Establishing value mappings using statistical models and user feedback
2005
Proceedings of the 14th ACM international conference on Information and knowledge management - CIKM '05
Preserved Fulltext
It then finds the matching values by computing the distances between the models while refining the models using user feedback through iterations. ...
Our experimental results suggest that our approach successfully establishes value mappings even in the presence of opaque data values and thus can be a useful addition to the existing data integration ...
Our algorithm uses the statistical dependency model among values (e.g., value co-occurrence frequency or entropy) as the basis for establishing value mappings. ...

In our setting, the channel between the base station and each user is modeled by a two-state Markov chain and the scheduled user sends back an ARQ feedback signal that arrives at the scheduler with a random ...
Establishing an equivalence between the two-user system and a genie-aided system, we obtain a simple closed form expression for the sum capacity of the Markov-modeled downlink. ...
Note that since in each slot one and only one user is scheduled, is neither empty nor has multiple values, i.e., with bit 0 mapped to NACK and bit 1 to ACK feedback. ...

Traditional recommendation algorithms on Collaborative Filtering (CF) mainly focus on the rating prediction with explicit ratings, and cannot be applied to the top-N recommendation with implicit feedbacks ...
To tackle this problem, we propose a new collaborative filtering approach namely Maximize MAP with Matrix Factorization (MFMAP). ...
By using the smoothing function approximation to replace the non-smooth part of the MAP, the objective function can be optimized using an optimization method, and the parameters of the model are trained ...

For each query, the resulting document IDs are treated as terms and the score or rank of the document is used as the frequency statistic. An index of documents retrieved by basis queries is created. ...
Models other than tf·idf use concepts such as eliteness [2, 10] and risk [14] ; those statistics are also applicable in the reverted setting. ...
