http://ttoy.net Specialists in AI, modeling, and learning Mon, 28 Mar 2005 18:10:24 +0000 http://backend.userland.com/rss092 en TTOY.net and Galaxy Global announce a new effort to use advanced data mining methods to develop the next generation of software defect detectors. Mike Chapman, Chief Information Officer at Galaxy Global, commented today that “Current methods, in widespread use, don’t take into account the business context of the data miners. ... http://ttoy.net/news/ttoy-galaxy-global-to-build-business-aware-defect-predictors/ TToy and Galaxy Global team together to build business-aware defect detectors. Working with USC, UHawaii, and JPL, TTOY find better ways to perform software cost estimation: [1,2]. NASA’s Jet Propulsion Laboratory and TTOY sign agreements to research software cost estimation. http://ttoy.net/site/home/whats-hot/ Delta estimation uses changes to old projects to estimate new projects. Delta estimation assumes that new costs can be extrapolated from old projects. There exists attributes in some data sets where this assumption does not hold. We define here an automatic method to find which attributes can be safely used ... http://ttoy.net/news/safer-simpler-software-cost-analysis/ TTOY’s technologies are based on decades of work in modelling and learning using AI, OO,logic programming, data mining, and Unix scripting. With these tools, we strive to simplify human-in-the-loop theory formation and revision. The goal is to augment what humans do best with what computers do best. Humans, we believe, are ... http://ttoy.net/profile/technologies/ Cost estimation is important in software development for controlling and planning software risks and schedule. Good estimation models, such as COCOMO, can avoid insuffcient resources being allocated to a project. In this study, we find that COCOMO’s estimated can be improved via WRAPPER- a feature subset selection method developed by ... http://ttoy.net/news/feature-subject-selection-can-improve-software-cost-estimation/ Experience has shown that the most expensive bad decisions are made earliest in the software lifecycle. For example, it a project’s costs are under-estimated then developers will be forced into many quality-threatening cost-cutting measures as the project commences. One reason for poor cost estimation is that, all too often, NASA’s ... http://ttoy.net/news/ttoy-jet-propulsion-laboratory-software-costing-research/ TTOY’s owner and chief scientist is Dr. Tim Menzies. Dr. Menzies has been working on advanced software engineering techniques since 1986. He is the author of nearly 150 research papers. For two years, was the Software Engineering Research Chair at NASA’s Independent Verification and Validation (IV&V) Facility. Currently, he is on ... http://ttoy.net/profile/people/ These terms govern your use of this web site. If you do not agree with these terms, do not use this web site.
