I used to teach AI & ML for media, art & design: PerttuHamalainen/MediaAI: Aalto University's Intelligent Computational Media course (AI & ML for media, art & design)

However, I killed the course as one can increasingly get better results with commercial tools than tweaking and finetuning models oneself. Instead, I’m now focusing more on teaching advanced game programming and technical art, with some AI & ML material sprinkled in.

Meanwhile, I’ll keep posting significant new papers etc. here.

Note that this section is very much under construction, waiting for me to clean up and migrate stuff from my private iCloud notes.
