It would be impossible to learn properties and behavior of even a fraction of this number if it had to be done on the basis of individual compounds1. Fortunately, most chemical compounds can be grouped together in a few classes. Then, if we can properly classify a compound .we are at on...
Creating such a hierarchy allows for the explicit representation of domain knowledge, which corresponds to the content of textbook chemistry and at the same time can be interlinked with research reports in the literature as well as large-scale databases of chemical compounds. Targeted development of ...
The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (MAK Commission) introduced an extended classification scheme in 1998. In addition to the traditional three categories still used to date, now called: Category 1 (human carcinogen); Category 2 (ani...

database, consisting of 1738 small-molecules. The chemical compounds of the screening database with a predictive probability of ≥ 0.80 for increasing the lifespan ofCaenorhabditis eleganswere broadly separated into (1) flavonoids, (2) fatty acids and conjugates, and (3) organooxygen compounds...
(DWPI) to facilitate the manual classification of chemical compounds reported in patents. The system consists of 2200 numerical codes corresponding to a set of pre-defined, chemically significant structure fragments. The system is still used by Derwent indexers who manually assign patented chemicals ...
(Xiong et al.2015). With the aim of creating new varieties, breeders have developed novel methods to introduce heritable mutations into plant genomes. In the recent past, various mutagens like chemical compounds and irradiation were used to generate large pools of genetic variation in traditional ...

This problem was solved by careful determination of neural network learning parameters and forward sequential selection of input features. Finally, the fundamental limit of any classifier on this data was determined using Bayes error bounding.关键词: Chemical compounds Neural networks ...
