  • Publication number: 20240070434
    Abstract: An information system provides a conversational knowledge base for responding to user queries. The information system incorporates contemporaneous advancements in NLP and deep learning to create the conversation knowledge base from its documents, which may be obtained from various sources. Domain-specific information is extracted and generated from the documents substantially without human intervention. From the domain-specific information, precise answers to synthesized questions are generated using transformer-based deep learning models.

  • Patent number: 8099733
    Abstract: A tree-structured index to multidimensional data is created using naturally occurring patterns and clusters within the data which permit efficient search and retrieval strategies in a database of DNA profiles. A search engine utilizes hierarchical decomposition of the database by identifying clusters of similar DNA profiles and maps to parallel computer architecture, allowing scale up past to previously feasible limits. Key benefits of the new method are logarithmic scale up and parallelization. These benefits are achieved by identification and utilization of naturally occurring patterns and clusters within stored data. The patterns and clusters enable the stored data to be partitioned into subsets of roughly equal size. The method can be applied recursively, resulting in a database tree that is balanced, meaning that all paths or branches through the tree have roughly the same length.

  • Publication number: 20100100221
    Abstract: A method for adjusting a data set defining a set of process runs, each process run having a set of data corresponding to a set of variables for a wafer processing operation is provided. A model derived from a data set is received. A new data set corresponding to one process run is received. The new data set is projected to the model. An outlier data point produced as a result of the projecting is identified. A variable corresponding to the one outlier data point is identified, the identified variable exhibiting a high contribution. A value for the variable from the new data set is identified. Whether the value for the variable is unimportant is determined. A normalized matrix of data is created, using random data and the variable that was determined to be unimportant from each of the new data set and the data set. The data set is updated with the normalized matrix of data.

  • Patent number: 7130767
    Abstract: A computer-implemented data presentation technique for presenting a set of expected failure states of system-related constructs pertaining to a plasma processing system is disclosed. The technique includes receiving a set of indicia pertaining to a first system-related construct of said system-related constructs. The technique also includes computing, in accordance with a first sub-method and responsive to said receiving said first set of indicia, a first expected failure state value. The technique further includes computing a first normalized expected failure state value in accordance with a first weight; correlating said first normalized expected failure state value to a first color; and displaying said first color in a cell of an n-dimensional matrix, wherein n is a number greater than 1.

  • Patent number: 7078344
    Abstract: A system and method for planarizing and controlling non-uniformity on a patterned semiconductor substrate includes receiving a patterned semiconductor substrate. The patterned semiconductor substrate having a conductive interconnect material filling multiple features in the pattern. The conductive interconnect material having an overburden portion. A bulk of the overburden portion is removed and a remaining portion of the overburden portion has a non-uniformity. The non-uniformity is mapped, optimal solution determined and a dynamic liquid meniscus etch process recipe is developed to correct the non-uniformity. A dynamic liquid meniscus etch process, using the dynamic liquid meniscus etch process recipe, is applied to correct the non-uniformity to substantially planarize the remaining portion of the overburden portion.
