maximized. If there exists no hyperplane that can split the "yes" and "no" examples, an SVM will choose a hyperplane that splits the examples as cleanly as possible, while still maximizing the distance to the nearest cleanly split examples. The parameters of the maximum-margin hyperplane are derived by solving a quadratic programming (QP) optimization problem. There exists several specialized algorithms for quickly solving the QP problem that arises from SVMs. The original SVM was a linear classifier. However, Vapnik suggested using the kernel trick (originally proposed by Aizerman). In the kernel trick, every time a linear algorithm uses a dot product, replace it with a non-linear kernel function. This causes the linear algorithm to operate in a different space. For SVMs, using the kernel trick makes the maximum margin hyperplane be

Abstract machine

a computer. Different branches of computer science/engineering put somewhat differing specialized meanings into this notion, as seen below. Abstraction means a processor design which is not intended to be implemented as hardware, but which is the notional executor of a particular intermediate language (abstract machine language) used in a compiler or interpreter. An abstract machine has an instruction set, a register set and a model of memory. It may provide instructions which are closer to the language being compiled than any physical computer or it may be used to make the language implementation easier to port to other platforms. A virtual machine is an abstract machine for which an interpreter exists. Examples: ABC programming language, Abstract Machine Notation, ALF, CAML, F-code, FP/M, Hermes, LOWL, Christmas, SDL, S-K reduction machine, SECD, Tbl,

numbers specified for drums. The General MIDI specification reserves MIDI channel 10 for this purpose. They are specialized for the creation of rhythms by playing synthesized or sampled drum sounds in a predetermined order. The original drum machines were referred to as rhythm machines because they only played preprogrammed rhythms such as mambo, tango, etc. About 1980 user-programmable drum machines appeared, allowing musicians to create any rhythm they wanted. The Roland TR-808 was one of the first and most popular of the programmable drum machines and the sounds that are particular to that machine have become pop music clichés, heard on countless recordings. Early examples such as the TR-series used a method of synchronization called DIN-synch, or synch-24. Some of these machines also output analog voltages CV/Gate that could be used

Chinese input methods for computer
at 2008-05-12 10:12:06
to select a character from a menu generally have sophisticated methods for guessing which characters the user intends based on context. Different people are most comfortably with different methods and each standard has its strengths and weaknesses. For example, for someone who is already familiar with pinyin, the pinyin method can be learned most quickly. However, the maximum typing rate is limited, and learning the system is difficult for some who doesn't know pinyin. Wubi takes much effort to learn, but expert typists can enter text much faster than the phonetic methods. Because of these factors, there is no likelihood of a "standard" method evolving. Other means of inputting Chinese characters are not widely used but include stylus and tablet, with hand-writing recognition software, as the most common alternative, and then
