Overtting is a widely observed pathology of induction algorithms. For induction algorithms that build decision trees, pruning is a common approach to correct overtting. Most common pruning techniques , do not account for one potentially important factor | multiple comparisons. Multiple comparisons occur whenever an induction algorithm examines several candidate models and selects the one that b...

In this paper we introduce a well-motivated abstract pruning criterion for LVCSR decoders based on the anticipated recombination of HMM state alignment paths. We show that several heuristical pruning methods common in dynamic network decoders are approximations of this pruning criterion. The abstract criterion is too complex to be applied directly in an efficient manner, so we derive approximat...

Developmental axon pruning is essential for normal brain wiring in vertebrates and invertebrates. How axon pruning occurs in vivo is not well understood. In a mosaic loss-of-function screen, we found that Bsk, the Drosophila JNK, is required for axon pruning of mushroom body γ neurons, but not their dendrites. By combining in vivo genetics, biochemistry, and high-resolution microscopy, we demon...

In a three year study, IOOderate and severe root pruning just before planting was compared to no root pruning, on two size classes of seedlings (smaller and larger than average). Seedlings were bar planted in holes the full depth of the planting bar blade. For the smaller seedlings, survival was 1.0 percentage point higher for moderate pruning and 5.6 points lower for severe pruning compared to...

the high quality and quantity seed production in old saxual shrubs are essential for regeneration and sustainable development of saxual forests in desert areas. the objective of this study was to determine the effects of different pruning height on saxual seed production. the study was carried out in an obviously wilted saxual forest located in ashkezar desert in yazd in 1994. the experiment wa...

In this paper, games with chance nodes are analysed. The evaluation of these game trees uses the expectiminimax algorithm. We present pruning techniques involving random effects. The gamma-pruning aims at increasing the efficiency of expectiminimax (analogously to alpha-beta pruning and the classical minimax). Some interesting properties of these games are shown: for instance, a game without dr...

|Neural network pruning methods on the level of individual network parameters (e.g. connection weights) can improve generalization, as is shown in this empirical study. However, an open problem in the pruning methods known today (OBD, OBS, autoprune, epsiprune) is the selection of the number of parameters to be removed in each pruning step (pruning strength). This work presents a pruning method...

Pruning is an unavoidable necessity of virtually all arboreal fruit crops. In the tropics and subtropics, pruning of mango (Mangifera indica L.) is particularly important due to its tendency for frequent flushes, especially in humid tropics. Commercial orchards must maintain control of both tree size and orchard productivity in order to remain productive. Tip, formation, and severe pruning can ...

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...
