Day 4 was spent learning on Reutlingen University campus. We connected with the students there, after which we completed workshops in three different subjects:Artificial Intelligence, blockchain, and programming in Cobot language.I personally enjoyed the Artificial Intelligence portion. I have previously worked on a project and had an internship using A.I. so I found it to be a great second edition in learning about Machine Learning, Image Processing, and Object Recognition. The workshop expanded my knowledge and allowed me to take what I learned on the internship a step further.
