Rice winnowing, Uttarakhand, India Winnowing in a village in Tamil Nadu, India Use of winnowing forks by ancient Egyptian agriculturalists. Winnowing is a process by which chaff is separated from grain. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation. In its simplest form, it ...
The winnow algorithm [1] is a technique from machine learning for learning a linear classifier from labeled examples. It is very similar to the perceptron algorithm.However, the perceptron algorithm uses an additive weight-update scheme, while Winnow uses a multiplicative scheme that allows it to perform much better when many dimensions are irrelevant (hence its name winnow).
In sedimentology, winnowing is the natural removal of fine material from a coarser sediment by wind or flowing water. Once a sediment has been deposited, subsequent changes in the speed or direction of wind or water flowing over it can agitate the grains in the sediment and allow the preferential removal of the finer grains.
Chaffing and winnowing is a cryptographic technique to achieve confidentiality without using encryption when sending data over an insecure channel. The name is derived from agriculture: after grain has been harvested and threshed , it remains mixed together with inedible fibrous chaff .
A winnowing barn consists of a large shed on tall posts with a hole in the floor. Raw, husked rice was carried up into the barn by slaves and then the grain was dropped through the hole. As the grain dropped to the ground, the lighter and undesirable chaff was carried away in the wind, leaving a mound of purified rice grains directly below the ...
