Information visualization has recently been formulated as an information retrieval problem, where the goal is to find similar data points based on the visualized nonlinear projection, and the visualization is optimized to maximize a compromise between (smoothed) precision and recall. We turn the visualization into a generative modeling task where a simple user model parameterized by the data co...

Multitrial free and serial recall tasks differ both in recall instruction and in presentation order across trials. Waugh (1961) compared these paradigms with an intermediate condition: free recall with constant presentation order. She concluded that differences between free and serial recall were due only to recall instructions, and not to presentation order. The present study reevaluated the r...

INTRODUCTION Poor recall during investigations of foodborne outbreaks may lead to misclassifications in exposure ascertainment. We conducted a simulation study to assess the frequency and determinants of recall errors. METHODS Lunch visitors in a cafeteria using exclusively cashless payment reported their consumption of 13 food servings available daily in the three preceding weeks using a sel...

We investigate the impact of the precision/recall trade-off of information extraction on the performance of an offline corpus-based question answering (QA) system. One of our findings is that, because of the robust final answer selection mechanism of the QA system, recall is more important. We show that the recall of the extraction component can be improved using syntactic parsing instead of mo...

Young children's production and recall of information presented at varying levels of action and verbal labels was compared on a computer versus a felt board. Forty children, equally distributed by Grades Preschool and Kindergarten, were randomly assigned to a computer or felt board condition. Within each condition, the same 24 objects (6 sets of 4 objects) were presented with or without action ...

A health warning was presented to 89 female and 19 male students aged 17-36 years via three modalities or channels of communication: a 'talking head' (video), an audiotape recording (audio) or a printed transcript (print). The verbal content of the message was identical in all three conditions. Participants' free recall, cued recall (recognition) and global recall of the message were then measu...

In this controlled experiment we examined whether there are content effects in verbal short-term memory and working memory for verbal stimuli. Thirty-seven participants completed forward and backward digit and letter recall tasks, which were constructed to control for distance effects between stimuli. A maximum-likelihood mixed-effects logistic regression revealed main effects of direction of r...

PURPOSE Remembering medical treatment information may be particularly taxing for older cancer patients, but to our knowledge this ability has never been assessed in this specific age group only. Our purpose in this study was to investigate older cancer patients' recall of information after patient education preceding chemotherapy. DESIGN AND METHODS We constructed a recall questionnaire consi...

Games with imperfect information are an interesting and important class of games. They include most card games (e.g., bridge and poker) as well as many economic and political models. Here we investigate algorithms for finding the simplest form of a solution (a pure-strategy equilibrium point) to imperfect information games expressed in their extensive (game tree) form. We introduce to the artif...
