Do user preferences and evaluation measures line up?

Mark Sanderson, Monica Lestari Paramita, Paul Clough, Evangelos Kanoulas
2010 Proceeding of the 33rd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '10  
It establishes that preferences and evaluation measures correlate: systems measured as better on a test collection are preferred by users.  ...  The nDCG and ERR measures were found to correlate best with user preferences compared to a selection of other well known measures.  ...  This work was co-funded by the EU FP7 project ACCURAT contract FP7-ICT-248347 and Marie Curie Fellowship FP7-PEOPLE-2009-IIF-254562.  ...

2013 Proceedings of the 7th ACM conference on Recommender systems - RecSys '13  
Catch-up TV is revolutionising viewing habits of audiences, as it provides users the opportunity to watch programs at their preferred time and place.  ...  In this work, we study the watching patterns of users of a popular Australian nationwide TV service provider and evaluate a suite of approaches for catch-up TV recommendations.  ...  We aim to deploy the resulting recommender system into the service offered by our partner broadcaster and their Web-based catch-up portal, and evaluate the performance of the recommender in a longitudinal  ...

Experimentally we evaluate our method on two large real-world datasets from Amazon.com, where we show it to outperform state-of-the-art personalized ranking measures, and also use it to visualize the high-level  ...  To uncover the complex and evolving visual factors that people consider when evaluating products, our method combines high-level visual features extracted from a deep convolutional neural network, users  ...  Thus our main goal is to learn from data how to model users' preferences toward products, and by doing so to make high-level statements about the temporal and visual dynamics at play.  ...

The model is fast and easily computable on the fly, and thus could be applied as a self-evaluation tool for editors considering becoming administrators, as a dashboard for voters to view a nominee's relevant  ...  As promotions are determined by the consensus of dozens of voters with conflicting opinions and unwritten expectations, the results highlight the degree to which consensus is truly reached.  ...  This work is supported by NSF grants IIS IIS-0325049 and IIS-0729286 and an NSF Graduate Research Fellowship.  ...

Yet, the interaction with them lacks security and privacy as it takes place in a public setting. Additionally, users have to wait in line until they can interact with the terminal.  ...  Our findings give novel insights about security relevant aspects such as where and when users interact with the mobile service before accessing the public terminal.  ...  ACKNOWLEDGEMENT We would like to thank the participants of our user study.  ...

Serial hook-ups

2009 Proceedings of the 5th Symposium on Usable Privacy and Security - SOUPS '09  
Usability measures included: task performance times, ratings on the System Usability Scale (SUS), task completion, and perceived security.  ...  We present the overall study results and identify methods that are particularly problematic for certain classes of users as well as those that are best-suited for various device configurations.  ...  This method is deceptively simple since IR is line-ofsight. Setting it up requires the user to find IR ports on both devices -not a trivial task for many -and align them.  ...

Our method has been deployed in the Microsoft Power BI product and released to millions of users.  ...  We demonstrate improvement over existing techniques in terms of overall accuracy, number of examples required, and program complexity.  ...  If so, then the first preference is to simply prefer any program in the alignment group if it directly satisfies the examples, since this program satisfies the full alignment group and the examples and  ...

In practice, this most often means an interaction between a patient and clinician who are in different sites, through the use of transmitted live sound and video images.  ...  Telepsychiatry is the delivery of healthcare and the exchange of healthcare information for purposes of providing psychiatric services across distances (Yellowlees et al, 2003).  ...  However, the views expressed are those of the authors and not necessarily those of the Programme or the Department of Health.  ...

Augmenting Bottom-up Metamodels with Predicates

Ross Gore, Saikou Diallo, Christopher Lynch, Jose Padilla
2017 Journal of Artificial Societies and Social Simulation  
There are two metamodeling approaches for ABMs: ( ) top-down and ( ) bottom-up. The top down approach enables users to decompose high-level mental models into behaviors and interactions of agents.  ...  For most users the construction of a bottom-up metamodel entails: ( ) creating an experimental design, ( ) running the simulation for all cases specified by the design, ( ) collecting the inputs and output  ...  While the BIC information criterion enables the e ectiveness of our approach to be conservatively evaluated, some users may prefer di erent measure of e ectiveness.  ...
