Harmony networks have been proposed as a means by which connectionist models can perform symbolic computation. Indeed, proponents claim that a harmony network can be built that constructs parse trees for strings in a context free language. This paper shows that harmony networks do not work in the following sense: they construct many outputs that are not valid parse trees. In order to show that ...

The multidimensional data association methods were developed to establish the relation between plots and tracks especially in dense target situations. However, even these advanced multidimensional data association methods lack in situations of unresolved measurement. Specifically, in real dense target situations being of most interest the phenomena of unresolvedplots happens quite often due to ...

This paper proposes a procedure for comparison of target tracking filters in cluttered environment, using simulated experiments. Important simulation issues, including track generation and retention across simulation runs and true track definition are discussed. False track discrimination is identified as an important target tracking filter performance measure. This measure has two components; ...

Consent ought to be required to withhold treatment that is in a patient's best interests to receive. Do not resuscitate (DNR) orders are examples of best interests assessments at the end of life. Such assessments represent value judgments that cannot be validly ascertained without patient input. If patient input results in that patient dissenting to the DNR order then individual physicians are ...

Phase field and diffuse interface are popular methods for the modeling and simulations of evolving interfaces. They do not track the interface explicitly, and are insensitive to topological events. In some areas of applications, detecting and controlling topological change may be important. In this talk, we discuss some recent works with current and former colleagues at Penn State (C. Liu, R. R...

This paper gives an overview of the INEX 2010 Ad Hoc Track. The main goals of the Ad Hoc Track were three-fold. The first goal was to study focused retrieval under resource restricted conditions such as a small screen mobile device or a document summary on a hitlist. This leads to variants of the focused retrieval tasks that address the impact of result length/reading effort, thinking of focuse...
