Facing the Ugly Face

The Good, the Bad, and the Ugly Face Challenge Problem

The Good, the Bad, & the Ugly Face Challenge Problem was created to encourage the development of algorithms that are robust to recognition across changes that occur in still frontal faces. The Good, the Bad, & the Ugly consists of three partitions. The Good partition contains pairs of images that are considered easy to recognize. The base verification rate (VR) is 0.98 at a false accept rate (F...

Facing facts: neuronal mechanisms of face perception.

The face is one of the most important stimuli carrying social meaning. Thanks to the fast analysis of faces, we are able to judge physical attractiveness and features of their owners' personality, intentions, and mood. From one's facial expression we can gain information about danger present in the environment. It is obvious that the ability to process efficiently one's face is crucial for surv...

Are the Ugly Truths Not Ugly Enough?

In recent years there has been an increase in the number of papers, many of which have been published in high profile journals, that address real environmental or ecological problems, but with flawed, subjective, and frequently hyperbolic arguments. I identify two such examples from the US Gulf of Mexico, linked by their focus on fisheries resources as the cause de jour, to illustrate the probl...

The Good, the Bad, and the Ugly, But How Ugly Is Ugly?

When monitoring a system wrt. a property defined in a temporal logic such as LTL, a major concern is to settle with an adequate interpretation of observable system events; that is, models of temporal logic formulae are usually infinite words of events, whereas at runtime only finite but incrementally expanding prefixes are available. In this work, we review LTL-derived logics for finite traces ...
