摘要： A linear voltage-to-current converter (LVCC) circuit includes two transistors, one P-channel and one N-channel. The input voltage is applied to the gates of both transistors. The drains of the two transistors are connected. The source of the p-type transistor is connected to a first voltage rail, and the source of the N-channel is connected to a second voltage rail of lower voltage. The output is the difference between the current through the P-channel transistor and the N-channel transistor. A linear current-to-voltage converter (LCVC) circuit is similar to the LVCC circuit, except that the gates of the transistors are tied to the drains of the transistors. The input current is supplied to the drains, and the output voltage is the voltage of the drains.

摘要： A synaptic array according to the present invention comprises a plurality of electrically-adaptable elements. Electrons may be placed onto and removed from a floating node in each electrically adaptable element associated with at least one MOS insulated gate field effect transistor, usually the gate of the transistor, in an analog manner, by application of first and second electrical control signals generated in response to an adapt signal. The inputs to all synaptic elements in a row are connected to a common row input line. Adapt inputs to all synaptic elements in a column are connected together to a common column adapt line. The current supplied to all amplifiers in a column is commonly provided by a sense line. In order to adapt the synaptic elements in the M row by N column matrix of the present invention, the voltages to which a given column n of the matrix is to be adapted are placed onto the input voltage lines, and the synaptic elements in column n are then simultaneously adapted by assertion of an adapt signal on the adapt line for column n. The vectors of input voltages for adapting successive columns may be placed sequentially onto the row input voltage lines and used to adapt the columns of synaptic elements by assertion of the adapt signals on the appropriate column adapt lines until the entire array is electrically adapted. After each synaptic element has been adapted, the current flowing through it will be maximized when the voltage at the input of the synaptic element equals the voltage to which the synaptic element has been adapted. An electrically adaptable winner-take-all circuit has its inputs connected to the column-sense lines of the array.

摘要： A weight-storage and weight-adjustment circuit includes a first hot electron injection device coupled to a first floating gate and a second hot electron injection device coupled to the second floating gate. The floating gates are associated with two series connected MOS transistors. The first and second hot electron injection devices comprise gated lateral bipolar transistors. The weight may be decreased by injecting hot electrons from the first hot electron injection device onto the first floating gate to decrease the first analog voltage and increased by injecting electrons from the second hot electron injection device onto the second floating gate to decrease the second analog voltage. Circuitry are provided to periodically adjust the absolute voltage levels on the first and second floating gates to prevent them from becoming too negative over time. First and second electron tunneling devices are coupled to the first and second floating gates, respectively, to simultaneously adjust the voltages stored on the floating gates to keep them within a desired voltage range.

摘要： Architecture that monitors interaction data (e.g., search queries, query results and click-through rates), and provides users with links to other users that fall into similar categories with respect to the foregoing monitored activities (e.g., providing links to individuals and groups that share common interests and/or profiles). A search engine can be interactively coupled with one or more social networks, and that maps individuals and/or groups within respective social networks to subsets of categories associated with searches. A database stores mapped information which can be continuously updated and reorganized as links within the system mapping become stronger or weaker. The architecture can comprise a social network system that includes a database for mapping search-related information to an entity of a social network, and a search component for processing a search query for search results and returning a link to an entity of a social network based on the search query.

摘要： A system enables metadata to be gathered about a data store beginning from the creation and generation of the data store, through subsequent use of the data store. This metadata can include keywords related to the data store and data appearing within the data store. Thus, keywords and other metadata can be generated without owner/creator intervention, with enough semantic meaning to make a discovery process associated with the data store much easier and efficient. Usage of or communication regarding a data store are monitored and keywords are extracted from the usage or communication. The keywords are then written to otherwise associated with metadata of the data store. During searching, keywords in the metadata are made available to be used to attempt to match query terms entered by a searcher.

摘要： In one embodiment, datasets are stored in a catalog. The datasets are enriched by establishing relationships among the domains in different datasets. A user searches for relevant datasets by providing examples of the domains of interest. The system identifies datasets corresponding to the user-provided examples. The system them identifies connected subsets of the datasets that are directly linked or indirectly linked through other domains. The user provides known relationship examples to filter the connected subsets and to identify the connected subsets that are most relevant to the user's query. The selected connected subsets may be further analyzed by business intelligence/analytics to create pivot tables or to process the data.

摘要： A model for mapping the raw text representation of a text object to a vector space is disclosed. A function is defined for computing a similarity score given two output vectors. A loss function is defined for computing an error based on the similarity scores and the labels of pairs of vectors. The parameters of the model are tuned to minimize the loss function. The label of two vectors indicates a degree of similarity of the objects. The label may be a binary number or a real-valued number. The function for computing similarity scores may be a cosine, Jaccard, or differentiable function. The loss function may compare pairs of vectors to their labels. Each element of the output vector is a linear or non-linear function of the terms of an input vector. The text objects may be different types of documents and two different models may be trained concurrently.
