Assignee:

Microsoft Corporation - Redmond WA

International Classification:

Abstract:

A generalization of frequent item sets to error-tolerant frequent item sets (ETF) is disclosed, together with its application in data clustering using error-tolerant frequent item sets to either build clusters or as an initialization technique for standard clustering algorithms. Efficient feasible computational algorithms for computing ETFs from very large databases is presented. In one embodiment, a method determines a plurality of weak ETFs, which are strongly tolerant of errors, and determines a plurality of strong ETFs therefrom, which are less tolerant of errors. The resulting clusters can be used as an initial model for a standard clustering approach, or may themselves be used as the end clusters. In one embodiment, the data covered by the strong clusters is removed from the data, and the process is repeated, until no more weak clusters can be found. Te invention includes methods for constructing ETFs from more general data types: data sets that include categorical discrete, continuous, and binary attributes.

US Classification:

707724, 707706

Abstract:

Image galleries are automatically located within documents, such as web pages. Documents that are determined to contain image galleries may be treated differently when storing the document for later retrieval by an image search engine. In one implementation, the image galleries are automatically located within a document by calculating position information indicating relative positions of images in the document. The document may be determined to contain an image gallery when the position information indicates that the images in the document are generally evenly distributed.

Abstract:

Systems and methods are described for providing co-presence in an augmented reality environment. The method may include controlling a first and second computing device to detect at least one plane associated with a scene of the augmented reality environment generated for a physical space, receiving, from the first computing device, a first selection of a first location within the scene and a first selection of a second location within the scene, generating a first reference marker corresponding to the first location and generating a second reference marker corresponding to the second location, receiving, from a second computing device, a second selection of the first location within the scene and a second selection of the second location within the scene, generating a reference frame and providing the reference frame to the first computing device and to the second computing device to establish co-presence in the augmented reality environment.
