....below we use non negative coecients constrained to sum to 1. Experimental results on using di erent types of coecients (not shown here) indicate that using unconstrained coecients produces almost identical estimates in practice to the constrained case (agreeing with the results reported in [4] for regression) This general approach of learning model weights on a validation data set is known as stacking in the machine learning and statistics literature [28] and has been demonstrated to provide substantially improved predictive power over individual models for both regression [4] and ....
.... in [4] for regression) This general approach of learning model weights on a validation data set is known as stacking in the machine learning and statistics literature [28] and has been demonstrated to provide substantially improved predictive power over individual models for both regression [4] and density estimation [27] Our adaptation of stacking to the query approximation problem is quite straightforward. The main di erence with prior work on model combining (e.g. 27] is in optimization with respect to the query distribution (Q) In previous work the model coecients were ....

....method that is known to frequently create a more accurate ensemble than individual components, bagging [Breiman1996a] Bagging works by training each classifier on a random sample from the training set. Bagging has the important advantage that it is effective on unstable learning algorithms [Breiman1996b] where small variations in parameters can cause huge variations in the learned theories. This is the case with ILP. A second advantage is that it can be implemented in parallel trivially. Further details about our bagging approach within ILP, as well as our experimental methodology, can be found ....

....components, bagging [6] Bagging works by training each classifier on a random sample from the training set. In contrast to other well known techniques for ensemble generation, such as boosting [12] bagging has the important advantage that it is effective on unstable learning algorithms [7], where small variations in parameters can cause huge variations in the learned theories. This is the case with ILP. A second advantage is that it can be implemented in parallel trivially. We contrast bagging with a method we name different seeds, where we try to take advantage of the ....
....proposed for decision trees, where gains have been seen up to 25 classifiers. In our experiments we decided to extend our analysis up to 100 classifiers. The last problem concerns the combination algorithm. An effective combining scheme is often to simply average the predictions of the network [1, 7, 17, 18]. An alternate approach relies on a pre defined voting threshold. If the number of theories that cover an example is above or equal to the threshold, we say that the example is positive, otherwise the example is negative. Thresholds may range from i to the ensemble size. A voting threshold of 1 ....

....classifiers into an ensemble meta classifier by learning how they predict, i.e. by observing their input output behavior. 16 Several methods for integrating ensembles of models have been studied, including techniques that combine the set of models in some linear fashion [ Ali Pazzani, 1996; Breiman, 1994; 1996; Freund Schapire, 1995; Krogh Vedelsby, 1995; LeBlanc Tibshirani, 1993; Littlestone Warmuth, 1989; Opitz Shavlik, 1996; Perrone Cooper, 1993; Schapire, 1990; Tresp Taniguchi, 1995 ] techniques that employ referee functions to arbitrate among the predictions generated by the ....
