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).
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 ...
However, the compiler automatically transforms the code so that the list will "silently" receive objects, while the source code only mentions primitive values. For example, the programmer can now write list. add (3) and think as if the int 3 were added to the list; but, the compiler will have actually transformed the line into list. add (new ...
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 .
Key to the benefits of Intentional Programming is that domain code which capture the intentions are not stored in source code text files, but in a tree-based storage (could be binary or XML). Tight integration of the environment with the storage format brings some of the nicer features of database normalization to source code .
Rather than a procedural paradigm, where one program has a loop that is activated only one time, the declarative paradigm used by Jess applies a set of rules to a set of facts continuously by a process named pattern matching. Rules can modify the set of facts, or can execute any Java code. It uses the Rete algorithm [1] to execute rules.
Otherwise, the bootstrap compiler is to be written in one of the programming languages which does exist on the target machine, and that compiler will generate something which can execute on the target, including a high-level programming language, an assembly language, an object file, or even machine code.
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.
