What’s New in SAS Enterprise Miner 12.1
Overview
SAS Enterprise Miner
12.1 is the version of SAS Enterprise Miner that supersedes SAS Enterprise
Miner 7.1M1, released in December 2011. The updated version numbering
is a result of synchronizing analytical content among SAS data mining
software releases. SAS Enterprise Miner 12.1 provides improvements
and enhancements to the product’s core user interface, as well
as updates to the SAS Enterprise Miner Credit Scoring nodes, the SAS
Enterprise Miner Application nodes, the Rapid Predictive Modeler (RPM)
SAS Enterprise Miner add-on to SAS Enterprise Guide, and the SAS Enterprise
Miner High Performance Data Mining nodes.
SAS Enterprise Miner Core
-
Several important and common SAS
Enterprise Miner project properties have been promoted from macro
variables that were deployed via SAS code or project start code to
property selections that can be defined via the Enterprise Miner GUI
properties panel.
-
The SAS Enterprise Miner client
can now be opened directly into a specific project or diagram, or
from the most recent project and diagram.
-
The %AA_MODEL_REGISTER macro has
been added to enable users to directly register models that were developed
in SAS code into the SAS Metadata Server. Once in SAS Metadata Server,
the common model data can be accessed by SAS products such as SAS
Model Manager, SAS Enterprise Guide, and SAS Data Integration Studio.
-
The %AA_MODEL_EVAL macro has been
added in order to compute lift and Receiver Operating Characteristic-type
measures on any data set that contains probabilities and events. The
%AA_MODEL_EVAL macro uses a two-stage approximation algorithm to calculate
the model performance measures.
-
Batch code from the SAS Enterprise
Miner client can be used more easily with input tables of different
names and locations. The SAS Enterprise Miner 12.1 batch code now
integrates project start code that you can use to define libraries
and options.
-
The SAS Enterprise Miner SAS Code
node for version 12.1 contains enhanced support for score code that
contains SAS Procedure steps.
-
PMML scoring for the Decision Tree,
Regression, Neural Network, and Clustering nodes has been promoted
to production status. New experimental functions have been introduced
for general regression and scorecards in the SAS Enterprise Miner
12.1 release.
SAS Enterprise Miner Credit Scoring
-
The Interactive Grouping node user
interface has been redesigned to provide improved usability, performance,
and computational scalability.
-
The Interactive Grouping node has
added a new
Calculated variable role.
-
The Scorecard node features an
output variable that counts the number of adverse characteristics,
and users can select named input variables for adverse characteristic
reporting.
-
The Scorecard node now processes
indeterminate outcome values.
SAS Enterprise Miner Applications
-
The Gradient Boosting node now
provides users with the capability to disable the H statistic calculation,
resulting in improved run-time performance.
-
The Incremental Response node has
been promoted from experimental to production status.
-
The Time Series Data Mining nodes
have been promoted from experimental to production status. The production
Time Series Data Mining nodes have been redesigned to provide greater
ease of use as well as improved performance and scalability. It is
no longer necessary to precede Time Series Data Mining nodes with
a Time Series Data Preparation node. Time series data can now be processed
with or without a numeric TimeID variable. Time Series Data Mining
now supports sequence data. Season and Trend information is now extracted
and included in Time Series Data Mining results..
-
The Decision Tree output displays
have been enhanced to display variable precision values in the split
branches and nodes. This change improves the usability of the decision
tree tool when mining with extremely large and extremely small values.
Rapid Predictive Modeler (RPM)
-
The neural network functions in
the SAS Enterprise Miner Rapid Predictive Modeler (RPM) add-on for
SAS Enterprise Guide have been revised. The new neural network functions
provide a simplified architecture that is appropriate for business
problems. The updated changes also improve the run-time performance
of the RPM tool.
Support for High Performance Data Mining
SAS is developing a
key set of statistical and data mining tasks that execute on a dedicated
high performance appliance. SAS High Performance (HP) software distributes
data, memory, and computations over a grid of systems that produces
dramatic improvements in large data scalability and run times. Enterprise
Miner 12.1 uses the SAS High Performance system for building predictive
models.
-
All SAS Enterprise Miner High Performance
data mining procedures have been enhanced with new features. The HPFOREST
and HP4SCORE procedures have been promoted from experimental to production
status. For more information about SAS High Performance Data Mining
procedures, see the SAS Enterprise Miner documentation page at
http://support.sas.com/documentation/onlinedoc/miner/
.
-
The score code generation macros
have been deprecated, in favor of CODE statements on the relevant
HP data mining procedures. The High Performance Impute node now supports
Winsorized and Trimmed data calculations.
-
A High Performance data mining
Data Validation node has been added. The new High Performance Data
Validation node provides users with the ability to assign data rows
into training or validation partitions when training models for generalization.
-
A High Performance Forest node
has been added to facilitate modeling of highly nonlinear data.
-
The High Performance Neural node
has been enhanced with new architecture and generalization options.
-
All High Performance data mining
model nodes support missing values in class variables as a distinct
level. This technique improves both model accuracy and model deployment.
-
All High Performance data mining
model nodes now report both training and validation data set fit statistics,
as well as lift and Receiver Operating Characteristic (ROC) values.
-
The set of High Performance data
mining nodes can now be connected to more of the traditional SAS Enterprise
Miner nodes.
-
SAS Enterprise Miner High Performance
procedures and data mining nodes have been enhanced with support for
multi-byte international data sources.
