  • Patent number: 12682108
    Abstract: A candidate attribute combination of a first data set is identified, such that the candidate attribute combination meets a data type similarity criterion with respect to a collection of data types of sensitive information for which the first data set is to be analyzed. A collection of input features is generated for a machine learning model from the candidate attribute combination, including at least one feature indicative of a statistical relationship between the values of the candidate attribute combination and a second data set. An indication of a predicted probability of a presence of sensitive information in the first data set is obtained using the machine learning model.

  • Patent number: 11797705
    Abstract: A generative adversarial network (GAN) may be implemented to recognize named entity types in detection of sensitive information in datasets. The GAN may include a generator and a discriminator. The generator may be trained to produce synthetic data to include information that simulates named entity types representing the sensitive information. The discriminator may be fed with real data that are known to include the sensitive information (as positive examples), together with the synthetic data that simulate the sensitive information (as negative examples), to train to classify the real vs. synthetic data. In field operations, the discriminator may be deployed to perform named entity type recognition to identify data having the sensitive information. The generator may be deployed to provide anonymous data in lieu of real data to facilitate sensitive information sharing and disclosure.

  • Publication number: 20220412557
    Abstract: The present disclosure relates to apparatuses and methods that are useful for one or more aspects of a power production plant. More particularly, the disclosure relates to combustor apparatuses and methods for a combustor adapted to utilize different fuel mixtures derived from gasification of a solid fuel.

  • Patent number: 8146047
    Abstract: An automated design process using a computer system includes identifying a set of timing endpoints in a circuit defined by a machine-readable file. Values of slack in the estimated arrival times for the timing endpoints are assigned. Probability distribution functions, such as Gaussian distributions, are assigned for the respective values of slack, and are combined. The combination of probability distribution functions represents a measure of circuit performance. The measure is computed for alternative implementations of the circuit, and used to identify an alternative more likely to meet timing constraints.

  • Patent number: 6132109
    Abstract: This invention provides a method for displaying circuit analysis results corresponding to parts of the circuit near the portion of the hardware description language (HDL) specification that generated that part of the circuit. The invention also includes a method for using probe statements in the HDL specification to mark additional points in the initial circuit that should not be eliminated during optimization. This improves the ability to display circuit analysis results near the appropriate part of the HDL specification.

  • Patent number: 5937190
    Abstract: A digital circuit is synthesized from a text description of a digital system. During synthesis, a parse tree with parse nodes is constructed and retained. The relationship between the parse nodes and the circuit elements synthesized from those parse nodes is retained. Using that relationship, analysis results associated with circuit elements can be related to the text that generated those circuit elements. In particular, the analysis results can be used to set the display characteristics, such as font or size, of the text associated with those results.
