Artificial neural network calculating device and method for sparse connection

ActiveCN105512723ASolve the problem of insufficient computing performance and high front-end decoding overheadAdd supportMemory architecture accessing/allocationDigital data processing detailsActivation functionMemory bandwidth
An artificial neural network calculating device for sparse connection comprises a mapping unit used for converting input data into the storage mode that input nerve cells and weight values correspond one by one, a storage unit used for storing data and instructions, and an operation unit used for executing corresponding operation on the data according to the instructions. The operation unit mainly executes three steps of operation, wherein in the first step, the input nerve cells and weight value data are multiplied; in the second step, addition tree operation is executed, the weighted output nerve cells processed in the first step are added level by level through an addition tree, or the output nerve cells are added with offset to obtain offset-added output nerve cells; in the third step, activation function operation is executed, and the final output nerve cells are obtained. By means of the device, the problems that the operation performance of a CPU and a GPU is insufficient, and the expenditure of front end coding is large are solved, support to a multi-layer artificial neural network operation algorithm is effectively improved, and the problem that memory bandwidth becomes a bottleneck of multi-layer artificial neural network operation and the performance of a training algorithm of the multi-layer artificial neural network operation is solved.

Short text classification method based on convolution neutral network

The invention discloses a short text classification method based on a convolution neutral network. The convolution neutral network comprises a first layer, a second layer, a third layer, a fourth layer and a fifth layer. On the first layer, multi-scale candidate semantic units in a short text are obtained; on the second layer, Euclidean distances between each candidate semantic unit and all word representation vectors in a vector space are calculated, nearest-neighbor word representations are found, and all the nearest-neighbor word representations meeting a preset Euclidean distance threshold value are selected to construct a semantic expanding matrix; on the third layer, multiple kernel matrixes of different widths and different weight values are used for performing two-dimensional convolution calculation on a mapping matrix and the semantic expanding matrix of the short text, extracting local convolution features and generating a multi-layer local convolution feature matrix; on the fourth layer, down-sampling is performed on the multi-layer local convolution feature matrix to obtain a multi-layer global feature matrix, nonlinear tangent conversion is performed on the global feature matrix, and then the converted global feature matrix is converted into a fixed-length semantic feature vector; on the fifth layer, a classifier is endowed with the semantic feature vector to predict the category of the short text.

System and method for creating pathfiles for use to predict patterns of web surfaces

A prefetching and control system for a computer network environment. The user configures the client's prefetch parameters which are: enabling / disabling prefetching, prefetch threshold value, and the maximum number of documents to prefetch. A prefetch value or weight is contained in the Hypertext Markup Language (HTML) page or prefetch file, called a pathfile, for each link. The HTML page contains the prefetch values for each of its links, while pathfile contains the weights for every link on the HTML page associated with the Universal Resource Locator (URL). The client compares the prefetch or weight values of each link with its threshold value to decide if the link should be prefetched and placed in the local cache as long as the maximum number of documents to prefetch is not exceeded. Pathfiles reside on the server and are created by the server or web administrator / author. The server automatically creates the pathfiles from its log files which are filtered to retain all of the valid document requests and average paths are derived from the filtered results. Weights are assigned to each path in the URL by the server and inserted into the pathfile along with the associated paths. If no log files exist on the server, then the web administrator / author may manually enter in the weights for each path.

Method for automatic correction and tiled display of plug-and-play large screen projections

The invention discloses a method for automatic correction and tiled display of plug-and-play large screen projections. The method comprises the steps as follows: adaptively generating a checker pattern with a certain resolution ratio, projecting by projectors in sequence, capturing by cameras, carrying out feature detection and identification on complicated projection surfaces or checkers under the illumination condition with a multi-feature detection method based on color and geometry, and creating a Bezier curve function to represent a corresponding relation of points between projector images and camera images; and obtaining effective display areas for screen projection with a quick approach method, determining a corresponding relation of the projection contents of the projectors and the display areas, carrying out geometrical distortion on the images to be projected for geometrical correction, and calculating weight values of pixels in projection overlapping areas with a distance-based nonlinear weight value distribution method for fusion of edge brightness. According to the invention, a plurality of projection images of irregular surfaces can be aligned and seamlessly spliced, and the whole method is simple and easy to use, higher in autonomy and better in seamless splicing performance.
