A typical example of RDD-centric functional programming is the following Scala program that computes the frequencies of all words occurring in a set of text files and prints the most common ones. Each map , flatMap (a variant of map ) and reduceByKey takes an anonymous function that performs a simple operation on a single data item (or a pair ...
Word2vec is a technique in natural language processing (NLP) for obtaining vector representations of words. These vectors capture information about the meaning of the word based on the surrounding words.
Function spaces appear in various areas of mathematics: In set theory, the set of functions from X to Y may be denoted {X → Y} or Y X. As a special case, the power set of a set X may be identified with the set of all functions from X to {0, 1}, denoted 2 X. The set of bijections from X to Y is denoted .
The Ziegler–Nichols tuning method is a heuristic method of tuning a PID controller.It was developed by John G. Ziegler and Nathaniel B. Nichols.It is performed by setting the I (integral) and D (derivative) gains to zero.
Platelet-derived growth factor (PDGF) is one among numerous growth factors that regulate cell growth and division.In particular, PDGF plays a significant role in blood vessel formation, the growth of blood vessels from already-existing blood vessel tissue, mitogenesis, i.e. proliferation, of mesenchymal cells such as fibroblasts, osteoblasts, tenocytes, vascular smooth muscle cells and ...
Peritoneal dialysis (PD) is a type of dialysis that uses the peritoneum in a person's abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood. [ 1 ] [ 2 ] It is used to remove excess fluid, correct electrolyte problems , and remove toxins in those with kidney failure . [ 3 ]
The Logical Framework Approach takes the form of a four-by-four project table, often referred to as a "Logframe". The rows represent types of events that take place as a project is implemented: Activities, Outputs, Purpose and Goal (from bottom to top on the left hand side — see EC web site under external links).
