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 ..."

Bias in Absolute Magnitude Determination from

by Michael Feast , 2008
"... The general methods for dealing with bias in the analysis of astronomical (or other) data were set out by Eddington (1913, 1940, see also Dyson 1926). Athough these are quite straightforward, the current literature shows that there is ..."

Absolute identification by relative judgment

by Neil Stewart, Gordon D. A. Brown, Nick Chater - Psychological Review , 2005
"... In unidimensional absolute identification tasks, participants identify stimuli that vary along a single dimension. Performance is surprisingly poor compared with discrimination of the same stimuli. Existing models assume that identification is achieved using long-term representations of absolute mag ..."

-term representations of absolute magnitudes, the RJM accounts for (a) information transmission limits, (b) bowed serial position effects, and (c) sequential effects, where responses are biased toward immediately preceding stimuli but away from more distant stimuli (assimilation and contrast).

Absolute and Relative Range Bias Detection Capabilities

by Husson Van
"... Abstract: The computed orbit is the final yardstick in accessing ILRS data quality. The absolute accuracy of orbit determination depends ultimately on the quality and quantity of data, but is a trailing (not leading) indicator of ‘true ’ network performance. In order to successfully monitor improvem ..."

and will be characterized in terms of absolute and relative range bias detection capabilities. Some new bias detection techniques will be explored and evaluated. Below in Table 1 are a list of bias detection techniques and their capabilities. System characterization [Pearlman 1984] is a methodology for conducting on

TOPICS IN MITIGATING RADAR BIAS

by Demetrios Serakos, John E. Gray, Hazim Youssef , 810
"... In this paper, we investigate two topics related to mitigating the effect of radar bias in ballistic missile tracking applications. We determine the absolute bias between two radars in polar coordinates when their relative bias is given in rectangular coordinates. Using this result, we then obtain t ..."

Octave bias in an absolute pitch identification task

by Giulia Boschetti, Valter Prpic, Matteo De Tommaso, Mauro Murgia, Tiziano Agostini
"... Octave errors are common within musicians, even among absolute pitch possessors. Overall, evidence shows pitch class and octave to be perceived in a different way, even if they are highly connected. We investigated whether pitch class perception, in an absolute pitch identification task, can be infl ..."

Evaluating the accuracy of implicit feedback from clicks and query reformulations in web search

but biased. While this makes the interpretation of clicks as absolute relevance judgments difficult, we show that relative preferences derived from clicks are reasonably accurate on average. We find that such relative preferences are accurate not only between results from an individual query, but across

Explaining the enigmatic anchoring effect: Mechanisms of selective accessibility

by Fritz Strack , Thomas Mussweuer , Jens Fiedler , Bettina Forster , Tory Hannover , Roland Higgins , Norbert Neumann , Sabine Schwarz , Lioba Stepper , Werner Werth , Wippich - Journal of Personality & Social Psychology , 1997
"... Results of 3 studies support the notion that anchoring is a special case of semantic priming; specifically, information that is activated to solve a comparative anchoring task will subsequently be more accessible when participants make absolute judgments. By using the logic of priming research, in ..."

RA-2 ABSOLUTE RANGE CALIBRATION

by unknown authors
"... The EnviSat altimeter, RA-2, is intended to continue an uninterrupted series of measurements of sea-level and ice-sheet elevation started by ERS-1 in 1991. To fully exploit these measurements, an absolute reference in the time series, and a distinction between instrumental artifacts and significant ..."

Annealing structural bias in multilingual weighted grammar induction

by Noah A. Smith, Jason Eisner - In Proc. ACL , 2006
"... We first show how a structural locality bias can improve the accuracy of state-of-the-art dependency grammar induction models trained by EM from unannotated examples (Klein and Manning, 2004). Next, by annealing the free parameter that controls this bias, we achieve further improvements. We then des ..."
