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.

Webinar recording: Learn to record and transcribe securely with the Dictaphone app

In this webinar recording, you will watch a hands-on workshop introducing Dictaphone – a UCloud application that enables researchers to securely record and transcribe interviews directly from their own devices, even when working with sensitive data. 

In the recording, we guide you through how to: 

  • Record interviews and conversations using Dictaphone on your laptop or smartphone 
    Audio is streamed in real time to the secure UCloud backend, ensuring that no data is stored locally on your device – making Dictaphone well suited for handling sensitive data. 
  • Automatically transcribe recordings within the same workflow
    Dictaphone includes built-in transcription functionality, allowing you to convert speech to text quickly and efficiently. 
  • Make the most of Dictaphone, including tips, additional features, and real research use cases. 

This recording is relevant for researchers across all departments as well as students. 

Dictaphone is a beginner-friendly application and does not require any technical background.
