# Personalized Pagerank with Accuracy Assurance Algorithm

A Personalized Pagerank with Accuracy Assurance Algorithm is a Personalized PageRank Algorithm that is based on a relevance measure.

**Context:**- It was first developed and implemented by Fujiwara et al. (2012).

**Example(s):**- ...

- QUOTE: The heart of our solution is to compute single node relevance accurately in non-iterative manner based on sparse matrix representation, and to compute top-k/highly relevant nodes exactly by pruning unnecessary relevance computations based on upper/lower relevance estimations. Our experiments show that our approach is up to seven orders of magnitude faster than the existing alternatives.
