Given a few assumptions, we argue that it will encounter a fundamental ambiguity in the data about its goal. </div> <div><br /></div> <div>For example, if we provide a large reward to indicate that something about the world is satisfactory to us, it may hypothesize that what satisfied us was the sending of the reward itself; no observation can refute that. Then we argue that this ambiguity will lead it to intervene in whatever protocol we set up to provide data for the agent about its goal. We discuss an analogous failure mode of approximate solutions to assistance games, and review some recent approaches that may avoid this problem.</div> <div>This is joint work with Marcus Hutter and Michael Osborne.</div> <br /><div><strong>Michael Cohen</strong> is studying for a DPhil in Engineering Science at the University of Oxford. His research considers the expected behavior of generally intelligent artificial agents, and he is interested in designing agents that we can expect to behave safely.</div> <div><br /></div> <a href="" target="_blank"><div><br /></div> <div>Register here to receive the link to the seminar</div></a><div><br /></div>’s and bachelor’s thesis fair in health and technology<p>Lecture Hall Palmstedt, university building, Chalmersplatsen 2, Campus Johanneberg</p><p>On 12 October it is time for the autumn’s physical master’s thesis fair, this time at Chalmers.

Consequently, they have already become the main building block for numerous algorithms and practical applications. This talk will contrast the most commonly used generative models to date with a particular focus on denoising diffusion probabilistic models, the core of the currently leading approaches to visual synthesis. Despite their enormous potential, these models come with their own specific limitations. We will then discuss a solution, latent diffusion models a.k.a. &quot;Stable Diffusion&quot;, that significantly improves the efficiency of diffusion models. Now billions of training samples can be summarized in compact representations of just a few gigabyte so that the approach runs on even consumer GPUs. Time permitting, the talk will conclude with an outlook on current extensions and future work.<span><br /></span></span></div> <div><span><span><br /></span></span></div> <div><strong>Short Bio:</strong></div> Björn Ommer is a full professor at the University of Munich where he is heading the Machine Vision and Learning Group.

In September, 2022 we announced that we have also opened a new lab in Berlin, Germany.</div> <div><br /></div> <div>In this talk I will first discuss the research areas that we are currently exploring in AI4Science at Microsoft Research in Cambridge (UK), Amsterdam and in our new lab in Berlin, covering topics such as drug discovery, material generation, neural PDE solvers, electronic structure theory and computational catalysis.</div> <div><br /></div> <div>Then I will dive a little deeper into our recent work on Clifford Neural layers for PDE modeling. The PDEs of many physical processes describe the evolution of scalar and vector fields. In order to take into account the correlation between these different fields and their internal components, we represent these fields as multivectors, which consist of scalar, vector, as well as higher-order components. Their algebraic properties, such as multiplication, addition and other arithmetic operations can be described by Clifford algebras, which we use to design Clifford convolutions and Clifford Fourier transforms.</div> <div><br /></div> <div>We empirically evaluate the benefit of Clifford neural layers by replacing convolution and Fourier operations in common neural PDE surrogates by their Clifford counterparts on two-dimensional Navier-Stokes and weather modeling tasks, as well as three-dimensional Maxwell equations.</div> <div><br /></div> <div>If time permits, I will briefly cover very recent work on protein structure prediction and coarse graining molecular dynamics.</div> <br /><div><strong>Rianne van den Berg</strong> is a Principal Researcher at Microsoft Research Amsterdam, where she works as part of the AI4Science team on the intersection of deep learning and computational chemistry.

The energy transformation from fossil fuels to renewable sources has significant challenges due to raw material shortages. International Energy Agency has an ambitious target to reach photovoltaic (PV) solar panel capacity that covers more than 20% of the global energy demand. Although policymakers and manufacturers draw a bright future, natural source limitation is a nightmare for PV technology. Additionally, end-of-life solar panels will dramatically affect the waste stream, and currently, there is no sustainable recycling for their waste. </div> <div>Our research maps the critical metals for PV industry and their circularity and developing recycling processes of these metals from manufacturing and end-of-life waste. The analysis clearly showed that silver, indium, and gallium supplies are the bottlenecks of the industry due to resource limitations and the importance of the other industrial applications of these metals. Although recycling critical metals from production waste requires straightforward processes, there are still technical and economical challenges to implementation. Considering end-of-life PV modules, their recycling requires a com​bination of mechanical, pyrometallurgical and hydrometallurgical processing approaches. </div> <div><br /></div> <div><br /></div> <div><a href="/en/staff/Pages/Burcak-Ebin.aspx">Dr. Burcak Ebin​</a>, <span style="background-color:initial">Associate Professor, Department of Chemistry and Chemical Engineering, Industrial Materials Recycling, </span><span style="background-color:initial">is working on recycling of alkaline, NiMH and Li-ion battery waste by pyrometallurgical processes.
