PageRank is a graph algorithm that assigns importance to nodes based on their links, and is named after its inventor - Larry Page. The algorithm is frequently applied to web graphs to calculate an importance of each node [url] in the graph.

PageRank is an algorithm to assign importance to nodes in linked data base, and is named after its inventor - Larry Page. The algorithm is frequently used on the web - to calculate an importance of each node [url] in the database.

The algorithm is simulating a random-surfer model. The random surfer starts from a random node in the graph, and can chose to use an out edge from this vertex at probability α, or to jump into a random node at probability 1-α. The score of each node is the probability of the random surfer to be at this node at some point in time.

The algorithm is patented, and IP rights belong to Stanford University.

Computing Page Rank on GPU using Pull-based Traversal

I have a CUDA kernel that computes the Page Ranks using a Push-based traversal. I am trying to convert it to one that follows a Pull-based traversal strategy but I am always getting wrong results. What am I doing wrong? (Assume for simplicity that…

The Google PageRank Algorithm

I am going through the PageRank algorithm. In the book Elements of Statistical Learning in chapter Unsupervised Learning the follwing statement is given: The PageRank algorithm considers a webpage to be important if many other webpages point to…

Is PageRank a graph-based unsupervised learning algorithm?

From what I have read. PageRank is good example of Spectral clustering. If this is correct then PageRank can be dubbed as Unsupervised Learning on Graphs. Can anyone justify if PageRank is Unsupervised Learning.

How is google giving every page a rank out of 10?

according to wikipedia:PageRank A probability is expressed as a numeric value between 0 and 1. A 0.5 probability is commonly expressed as a "50% chance" of something happening. Hence, a PageRank of 0.5 means there is a 50% chance that a…
