45 results about "Viewdata" patented technology

Viewdata is a Videotex implementation. It is a type of information retrieval service in which a subscriber can access a remote database via a common carrier channel, request data and receive requested data on a video display over a separate channel. Samuel Fedida, who had the idea for Viewdata in 1968, was credited as inventor of the system. The first prototype became operational in 1974. The access, request and reception are usually via common carrier broadcast channels. This is in contrast with teletext.

Large-scale multi-view data self-dimension-reduction K-means algorithm and system

The invention relates to a large-scale multi-view data self-dimension-reduction K-means algorithm and a system, and belongs to the technical field of information processing, and the method comprises the steps: 1, carrying out the normalization of data with different features, and enabling all data to be in a range of [-1, 1]; 2, initializing; 3, optimizing the algorithm; and 4, using a data set tooptimize the algorithm according to the algorithm until the algorithm is finally converged to obtain a final clustering result, measuring the clustering effect by using the interaction information entropy and the purity, and repeating the step 3 by selecting different initial values, and removing the average value of the result to complete the experiment. The relationship between the features andthe clustering targets is fully considered; information complementation among different views is utilized, self-dimension reduction of high-dimensional data is achieved by searching for an optimal subspace on a single view, a loss function is reconstructed through non-negative matrix factorization (NMF), the different views share the same clustering indication matrix, therefore, multi-view information complementation is achieved, and clustering of large-scale multi-view data is completed.

Multi-view clustering method based on multi-manifold dual graph regularized non-negative matrix factorization

The invention provides a multi-view clustering method based on multi-manifold dual graph regularized non-negative matrix factorization. The multi-view clustering method comprises the following steps of: S10, acquiring views to be clustered; S20, constructing an adjacency matrix of a data graph and an adjacency matrix of a feature graph for each view to be clustered; S30, acquiring a target function of multi-manifold dual graph regularized non-negative matrix factorization through a consistency coefficient and multi-view local embedding; S40, conducting iterating a preset number of times by using an iterative weighting method according to the target function, and updating the adjacency matrix of the data graph of each view to be clustered, the adjacency matrix of the feature graph of each view to be clustered and graph regular terms to obtain a feature matrix of each view to be clustered; and S50, analyzing the feature matrix of each view to be clustered by using a k-means clustering algorithm to realize multi-view clustering. Compared with a traditional multi-view clustering method, the clustering method has the advantages that structural information and features contained in viewdata are more effectively utilized, clustering effect is greatly improved, and better clustering performance is brought.
