Collaborative filtering (CF) has been one of the most important and popular recommendation methods, which aims at predicting users’ preferences (ratings) based on their past behaviors. Recently, various types side information beyond explicit ratings users give to items, such as social connections among metadata have introduced into CF shown be useful for improving performance. However, previous...

forest classification on the basis of satellite images is a promising technique both for primary map production and for map updating and forest monitoring. for accurate for-est classification into three classes, using mapping by canopy cover density “high spatial resolution satellite images have to be used in order to obtain the required spatial detail” [schneider, 1999]. at the same time, the ...

The explosive growth of the World Wide Web, and the resulting information overload, has led to a miniexplosion in World Wide Web search engines. This mini-explosion, in turn, led to the development of ProFusion, a meta search engine. Educators, like other users, do not have the time to evaluate multiple search engines to knowledgeably select the best for their uses. Nor do they have the time to...

Humans interact with each other using different modalities of communication. These include speech, gestures, documents, etc. It is only natural that human computer interaction (HCI) should facilitate the same multimodal form of communication. In order to capture this information, one uses different types of sensors, i.e., microphones to capture the audio signal, cameras to capture life video im...

We motivate and offer a formal definition of validation as it applies to information fusion systems. Common definitions of validation compare the actual state of the world with that derived by the fusion process. This definition conflates properties of the fusion system with properties of systems that intervene between the world and the fusion system. We propose an alternative definition where ...

Subsequent revisions to the Joint-Directors of Lab (JDL) model emphasize the differentiation between fusion (estimation) and sensor management (control). Two diverging groups include one pressing for fusion automation (JDL revisions) and one advocating the role of the user (User-Fusion model). The center of debate is real-world delivery of fusion systems which requires presenting fusion results...

he transformation of the u.s. military from cold War to current operations includes a greater reliance on distributed systems and on sensor data fusion as a force multiplier. The highly mobile fighting force will depend on the distributed operation and fusion of data to achieve net sensor performance greater than could be practically achieved by any single sensor. Detection systems information ...
