Abstract: This disclosure provides a computer-program product, system, method and apparatus for accessing a representation of a category or item and accessing a set of multiple transactions. The transactions are processed to identify items found amongst the transactions, and the items are ordered based on an information-gain heuristic. A depth-first search for a group of best association rules is then conducted using a best-first heuristic and constraints that make the search efficient. The best rules found during the search can then be displayed to a user, along with accompanying statistics. The user can then select rules that appear to be most relevant, and further analytics can be applied to the selected rules to obtain further information about the information provided by these rules.

Abstract: Disclosed are a retransmission method, a base station, and a user device in a multicast system. In order to reduce uplink signaling resource, a new MNI (Multiple NACK Indicator) message is added to an uplink common feedback channel in an existing E-MBMS system. The MNI message enables decision of an XOR retransmission group which satisfies the XOR retransmission condition. As compared to a conventional XOR retransmission, the number of uplink signalings does not depend on the number of receivers. That is, when a plenty of receptions are present, it is possible to significantly reduce uplink signalings.
