摘要： The present invention relates to a new error control paradigm in a packet switched network that is particularly advantageous for multicast transmission.
A transmission Status vector TSV (T) is updated at the sender side whenever a new outgoing data packet (Dj-1) is scheduled for transmission. A corresponding Reception Status Vector RSV (R) is similarly updated at the receive side whenever a new incoming and correctly indexed data packet (Dj-1) is validly received.
As soon as a missing or corrupted data packet (Dj) is detected, the update of the RSV is suspended. A request is then sent to the sender to get the current TSV's value, or a part thereof. The erroneous data packet is then recovered from the current TSV'S value (sk,m), from the lastly updated RSV'S value (sj-1), and from otherwise validly received data packets (Dj+1, ..., Dk).
The present invention more specifically relates to a transmitting unit (100) and a receiving unit (200) implementing that paradigm, and correspondingly to a method for protecting a flow of indexed data packets against data lost or data corruption, and a method for recovering a missing or corrupted data packet within a flow of indexed data packets.

摘要： A recommended method for selecting content items to be recommended to a user or users includes obtaining a data set of content items in which items are included irrespective of whether or not they have associated user feedback indicating relevance to users. User feedback associated with content items in the data set is used to estimate (a) a user-feature matrix Q of q_{u, k}, with K_u values of k (k = 1, ..., K_u) per user u, representing user profiles and acquired over a first time period prior to a time at which content items are to be recommended to the user or users; and (b) a content-feature matrix P of p_{i, l}, with L_i values of 1 (1=1, ..., L_i) per item i, representing content profiles and acquired over a second time period prior to the time at which content items arc to be recommended to the user or users. The user-feature matrix Q and the content-feature matrix P are used to build a matrix R of estimated rating values r_{i, u} where r_{i, u} = f (q_{u, k}, p_ {i, l}). Higher ranked content items of the matrix R are selected to be recommended to the user or users.
The selected recommendations may be used to determine which content items are to be pre-loaded and /or cached for later access by the user or users.
