Excitation energies and clcctromagnetic transition strengths in even-even 96-108Mo muclei have been dcscribed systcmatically by using the proton-neutron interacting boson model (IBM-2). It appears that the properties oflow-lying levels in these isotopes, for which the comparison between experimcnt and theory is possible, can be satisfac-torily described by the IBM-2 model, provided proper account is taken of the presence at low energy of statcs having amixed-symmetry character. It seems possible to identify, in each isotope, a few states having such a character, the lowestones being either 2+2 or 2+3 levels. It is found that these nuclei are in the transition from U(5) to SU(3).

Although amazing progress has been made in ma- chine learning to achieve high generalization accuracy and ef- ficiency, there is still very limited work on deriving meaning- ful decision-making actions from the resulting models. How- ever, in many applications such as advertisement, recommen- dation systems, social networks, customer relationship man- agement, and clinical prediction, the users need not only ac- curate prediction, but also suggestions on actions to achieve a desirable goal （e.g., high ads hit rates） or avert an unde- sirable predicted result （e.g., clinical deterioration）. Existing works for extracting such actionability are few and limited to simple models such as a decision tree. The dilemma is that those models with high accuracy are often more complex and harder to extract actionability from. In this paper, we propose an effective method to extract ac- tionable knowledge from additive tree models （ATMs）, one of the most widely used and best off-the-shelf classifiers. We rigorously formulate the optimal actionable planning （OAP） problem for a given ATM, which is to extract an action- able plan for a given input so that it can achieve a desirable output while maximizing the net profit. Based on a state space graph formulation, we first propose an optimal heuris- tic search method which intends to find an optimal solution. Then, we also present a sub-optimal heuristic search with an admissible and consistent heuristic function which can re- markably improve the efficiency of the algorithm. Our exper- imental results demonstrate the effectiveness and efficiency of the proposed algorithms on several real datasets in the application domain of personal credit and banking.

协同联盟中组织模型的研究

计算机科学 2003年第2期30卷 113-117页

作者：路鹏张小蕾陶先平吕建计算机软件新技术国家重点实验室南京大学计算机软件研究所南京210093

The architecture of a coordination system can naturally be viewed as an organized society of individuals (i. e. ,as a computational organization). For this reason,we believe organizational model should play a central role in the coordination systems including coordination association. To this end, the concepts of role models, architecture styles ,and coordination laws are increasingly being used to specify and design coordination systems. However,this is not th full picture. In this paper we develop three organizational concepts - organizational role model,organizational structure,and organizational rules - that we believe are necessary for the complete specification of computational organisations of coordination association.
