摘要:
A retrieval information that is a retrieval target, acquired from an information source, is arranged on a vector space. Data of a usage information and a content specifying manners of usage, used by the user in the past is acquired by a usage-information acquisition unit. A user's preference extraction unit extracts a preference of a user from the data, and notifies a number-of-effective-elements reduction unit of the extracted data. The number-of-effective-elements reduction unit evaluates each element of a vector of retrieval information by using the preference of the user, and reduces the number of effective elements by removing the elements smaller than a certain criteria. Thereafter, a statistic is acquired in the vector space of the vector of the retrieval information, and the cosine normalization is performed on the result that includes a large number of elements, and the normalization in which the variation of the statistic was compensated by the average weight is performed on the result that includes a small number of elements.

There is provided a failure determination system for a continuously variable transmission of a belt type, which is capable of determining failure of control valves for performing speed varying operation, and enhancing maintainability. An ECU controls a transmission ratio of the transmission to a fixation-determining LOW-side range when the vehicle is standing. When the transmission ratio during stoppage of the vehicle is within a stop-time OD-side range if engine torque≧OD-time DR-side reference torque and at the same time the transmission ratio

A position of an observer in a stereoscopic observing region is detected by a position detecting unit. A right-eye image and a left-eye image which are seen from the detecting position are formed by an image forming unit and displayed on a display. By setting an aperture position of a projection optical system, the right-eye image is projected to the right-eye position of the observer and the left-eye image is projected to the left-eye position, thereby allowing a stereoscopic image to be observed. Further, an aperture is set so as to project the right-eye image or left-eye image to a position different from the detecting position of the observer, thereby allowing a same image to be seen to both eyes of another observer and allowing a two-dimensional image to be observed.
