Binary splitting algorithm

In mathematics, binary splitting is a technique for speeding up numerical evaluation of many types of series with rational terms. In particular, it can be used to evaluate hypergeometric series at rational points. See more Given a series $${\displaystyle S(a,b)=\sum _{n=a}^{b}{\frac {p_{n}}{q_{n}}}}$$ where pn and qn are integers, the goal of binary splitting is to compute integers P(a, b) and Q(a, b) such … See more Binary splitting requires more memory than direct term-by-term summation, but is asymptotically faster since the sizes of all occurring subproducts are reduced. Additionally, whereas the most naive evaluation scheme for a rational series uses a full … See more WebFeb 6, 2024 · Given the hypothesis of a bi-modal distribution of cells for each marker, the algorithm constructs a binary tree, the nodes of which are subpopulations of cells. At each node, observed cells and markers are modeled by both a family of normal distributions and a family of bi-modal normal mixture distributions. Splitting is done according to a …

WebDec 11, 2024 · The representation of the CART model is a binary tree. This is the same binary tree from algorithms and data structures, nothing too fancy (each node can have zero, one or two child nodes). A node represents a single input variable (X) and a split point on that variable, assuming the variable is numeric. http://www.sthda.com/english/articles/35-statistical-machine-learning-essentials/141-cart-model-decision-tree-essentials/
