PBIL
In computer science and machine learning, population-based incremental learning (PBIL) is an optimization algorithm, and an estimation of distribution algorithm. This is a type of genetic algorithm where the genotype of an entire population (probability vector) is evolved rather than individual members. The algorithm is proposed by Shumeet Baluja in 1994. The algorithm is simpler than a standard genetic algorithm, and in many cases leads to better results than a standard genetic algorithm. Algorithm In PBIL, genes are represented as real values in the range ,1 indicating the probability that any particular allele appears in that gene. The PBIL algorithm is as follows: # A population is generated from the probability vector. # The fitness of each member is evaluated and ranked. # Update population genotype (probability vector) based on fittest individual. # Mutate. # Repeat steps 1–4 Source code This is a part of source code implemented in Java. In the paper, learnRate = 0. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...

Sumitomo
The is one of the largest Japanese ''keiretsu'', or business groups, founded by Masatomo Sumitomo (1585-1652) around 1615 during the early Edo period. History The Sumitomo Group traces its roots to a bookshop in Kyoto founded circa 1615 by Masatomo Sumitomo, a former Buddhist monk. Even today management of the group is guided by his "Founder's Precepts", written in the 17th century. Copper refining made the company famous. Riemon Soga, Masatomo Sumitomo's brother-in-law, learned Western methods of copper refining. In 1590 he established a smelting business, ''Izumiya'', literally meaning "spring shop". Riemon perfected techniques that allowed the extraction of silver from copper ore, something Japanese technology had not previously accomplished. The smelting and smithing business was moved from Kyoto to Osaka by the late 17th century. Soga passed control of the company to his son Tomomochi who managed its transformation into a major trading house during the Edo period. Sumitom ...
