20120260165 | RECOMMENDING CONTENT - A method for recommending content items to a user is provided. It includes: (i) receiving one of at least an acceptance input and a rejection input from a user in relation to content presented to the user; (ii) in response to an acceptance input, rendering the presented content, or in response to a rejection input, selecting fresh content for presentation; and, (iii) repeating steps (i) and (ii) until a acceptance input is received. Content is selected in dependence on a associated probability associated with that content. The probability is increased in response to an acceptance input, the increase being determined in part on a measure of a predicted reduction in user satisfaction that would be associated with an additional rejection input. | 10-11-2012 |
20140012956 | REPLICATING DATA - The present invention concerns the replication of data, in particular the replication of data in a peer-to-peer network of mobile devices. Each device stores a plurality of data items. When two devices come into range, a decision as to whether to replicate a data item is made in dependence the extent to which that data item has been requested by other devices, and (b) the extent to which that data item is replicated on other devices. In this way, both the demand and supply of a data item are taken into account. | 01-09-2014 |

20140372480 | INTERACTIVE CONTENT SEARCH USING COMPARISONS - In interactive content search through comparisons, a search for a target object in a database is performed by finding the object most similar to the target from a small list of objects. A new object list is then presented based on the earlier selections. This process is repeated until the target is included in the list presented, at which point the search terminates. A solution to the interactive content search problem is provided under the scenario of heterogeneous demand, where target objects are selected from a non-uniform probability distribution. It has been assumed that objects are embedded in a doubling metric space which is fully observable to the search algorithm. Based on these assumptions, an efficient comparison-based search method is provided whose cost in terms of the number of queries can be bounded by the doubling constant of the embedding c, and the entropy of demand distribution, H. More precisely, the present principles show that the average search costs scales C | 12-18-2014 |
20150088992 | CONTROLLING PEER SOJOURN TIME IN FILE SHARING SYSTEMS - A method for controlling the average time a peer spends in a swarm of peers in a file sharing system includes first establishing an autonomous mode of operation in the swarm of peers. In the autonomous mode, peers communicate only with other peers in their swarm in order to gain access to pieces of a desired file. If the swarm size meets a threshold size, then the file sharing system switches to a universal mode. In a universal mode, peers from one swarm are permitted to exchange desired file pieces with other peers in other swarms. If the desired file pieces held by peers within a swarm meets a threshold number, then the file sharing system transitions back to the autonomous mode of operation. | 03-26-2015 |
20150120762 | COMPARISON-BASED ACTIVE SEARCHING/LEARNING - A method is provided for performing a content search through comparisons, where a user is presented with two candidate objects and reveals which is closer to the user's intended target object. The disclosed principles provide active strategies for finding the user's target with few comparisons. The so-called rank-net strategy for noiseless user feedback is described. For target distributions with a bounded doubling constant, rank-net finds the target in a number of steps close to the entropy of the target distribution and hence of the optimum. The case of noisy user feedback is also considered. In that context a variant of rank-nets is also described, for which performance bounds within a slowly growing function (doubly logarithmic) of the optimum are found. Numerical evaluations on movie datasets show that rank-net matches the search efficiency of generalized binary search while incurring a smaller computational cost. | 04-30-2015 |
