Supervised and unsupervised discretization of continuous features
- in A. Prieditis & S. Russell, eds, Machine Learning: Proceedings of the Twelfth International Conference
, 1995
"... Many supervised machine learning algorithms require a discrete feature space. In this paper, we review previous work on continuous feature discretization, identify de n-ing characteristics of the methods, and conduct an empirical evaluation of several methods. We compare binning, an unsupervised dis ..."

-Bayes slightly outperformed C4.5 on average. We also show that in some cases, the performance of the C4.5 induction algorithm signi cantly improved if features were discretized in advance � in our experiments, the performance never signi cantly degraded, an interesting phenomenon considering the fact that C4
Intrinsic and extrinsic motivations: Classic definitions and new directions.
- Contemporary Educational Psychology,
, 2000
"... Intrinsic and extrinsic types of motivation have been widely studied, and the distinction between them has shed important light on both developmental and educational practices. In this review we revisit the classic definitions of intrinsic and extrinsic motivation in light of contemporary research ..."

motivation in those around them. Most theories of motivation reflect these concerns by viewing motivation as a unitary phenomenon, one that varies from very little motivation to act to a great deal of it. Yet, even brief reflection suggests that motivation is hardly a unitary phenomenon. People have not only
Rumor Routing Algorithm for Sensor Networks
, 2002
"... Advances in micro-sensor and radio technology will enable small but smart sensors to be deployed for a wide range of environmental monitoring applications. In order to constrain communication overhead, dense sensor networks call for new and highly efficient methods for distributing queries to nodes ..."

reliability. It's intended for contexts in which geographic routing criteria are not applicable because a coordinate system is not available or the phenomenon of interest is not geographically correlated.
The Generation Effect: Delineation of a Phenomenon
- Journal of Experimental Psychology: Human Learning and Memory
, 1978
"... Five experiments are reported comparing memory for words that were generated by the subjects themselves with the same words when they were simply presented to be read. In all cases, performance in the generate condition was superior to that in the read condition. This held for measures of cued and u ..."

is to report a set of simple experiments that establish the existence of a robust and interesting phenomenon of memory. This phenomenon, called the gen-eration effect, is robust in that it manifests itself across a variety of testing proce-dures, encoding rules, and other situational changes. It is interesting
Citizens as sensors: the world of volunteered geography.”
- GeoJournal
, 2007
"... Abstract In recent months there has been an explosion of interest in using the Web to create, assemble, and disseminate geographic information provided voluntarily by individuals. Sites such as Wikimapia and OpenStreetMap are empowering citizens to create a global patchwork of geographic informatio ..."

I review this phenomenon, and examine associated issues: what drives people to do this, how accurate are the results, will they threaten individual privacy, and how can

Post Script: The paper provides insights into some of the ramifications of personal financial planning arousing sufficient passion, interest and partisanship for members to define themselves to some extent as a
Economic theory of choice and the preference reversal phenomenon.
- American Economic Review,
, 1979
"... A body of data and theory has been developing within psychology which should be of interest to economists. Taken at face value the data are simply inconsistent with preference theory and have broad implications about research priorities within economics. The inconsistency is deeper than the mere la ..."

The Average Distance in a Random Graph with Given Expected Degrees
"... Random graph theory is used to examine the “small-world phenomenon”– any two strangers are connected through a short chain of mutual acquaintances. We will show that for certain families of random graphs with given expected degrees, the average distance is almost surely of order log n / log ˜ d whe ..."

Team mental model: Construct or metaphor
- Journal of Management
, 1994
"... There has been a recent resurgence of interest in group cognition in the field of organizational science. However, despite the apparent enthusiasm for the notion of the group mind in some modern guise, important conceptual work is needed to examine the concept critically. We attempt to do this in ou ..."

Recently, there seems to be a resurgence of interest in this notion as writers and researchers in such fields as business policy and strategy (e.g., Bonham,
Selfish Routing and the Price of Anarchy
- MATHEMATICAL PROGRAMMING SOCIETY NEWSLETTER
, 2007

The outcome of selfish routing is generally inefficient, in that it fails to optimize natural objective functions. The price of anarchy is a quantitative measure of this in ..."
