  • Patent number: 11961115
    Abstract: In some examples, a computing device may receive data from a plurality of groups of data sources. The computing device may access a plurality of data synthetization machine learning models configured for generating synthetic data. Respective ones of the data synthetization machine learning models may correspond to respective ones of the groups of data sources. The computing device generates first synthetic data by inputting, to a first data synthetization machine learning model, first data received from a first data source group, and generates second synthetic data by inputting, to a second data synthetization machine learning model, second data received from a second data source group. The computing device determines an allocation of resources based at least in part on comparing the first data and the first synthetic data with the second data and the second synthetic data.

  • Publication number: 20230410880
    Abstract: A system that calibrates timing relationships between signals involved in performing write operations is described. This system includes a memory controller which is coupled to a set of memory chips, wherein each memory chip includes a phase detector configured to calibrate a phase relationship between a data-strobe signal and a clock signal received at the memory chip from the memory controller during a write operation. Furthermore, the memory controller is configured to perform one or more write-read-validate operations to calibrate a clock-cycle relationship between the data-strobe signal and the clock signal, wherein the write-read-validate operations involve varying a delay on the data-strobe signal relative to the clock signal by a multiple of a clock period.

  • Patent number: 11734312
    Abstract: A behavior detection module receives a training database and applies a transformation to the attributes that improves the uniformity of the values associated with each attribute. The transformed training database is used to construct a random forest classifier (RFC). The RFC includes a plurality of decision trees and generates a classification label estimate for a data entry with a plurality of attributes. The classification label estimate is determined based on classification estimates from the plurality of decision trees. Each parent node of a decision tree is associated with a condition of a transformed attribute that directs the data entry to a corresponding child node depending on whether the condition is satisfied or not. The data entry is directed through the tree to one out of a set of leaf nodes, and a classification label associated with the leaf node.

    Abstract: A packet forwarding network may include spine and leaf switches that forward network traffic between end hosts. The packet forwarding network may be implemented on multiple network racks in a rack-based system. A controller may control the underlying spine and leaf switches to form on-premise virtual private cloud (VPC) resources. In particular, the controller may form enterprise VPC (EVPC) tenants, each having a virtual router that performs routing between different segments within the corresponding EVPC tenant. The different segments may separately include web, application, and database servers, as end hosts. The controller may form a system VPC tenant having a virtual system router that performs routing between different EVPC tenants. A segment in an internal VPC tenant formed by the controller and/or an external VPC tenant formed by the controller may provide external network access for one or more of the EVPC tenants.

  • Patent number: 11256568
    Abstract: The present invention facilitates efficient and effective utilization of storage management features. In one embodiment, a memory device comprises a memory interface, an ECC generation component, and storage components. The memory interface is configured to receive an access request to an address at which data is stored. The memory interface can also forward responses to the request including the data and ECC information associated with the data. The ECC generation component is configured to automatically establish an address at which the ECC information is stored based upon the receipt of the access request to an address at which data is stored. In one exemplary implementation, the internal establishment of the address at which the ECC information is stored is automatic. The storage components are configured to store the information.

  • Publication number: 20210133149
    Abstract: In some embodiments, a meta-data inspection data store may contain hierarchical components and subcomponents of an industrial asset and define points of interest. An industrial asset inspection platform may access that information and generate an inspection plan, including an association of at least one sensor type with each of the points of interest. The platform may then store information about the inspection plan in an inspection plan data store and receive inspection data (e.g., from a manual inspection, from an inspection robot, from a fixed sensor, etc.). A smart tagging algorithm may be executed to associate at least one point of interest with an appropriate portion of the received inspection data based on information in the inspection plan data store.

  • Patent number: 10956426
    Abstract: A behavior detection module constructs a random forest classifier (RFC) that takes into account asymmetric misclassification costs between a set of classification labels. The classification label estimate is determined based on classification estimates from the plurality of decision trees. Each parent node of a decision tree is associated with a condition of an attribute that splits a parent node into two child nodes by maximizing an improvement function based on a training database. The improvement function is based on an asymmetric impurity function that biases the decision tree to decrease the error for a label with high misclassification cost over the other, at the cost of increasing the error of the other label with a lower misclassification cost.
