Analysis of Chi-square Automatic Interaction Detection (CHAID) and Classification and Regression Tree (CRT) for Classification of Corn Production

Yuliana Susanti, Etik Zukhronah, Hasih Pratiwi, Respatiwulan, H. Sri Sulistijowati
2017 Journal of Physics, Conference Series  
For that reason, corn production needs to be improved by considering the influencing factors. CHAID and CRT are methods of data mining which can be used to classify the influencing variables.  ...  Rules of splitting According to Breiman et al. [4] , a regression tree is constructed through splitting of data groups and a series of binary splitting until the last node is yielded.  ...  The classification tree diagram follows top-down rule; the tree diagram is constructed from parents to subgroups split from the parents based on criterion of the number of independent variable categories  ...

The relationship between Tree Adjoining Grammars and Head Grammars

D. J. Weir, K. Vijay-Shanker, A. K. Joshi
1986 Proceedings of the 24th annual meeting on Association for Computational Linguistics -  
67 We examine the relationship between the two grammatical formalisms: Tree Adjoining Grammars and Head Grammars. We briefly investigate the weak equivalence of the two formalisms.  ...  We associate with each auxiliary tree a set of productions such that each tree generated from this elementary tree with frontier wiXw2 has. an associated derivation in the MHG, using these productions,  ...  For each production in the MHG we have an auxiliary tree. A production in an MHG can use one of the three operations: C1, C2, and W. Correspondingly we have three types of trees, shown below.  ...

Manipulation of fruit set and stylar-end fruit split in 'Nova' mandarin hybrid

G.H. Barry, J.P. Bower
1997 Scientia Horticulturae  
Calcium nitrate application during flowering reduced fruit split, while girdling using a Spanish girdling tool increased fruit set dramatically.  ...  Nova' mandarin hybrid is prone to stylar-end fruit splitting when produced in solid, isolated blocks. In addition, self-incompatibility and weak parthenocarpy result in poor fruit set.  ...  The long-term effects of girdling on tree longevity are still unknown, and whether only one or two seasons of girdling are required to force young 'Nova' trees into production and then allowing them to  ...
