Limited PMML Support for Analytic Models

 K-means

 Association rules (ARULE)

 Naïve Bayes

Support is implemented with the following new analytic procedures:

 PMML_MODEL

 EXPORT_PMML

This new feature is described in more details in the “PMML” section of the IBM SPSS In-

Database Analytics Developer's Guide.

Logistic Regression and Generalized Linear Models (GLM)

New to this release are algorithmic procedures to support GLM. These are:

 GLM

 PREDICT_GLM

Detailed information on these new procedures can be found in the “Generalized Linear

Models” section of the IBM SPSS In-Database Analytics Developer's Guide.

Netezza Lua API for Analytics

Beginning with Release 2.0, Netezza Analytics includes a variant of Lua, which enables

users to take advantage of the Netezza appliance's highly parallelized environment. Lua is

an extension programming language designed to support general procedural programming

with data description facilities. It also offers good support for object-oriented programming,

functional programming, and data-driven programming. Lua is intended to be used as a

powerful, lightweight scripting language for any program that needs one. For more informa-

tion on Netezza Lua, see the IBM Netezza Lua Developer's Guide.

Perl Adapter For User-Defined Analytic Procedures

Users can extend SQL with user-defined functions (UDXs) as well as user-defined analytic

processes (UDAPs). The UDAP concept allows a user to implement a freestanding, exe-

cutable data-processing program that runs “out of process” (that is, outside the database

system), and register it in a database. UDAPs provide several important features that are

not available with a UDX. For example, a UDX must be coded in C++ but UDAPs can be

written in a variety of languages, allowing users to capitalize on their existing programming

skills. Release 2.0 provides support for writing UDAPs in the Perl language. For more infor-

mation on UDAPs and the Perl Adapter, see the User-Defined Analytics Process Devel-

oper's Guide.

Changes to nzMatrix

nzMatrix has improved the matrix multiplication procedure (GEMM) and introduced new

random number generators in this release.
