  • Publication number: 20200364608
    Abstract: A computer-implemented method of communicating in a federated learning environment includes an aggregator and a plurality of federated learning participants that respectively maintain their own data and communicate with the aggregator. The aggregator monitors the plurality of federated learning participants for factors associated with stragglers. The federated learning participants are assigned into tiers based on the monitoring of the factors. The aggregator queries the federated learning participants in a selected tier and designates late responders as stragglers. Maximum waiting time may be defined for each tier. The aggregator applies a predicted response for drop outs including collected participants' replies and computed predictions associated with the stragglers to update a training of a federated learning model. The federated learning participants that do not respond within the designated wait time are designated as drop outs.

  • Publication number: 20200234193
    Abstract: There is disclosed a computer-implemented cloud computing scoring system. In an embodiment, a parser receives unstructured sentiment data commenting on a scored service. The parser identifies in the unstructured sentiment data a service category of the scored service. The parser selects from the unstructured sentiment data text relating to the service category and matching one or more opinionative words and phrases listed in a keyword dictionary, thereby producing a structured comment associated with the service category. The structured comment is classified as positive or negative according to a list of exemplary sentiment data sets contained in a learning seed file. The exemplary sentiment data sets are manually assigned a positive or a negative polarity. The learning seed file is configured for enhancement by the ongoing addition of structured sentiment data, the structured sentiment data commenting on the scored service and having a polarity classification.
