    摘要： A recommender system uses an activity decision tree to model the changes in a user's behavior according to a plurality of time-related features. The system determines historical activities for the user, and generates a decision tree for the user's historical activities. Each leaf node of the decision tree is associated with an activity-prediction model that computes a probability for a corresponding activity. The system selects a path of the decision tree from a root node to a leaf node of the decision tree based on a target time. The selected path traverses two or more non-leaf nodes that are each associated with a temporal decision model that compares the target time against a temporal classifier. The system then determines a probability for a user activity based on an activity-prediction model of the selected path.

    摘要： A method is described for efficiently determining total end-to-end distortion of a pre-compressed data stream, such as video streams or other media streams, at the time of delivery over a lossy-network, and for providing adaptive error-resilient delivery schemes based on distortion estimates. The methods can be utilized with single or multilayer packet streams and are particularly well suited for video streams. By way of example, distortion estimates are performed by generating side-information at the time of data stream compression, wherein the side-information is used in conjunction with information about the network status to determine an estimated distortion for the group of packets when the data stream is transported over the network to a destination end. This estimation may be utilized within described resiliency techniques in which the error correction mechanism is selected in response to the estimated distortion, which may be additionally refined in reference to cost factors.

    摘要： In one embodiment, a process determines a size of a video unit (e.g., frame) to transmit from a sender to a receiver across a communication channel for an associated video stream, and also determines an updated packet loss rate on the channel. In response, the process may dynamically determine both a number N of video data packets and a number M of forward error correction (FEC) packets to transmit for the video unit based on the size of the video unit, the updated packet loss rate on the channel, and an error resilience requirement for the video stream. In an illustrative embodiment, N and M are determined during transmission of the video stream through a look-up operation into a table indexed by the size of the video unit and the updated packet loss rate as co-indices, the co-indices co-indexing a pre-determined N and M pair.

    摘要： An automatic calendar-managing system automatically updates a user's schedule in response to schedule-modifying events. During operation, the system can detect a schedule-modifying event, which can include an event that is likely to require the user to modify a set of scheduled activities. The system then generates a schedule modification, which includes at least one change to the user's set of scheduled activities, to account for the schedule-modifying event. The system can reschedule the user's set of scheduled activities to accommodate the schedule modification.
