Patent number: 8997841Abstract: A flat heat exchanger plate typically used in a bulk material heat exchanger having an improved construction which increases heat transfer and service period by reducing bulk material accumulation. The flat heat exchanger plate is designed to operate under a negative internal pressure to eliminate depressions or dimples that are typically formed into the sides of these types of heat exchanger coils during the manufacture process. The dimples are created to reinforce the heat exchanger plate from positive internal pressures that other wise would cause the heat exchanger plate to bow due to internal positive pressures. With the removal of the depressions or dimples the tendency for bulk material to accumulate to the exterior surface of the plate is reduced, thereby increasing the service period of the plate and heat transfer. The flat heat exchanger plate tapers from wide to narrow along the direction of flow of bulk material across the plate to further reduce accumulation of bulk material.Type: GrantFiled: August 18, 2006Date of Patent: April 7, 2015Inventor: Peter Dawson

Patent number: 8655918Abstract: A process of transforming data residing in databases, such as relational databases, into forms suitable as input to data analysis tools, such as predictive modeling tools includes the steps of defining a business process problem to be solved and identifying data requirements. For example, the business process problem may relate to predicting a customer's propensity to make purchases in the future or a store's requirements for inventory in the future. In the process, a computer implemented method is used for automatically transforming data for data analysis such as predictive modeling. Database metadata that describe database tables, their interrelationships, dimensional information, fact tables and measures are accessed. A mining transformation profile is created to encapsulate aggregations and transformation on data stored in relational databases in order to convert the data to forms suitable for predictive mining tools.Type: GrantFiled: October 26, 2007Date of Patent: February 18, 2014Assignee: International Business Machines CorporationInventors: Upendra Chitnis, Christoph Lingenfelder, Edwin Peter Dawson Pednault

Patent number: 8392153Abstract: The present invention generally relates to computer databases and, more particularly, to data mining and knowledge discovery. The invention specifically relates to a method for constructing segmentation-based predictive models, such as decision-tree classifiers, wherein data records are partitioned into a plurality of segments and separate predictive models are constructed for each segment. The present invention contemplates a computerized method for automatically building segmentation-based predictive models that substantially improves upon the modeling capabilities of decision trees and related technologies, and that automatically produces models that are competitive with, if not better than, those produced by data analysts and applied statisticians using traditional, labor-intensive statistical techniques. The invention achieves these properties by performing segmentation and multivariate statistical modeling within each segment simultaneously.Type: GrantFiled: September 4, 2008Date of Patent: March 5, 2013Assignee: International Business Machines CorporationInventors: Edwin Peter Dawson Pednault, Ramesh Natarajan

Patent number: 7561158Abstract: Feature importance information available in a predictive model with correlation information among the variables is presented to facilitate more flexible choices of actions by business managers. The displayed feature importance information combines feature importance information available in a predictive model with correlational information among the variables. The displayed feature importance information may be presented as a network structure among the variables as a graph, and regression coefficients of the variables indicated on the corresponding nodes in the graph. To generate the display, a regression engine is called on a set of training data that outputs importance measures for the explanatory variables for predicting the target variable. A graphical model structural learning module is called that outputs a graph on the explanatory variables of the above regression problem representing the correlational structure among them.Type: GrantFiled: January 11, 2006Date of Patent: July 14, 2009Assignee: International Business Machines CorporationInventors: Naoki Abe, Edwin Peter Dawson Pednault, Fateh Ali Tipu
