Foojay Podcast published in July 2024

In this Foojay podcast, we enter the world of mathematics by discussing Vectors and how they are crucial for AI and machine learning. As ChatGPT explains: "A Vector is a mathematical structure that holds numerical values. Vectors are fundamental to the field of Artificial Intelligence, as they allow mathematical operations to be performed efficiently and form the basis of many machine learning algorithms." OK, but how are these vectors crucial for the whole Artificial Intelligence evolution?

This is the last podcast of season 3, we're taking a summer break and will be back in September with the release of Java 23 and many more OpenJDK-related topics!
