SELECTION OF THE PERFECT. "On the other hand, very many enzymes appear not to be involved in metabolic control...and for these we can ask to what extent the selective pressures of evolution have produced the perfect catalyst....In this Account we shall suggest one measure of perfection." http://pubs.acs.org/doi/abs/10.1021/ar50112a001 View in LinkedIn

CONFLICTED PERFECTION. "For some enzymes, there is going to be a conflict between changes that maximize catalytic effectiveness and changes that optimize control, and for these enzymes we may expect that some catalytic power has been sacrificed to the higher good of metabolic control." http://pubs.acs.org/doi/abs/10.1021/ar50112a001 View in LinkedIn

"NEURAL NETWORKS are called black boxes because the training algorithm finds the optimal node values to solve a problem, but looking at the solution it is impossible to tell why that solution works without decomposing every element of the network. In other words, the node values are extremely sensitive to the context (nodes they connect to), so you have to map out the entire thing to understand it." https://www.reddit.com/r/todayilearned/comments/3d3vct View in LinkedIn

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

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
