We study the problem where a decision maker uses a linear classifier over attribute values (e.g., age, income, etc.) to classify agents into classes (e.g., creditworthy or not). Sometimes the attribute values are altered and/or hidden by agents to ob

Online auction markets play increasingly important roles for resource allocations in distributed systems. This paper builds upon a market-based framework presented by Guo et al. (Guo, Z., G. J. Koehler, A. B. Whinston. 2007. A market-based optimizati

This paper gives a quantum algorithm for global optimization. The heart of such approaches employ Grover's database search (1996; Phys Rev Lett 79(23):4709---4712, 1997a; 79(2):325---328, 1997b). Chi and Kim (1998) show that when the phases of the ge

It is known that a knapsack inequality can be reduced to one having the same solutions but with “minimal” integer coefficients. Although this procedure is not practical because an exponential amount of work may be required to find such minimal eq

Many countries limit the influence of foreign entertainment products, such as music, film, and television programs, to protect their domestic cultural industry. Commonly observed policy tools include quotas, tariffs, and subsidies. However, advances

We develop a methodology for automatically analyzing text to aid in discriminating firms that encounter catastrophic financial events. The dictionaries we create from Management Discussion and Analysis Sections (MD&A) of 10-Ks discriminate fraudulent

We study the problem of finding a global optimal solution to discrete optimization problems using a heuristic based on quantum computing methods. (Knowledge of quantum computing ideas is not necessary to read this paper.) We focus on a successful qua

With the rapid development of information technology, massive data collection is relatively easier and cheaper than ever before. Thus, the efficient and safe exchange of information becomes the renewed focus of database management as a pervasive issu

This paper provides a methodology for detecting management fraud using basic financial data. The methodology is based on support vector machines. An important aspect therein is a kernel that increases the power of the learning machine by allowing an

In a new learning paradigm called Induction over Strategic Agents, the principal anticipates possible alteration of attributes by agents wishing to achieve a positive classification. In many cases, agents are constrained on how an attribute can be mo
