QuiltMaker
|
|
GUI-based Application |
QuiltMaker is a visual software tool that quantifies association strengths hidden in transaction data. A key use is to provide “next most likely to buy” product information to sales representatives, allowing them to rapidly identify cross-selling opportunities. These association matrices, built from past transactions, are colored according to their value on user-selected attributes (hence the customer-coined name of “quilts”). QuiltMaker can also sort the rows and columns and re-color cells to identify strong product correlations. Products grouped into families can be imported so that individual products can be compared against other product families.

GROPE and Associated Optimization Algorithms

|
|
C Library
Java Library |
GROPE (Global Rd Optimization when Probes are Expensive) is a highly-efficient algorithm for global optimization that employs all known results to minimize the number of probes required. It is ideal for exploring functions with multiple modes, nonlinear or rough surfaces, a moderate number of dimensions, and an expensive evaluation function -- such as those arising from complex computer simulations. Unlike local search algorithms, it can find the overall global best, even if the surface has extreme changes and multiple local minima. GROPE also estimates the chance of improving one’s result with further probes, which is useful for planning experiments and knowing when to stop. This library also includes RandomSearch and GridSearch and a Conjugent Gradient Search (Powell’s Algorithm). The routines are in “advisor” rather than driver mode, to facilitate use with large and complex simulations. |

Texas Two Step

|
|
GUI-based Application
C library
Java library |
Texas Two Step is a proprietary decision tree algorithm that can select splits by looking one or two steps ahead, rather than merely one as with other tree algorithms. This usually leads to a more accurate decision model. The product induces models, selects variables, visualizes the tree, reports on training and evaluation errors and structures, handles categorical and real inputs and outputs, and can export the models created in PMML for further use by other commercial data mining tools. |

Nearest Neighbor

|
|
GUI-based Application
C library
Java library |
Nearest Neighbor is a graphical software tool that builds predictive models, using a consensus of k training cases that are most similar (are nearest neighbors) to the evaluation cases selected. The program employs Principle Components dimension reduction to display the results as an interactive scatterplot. A key feature is its automated discovery of the best combination of dimensions to employ in calculating nearness – the most important issue for such case-based algorithms. Estimation model results may be exported through PMML for use in other data mining tools. |

ERI Entity Extraction Editor (E4)

|
|
GUI-based Application |
E4 enables an analyst to correct the links and entity definitions induced by commercial entity extraction tools. Errors in extraction are unfortunately numerous – since “meaning” is often extremely difficult to automatically extract from text – but such errors can have deadly effect on downstream automated analysis. E4 can be used to clean up the links induced for high-value documents, making them much more useful for subsequent automated pattern discovery.
The tool allows one to move, delete, and merge links that have been identified, and write new XML output file matching that produced by commercial tools (though now corrected). The modified files can be saved with a browse-able audit trail as XML or text, which can then be used to identify incorrect classifications. E4 also enables the user to visualize the model structure, graphically lay out the model, and export or print the graph image. |
