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": 71250, "title": "MechE Colloquium: When Materials Bend the Rules: Buckling Response of Slender Structures Born of Constitutive Nonlinearities", "slug": "meche-colloquium-when-materials-bend-the-rules-buc", "event_url": "https://memento.epfl.ch/event/meche-colloquium-when-materials-bend-the-rules-buc", "visual_url": "https://memento.epfl.ch/image/32609/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/32609/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/32609/max-size.jpg", "lang": "en", "start_date": "2026-04-14", "end_date": "2026-04-14", "start_time": "12:00:00", "end_time": "13:00:00", "description": "<strong>Abstract: </strong>Buckling of slender structures, such as perforated columns and cylindrical shells, underpins a wide range of systems and processes, from the structural failure of rocket fuselages and grain silos to engineered devices such as shock absorbers and crumple zones. Historically, research has primarily focused on predicting the onset of buckling—that is, the loss of the original configuration under excessive loading—rather than on understanding how structures evolve in the post-buckling regime. Recently, however, the study of buckling has experienced a renaissance, with post-buckling mechanical responses increasingly exploited to achieve new functionalities, for example enhancing fracture resistance in stretchable electronics and flexible displays.<br>\r\n<br>\r\nWhile most existing studies consider elastically deforming systems whose behaviour arises primarily from geometric nonlinearities, this talk presents examples in which geometric effects are coupled with nonlinear constitutive responses, giving rise to new post-buckling mechanisms. First, we investigate the buckling of hard, perforated (“holey”) structures that exhibit auxetic behaviour but, unlike their purely elastic counterparts, undergo post-buckling softening. The resulting negative stiffness is captured using a pseudo-plastic constitutive model that describes nonlinearities emerging from the structural microarchitecture.<br>\r\n<br>\r\nWe then apply a similar framework to examine the buckling of beverage cans largely filled with liquid under axial compression. Whereas empty cylindrical shells typically develop periodic buckling patterns that break both axial and circumferential symmetry, liquid-filled cylinders buckle axisymmetrically. The resulting ring-shaped buckles are localized and emerge sequentially, progressively covering the can surface. We show that this behaviour arises from nonlinear, spatially anisotropic hoop stresses that soften and subsequently re-stiffen during compression.<br>\r\n<br>\r\n<strong>Biography: </strong>Draga Pihler-Puzovic is a Reader in the Department of Physics and Astronomy at the University of Manchester and a core member of the Manchester Centre for Nonlinear Dynamics.
