Committee machine

If the two classes are not linearly separable yet do not overlap, correct classification may be achieved by what is called a committee machine . Here a group of mutually independent decision vectors decides on the classification, the final result being given by a majority vote (Fig. lb). If the two classes overlap, no reliable decision is possible (Fig. Ic).

In consequence of the randomness of the trained weight vector a classification by a committee machine (Chapter 2.6.2.) or a dead zone training is advisable C117, 123, 159, 2953. 

A "committee machine uses several different classifiers for the same classification problem in a parallel manner. The classifiers may stem e.g. from different training processes with the same training set. The results (scalar products) are summarized to give the final classification. Threshold logical units are usually applied and the majority of votes determines the class membership. Correct classification for all members of the training set may be obtained by a committee machine even if the data set is not Linearly separable. Unfortunately, no exhaustive theory about the training of several parallel classifiers exists. 

A committee machine is a special case of a "layered machine . 

Until a few years ago, there was no widely accepted standard for a voltage endurance test of the rotating machines. Different agencies had adopted different practices on different assumptions, pending a final decision by the lEC working committee TC-2 of lEC 60034-15. The committee submitted its report in 1988 and the following test data, which are now universally adopted, are based on this report.

The resistance method gives an average temperature of the whole winding. Some parts will be hotter than others usually the end turns will be somewhat cooler than parts of the winding in the middle of the iron core. NEMA committee members have been collecting test data on many machines to determine the correlation between temperature measurements by detector and by resistance, and the standards are periodically updated to reflect any of the technology improvements. 

When rotation occurs, static imbalance translates into a centrifugal force. As a result, this type of imbalance is sometimes referred to as force imbalance and some balancing machine manufacturers use the word force instead of static on their machines. However, when the term force imbalance was just starting to be accepted as the proper term, an American standardization committee on balancing terminology standardized the term static instead of force. The rationale was that the role of the standardization committee was not to determine and/or correct right or wrong practices, but to standardize those currently in use by industry. As a result, the term static imbalance is now widely accepted as the international standard and, therefore, is the term used in this chapter.

Unfortunately, Muller had not been nominated for the prize that year, so he could not receive one. Only Lauger had been nominated. The prize committee must have sat back and waited for Muller to be nominated the following year, but in 1947, no one at all—especially no one from Basel s divided scientific community—nominated him. Finally, in 1948, Muller s supporters reached farther afield to find a nominator. In the end, five medical school professors from Istanbul, Turkey, nominated Muller for the prize in medicine or physiology. None of these behind-the-scenes machinations was publicly known, of course. Records of the Nobel Prize deliberations were sealed until the late 1990s. 

With the exception of the PMD machines and the SCWO system, all of the components in the unit operations of the GATS process are commercially available. In its assessment of the General Atomics EDP for a GATS facility at Blue Grass, the committee addressed the following issues ... 

Physical testing of rubbers is the concern of PRI/22 which has a panel to deal with electrical tests. Until recently, there were 4 other active panels to split the detailed work on test methods but, as a result of the drive to economise effort and the effects of virtually all test methods coming from ISO, they were disbanded. Other committees which should be mentioned in the context of testing are PRI/71 which deals with flexible cellular materials, PRI/20 for accuracy of test machines, PRI 26 for burning behaviour of plastics and rubber and PRI/23 for chemical testing. Unfortunately, systems are never as simple as we would like specialised tests may be considered in product committees and not all products containing rubber are covered in PRI committees... 

Scientists at the National Laboratories of the National Committee for Nuclear Energy (C.N.E.N.) at Frascati, Italy pioneered the first electron-positron ring in 1959. Each beam of the machine was 0.25 GeV and yielded a center-of-mass energy of 0.5 GeV. This ring was lata moved to the Orsay laboratory outside Paris, France. The number of such rings grew quite rapidly.
