In this paper we investigate statistical language models with a variable context length. For such models the number of relevant words in a context is not xed as in conventional M gram models but depends on the context itself. We develop a measure for the quality of variable-length models and present a pruning algorithm for the creation of such models, based on this measure. Further we address t...

during spring and summer of 2010 and 2012, several surveys were conducted in different vineyards in kohgiluyeh & boyer-ahmad (southwestern iran) and kerman (southeastern iran) provinces, with the aim of isolating and identifying fungi associated with grapevine decline diseases. the samples collected comprised diseased grapevines showing yellowing, defoliation, reduced growth, wilting, intervein...

Angiogenesis produces primitive vascular networks that need pruning to yield hierarchically organized and functional vessels. Despite the critical importance of vessel pruning to vessel patterning and function, the mechanisms regulating this process are not clear. Here we show that EphrinB2, a well-known player in angiogenesis, is an essential regulator of endothelial cell death and vessel prun...

Structural neural network pruning aims to remove the redundant channels in deep convolutional networks (CNNs) by filters of less importance final output accuracy. To reduce degradation performance after pruning, many methods utilize loss with sparse regularization produce structured sparsity. In this paper, we analyze these sparsity-training-based and find that unpruned is unnecessary. Moreover...

An eecient parallel algorithm FPM(Fast Parallel Mining) for mining association rules on a shared-nothing parallel system has been proposed. It adopts the count distribution approach and has incorporated two powerful candidate pruning techniques, i.e., distributed pruning and global pruning. It has a simple communication scheme which performs only one round of message exchange in each iteration....

Discovering maximal frequent itemset is a key issue in data mining; the Apriori-like algorithms use candidate itemsets generating/testing method, but this approach is highly time-consuming. To look for an algorithm that can avoid the generating of vast volume of candidate itemsets, nor the generating of frequent pattern tree, DCIP algorithm uses data-set condensing and intersection pruning to f...

Orbits in different dispersive billiard systems, e.g. the 3 disk system, are mapped into a topological well ordered symbol plane and it is showed that forbidden and allowed orbits are separated by a monotone pruning front. The pruning front can be approximated by a sequence of finite symbolic dynamics grammars. 1 ‡ Permanent address: Phys Dep., University of Oslo, Box 1048, Blindern, N-0316 Oslo

continual bearing and production of the highest quality fruits in kiwi requires initial training and regular annual pruning. effects of three training systems including t-bar, as a common training system, modified ty (mty) and y-shape (y), and two pruning levels (60 and 80 buds per vine) was studied on yield and quality characteristics of kiwifruit ‘hayward’. experiment was carried out in a fac...

This study aims to determine the effect of corn leaf pruning on soybean growth and yield in an intercropping system. research was carried out farmers' land Simpang Village, Berbak District, Tanjung Jabung Timur Regency from July - October 2020. using a Randomized Block Design (RBD) with 5 replications. Pruning treatments based position leaves stem were : without (control/p0), 3 at near soil sur...
