KL Zero: KL divergence intuition game

Press start in the chart. The blue line is the generated distribution; draw the green line before the timer ends. KL divergence measures how surprising the blue distribution P would look if your green distribution Q were used instead. Draw any probability distribution that sums close to 1 and gets as close as possible to the target KL divergence number.

Should you normalize RGB values by 255 or 256?

https://30fps.net/pages/255-vs-256-division/std_vs_alt_numberline.png
The standard approach maps 0 to 0.0 and 255 to 1.0, while the alternative adds a 0.5 bias and divides by 256. The standard approach is a mid-riser quantizer with L=255, wasting bandwidth but suitable for image processing.

Age verification for social media, the beginning of the end for a free internet?

https://mullvad.net/press/MullvadVPN_logo_Round_RGB_Color_positive.png
Governments worldwide are introducing age verification measures to supposedly protect children, but this actually lays the groundwork for a fully government-controlled internet and mass surveillance. Identity verification, which is the correct term for age verification, restricts freedom of information and expression, and can be used to censor and control citizens, ultimately leading to a ...

The Frame Problem (2004)

The frame problem is a challenge in logic-based artificial intelligence to represent the effects of actions without explicitly representing non-effects. Philosophers have reinterpreted the problem as an epistemological issue of how to limit the scope of reasoning required to derive the consequences of an action.
