In this chapter, bounds on the average depth and the average weighted depth of decision trees are considered. Similar problems are studied in search theory [1], coding theory [77], design and...doi:10.1007/978-3-642-22661-8_2I. ChikalovSpringer Berlin Heidelberg...

In essence, si,t is a Bernoullian random variable of parameter pi,t, which we compactly denote \({s}_{i,t} \sim \,\text{Bernoulli}\,({p}_{i,t})\). The complexity of this model arises from the fact that the value of the parameter pi,t is not known a priori, as it ...
The significant aspect in evaluating the time complexity of inference in gradient-boosted trees lies in the fact thatτdoes not depend on the dataset sizen. Generally, the computational cost of making predictions with gradient-boosted trees correlates with the number of trees in the ensemble, typic...
So let's say your code consists of reading n integers and then iterating through all pairs of them. Your time consumption should be something like n + n^2, for reading and going through the pairs, respectively. The notion that time complexity gives us is that if your code is too slow...
28 - Layering presets adds more believable complexity Layering up several interconnected scatters in this way is the key to creating fast believable environments that are easy to art direct. The final scene was created using only the techniques discussed in this tutorial to add background trees, ...
Cubic time algorithms of amalgamating gene trees and building evolutionary scenarios We developed a deterministic solving algorithm with a low degree polynomial (typically cubic) time complexity with respect to the size of input data. We ... Lyubetsky,VA,Rubanov,... - 《Biology Direct》 被引量...

Tree springtime blooms, for example, may be cultural signifiers of spring, tourist attractants, or early stages of tree fruit production, but can also have implications for human health in the form of allergenic pollen output. The Correspondence highlights the complexity of urban environments, the...
1 Introduction Rendering outdoor scenes with a great number of trees or plants cannot be accom- plished in real-time with present graphic hardware. Many current interactive applica- tions such as flight simulators, virtual reality environments or computer games happen in outdoor scenes and one ...
