  • Publication number: 20190370394
    Abstract: Methods and apparatuses are described for automated computer text classification and routing using artificial intelligence transfer learning. A server trains a word embedding model using one-hot vectors of word pairs from a filtered first corpus of unstructured computer text and a filtered second corpus of unstructured computer text, using an artificial intelligence neural network. The server trains a long short-term memory model using vector matrices that correspond to sentences in the filtered second corpus of unstructured computer text, and labels. The server receives a message, generates a matrix for each sentence in the message by applying the trained word embedding model, generates one or more labels, and a probability for each label, for each sentence in the message by applying the trained long short-term memory model, and routes the message to a second client computing device based upon an assigned label.

  • Patent number: 10496731
    Abstract: A method, system, and processor-readable storage medium are directed towards calculating approximate order statistics on a collection of real numbers. In one embodiment, the collection of real numbers is processed to create a digest comprising hierarchy of buckets. Each bucket is assigned a real number N having P digits of precision and ordinality O. The hierarchy is defined by grouping buckets into levels, where each level contains all buckets of a given ordinality. Each individual bucket in the hierarchy defines a range of numbers—all numbers that, after being truncated to that bucket's P digits of precision, are equal to that bucket's N. Each bucket additionally maintains a count of how many numbers have fallen within that bucket's range. Approximate order statistics may then be calculated by traversing the hierarchy and performing an operation on some or all of the ranges and counts associated with each bucket.

  • Patent number: 10474674
    Abstract: Embodiments of the present disclosure provide techniques for using an inverted index in a pipelined search query. A field searchable data store is provided that comprises a plurality of event records, each event record comprising a time-stamped portion of raw machine data. Responsive to the reciept of an incoming search query, the search engine accesses an inverted index, wherein each entry in the inverted index comprises at least one field name, a corresponding at least one field value and a reference value associated with each field name and value pair that identifies a location in the data store where an associated event record is stored. Once the inverted index is accessed, it can be used to filter out a subset of the plurality of event records, wherein the subset comprises one or more event records with corresponding reference values in the inverted index.
