    The paper is so bad…

    the agent’s policy π … the environment ε

    What is up with AI papers using fancy symbols to notate abstract concepts when there isn’t a single other instance of the concept to be referred to

    They offer a bunch of tables with numbers in a metric that isn’t explained, showing that they are exactly the same for “random” and “agent” policy, in other words, inputs don’t actually matter! And they say they want to use these metrics for training future versions. Good luck.

    For the sample size they are using 60% seems like a statistically significant rate, and they only tested at most 3 seconds after real gameplay footage.

    Sidenote: Auto-regressive models for much shorter periods are really useful for when audio is cutting out. Those use really simple math, they aren’t burning any rainforests

    I’m willing to retract my statement that these guys don’t have any ulterior motives.

      The paper starts with a weirdly bad definition of “computer game” too. It almost makes me think that (gasp) the paper was written by non-gamers.

      Computer games are manually crafted software systems centered around the following game loop: (1) gather user inputs, (2) update the game state, and (3) render it to screen pixels. This game loop, running at high frame rates, creates the illusion of an interactive virtual world for the player.

      No rendering: Myst

      No frame rate: Zork

      No pixels: Asteroids

      No virtual world: Wordle

      No screen: Soundvoyager, Audio Defense (well these examples have a vestigial screen, but they supposedly don’t really need it)
