  • Publication number: 20210133683
    Abstract: Techniques are provided for implementing a probabilistic system and architecture to predict and optimize particular user activity. In one technique, opportunity application data that indicates multiple applications to multiple opportunities is stored. Tracking data that indicates, for each opportunity, a number of reviewer actions with respect to applications to the opportunity is stored. Based on the tracking data, one or more machine learning techniques are used to learn parameters of a model that takes, as input, a number of weighted applications of an opportunity and generates, as output, a prediction of a confirmed hire for the opportunity. A particular opportunity is identified and a first number of reviewer actions with respect to the particular opportunity is determined. A second number of weighted applications for the particular opportunity is generated based on the first number. The second number is input into the model to generate a score for the particular opportunity.

  • Publication number: 20210072240
    Abstract: Described herein are improvements relating to IGF-1 analysis, adjustment and disease management of non-neurological and/or neurological conditions. More specifically, methods relating to the clinical application of cyclic glycine-proline (cGP) biomarker for prediction of risk and recovery of non-neurological and/or neurological conditions with IGF-1 dysfunction and the use of a cGP containing organic or plant based material such as concentrated extract of blackcurrant anthocyanins (BCA) for the treatment of same. The methods more accurately measure IGF-1 function in vivo indirectly using cGP and cGP/IGF-1 ratio along with a means to adjust cGP and cGP/IGF-1 ratio (and hence active IGF-1 concentration), and specific treatment methods for individuals with a lower or reduction of cGP level relative to a standard set of baseline data.

  • Publication number: 20200402012
    Abstract: A technical problem of multi-objective optimization of job applications redistribution in an online connection network system is addressed by incorporating monetary value of job applications as a signal into a ranker for ranking jobs with respect to a member profile in job search and recommendations. The monetary value of job applications is used in addition to the relevance signal and is determined by executing a machine learning model that accounts for the covariates that could impact monetary value of an application for a job.

  • Publication number: 20190019158
    Abstract: In some embodiments, the disclosed subject matter involves a system and method relating to evaluating the quality of recommendations provided to a member of a recommendation service. Techniques and embodiments described herein may be applied to various recommendation services/engines. Middleware may be used to receive a member ID from a user and forward the member ID to a recommendation engine without the user having to log on as the member to access recommendations. Results of the recommendation engine may be received by the middleware and forwarded to the user for the selected member to be displayed proximate to the member profile. The user may annotate the recommendations with a relevancy rating to evaluate the quality of the recommendation engine and provide input to retrain recommendation models of the engine. Other embodiments are described and claimed.

  • Publication number: 20110196746
    Abstract: Systems, methods, and computer storage media having computer-executable instructions embodied thereon that provide insight to advertisers that participated in online advertiser auctions. A system receives data from one or more advertiser auctions and stores the data in a log. The log is queried for a sample of the data from the advertiser auctions. Data is extracted from the sample regarding advertisements submitted by the advertisers that participated in the advertiser auctions. Based on the data extracted from the sample, a report is generated that summarizes statistics and feedback regarding the advertisements that participated in the advertiser auctions. The report is displayed to a user. In embodiments, the report is automatically generated and displayed to the advertisers that participated in the advertiser auctions.

  • Patent number: 7640252
    Abstract: Systems and methods are provided for generating prediction queries to help a user build and execute prediction queries. A user interface (UI) is provided that is easy to use and understand in connection with the generation of a prediction query for data mining. The UI can be instantiated from a variety of disparate sources that may request query building services. While prediction queries and relational queries are quite different, the UI enables prediction queries to be built in a manner that is similar to the way relational queries are built. In one embodiment, the main screen of the UI includes four main components: (1) a table column mapping area, (3) a selection grid area, (4) a query text display area and (5) a query result grid area. In one embodiment, the query text display area and the query result grid area are initially not presented to the user.
