Competitive analysis of financial games
Proceedings., 33rd Annual Symposium on Foundations of Computer Science, 1992In the unidirectional conversion problem an on-line player is given the task of converting dollars to yen over some period of time. Each day, a new exchange rate is announced and the player must decide how many dollars to convert. His goal is to minimize the competitive ratio. defined as sup/sub E/ (P/sub OPT/(E)/P/sub X/E) where E ranges over exchange

An Analysis of IPTV Competition Model
2010 10th IEEE/IPSJ International Symposium on Applications and the Internet, 2010The diffusion patterns and its speed of IPTV are so different country by country. We started to analyse some markets; Japan, Korea, Taiwan, and the U.S.A, by using extended five-force model of Michel Porter. And found condition for IPTV diffusion. At the same time we found that it can be some industrial structures instead of fully integrated (IPTV, ISP,

Principal Components Analysis Competitive Learning
Neural Computation, 2004We present a new neural model that extends the classical competitive learning by performing a principal components analysis (PCA) at each neuron. This model represents an improvement with respect to known local PCA methods, because it is not needed to present the entire data set to the network on each computing step. This allows a fast execution while

Digital Piracy: A Competitive Analysis
Marketing Science, 2008In recent years, the issue of copyright protection for intellectual properties such as computer software, music CDs, and videos has become increasingly important. It is often claimed that illegal copying of intellectual property costs companies billions of dollars in lost revenues and reduces firms' incentives to innovate.
