....using a fixed amount of memory and application specific rules for pruning nonpromising search alternatives. It was experimentally observed that beam search can significantly reduce the computation of its underlying search method [4] Beam search has been successfully applied to many problems [11, 12, 29, 35, 40]. Since both state space reduction and beam search use heuristic node pruning, the former can be regarded as an extension of the latter. The main contribution of this research to beam search is twofold. First, we extended the idea of heuristic node pruning to a depth first search algorithm and ....

....have implemented a system which automatically generates examples for a constraint stated in the theory and we have experimented with the system in the BoyerMoore theorem prover. 1.1 An Overview Examples are, in general, a very useful tool in Artificial Intelligence. Many machine learning systems [52, 33, 10, 14, 32] use examples for the tasks of generating concepts and conjectures. For instance, Winston s system [52] learns structural descriptions from examples. His system is presented with training instances positive examples and near misses of a structure (concept) to be learned such as an arch and ....

.... researchers (Matheus, 1991; Aha, 1991; Kadie, 1991; Ragavan et al. 1993) Constructing new feature by hand is often difficult (Quinlan, 1983) The goal of constructive induction is to automatically transform the original representation space into a new one where the regularity is more apparent (Dietterich Michalski, 1981; Mehra et al. 1989) thus yielding improved classification accuracy. Several machine learning algorithms perform feature construction by extending greedy, hill climbing strategies, including FRINGE (Pagallo, 1989) GREEDY3 (Pagallo Haussler, 1990) DCFringe (Yang et al. 1991) CITRE ....

....only if it is not satisfied by any of the negative examples. The learned concept is an admissible rule if and only if it is both characteristic and discriminant [DiM83,GeN87] Most learning algorithms are designed for learning admissible rules [DiM83,Mic83] A few algorithms, such as INDUCE 1. 2 [DiM81] and SPROUTER [HaM77] are designed for learning characteristic rules. DBROUGH [HuC94a, HuC94b, HSCZ94, HCH94, HCS94] can discover characteristic rules, discriminant rules and some other knowledge rules. 2.1.4 Control Strategies in Learning from Examples Induction methods can be divided into ....
....the search. These methods search a set of possible generalisations in an attempt to find a few best hypotheses that satisfy certain requirements. Typical examples of systems which adopt this strategy are AM [Len77] DENDRAL and Meta DENDRAL [BuM78] and the approach used in the INDUCE system [DiM81]. Data driven techniques generally have the advantage of supporting incremental learning. The learning process can start not only from the specific training examples, but also from the rules which have already been discovered. The learning systems are capable of updating the existing hypotheses ....

....it is a possible explanation. The point is that XPs are associated with stereotypical situations and people in memory. An understander needs to learn the stereotypical categories that serve as useful indices for motivational explanations. This is a type of inductive category formation [Diettrich and Michalski, 1981]; however, the generalization process is constrained so that the features selected for generalization are those that are causally relevant to the explanations being indexed [Flann and Dietterich, 1989] AQUA indexes motivational XPs in memory using typical contexts in which the XPs might be ....

....this might indicate random data. ffl Another advantage is the fact that all of the training data can be used for inducing and evaluating theories. Alternative methods like cross validation or the use of some arbitrary quality criteria (e.g. the lexicographical evaluation function LEF of [Dietterich Michalski 81] need to split the training set into two parts: one will be used for induction, the other one will be used for evaluation. Splitting can be problematic for small training sets: only regularities present in both sub sets can be found and kept. Splitting of small training sets may cause an ....

Two different problems may cause irregular distributions of learning examples in the original representation space: noise and or an inadequate description language. As a remedy for the latter problem constructive induction has been introduced, e.g. in [Dietterich Michalski 81] and [Mehra et al. 89] The basic idea is to somehow transform the original representation space into a space where the learning examples exhibit (more) regularities. Usually this is done by introducing new attributes and forgetting old ones. So constructive induction is searching for an adequate ....
