[CONF] Apache Lucene Mahout: Matrix Needs (page created)

Matrix Needs (MAHOUT) created by Grant Ingersoll
   http://cwiki.apache.org/confluence/display/MAHOUT/Matrix+Needs

Content:
---------------------------------------------------------------------

h1. Intro

We need some basic Matrix operations to start, and will definitely need more as we go.


h2. Background

See [http://mail-archives.apache.org/mod_mbox/lucene-mahout-dev/200802.mbox/browser]

h2. Needs

We will more than likely need all the basic Matrix operations, plus some more advanced ones:

* Addition, Subtraction, Multiplication, Transpose, Inverse, Scaling


For ideas like PageRank/TextRank, iterative approaches that, essentially, calculate eigenvectors are also useful.



h2. Ideas

Use HBase (BigTable) in Hadoop
