چکیده
This paper describes a machine learning method, called Regression on Feature Projections (RFP), for predicting a real-valued target feature, given the values of multiple predictive features. In RFP training is based on simply storing the projections of the training instances on each feature separately. Prediction of the target value for a query point is obtained through two averaging procedures executed sequentially. The ®rst averaging process is to ®nd the individual predictions of features by using the K-Nearest Neighbor (KNN) algorithm. The second averaging process combines the predictions of all features. During the ®rst averaging step, each feature is associated with a weight in order to determine the prediction ability of the feature at the local query point. The weights, found for each local query point, are used in the second prediction step and enforce the method to have an adaptive or context-sensitive nature. We have compared RFP with KNN and the rule based-regression algorithms. Results on real data sets show that RFP achieves better or comparable accuracy and is faster than both KNN and Rule-based regression algorithms. q 2000 Elsevier Science B.V. All rights reserved.

Explicit modeling of business processes and their enactment in work ̄ow systems have proved to be valuable in increasing the ef®ciency of work in organizations. We argue that enacted business processes Ð i.e. work ̄ow management systems Ð form a solid basis for adequate information support in complex and knowledge-intensive business processes. To support this claim we demonstrate results from two...
متن کاملTowards understanding and supporting creativity in design: analogies in a constrained cognitive environment
In order to show that the emergence of new ideas takes place in a "constrained cognitive environment", we conducted two experimental shrdies in a creaiive professional area: non-routine design. The first study is focused on the role of analogical reasoning in creativity and. especially, on the nature of potential "sources" of inspiration. which facilitate the evocation process. The second study...
