sional Runs Statistic. (Under the direction of DANA QUADE.) Friedman and Rafsky have generalized the runs statistic presented by Wald and Wolfowitz for testing the homogeneity of two populations to include the comparison of multivariate populations. Their multi-dimensional runs statistic can be defined as the number of links between observations from different populations, where observations ma...

Most westerners would probably think that the roots of democracy lie in Ancient Athens, when the city state established the process by which all citizens, well, men of Athenian parentage, had an equal say in the decisions of the state. This model of ‘equally shared’ consensus decision making has wobbled, been ignored and often forgotten in intervening history but the concept has endured. But wa...

In this notebook, we describe the automatic retrieval runs from NEC Laboratories America (NECLA) for the Text REtrieval Conference (TREC) 2012 Medical Records track. Our approach is based on a combination of UMLS medical concept detection and a set of simple retrieval models. Our best run, sennamed2, has achieved the best inferred average precision (infAP) score on 5 of the 47 test topics, and ...

We describe the participation of the SocialSensor team in the Placing Task of MediaEval 2014. We submitted three runs based on tag information for the full test set, using extensions over an existing language modelling approach, and two runs (one based on the full test set and the other on the 25,500 subset) based on visual content, using geospatial clustering and supervised-learning. Our best ...

Macquarie University’s contribution to the BioASQ challenge (Task 5b Phase B) focused on the use of query-based extractive summarisation techniques for the generation of the ideal answers. Four runs were submitted, with approaches ranging from a trivial system that selected the first n snippets, to the use of deep learning approaches under a regression framework. Our experiments and the ROUGE r...

The role of sensory-motor components in language processing is a central topic in cognitive neuroscience. Recent studies showed that the processing of action words recruits cortical motor regions involved in the planning and execution of the described actions. However, it remains unclear to what extent the abstract versus concrete nature of the described motion modulates the activation of premo...

Lastly, I wish to illustrate and to stress the necessity of assessing goodness of fit by making use of several tests and not relying on only one or two such tests. Referring to Table 1, the xz test and the Runs test indicate that model 3 is a good fit, whereas the curved Rankits plot, the slow convergence, the non-linearity at the minimum sum of squares and the wide range of the coefficients of...

A common method to localize defects is to compare the coverage of passing and failing program runs: A method executed only in failing runs, for instance, is likely to point to the defect. Some failures, though, come to be only through a specific sequence of method calls, such as multiple deallocation of the same resource. Such sequences can be collected from arbitrary Java programs at low cost;...
