Since then, they have become a staple tool in generative modeling, representation learning, and unsupervised learning more broadly. Their use as analogues of human cognition is one of the first steps towards the understanding of more complex cognitive models leading up to models of human brain function and behavior. As part of a series of talks on cognitive science and deep learning at the realraum in Graz, this presentation will focus on the role of VAEs in cognitive science research. Topics: - Supervised vs. unsupervised learning - Deep Learning basics: classifiers and backpropagation - Autoencoders: architecture, training, embedding, and generative modeling - Variational Autoencoders: statistical latent space, and the reparametrization trick - Training VAEs: loss functions, optimization, and the KL divergence - Concept learning: VAEs in cognitive science https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://cfp.realraum.at/realraum-october/talk/LHH3M9/ Fri, 24 Oct 2025 19:00:00 +0200 https://cdn.media.ccc.de/contributors/realraum/h264-hd/realraum-1-eng-Variational_Autoencorders_the_cognitive_scientists_favorite_deep_learning_tool_hd.mp4?1761419467 2b135a57-c750-5084-9d3b-28391b586e87 2025-10-24T19:00:00+02:00 Xiutik No 1, 2025, realraum, LoTHR, LoTHR, realraum-eng, realraum, r3, r3talks, graz, Day 1 Variational Autoencoders (VAEs) were first introduced as early concept learners in the vision domain.

Es wird ein Überblick geschaffen, wie man vom einfachen Complementary Filter zum Kalman Filter kommt und wie man diesen adaptiert um nichtlineare Zustände zu berechnen. Diese Erweiterung ist als Extended Kalman Filter bekannt, die in den meisten Anwendung der Navigation und Orientierungsbestimmungen von Flugzeugen zum Einsatz kommt. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de Thu, 25 Sep 2025 19:15:00 +0200 https://cdn.media.ccc.de/contributors/realraum/h264-hd/realraum-56371-deu-Kalman_Filter_und_Sensor_Fusion_hd.mp4?1758883514 3dfa1cff-44d5-43c9-ac1c-9d72a0beaba7 2025-09-25T19:15:00+02:00 Christian Hartler No 56371, 2025, realraum, LoTHR, realraum-deu, realraum, r3, r3talks, graz, Day 3 Ein kurzer Vortrag, der die Vor- und Nachteile einzelner Sensoren aufzeigt, was die Entwicklung der Sensor Fusion motivierte.

Well, that’s exactly what this project was all about! With a mix of DIY repairs, scavenged parts, and a whole lot of learning, the API2000 tandem mass spectrometer got a second chance. From fixing a corroded interface heater to tracking down the right software (hello, Windows XP nostalgia!), every step was a challenge. But in the end, the first tests were a success – including injecting coffee to confirm the presence of caffeine (because, of course, coffee had to be involved). The journey doesn’t stop here. Next steps? Diving into deeper mathematical concepts, experimenting with blood analysis, and pushing the API2000 to its limits. about this event: https://gry.sh/posts/dgms2025/ Fri, 04 Apr 2025 21:00:00 +0200 https://cdn.media.ccc.de/contributors/realraum/h264-hd/import-56370-eng-DIY_Revival_of_an_API_2000_Tandem_Mass_Spectrometer_hd.mp4?1757065350 6b097c7a-c3cf-44da-bb53-aaa103deff9e 2025-04-04T21:00:00+02:00 Sally No 56370, 2025, realraum, LoTHR, realraum-eng Ever wondered if you could bring an old mass spectrometer back to life?
