During the workshop, we will review and explain the main steps of a machine learning-based computer vision project, from problem definition to image acquisition, annotation, training, validation, and inference. We will illustrate these steps in a practical way, by building a real computer vision application together until we can run it live on a camera. Along the way, we will discuss important concepts (data drift, overfitting, data augmentation) and observe how they manifest themselves in practice. We will also share tips and tricks to help you tackle your own computer vision challenges.<br>\r\n<br>\r\n<strong>Prerequisites:</strong><br>\r\nBasic familiarity with Python, image analysis, and machine learning concepts is desirable, but not strictly necessary.<br>\r\n<br>\r\n<strong>Level:</strong> <br>\r\nBeginner / Intermediate<br>\r\n ", "image_description": "", "creation_date": "2026-01-30T11:40:06", "last_modification_date": "2026-01-30T11:40:06", "link_label": "Registration", "link_url": "https://docs.google.com/forms/d/e/1FAIpQLSc1NukuuzIzzMnbDZkfudvj1M7wDJY6JeWQKoQrcl1ZIVFcUw/viewform?usp=header", "canceled": "False", "cancel_reason": "", "place_and_room": "CE 1 711.2", "url_place_and_room": "https://plan.epfl.ch/?room==CE%201%20711.2", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "<a href=\"https://people.epfl.ch/mallory.wittwer?lang=en\">Mallory Witwer</a>", "organizer": "<a href=\"https://imaging.epfl.ch/\">Center for Imaging</a>", "contact": "<a href=\"https://people.epfl.ch/cecilia.carron?lang=fr\">Cecilia Carron</a>", "is_internal": "False", "theme": "", "vulgarization": { "id": 1, "fr_label": "Tout public", "en_label": "General public" }, "registration": { "id": 1, "fr_label": "Sur inscription", "en_label": "Registration required" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/119528/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/1/?format=api", "https://memento.epfl.ch/api/v1/mementos/4/?format=api", "https://memento.epfl.ch/api/v1/mementos/5/?format=api", "https://memento.epfl.ch/api/v1/mementos/6/?format=api", "https://memento.epfl.ch/api/v1/mementos/8/?format=api", "https://memento.epfl.ch/api/v1/mementos/9/?format=api", "https://memento.epfl.ch/api/v1/mementos/284/?format=api", "https://memento.epfl.ch/api/v1/mementos/27/?format=api" ] }, { "id": 71068, "title": "Herzog & ....

Rice paddy soils are rich in organic carbon, and the conventional understanding has been that organic carbon enhances microbial arsenic methylation by fueling microbial activity. This presentation will describe a series of recent investigations — spanning pure culture to greenhouse-scale experiments — that challenge this conceptual model. First, the presentation will describe the role of carbon catabolite repression (CCR) in regulating cellular uptake and subsequent enzymatic methylation of arsenite. A combination of biosensor, gene expression, and arsenic speciation analyses demonstrate that sugars lead to CCR and a decrease in arsenic methylation, while low molecular weight organic acids do not impact arsenite uptake. The presentation will then examine couplings between methanogenesis and arsenic demethylation, wherein a greater abundance of methylotrophic carbon substrates (methanol, methylamines) promote arsenic demethylation by methanogens and limit the accumulation of methylated arsenic compounds. A genome-resolved metatranscriptomic analysis of anaerobic soil slurry experiments resolved links between methylotrophic substrate utilization and arsenic demethylation, while greenhouse experiments showed that higher levels of methanogenesis in soils were associated with lower concentrations of methylated arsenic in rice grains. Taken together, these results provide a more nuanced understanding of how utilization of distinct carbon substrates impacts arsenic methylation-demethylation dynamics, and provides mechanistic insights into how paddy soil management practices influence arsenic speciation in rice.</div>\r\n</div>\r\n</div>\r\n<br>\r\n<br>\r\n<br>\r\n<strong>Biography:</strong>\r\n\r\n<div class=\"page\">\r\n<div class=\"layoutArea\">\r\n<div class=\"column\">Dr. Matthew Reid is an associate professor in the School of Civil and Environmental Engineering at Cornell University and directs the Biogeochemistry and Ecosystem Engineering Research Group.

Their stability and eventual breakdown influence wake dynamics, mixing processes, and overall flow performance. This seminar presents two recent studies exploring vortex stability and vortex breakdown.<br>\r\nPart I – Short-wave instability of a helical vortex<br>\r\nThe first part of the seminar discusses the short-wave instability of a helical vortex generated by a rotating blade. Combining experimental dye visualisations, numerical simulations, and theoretical analysis, the study identifies displacement perturbations whose wavelengths are small relative to the helix radius and pitch but may remain large compared with the vortex core size. Stability analysis based on experimentally measured vortex profiles reveals broad bands of unstable wavenumbers for several vortex bending modes. These results differ from predictions of existing theories for short-wave vortex instability. Similar instability modes are also observed in arrays of straight vortices, indicating that the phenomenon is not related to vortex curvature. A theoretical examination of the dispersion relation of Kelvin modes for the measured vortex profiles uncovers a previously unidentified family of modes associated with the specific vorticity distribution. Their non-resonant interaction through the strain field provides a plausible explanation for the experimentally observed instability features.<br>\r\nPart II – Two-phase wing-tip vortex breakdown<br>\r\nThe second part presents the discovery of a new flow feature observed in the wake of a rectangular wing in water: the breakdown of the wing-tip vortex triggered by the injection of air into the vortex core downstream of the wing. Experiments show that, for certain combinations of Reynolds number and angle of attack, a stationary air bubble becomes trapped within the vortex core at a finite distance behind the wing and can persist for several minutes even after the air injection is stopped. Under different conditions, the bubble may drift upstream or downstream, or it may disintegrate immediately. Measurements of bubble properties and vortex characteristics reveal that the breakdown behaviour depends primarily on the vortex circulation and on the axial flow component within the core. The formation of a stable breakdown bubble occurs only when a velocity excess relative to the free stream is present.<br>\r\nThe two studies highlight new mechanisms governing the stability and transformation of vortical flows, offering insight into the dynamics of vortex instabilities and vortex-core modifications in fluid systems.<br>\r\n<br>\r\n<br>\r\n<strong>Biography</strong><br>\r\nThomas Leweke graduated from RWTH Aachen University in Germany in 1990 with a “Diplom” (Master) in Physics.
