methods of improving tree crops quality (increasing of branching) in the orchards' nursery
the quality of plant stocks in the nursery has proven to be a key determinant factor in precocity of fruit bearing period and the size of tree crops. the quality of these trees is related to growth strength of the applied rootstock, the tendency of the cultivars to produce branches, the growth season's weather conditions as well as the efficiency of different treatments stimulating branchi...
متن کاملBoosting Using Branching Programs
It is known that decision tree learning can be viewed as a form of boosting. Given a weak learning hypothesis one can show that the training error of a decision tree declines as |T| where |T| is the size of the decision tree and b is a constant determined by the weak learning hypothesis. Here we consider the case of decision DAGs—decision trees in which a given node can be shared by different b...

15 صفحه اولMatrix Analytic Methods in Branching processes
We examine the question of solving the extinction probability of a particular class of continuous-time multi-type branching processes, named Markovian binary trees (MBT). The extinction probability is the minimal nonnegative solution of a xed point equation that turns out to be quadratic, which makes its resolution particularly clear. We analyze rst two linear algorithms to compute the extincti...
متن کاملPoisson representations of branching Markov and measure-valued branching processes
Representations of measure-valued processes in terms of countable systems of particles are constructed for models with spatially varying birth and death rates. Each particle has a location and a “level,” but unlike earlier constructions, the levels change with time. In fact, death of a particle occurs only when the level of the particle hits infinity. For each time t the joint distribution of l...
