling.Comment: 17 pages, 10 figures, 3 table
How Can Speech Recognisers Help Applied Research in the Civil Engineering, Transport and Related Industries
BACKGROUND
Speech recognition technology is rapidly advancing to the point here it can be usefully applied in a wide range of mtexts. For applications within the SERC Environment Committee's area of interest -civil engineering; construction; building; transport; water resources there are a number of kinds of recording situation in which one needs to keep one's eyes on the situation being studied; or in which the recording conditions (eg moving around with instruments) are unfavourable. The limitations of conventional pen and paper recording for these situations are obvious; and the limitations of hand-held data capture devices are also becoming apparent. Speech is therefore an easier medium to use; and a tape recorder a convenient means of recording the observations. For well defined recording tasks; speech recognisers might be a helpful way of transcribing the record. This seminar was convened to enable those who are potentially interested in such an application of information technology to hear of the latest developnents and assessments of the suitability of the technology
A Thousand Invisible Cords Binding Astronomy and High-Energy Physics
The traditional realm of astronomy is the observation and study of the
largest objects in the Universe, while the traditional domain of high-energy
physics is the study of the smallest things in nature. But these two sciences
concerned with opposite ends of the size spectrum are, in Muir's words, bound
fast by a thousand invisible cords that cannot be broken. In this essay I
propose that collaborations of astronomers and high-energy physicists on common
problems are beneficial for both fields, and that both astronomy and
high-energy physics can advance by this close and still growing relationship.
Dark matter and dark energy are two of the binding cords I will use to
illustrate how collaborations of astronomers and high-energy physicists on
large astronomical projects can be good for astronomy, and how discoveries in
astronomy can guide high-energy physicists in their quest for understanding
nature on the smallest scales. Of course, the fields have some different
intellectual and collaborative traditions, neither of which is ideal. The
cultures of the different fields cannot be judged to be right or wrong; they
either work or they don't. When astronomers and high-energy physicists work
together, the binding cords can either encourage or choke creativity. The
challenge facing the astronomy and high-energy physics communities is to adopt
the best traditions of both fields. It is up to us to choose wisely.Comment: Why "Fundamentalist" Physics Is Good for Astronomy (in response to
