  • Publication number: 20210125723
    Abstract: A method for processing medical examination data performed by a computing device, including determining a time interval that is last increased in a first repeating as an optimal time interval, configuring a feature matrix having a time axis according to the optimal time interval, and by using the feature matrix, setting a look-back window size to a predetermined initial size to obtain a performance evaluation result of the trained RNN-based model, second repeating increasing the look-back window size and then obtaining a second performance evaluation result of the RNN-based model trained according to the increased look-back window size until the second performance evaluation result is no longer improved, determining the look-back window size that is last increased in the second repeating as an optimal look-back window size and training the RNN-based model according to the optimal look-back window size by using the feature matrix having the optimal time interval.

  • Patent number: 10122540
    Abstract: A wireless device and method for managing a multicast group within a wireless network are disclosed. The wireless device is included in a first multicast group in which data is directly sent between member devices or data is sent using hopping between the member devices. The wireless device includes a reception unit, a determination unit, and a transmission unit. The reception unit receives a join request for joining a second multicast group from a joining device that attempts to join the second multicast group. The determination unit extracts information about the second multicast group from the join request, and determines whether the second multicast group is identical with the first multicast group based on the information about the second multicast group. The transmission unit forwards the join request to another device or sends a response to the join request to the joining device based on a result of the determination.

  • Patent number: 9509453
    Abstract: The present invention discloses a method for providing reliable multicasting service in wireless network. The disclosed method groups a plurality of receiving nodes into a plurality of receiving groups, and decides the ACK transmission time point against each receiving group, which is not overlapped with other receiving groups. The receiving node contained in each receiving group transmits ACK against the received data frame at the ACK transmission time point, which is decided according to the corresponding receiving group.
