PickVidsBest Information theory & signal processing Videos
The 43 Information theory & signal processing videos here were recommended by different people across different months. Choose by who it is for: 11 introductory, 12 intermediate, 17 for a general viewer, and 3 for someone who wants the harder derivation. Most of them are an explainer. What they share is that one picture or analogy is used to supply a missing concept. Channels you will keep seeing include 3Blue1Brown, Computerphile, Veritasium.
Solving Wordle using information theory
3Blue1Brown uses Wordle as an excuse to teach information theory and entropy, building a solver that picks guesses by expected information and incorporating word frequencies.
Hold music used to sound better. Here's why.
Tom Scott explains why hold music sounds worse than it used to, tracing it to old telephone exchanges and the audio compression applied by modern switches.
Samplerates: The Higher the Better, Right?
Dan Worrall explains when higher sample rates help in recording and mixing, and when they do not.
Succinct Data Structures
Edward Kmett's 2013 talk at Prezi in Budapest on succinct data structures, which store data in close to the information-theoretic minimum space while supporting fast queries.
Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI | Lex Fridman Podcast #75
Lex Fridman interviews Marcus Hutter of DeepMind about universal artificial intelligence, AIXI, Kolmogorov complexity, Solomonoff induction and the idea of intelligence as compression.
The Visual Microphone: Passive Recovery of Sound from Video
