Gains in machine-learning algorithms can come from fundamental changes in their architecture, loss function, or optimization strategy—how they use feedback to improve.

From Science Magazine

The loss function controlling the learning was considering only the error of the next step, not the validity of the solution over many steps, which is what we really want.

From Nature

Machine-learning algorithms require researchers to specify a ‘loss function’, which determines the severity of various errors — such as whether it is better to make two errors of 1% each, or a single error of 2%.

From Nature

"You can have visual signals for safety and other ways to make the workplace safer and not make everything rely on hearing and you can also find special types of hearing protection or other assistive devices that help a person who has hearing loss function well in a noisy situation," Rabinowitz said.

From Reuters

We may therefore tentatively assume that the fever which marks the onset and frequently the course of these benign stupors is the result of a failure of the heat loss function, this being due to an imbalance in the involuntary nervous system that is occasioned, in turn, by insufficient circulating adrenalin, and the final cause for the poor suprarenal function is to be traced to the most consistent symptom of the stupor, namely, apathy.
