BLACK BOX. -- "The neural network actually beats the level instead of pausing the game."" "-- "Yes but neural network heuristics are black magic that I will never understand." " "-- "Funny you say that, because the values of the nodes are generally considers to be a black box. Humans cannot understand the reason behind the node values. Just that (for a well-trained network) they work." https://www.reddit.com/r/todayilearned/comments/3d3vct View in LinkedIn

CODER BACKCHAT. -- "The evolution mechanism decided that the best way to win was to not play/fight. Evolution. Nice."" "-- "A strange game. The only winning move is to not play.""

MACHINE SMARTS. "Someone programmed a software that could play super mario [edit:] Tetris, and the goal was to stay alive as long as possible. sometime along the road the program figured out that pressing pause had the best results and stuck with it. goddamn thing figured out best way to win the game was not to play it." https://www.reddit.com/r/todayilearned/comments/3d3vct View in LinkedIn

AI TEMPER TANTRUM. "Oh man. We've done it. We've finally forced an AI to ragequit." https://www.reddit.com/r/todayilearned/comments/3d3vct View in LinkedIn

GENETIC PROGRAMMING. "My 'ant colony' produced ants that got progressively better at finishing the first 80% of the maze, but the maze got more difficult towards the end, and as things got more difficult, they got stuck - so they would get faster and faster at getting 80% of the way there and then, unable to figure out the next bit, just hide to maximize the 'points' my system would grant them, and their chances of survival - how awesome is that! - my own (extremely basic) computer system outsmarted me." https://www.reddit.com/r/todayilearned/comments/3d3vct View in LinkedIn

EXAPTATION "is a term used in evolutionary biology to describe a trait that has been co-opted for a use other than the one for which natural selection has built it." Darwin first conceived of the idea. http://www.livescience.com/39688-exaptation.html View in LinkedIn

BACKDOOR. "Unused gates still present parasitic loading. It can affect timing and therefore the output waveforms." https://www.reddit.com/r/todayilearned/comments/3d3vct View in LinkedIn

"EVOLVING COMPUTER CHIPS is a huge part of creating a good AI. There are already several companies working with this technology. When it was first worked up it created such efficient chips that they couldn't be replicated, as they made use of microscopic differences and scratches on the chip itself." The adaptive genetic toolkit of exaptation. Nice. https://lnkd.in/evQuB2z View in LinkedIn

SO ENDS this first weekend on the theme of perfection in nature. Humans want to see order in the universe, stability, and perfection. Some of the recent ideas that humanity has encountered are those of chaos, instability and change, and imperfection. These ideas are unsettling to many, and to the collective consciousness that has been fed an ordered hierarchical world. And the quantum world in particular has put the fox in with the pigeons.

MUTANT KILLS. "Mutation testing (or Mutation analysis or Program mutation) is used to design new software tests and evaluate the quality of existing software tests. Mutation testing involves modifying a program in small ways. Each mutated version is called a mutant and tests detect and reject mutants by causing the behavior of the original version to differ from the mutant. This is called killing the mutant. Test suites are measured by the percentage of mutants that they kill. New tests can be designed to kill additional mutants." https://en.m.wikipedia.org/wiki/Mutation_testing View in LinkedIn
