    Abstract: A method for intelligently distributing messages across multiple devices and associated chat applications is disclosed. In one embodiment, such a method includes registering multiple devices and associated chat applications to receive intelligent distribution of messages. The method monitors, using an agent, a message copied from a first device of the multiple devices to a clipboard. The method automatically analyzes content of the message to determine which other devices and associated chat applications of the plurality are eligible to receive the message. The message is then distributed to other devices and associated chat applications that are deemed eligible to receive the message. In certain embodiments, the message originates from a first chat application of a first type and the message is distributed to a second chat application of a second type that is different from the first type. A corresponding system and computer program product are also disclosed.

  • Publication number: 20230394373
    Abstract: The technology of this disclosure relates to a method, an apparatus, a device, a storage medium, and a system for determining a collection period. The technology relates to the field of machine learning technologies. In this disclosure, a machine learning model is obtained by using a training dataset collected based on candidate collection periods of X features, and a candidate collection period of each of the X features is determined as a target collection period of each feature based on the obtained machine learning model and a first condition. Because the target collection period of each feature is greater than a minimum collection period of each feature, subsequently, if data is collected based on the target collection period of each feature, an amount of the collected data is reduced, to reduce collection load of a device and memory occupied by sampled data, thereby reducing time redundancy.
