Semantic Machines / Lectures in brief
Short narrated videos of recent lectures on AI, built by AI agents from the recordings.
These are short narrated summaries of recent lectures and talks on AI by Dominik Lukeš. Each video runs four to eight minutes and follows one lecture from start to finish, for people who missed it or want the argument without the hour. Where the slides are published, each summary links to the full slides.
The summaries are AI-assisted. Agents wrote each script from the recording and the slides, drew the pictures and rendered the video, and the narrator is a synthetic voice. Dominik reviewed them, but they are summaries, not recordings of him. The site is also an example of what can be made from a recorded lecture.
