Workshop 26/2: CVAT – AI-Assisted Labeling

Date: February 26, 2026

Time: 13:15 to 14:30 CET

Location: Online via Zoom

CVAT, Computer Vision Annotation Tool, is an interactive video and image annotation tool, designed to facilitate the annotation of video and image data and accelerate the creation of high-quality datasets for computer vision tasks. CVAT is available on the UCloud platform, in the Application Store.

The webinar will show how to use CVAT on UCloud to:

Label and annotate data with the help of AI and OpenCV tools, including:

  • Use of cvat-cli
  • Run built-in model for detection and auto-annotation
  • Use of GPUS with built in models for faster annotation
  • Adding custom models (e.g. YOLO)

Efficiently manage large visual datasets with MinIO:

  • Allow CVAT to directly pull images from your UCloud MinIO buckets for annotation and export annotated data back, reducing manual imports/exports and ensuring data availability.

Using UCloud allows users to create fully reproducible and secure workflows that leverage high performance computing resources. Those features are often necessary for large dataset and accurate computer vision tasks.

Target audience: Researchers across all Departments, particularly who require high-precision data labeling, AI interested.

Technical Level: Basic to Intermediate

Workshop 19/2: Text classification using large language models

Date: 19 February 2026
Time: 13:15 – 14:30 (CET)
Location: Online, via Zoom

The purpose of this webinar is to demonstrate how to perform automated text classification using pre-trained, open-source large language models (LLMs). The efficiency that LLMs bring to otherwise laboursome workflows, such as text classification, makes it possible to work with much larger text corpora across all fields of research. The use case will focus on classifying text according to sentiment, but the general workflow is applicable to many other text classification tasks.

In the webinar, we will create a complete workflow which will consist of the following parts:

  1. Retrieving text data from online sources
  2. Storing and preparing the data for analysis
  3. Setting up the LLM text classifier
  4. Performing the text classification
  5. Displaying the results (for validation etc.)

The workflow will be set up on the UCloud platform. Using UCloud allows users to create fully reproducible and secure workflows that leverage high performance computing resources which are often necessary to run LLMs locally.

Workshop 11/6: UCloud Courses hands-on

Developing your own UCloud course app using a newly developed template-based approach

Join us for a hands-on workshop where we guide you through all the steps of developing a UCloud course app using our newly developed template-based approach. The concept involves having a dedicated app on UCloud for your university course that students can use in e.g., exercise/lab session and/or at home. An introduction to the approach can be found in this webinar recording.

In this workshop, you’ll learn how to:

  • Translate your course structure to a structure that is compatible with a UCloud course app.
  • Set up the course development environment which involves cloning the GitHub repository and running a course setup script.
  • Customize the provided templates to build a UCloud course app that includes all required components – software dependencies, scripts, datasets, and more.
  • Test the course on your computer during development to ensure everything functions correctly. We will also see how the final course app looks once it has been put on UCloud.

Git/GitHub and Docker are essential tools in the UCloud course development process. In the workshop, we will give short introductions to both tools primarily aimed at those participants who do not have experience with them. Participants can benefit from following introductory tutorials to Git and Docker in advance, although this is not a requirement.

Date: 11 June 2025

Time: 12:30-14:30 (CET)

Location: Online, via Zoom (link TBA)

Target audience: Researchers and teachers across all departments at all the Danish universities

Technical Level: Basic to Advanced
