Alpha left Mug
The "alpha left in X" refers to the amount of opportunity lies in optimizing across a particular dimension "X". This is a homage to the learning rate in stochastic gradient descent (referred as "Alpha"). If there's a lot of alpha left in a dimension, you more quickly approach the local minima (minimizing loss with larger leaps). Therein lies opportunity through the asymmetry of effort to gain (eg. getting twitter clout or scamming VCs out of money). Once the local minima is reached, large alphas will increase loss, at which point the asymmetry of effort to gain is lost. For more; see some adaptive gradient descent algorithms e.g. AdaGrad.

Customer Reviews

as a fan of non-Z-generation-UD (since 2000 more or less) , especially of old-school definitions ("phat!") (as Nick, the more time passes by, the more I reach my inner age = 75 XD) , I totally appreciated the delivery in time for Christmas! (whispering) Perhaps printing quality in the Spain printing company is not as good as in the US, but - hey! - I got it before Christmas as a gift for my thank-God-non-Gen-Z-sister! ;) hugs from the eighties, and from Italy, and thanks!

Like the mug for my daughter, but didn’t notice that I had color choices when checking out. The yellow was pre-set so I got that color. Would much rather have selected a different color.
Cute, well-made mug! Exactly like the photo. I can't wait to give this as a gift this Christmas!
The description of a person by their names is the realest I’ve ever come across
Mug looks great and everything is spelled correctly.
