"Fire studenters opplevelser av bachelorprogrammet i kjemi og biokjemi"

The FARAON 2022 Conference provides a platform for young researchers to present, share, and discuss the latest and upcoming developments in Advanced Functional Materials with wide networking.

Deep learning (DL) has had unprecedented success and is now entering scientific computing with full force. However, current DL methods typically suffer from instability, even when universal approximation properties guarantee the existence of stable neural networks (NNs). In this talk we will show that there are basic well-conditioned problems in scientific computing where NNs with great approximation qualities are proven to exist, however, there does not exist any algorithm, even randomised, that can train (or compute) such a NN to even 1-digit of accuracy with a probability greater than 1/2. These results provide basic foundations for Smale’s 18th problem ("What are the limits of AI?") and imply a potentially vast classification theory describing conditions under which (stable) NNs with a given accuracy can be computed by an algorithm. We begin this theory by initiating a unified theory for compressed sensing and DL, leading to sufficient conditions for the existence of algorithms that compute stable NNs in inverse problems. We introduce Fast Iterative REstarted NETworks (FIRENETs), which we prove and numerically check (via suitable stability tests) are stable. The reference for this talk is: https://arxiv.org/abs/2101.08286 (to appear in Proc. Natl. Acad. Sci. USA).

We have encouraged students to develop their own physics problems, explore them and report on their results in the form of a computational essay in the course in elementary electromagnetism (Fys1120) from 2018 to 2021. In parallel we have developed new learning material and supporting exercises to provide students with sufficient skills and knowledge to succeed with an essay project. In 2021 the computational essay project was used as an extended home exam counting 50% towards the final grade.

In this talk, I will discuss experiences and reflections on the use of computational essays and how we plan to develop this activity in the coming years.

MN-fakultetet inviterer til informasjonsmøte om utveksling, der vi forteller deg hva du trenger å vite for å planlegge et semester i utlandet.

Exploring Probationary Academic Citizenship in the Swiss Context with Professor Nicky le Feuvre.

The Norwegian Environmental Chemistry Symposium Series builds upon a long lasting tradition of Norwegian conferences on environmental chemistry. After pausing of the conferences since 2013, they resurged as a continuous meeting series with NECS 2020 held in September 2020 in Loen, Norway. The new symposium series is organized under the auspices of the Norwegian Chemical Society´s Division for Analytical Chemistry.

Njord Seminar with Marcel Thielmann (University of Bayreuth): Crushed and fried: collaborative generation of deep earthquakes due to grain size reduction and shear heating

Ph.d.-kandidat Jing Sun ved Institutt for geofag, Det matematisk-naturvitenskapelige fakultet, vil forsvare avhandlingen Deep learning-based seismic data processing for attenuation of interference noise and deblending in the shot domain for graden Philosophiae Doctor.

Hylleraas seminar, hosted in Oslo

Dr Philos candidate Tore Qvenild at the Department of Biosciences will be defending the thesis "Climatic impact on the crustacean species Lepidurus arcticus, Gammarus lacustris and Eurycercus lamellatus on brown trout Salmo trutta production in a high mountain area in Southern Norway" for the degree of Dr Philos.

Abstract: The fungal kingdom is one of the most species-rich organismal groups, containing up to 6 million species worldwide with a large diversity of ecosystem functions. Multicellularity has evolved independently in fungi, and over time many different growth forms and structures have originated. I will present some basics on fungal growth and the formation of complex multicellular structures.

Online participation is possible too. Please contact "timokoch at uio.no" for the Zoom link. This talk is part of the Mechanics Lunch Seminar series. Bring-your-own-lunch and lots of questions.
