The method of induction requires two cases to be proved. The first case, called the base case (or, sometimes, the basis ), proves that the property holds for the number 0. ... Complete induction is equivalent to ordinary mathematical induction as described above, in the sense that a proof by one method can be transformed into a proof by the other. Suppose there is a proof of P ( n) by complete induction.

Method And System For Extraction And Normalization Of Relationships Via Ontology Induction
Methods for developing an ontology of pharmacogenomics (PGx) relationships starting from a lexicon of key pharmacogenomic entities and a syntactic parse is described. The syntactic structure of PGx statements is used to systematically extract commonly occurring relationships and to map them to a common schema. In an embodiment, extracted relationships have a 70-87.7% precision and involve not only key PGx entities such as genes, drugs, and phenotypes (e.g., VKORCl, warfarin, clotting disorder), but also critical entities that are frequently modified by these key entities (e.g., VKORCl polymorphism, warfarin response, clotting disorder treatment).

Local Causal and Markov Blanket Induction Method for Causal Discovery and Feature Selection from Data
In many areas, recent developments have generated very large datasets from which it is desired to extract meaningful relationships between the dataset elements. However, to date, the finding of such relationships using prior art methods has proved extremely difficult especially in the biomedical arts. Methods for local causal learning and Markov blanket discovery are important recent developments in pattern recognition and applied statistics, primarily because they offer a principled solution to the variable / feature selection problem and give insight about local causal structure. The present invention provides a generative method for learning local causal structure around target variables of interest in the form of direct causes / effects and Markov blankets applicable to very large datasets and relatively small samples. The method is readily applicable to real-world data, and the selected feature sets can be used for causal discovery and classification. The generative method GLL-PC can be instantiated in many ways, giving rise to novel method variants. In general, the inventive method transforms a dataset with many variables into either a minimal reduced dataset where all variables are needed for optimal prediction of the response variable or a dataset where all variables are direct causes and direct effects of the response variable. The power of the invention and significant advantages over the prior art were empirically demonstrated with datasets from a diversity of application domains (biology, medicine, economics, ecology, digit recognition, text categorization, and computational biology) and data generated by Bayesian networks.

A low velocity air burst munition and launcher system allows the user to program the munition to detonate in the air at a specified range from the muzzle. The system further allows the munition to detonate upon impact or self-destruct if the target is missed. The system allows the user to program and reset the munition multiple times, and allows the user to perform this operation at night in cold weather conditions. The system requires the user to manually input the range into a fuze programming device prior to projectile launch. The fuze programming device is capable of direct interface with electronic range determining devices. The system employs electrical contacts in the chamber of the munition launcher barrel and on the projectile body to complete the circuit used for programming. Furthermore, this system is capable of integrating a magnetic induction method of programming.

Lightweight rule induction
InactiveUS6523020B1Data processing applicationsDigital data processing detailsData setAdaptive weighting
A lightweight rule induction method is described that generates compact Disjunctive Normal Form (DNF) rules. Each class may have an equal number of unweighted rules. A new example is classified by applying all rules and assigning the example to the class with the most satisfied rules. The induction method attempts to minimize the training error with no pruning. An overall design is specified by setting limits on the size and number of rules. During training, cases are adaptively weighted using a simple cumulative error method. The induction method is nearly linear in time relative to an increase in the number of induced rules or the number of cases. Experimental results on large benchmark datasets demonstrate that predictive performance can rival the best reported results in the literature.
