Genom åren har jag experimenterat en del med olika sätt att få studenterna mer aktiva på lektioner. På seminariet tänkte jag berätta om några av dessa erfarenheter. Jag är också mycket intresserad av att höra från andra om deras erfarenheter och tankar kring aktiv undervisning.https://www.chalmers.se/en/departments/math/calendar/Pages/Algebraisk-geometri211026.aspxhttps://www.chalmers.se/en/departments/math/calendar/Pages/Algebraisk-geometri211026.aspxSeminar in Algebraic Geometry and Number Theory<p>Euler, Skeppsgränd 3, och online</p><p>​Tobias Magnusson, Chalmers/GU: Numerical Evaluation of Holomorphic Eichler Integrals via Generalized Second Order Modular Forms</p>​<br />Abstract: Holomorphic Eichler integrals occur as the simplest case of iterated Eichler-Shimura integrals. Their numeric values appear in the experimental study of path integrals associated with Feynman diagrams. In this talk, we describe how to efficiently evaluate holomorphic Eichler integrals. We express them as linear combinations of products of generalized second order Eisenstein series, whose evaluation is a significantly simpler task. Generalized second order modular forms have their origins in earlier work by Mertens-Raum, Chinta-Diamantis-O'Sullivan, and Goldfeld. This project is joint work with Albin Ahlbäck and Martin Raum.https://www.chalmers.se/en/centres/chair/events/Pages/AI-Ethics-with-Dr-Beth-Singler.aspxhttps://www.chalmers.se/en/centres/chair/events/Pages/AI-Ethics-with-Dr-Beth-Singler.aspxAI Ethics with Dr Beth Singler<p>Online Zoom</p><p>​AI Ethics Online with Dr Beth Singler, Junior Researcher Fellow in Artificial Intelligence at Homerton College, University of Cambridge.</p><div><br /></div> 26 October 13:15–14:15<div><a href="https://ui.ungpd.com/Surveys/2e29e41d-49ac-455e-a0b5-98adf6a42cd4" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Register here</a><br />​<div><span><strong>Title:</strong> The Dreams our Stuff is Made of: Trust, Agency, and Super-agency.<br /><br /></span></div> <div><p><span lang="EN-GB">Drawing on ethnographic field work on the popular discourse around artificial intelligence, this talk will explore some of the implications of our imaginaries of AI. These imaginaries shape our relationship with these advances in technology, and impact the decisions we make about their influence on society, culture, and justice. This talk will provide case studies of particular ‘tension points’ around ideas of trust, agency, and even super-agency, and argue for the role of both public engagement and education in the larger ‘AI ethics’ debate.<br /><br /></span></p> <span><strong>Abstract: </strong><strong>Dr Beth Singler </strong>is the Junior Research Fellow in Artificial Intelligence at Homerton College, University of Cambridge.

These problems characterize critical points of energy minimization problems on the infinite-dimensional Stiefel manifold. To efficiently compute minimizers we propose a novel Riemannian gradient descent method induced by an energy-adaptive metric. Quantified convergence of the method is established under suitable assumptions on the underlying problem. A non-monotone line search and the inexact inexact evaluation of Riemannian gradients substantially improve the overall efficiency of the method. Numerical experiments illustrate the performance of the method and demonstrates its competitiveness with well-established  schemes.</p> <p>This is joint work with Robert Altmann (U Augsburg) and Tatjana Stykel (U Augsburg).</p>https://www.chalmers.se/en/departments/math/calendar/Pages/Computational211104.aspxhttps://www.chalmers.se/en/departments/math/calendar/Pages/Computational211104.aspxComputational and Applied Mathematics (CAM) seminar<p>MV:L14 and online</p><p>​Stefan Horst Sommer, University of Copenhagen: Stochastic shape analysis and probabilistic geometric statistics</p>​<br />Abstract: Analysis and statistics of shape variation can be formulated in geometric settings with geodesics modelling transitions between shapes. The talk will concern extensions of these smooth geodesic models to account for noise and uncertainty: Stochastic shape processes and stochastic shape matching algorithms. In the stochastic setting, matching algorithms take the form of bridge simulation schemes which also provide approximations of the transition density of the stochastic shape processes. The talk will cover examples of stochastic shape processes and connected bridge simulation algorithms. I will connect these ideas to geometric statistics, the statistical analysis of general manifold valued data, particularly to the diffusion meanhttps://www.chalmers.se/en/areas-of-advance/ict/calendar/Pages/Act-Sustainable-Can-automated-fact-checkers-clean-up-the-mess.aspxhttps://www.chalmers.se/en/areas-of-advance/ict/calendar/Pages/Act-Sustainable-Can-automated-fact-checkers-clean-up-the-mess.aspxAct Sustainable: Can automated fact checkers clean up the mess?<p>Studenternas Hus, Götabergsgatan 17, Göteborg</p><p>​Five days dedicated to sustainable development!

Transparency and interpretability of machine learning models is critical in high stakes decisions. However, there are clear reasons why organizations might use black box models instead: it is easier to profit from inexplicable predictive models than transparent models, and it is actually much easier to construct complicated models than interpretable models. Most importantly, there is a widely-held belief that that more accurate models must be more complicated, and more complicated models cannot possibly be understood by humans. Both parts of this last argument, however, are lacking in scientific evidence and are often not true in practice. There are many cases in which interpretable models are just as accurate as their black box counterparts on the same dataset, as long as one is willing to search carefully for such models. </font></p> <p class="chalmersElement-P"><font face="open sans"><br /></font></p> <p class="chalmersElement-P"><font face="open sans">In her talk, Dr. Rudin will discuss the interesting phenomenon that interpretable machine learning models are often as accurate as their black box counterparts, giving examples of such cases encountered throughout her career. One example she will discuss is predicting manhole fires and explosions in New York City, working with the power company. This was the project that ultimately drew Dr. Rudin to the topic of interpretable machine learning. This project was extremely difficult due to the complexity of the data, and interpretability was essential to her team’s ability to troubleshoot the model. In a second example, she will discuss how interpretable machine learning models can be used for extremely high stakes decisions, such as caring for critically ill patients in intensive care units of hospitals. Here, interpretable machine learning is used to predict seizures in patients being monitored with continuous electroencephalogram monitoring (cEEG). In a third example, she will discuss predicting criminal recidivism, touching upon the scandal surrounding the use of a black box model in the U.S. justice system, questioning whether we truly need such a model at all.</font></p></div> <div><h2 class="chalmersElement-H2" style="font-family:&quot;open sans&quot;;font-size:16px"><a href="https://youtu.be/1cap241NOkg"></a></h2> <span style="font-family:&quot;open sans&quot;;font-size:16px"></span><div style="font-family:&quot;open sans&quot;;font-size:16px"><br /></div> <span style="font-family:&quot;open sans&quot;;font-size:16px"></span><div style="font-family:&quot;open sans&quot;"><span style="font-family:&quot;open sans&quot;, sans-serif;font-size:20px">About the speaker</span><br /></div> <div><span style="font-family:&quot;open sans&quot;, sans-serif;font-size:20px"><img src="/SiteCollectionImages/Centrum/CHAIR/events/AI_Talks_CynthiaRudin.png" class="chalmersPosition-FloatLeft" alt="" style="margin-top:5px;margin-bottom:5px;margin-left:10px;height:232px;width:180px" /></span><font face="open sans">Cynthia Rudin is a professor of computer science, electrical and computer engineering, statistical science, and biostatistics &amp; bioinformatics at Duke University, and directs the Interpretable Machine Learning Lab (formerly the Prediction Analysis Lab).
