Workshop Artificial Intelligence

BG Klosterneuburg 25.3.2025

Technical Fundamentals

The workshop did not cover the foundational aspects in detail because the theme was "AI for All" and the goal was to teach skills for the efficient use of AI in everyday life and school.

However, those interested in this topic were referred to a separate workshop that can be completed independently:

Teachable Machine

The Teachable Machine served as a very vivid, practical example of the capabilities of deep learning that the students could carry out themselves:

Clustering

Clustering was presented as a practical example of unsupervised learning. Students entered the distance from their home to school and the number of years since their last move into a list.
This practical example explained how clusters are created. To do this, you repeatedly pairwise connect the nearest points and stop when enough clusters have been created..

Prompting

Text recognition on graphics was successfully tested in practice.

A prompt was created from an image, and the prompt was then converted back into an image. The comparison between the result and the original was very interesting.

Decision Trees

Since there was still some time left, after a short explanation, students created a decision tree from input data. This process is usually implemented automatically using a program. Orange Data Mining, for example, can automatically generate decision trees from tables.
Manually carrying out an actual AI procedure gives participants the experience of stepping into the role of artificial intelligence themselves.

The example used was a table that used weather data to determine whether the day was suitable for cycling.

Why can such a system be called intelligent?

The OCG would like to thank you for the opportunity to hold the workshop as part of the "All DIGITAL Weeks" and looks forward to future collaborations.
