Accurately interpreting clickthrough data as implicit feedback

by Thorsten Joachims, Laura Granka, Bing Pan, Helene Hembrooke, Geri Gay - In Proceedings of SIGIR , 2005
"... This paper examines the reliability of implicit feedback generated from clickthrough data in WWW search. Analyzing the users ’ decision process using eyetracking and comparing implicit feedback against manual relevance judgments, we conclude that clicks are informative but biased. While this makes t ..."

Corporate Financing and Investment Decisions when Firms Have Information that Investors Do Not Have

by Stewart C. Myers, Nicholas S. Majluf , 1984
"... This paper considers a firm that must issue common stock to raise cash to undertake a valuable investment opportunity. Management is assumed to know more about the firm’s value than potential investors. Investors interpret the firm’s actions rationally. An. equilibrium mode1 of the issue-invest deci ..."

The lexical nature of syntactic ambiguity resolution

by Maryellen C Macdonald, Neal J Pearlmutter, Mark S Seidenberg - Psychological Review , 1994
"... Ambiguity resolution is a central problem in language comprehension. Lexical and syntactic ambiguities are standardly assumed to involve different types of knowledge representations and be resolved by different mechanisms. An alternative account is provided in which both types of ambiguity derive fr ..."

from aspects of lexical representation and are resolved by the same processing mechanisms. Reinterpreting syntactic ambiguity resolution as a form of lexical ambiguity resolution obviates the need for special parsing principles to account for syntactic interpretation preferences, reconciles a number

What is a hidden Markov model?

by Sean R. Eddy , 2004
"... Often, problems in biological sequence analysis are just a matter of putting the right label on each residue. In gene identification, we want to label nucleotides as exons, introns, or intergenic sequence. In sequence alignment, we want to associate residues in a query sequence with ho-mologous resi ..."

splice site consenses, codon bias, exon/intron length preferences, and open reading frame analysis all in one scoring system. How should all those parameters be set? How should different kinds of information be weighted? A second issue is being able to interpret results probabilistically. Finding a best

Monopolistic competition and optimum product diversity. The American Economic Review,

by Avinash K Dixit , Joseph E Stiglitz , Harold Hotelling , Nicholas Stern , Kelvin Lancaster , Stiglitz , 1977
"... The basic issue concerning production in welfare economics is whether a market solution will yield the socially optimum kinds and quantities of commodities. It is well known that problems can arise for three broad reasons: distributive justice; external effects; and scale economies. This paper is c ..."

These lead to results involving transport costs or correlations among commodities or securities, and are hard to interpret in general terms. We therefore take a direct route, noting that the convexity of indifference surfaces of a conventional utility function defined over the quantities of all potential

Preference and Belief: Ambiguity and Competence in Choice under Uncertainty

by Chip Heath, Amos Tversky - JOURNAL OF RISK AND UNCERTAINTY , 1991
"... We investigate the relation between judgments of probability and preferences between bets. A series of experiments provides support for the competence hypothesis that people prefer betting on their own judgment over an equiprobable chance event when they consider themselves knowledgeable, but not o ..."

CP-nets: A Tool for Representing and Reasoning with Conditional Ceteris Paribus Preference Statements

by Craig Boutilier, Ronen I. Brafman, Carmel Domshlak, Holger H. Hoos, David Poole - JOURNAL OF ARTIFICIAL INTELLIGENCE RESEARCH , 2004
"... Information about user preferences plays a key role in automated decision making. In many domains it is desirable to assess such preferences in a qualitative rather than quantitative way. In this paper, we propose a qualitative graphical representation of preferences that reflects conditional dep ..."

dependence and independence of preference statements under a ceteris paribus (all else being equal) interpretation. Such a representation is often compact and arguably quite natural in many circumstances. We provide a formal semantics for this model, and describe how the structure of the network can

"Coherent Arbitrariness": Stable Demand Curves without Stable Preferences

by Dan Ariely, George Loewenstein, Drazen Prelec - JOURNAL OF ECONOMICS, FEBRUARY 2003
"... In six experiments, we show that initial valuations of familiar products and simple hedonic experiences are strongly influenced by arbitrary "anchors " (sometimes derived from a person's social security number). Because subsequent valuations are also coherent with respect to salient d ..."

differences in perceived quality or quantity of these products and experiences, the entire pattern of valuations can easily create an illusion of order, as if it is being generated by stable underlying preferences. The experiments show that this combination of coherent arbitrariness: (1) cannot be interpreted

Homo Oeconomicus 28(3): 265–296 • (2011) www.accedoverlag.d e The Revealed-Preference Interpretation of Payoffs in Game Theory

by Aki Lehtinen
"... Abstract There are two different ways of interpreting the idea that payoffs in games are revealed preferences. One could argue, first, that choices define payoffs in the sense that preferences and choices are conceptually tied to each other, and secondly, that there is an experimental procedure that ..."

Developments in the Measurement of Subjective Well-Being
