  • Publication number: 20210287136
    Abstract: A classification modeling system receives a request to identify a classification model from a set of classification models. The request includes a data set and specifies one or more metrics for evaluating performance of the set of classification models in classifying data from the data set. The system uses the set of classification models to generate a set of classifications and determines the performance of the set of classification models based on the set of classifications and according to the one or more metrics. Based on the performance of the set of classification models, the system selects a classification model and provides the classification model to fulfill the request.

  • Patent number: 9491619
    Abstract: A method of preauthenticating a mobile node in advance of a switch from a current point of attachment (CPoA) to a next point of attachment (NPoA) is disclosed. One or more preauthentication requests are received at the CPoA. The one or more preauthentication requests include a proxy assignment from the mobile node. Each of the one or more preauthentication requests corresponds to one of one or more possible points of attachment (PPoAs). Using the CPoA, the mobile node is preauthenticated with the one or more PPoAs using a transitivity of trust between the mobile node, the CPoA, and one or more authentication servers.

  • Patent number: 9042389
    Abstract: A gateway which provides network connectivity via network service providers. A method and apparatus can integrate the various connectivity options provided by multiple service providers and present to the user a single point of connectivity. Having more than one way of network connectivity may provide the following additional services: Link Aggregation (to increase bandwidth), Redundancy and ancillary services like TOD (time-of-day) based smart usage (to reduce costs). The access medium may be wired technologies like Cable, DSL, Fiber to wireless 4G technologies. These options may offer various link speeds, latency, reliability and cost structures. The embodiments integrate the various connectivity options provided by multiple service providers and present to the user a single point of connectivity.

  • Patent number: 4371608
    Abstract: A chalcogenide such as As.sub.2 S.sub.3 is coated on a substrate at a very low rate of deposition in a vacuum evaporator and is coated with a thin silver layer. The silver coated layer is exposed to illumination in a quantity insufficient to form an etchable layer by conventional techniques and the silver is increased by treatment with a silver-containing agent capable of depositing silver on the image, preferably in the presence of radiation. NaAgSO.sub.3 is a presently preferred agent. The resulting image-bearing layer is photo-doped by exposure to band-gap radiation and the member is then etched.
