Detecting The Abnormal: Machine Learning In Computer Security, Terran Lane, Carla E. Brodley Feb 1997

Detecting The Abnormal: Machine Learning In Computer Security, Terran Lane, Carla E. Brodley

Department of Electrical and Computer Engineering Technical Reports

TINOpr oblems of importance in computer security are to I) detect the presence of an intruder masquerading as the valid user and 2) detect the perpetration of abusive actions on the part of an otherwise innocuous user. In this paper we present a machine learning approach to anomaly detection, desigined to handle these two problems. Our system learns a user profile for each user account and subsequently employs it to detect anomalous behavior in that account. Based on sequences of actions (UNIX commands) of the current user's input sti:earn, the system compares each fixed-length input sequence with a historical library …

The Effects Of Protection On The Patter Of Trade: A Disaggregated Analysis (A), Jon D. Haveman, U. C. Nair, Jerry Thursby Jan 1997

The Effects Of Protection On The Patter Of Trade: A Disaggregated Analysis (A), Jon D. Haveman, U. C. Nair, Jerry Thursby

Purdue CIBER Working Papers

We analyze the effects of protection using disaggregated data. This permits analysis of distinct effects of tariffs and NTBs on trade. Our analysis indicates that tariffs tend to shift trade towards larger exporters. We find significant trade diversion caused by tariffs. In the case of NTBs, we find quantitative barriers are more likely to raise prices than are price restrictions. Quantity barriers appear to lead exporters to concentrate on higher priced varieties. We do not find much evidence to suggest that countries not targeted by an NTB gain at the expense of targeted countries. We find that NTBs tend to …


Currency Boards, Expectations And Inflation Persistence, J. A. Carlson Jan 1997

Currency Boards, Expectations And Inflation Persistence, J. A. Carlson

Purdue CIBER Working Papers

Adopting the exchange rate as a nominal anchor for monetary stabilization has proved costly in a number of countries as inflationary inertia produces severe real exchange rate appreciation. What causes inflation persistence? Complementary to existing explanation such as staggered contracts and low credibility, we note that the introduction of a new monetary rule, such as a fixed exchange rate reduces inflationary expectations immediately to the target level only if all agents understand the implications of the rule.


Cross-National Empirical Generalization Of A Supplier Selection And Usage Model For Foreign Exchange Services, D. Bowman, J. U. Farley, D. C. Schmittlein Jan 1997

Cross-National Empirical Generalization Of A Supplier Selection And Usage Model For Foreign Exchange Services, D. Bowman, J. U. Farley, D. C. Schmittlein

Purdue CIBER Working Papers

This paper tests generalizations across four countries of an industrial marketing model applied to foreign exchange services which banks sell to large corporations. The process by which customers elicit bids from the marketplace, evaluate suppliers, and award business is used in a two-step framework typical for industrial markets: (1) factors important to winning and/or retaining any business (supplier selection) in a context of multiple suppliers; and (2) factors important to growing business volume of a particular supplier (supplier usage).


Measurement Of Perceived Environmental Uncertainties: Response And Extension, K. D. Miller Jan 1997

Measurement Of Perceived Environmental Uncertainties: Response And Extension, K. D. Miller

Purdue CIBER Working Papers

Miller (1993) presented an instrument for measuring managers' perceptions of the environmental uncertainties relevant to international business. Application of this instrument by Werner, Brouthers, and Brouthers (1996), led them to suggest an alternative measurement instrument. This study applies confirmatory factor analysis to examine the reliability and discriminant validity of these alternatives PEU scales.


Economic Lessons Of The Kobe Earthquake, G. Horwich Jan 1997

Economic Lessons Of The Kobe Earthquake, G. Horwich

Purdue CIBER Working Papers

The earthquake that struck the Japanese port city of Kobe on January 17, 1995, was the most severe quake ever to strike a modern urban area. It has become the most studied, analyzed, and discussed natural disaster in history. What I propose to add to this dialogue is an economist's overview of what he saw in Kobe 19 months after the event and what he learned during the ensuing 6 months.


Procompetitive Market Access, Marie Thursby, Kala Krisna, S. Roy Jan 1997

Procompetitive Market Access, Marie Thursby, Kala Krisna, S. Roy

Purdue CIBER Working Papers

The view that US businesses are being unfairly hurt by barriers to access in foreign markets has raised demands for market access requirements (MARs) from within US industry and government alike. We show that, contrary to the prevailing wisdom of the recent literature, MARs can be implemented in a procompetitive manner. The basic idea is that the requirement must be implemented in a way that provides the right incentives for increasing aggregate output or lowering prices.


Rational Speculators And Exchange Rate Volatility, J. A. Carlson, C. L. Olser Jan 1997

Rational Speculators And Exchange Rate Volatility, J. A. Carlson, C. L. Olser

Purdue CIBER Working Papers

This paper suggests a structural connection between rational speculative activity and exchange rate volatility. We note that, when Friedman originally claimed that rational speculators must smooth exchange rate, he excluded interest rate differentials form his interpretation of speculator behavior. If interest rates matter, rational speculators could sometimes violate Friedman's description, and buy a currency whose value is relatively high or sell a currency whose value is low.
