War Stories
The training has prepared me well to tackle my own project. It helped me to understand how to set up the project and which tools or algorithms I can use for it.
The content of the training is quite compact, but not overloaded, so that there was also time for individual questions.
I particularly liked the fact that Alessandro shared his experiences from older projects, which allowed him to point out potential problems.
