Predictive Models in Value-Based Software Engineering

Ye Yang, Professor - Institute of Software, Chinese Academy of Sciences (ISCAS)

ABSTRACT:  Value-based software engineering requires the integration of value considerations into the full range of existing and emerging software engineering principles and practices. Software predictive models have become the underlying enabler to optimize development processes and support value associated forecasting needs. Most existing defect prediction models and cost estimation models build their predictive power against empirical data of historical projects, i.e., learning knowledge from historical project and then transferring these knowledge to future development. In practice, empirical data collected from different projects or organizations over long period of time usually exhibit different distributional patterns, or in a machine learning point of view, data shift happens. Due to emerging development paradigms and dynamic nature of software processes, data shift problems become one of the open challenges and place great limitations and uncertainties in the applicability, accuracy, and robustness of traditional software predictive models. In this talk, I will introduce our work on expanding the arsenal of software predictive models to address a variety of prediction needs, and present a solution to address data shift problems to cope with data dynamism and improve model applicability and accuracy. 

BIOGRAPHY:  Ye Yang is a Professor at the Institute of Software, Chinese Academy of Sciences (ISCAS). She received her Ph.D. in Computer Science from the University of Southern California in 2006. Her research lies in the area of empirical software engineering including software cost estimation, defect prediction, and software process modeling methods, as well as promoting the development and transferring of research prototype toolkits in software industry. Her research has been funded by a number of Chinese national research programs including the Ministry of Education, NSFC, 863/973, HeGaoJi, CAS Innovation Promotion Program, as well as industry collaborators.  

She has co-edited two conference proceedings, published over 60 research papers, and some of them won Best Research Paper Awards at International Conference on Predictive Models in Software Engineering, Evaluation of Novel Approaches to Software Engineering, Hawaii International Conference on System Sciences, and Conference of the International Society of Parametric Analysts. She has served as Program co-Chairs for ICSP 2010, Steering Committee member for PROMISE 2012-2013, and Program Committee member for a number of international conferences including ASE, ICSE SEIP, ESEM, APSEC, etc. She is a member of the editorial board of Journal of Cost Analysis and Parametric and Journal of Software (Chinese).
