Sample text

Sigmoidal functions are often used in machine learning for smooth transitions [9]. The sigmoidal function sigmoidal(d, k, m) has a tuning parameter k, which is used to determine the flatness of the smoothing function. 5m. 5m. 2 Limiting Case-Base Size One of the drawbacks of using CBR as a prediction strategy is the scalability issue of CBR: the larger the case-base, the more time it takes to make a decision; for every prediction request, similarity has to be calculated between the current request and all cases in the case-bases.

So that, topics are arranged in a doubled linked tree (parent, child) and semantic distance between two nodes of the tree is calculated as the number of arcs between them. In this case relevance is inverse to the semantic distance (a short distance can belong to “high” relevance scale). e. a web page, an SMS account, a MS Word application, etc). ). A physical device can hold many virtual places. For users can be contacted, vPlaces need an electronic address (e_address) and a content delivery method (similar to a driver).

The limited case-base size did not have any negative effects on the accuracy, on the contrary, accuracy increased more with limited case-base sizes after the second week than with unlimited sizes. 20 Mark van Setten et al. 2 Cross-Validation Cross-validation in the MovieLens dataset (see Table 3) shows that the CBR-based strategy does perform well in MovieLens, although not as well as in the TiV dataset. Sometimes, the rule-based strategy still out-performs the CBR-based strategy; however, even in those situations the CBR-based strategy is still better than the best individual prediction technique, making it an adequate prediction strategy.
