    Abstract: Provided are a computer program product, system, and method for using classifications from text to determine instances of graphical element types to include in a template layout for digital media output. Text is processed to determine classifications. The determined classifications of the text are inputted to a machine learning module to output instances for graphical element types. The outputted instances of the graphical element types are rendered in a user interface for a user to select. User selection is received of one of the instances rendered in the user interface for each of the graphical element types. The text with the user selected instances for the graphical element types are rendered in a template layout. The template layout including the text rendered with the user selected instances for the graphical element types is rendered in an output layout of digital media.

The processor(s) identifies upcoming event(s), within a given temporal period, in which the user will participate. The processor(s) determines that the current condition of the user will negatively impact at least one event of the upcoming event(s). The processor(s) generates action(s) comprising a change to the event, where the action(s) is executed by interacting with one or more applications deployed on the one or more target computer resources (accessible to the one or more processors via a network connection).

  • Patent number: 10769794
    Abstract: A method of object detection includes obtaining a set of images depicting overlapping regions of an area containing a plurality of objects. Each image includes input object indicators defined by input bounding boxes, input confidence level values, and object identifiers. The method includes identifying candidate subsets of input object indicators in adjacent images. Each candidate subset has input overlapping bounding boxes in a common frame of reference, and a common object identifier. The method includes adjusting the input confidence levels for each input object indicator in the candidate subsets; selecting clusters of the input object indicators satisfying a minimum input confidence threshold, having a common object identifier, and having a degree of overlap satisfying a predefined threshold; and detecting an object by generating a single output object indicator for each cluster, the output object indicator having an output bounding box, an output confidence level value, and the common object identifier.

  • Patent number: 10740569
    Abstract: Processors are configured to analyze message text content to determine whether the text content proposes a meeting event at a specified location and a specified time. In response to determining that the text content proposes said meeting event, processors determine whether a meeting is possible at the specified location and the specified time as a function of forum availability. In response to determining that the meeting is possible, some processors generate a confirming appointment message comprising text content that identifies creation of a meeting event at the meeting place at the specified location and at the specified time. In response to determining that the meeting is not possible, processors create an alternative meeting proposal message that includes alternative text content, including an alternative, different location or an alternative, different time.
