    摘要： Mixed mode inferencing is provided by creating an extension to a RETE network to handle both forward and backward chaining efficiently. The extended RETE network is traversed from a root node through intermediate nodes to the rules of the network. The intermediate nodes contain objects that have values assigned by rules, and the intermediate nodes are linked to those rules appropriately. When using the network in a backward chaining context, rules linked to the intermediate node of interest are checked to see if they are active and the rule is solvable. If not, the related rules are checked. Because the system takes advantage of the previously formed RETE network, these checks can be done at the rule nodes without the need to retest each condition.

    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.
