    Abstract: Aspects of activation function computation for neural networks are described herein. The aspects may include a search module configured to receive an input value. The search module may be further configured to identify a data range based on the received input value and an index associated with the data range. Meanwhile, a count value may be set to one. Further, the search module may be configured to identify a slope value and an intercept value that correspond to the input value. A computation module included in the aspects may be configured to calculate an output value based on the slope value, the intercept value and the input value. In at least some examples, the process may be repeated to increase the accuracy of the result until the count of the repetition reaches the identified index.

  • Patent number: 10423640
    Abstract: The use of multiple logical data models to expose a data storage system. Each logical data model may expose the data storage system using a semantic mapping set that maps sets of entities or attributes of the respective logical data model to corresponding sets of entities or attributes of the physical data model or perhaps directly to the data storage system itself. Each logical data model might serve a different vertical, and have a particular modelling notation selected by the logical data model provider. The mapping may also translate different logical modelling notations into a common logical modelling notation for use in communicating with the physical data model. The system may account for the lifecycle of the logical data model including birth or retirement of logical data model entities, and merging or splitting of logical data models.
