  • Publication number: 20230195841
    Abstract: Methods and systems are disclosed for determining a performance shift due to an applied condition, excluding other, e.g., environmental, factors. One mechanism for determining a performance shift due to an applied condition involves using two datasets (e.g., a control dataset and a test dataset) for two different populations. A training dataset is used to train a machine learning model to build a control dataset to be used in a second machine learning model together with a test dataset to determine whether a performance shift between the two datasets is due to the condition that was applied to the test dataset.

  • Publication number: 20230169394
    Abstract: Methods and systems are described herein for a mechanism for detecting model bias using a test model to compare predictions for specific categories of data. Thus, the system may detect category-specific model bias and/or present alternative predictions, for example, via overfitted and alternative machine learning models. Another mechanism for detecting model bias is to use residual data from predictions obtained from a machine learning model as the machine learning model processes different datasets (e.g., a training dataset and a compare dataset).

  • Patent number: 9697908
    Abstract: Various implementations described herein may refer to and may be directed to non-discharging read-only memory cells. For instance, in one implementation, an integrated circuit may include a read-only memory (ROM) array including a plurality of ROM cells arranged into a column, where the column is disposed proximate to a bit line and to a reference voltage line. The plurality of ROM cells arranged into the column may include a plurality of non-discharging ROM cells positioned adjacently to one another, where each non-discharging ROM cell has a source terminal, a drain terminal, or both coupled to at least one adjacent non-discharging ROM cell. In addition, the plurality of non-discharging ROM cells may be coupled to the bit line using two or fewer connections.

  • Publication number: 20150215166
    Abstract: The invention discloses a computer implemented network resource monitoring method in a network that comprises a service profiler which detects plurality of services hosted on host servers over the network, and creates the unique profiles for each of the plurality of detected services on a local service profiles database using a service profiles database. In case of any changes in the IT configuration of the detected service, the service profiler requests a profile assistant to change IT configuration, wherein the profile assistant compares profile presets and the local service profiles database to make the necessary changes.
