  • Patent number: 11954565
    Abstract: A technology is described for automating deployment of a machine learning model. An example method may include receiving, via a graphical user interface, credentials for connecting to a data store containing a plurality of datasets and connecting to the data store using the credentials. A selection of a target metric to predict using the machine learning model can be received, via the graphical user interface, and datasets included in the plurality of datasets that correlate to the target metric can be identified by analyzing the datasets to identify an association between the target metric and data contained within the datasets. The datasets can be input to the machine learning model to train the machine learning model to generate predictions of the target metric, and the machine learning model can be deployed to computing resources in a service provider environment to generate predictions associated with the target metric.

  • Patent number: 4986755
    Abstract: It is useful to a sonar instructor to have a device which simulates Doppler hifting of recorded sonar signals. Such a device can consist of a digitizer operating at a fixed rate storing data in RAM. A variable read rate is calculated based on the desired Doppler shifting. Data are read from RAM at a variable rate higher or lower than the fixed rate and converted D to A before being sent to the student sonar operator.
