Automated Machine Learning For Computational Mechanics (Dagstuhl Seminar 24282)
No full textMachine learning (ML) has achieved undeniable success in computational mechanics, an ever-growing discipline that impacts all areas of engineering, from structural and fluid dynamics to solid mechanics and vehicle simulation. Computational mechanics uses numerical models and time- and resource-consuming simulations to reproduce physical phenomena, usually with the goal of optimizing the parameter configuration of the model with respect to the desired properties of the system. ML algorithms enable the construction of surrogate models that approximate the outcome of the simulations, allowing faster identification of well-performing configurations. However, determining the best ML approach for a given task is not straightforward and depends on human experts. Automated machine learning (AutoML) aims to reduce the need for experts to obtain effective ML pipelines. It provides off-the-shelf solutions that can be used without prior knowledge of ML, allowing engineers to spend more time on domain-specific tasks. AutoML is underutilized in computational mechanics; there is almost no communication between the two communities, and engineers spend unnecessary effort selecting and configuring ML algorithms. Our Dagstuhl Seminar aimed to (i) raise awareness of AutoML in the computational mechanics community, (ii) discover strengths and challenges for applying AutoML in practice, and (iii) create a bilateral exchange so that researchers can mutually benefit from their complementary goals and needs
Human-Centered Approaches for Provenance in Automated Data Science (Dagstuhl Seminar 23372)
No full textThe scope of automated machine learning (AutoML) technology has extended beyond its initial boundaries of model selection and hyperparameter tuning and towards end-to-end development and refinement of data science pipelines. These advances, both theoretical and realized, make the tools of data science more readily available to domain experts that rely on low- or no-code tooling options to analyze and make sense of their data. To ensure that automated data science technologies are applied both effectively and responsibly, it becomes increasingly urgent to carefully audit the decisions made both automatically and with guidance from humans.
This Dagstuhl Seminar examines human-centered approaches for provenance in automated data science. While prior research concerning provenance and machine learning exists, it does not address the expanded scope of automated approaches and the consequences of applying such techniques at scale to the population of domain experts. In addition, most of the previous works focus on the automated part of this process, leaving a gap on the support for the sensemaking tasks users need to perform, such as selecting the datasets and candidate models and identifying potential causes for poor performance.
The seminar brought together experts from across provenance, information visualization, visual analytics, machine learning, and human-computer interaction to articulate the user challenges posed by AutoML and automated data science, discuss the current state of the art, and propose directions for new research. More specifically, this seminar:
- articulates the state of the art in AutoML and automated data science for supporting the provenance of decision making,
- describes the challenges that data scientists and domain experts face when interfacing with automated approaches to make sense of an automated decision,
- examines the interface between data-centric, model-centric, and user-centric models of provenance and how they interact with automated techniques, and
- encourages exploration of human-centered approaches; for example leveraging visualization
Author Functions in Lars Kepler\u27s The Hypnotist: An Analysis
No full textThis paper examines Foucault\u27s notion of the author function as it pertains to Lars Kepler\u27s bestselling 2011 crime thriller, The Hypnotist. Lars Kepler is the pseudonym of a Swedish husband-wife writing duo, making him the perfect subject for analysis centering on illusory notion of the author. This paper will answer these questions: Who is the true author of The Hypnotist? What factors influence the author function of this bestelling novel? And what can The Hypnotist phenomenon tell us about the relationships between authors and their readers? This paper will demonstrate that no literary works may be ascribed to an individual person, and that authors hold no privileged knowledge of the works they produce, because authors cease to be authors the moment pen is lifted from page
ICON loop carpooling show case
No full textIn this chapter we describe a proactive carpooling service that combines induction and optimization mechanisms to maximize the impact of carpooling within a community. The approach autonomously infers the mobility demand of the users through the analysis of their mobility traces (i.e. Data Mining of GPS trajectories) and builds the network of all possible ride sharing opportunities among the users. Then, the maximal set of carpooling matches that satisfy some standard requirements (maximal capacity of vehicles, etc.) is computed through Constraint Programming models, and the resulting matches are proactively proposed to the users. Finally, in order to maximize the expected impact of the service, the probability that each carpooling match is accepted by the users involved is inferred through Machine Learning mechanisms and put in the CP model. The whole process is reiterated at regular intervals, thus forming an instance of the general ICON loop
”Lärda nyheter” i Peter Hernquists korrespondens till Carl von Linné och Abraham Bäck - med kommentarer och utvikningar
No full textI detta Meddelande nr 55 från Veterinärhistoriska museet har författaren - professor emeritus Lars-Erik Appelgren - gjort ett urval av den korrespondens som Peter Hernquist hade med sina mentorer Carl von Linné och Abraham Bäck under sin vistelse i Frankrike, varvid ”Lärda nyheter” varit en ledstjärna för urvalet. Speciellt har breven till Bäck försetts med författarens personliga kommentarer men även kompletterats med faktaupplysningar från andra källor än breven om berörda nyheter. För att underlätta läsningen har dessa kommentarer omgetts med enkelkonturerad och utvikningarna med dubbelkonturerad ram. Lars-Erik Appelgren har inte bara genom sitt veterinärhistoriska författarskap utan också genom att ställa sina fackliga kunskaper och sin eminenta estetiska läggning till förfogande gjort Veterinärhistoriska museet ovärderliga tjänster. Det är med stor glädje jag noterar att region Uppsala nyligen visat sin uppskattning genom att tilldela Lars-Erik sitt Medicinhistoriska stipendium med motiveringen att de vill ”lyfta fram ett viktigt men ofta förbisett område inom medicinhistorien: veterinärmedicinen”. Med de varmaste gratulationer
Interpreting Wage Bargaining Norms
No full textFrom the mid-1990s onwards, Swedish wage bargaining has been characterised by informal co-ordination of the wage claims of big unions and bargaining cartels. In particular, it has been understood that the manufacturing sector should lead by first agreeing on a pay increase, whereafter the service sector and public sector unions choose a similar increase. We analyse his setup with two possible theoretical interpretations: (i) the manufacturing sector as a tackelberg leader and (ii) a normative role for the manufacturing sector’s pay increase, upported either by unmodelled social pressure or a modeled loss aversion (envy) of the heltered sector unions. The conclusion of the analysis is that the normative or leading role of one sector – in the Swedish case the manufacturing sector – can potentially bring big benefits for employment and output. Generalising an idea suggested by Lars Calmfors and Anna Larsson, our analysis also generates a rudimentary theory of why the wage increase norm sometimes binds and sometimes not. A comparison of the model predictions and the observed outcomes of the last five wage bargaining rounds in Sweden suggests that the model is generally consistent with the empirical observations: wage moderation and norm observance are stronger when the manufacturing industry’s initial relative wage is low.wage bargaining; bargaining co-ordination
