In this paper we develop an asymptotic theory for estimation based on signed ranks in the ARMA model when the innovation density is symmetrical. We provide two classes of estimators and we establish their asymptotic normality with the help of the asymptotic properties for serial signed rank statistics. Finally, we compare our procedure to the one of least-squares, and we illustrate the performa...

The management of heterogeneous networks requires the capabilities to combine differing types of data and to account for events occurring on different time scales. No single network management methodology is likely to satisfy the diverse needs of today’s networks so as to maintain a desirable level of quality-of-service (QoS)–based performance. Rather, an integrated approach is needed in which ...

In this paper we consider the task of articulated 3D human pose estimation in challenging scenes with dynamic background and multiple people. Initial progress on this task has been achieved building on discriminatively trained part-based models that deliver a set of 2D body pose candidates that are then subsequently refined by reasoning in 3D [1, 4, 5]. The performance of such methods is limite...

The performance of many computer vision methods depends on the quality of the local features extracted from the images. For most methods the local features are extracted independently of the task and they remain constant through the whole process. To make features more dynamic and give models a choice in the features they can use, this work introduces a set of intermediate features referred as ...

Studies on human infants, focused on the ontogenetic origins of knowledge, have provided evidence for a small set of separable systems of core knowledge dealing with the representation of objects, number, and space. We investigated core knowledge systems from a comparative perspective, making use of the domestic chick as a model system, and filial imprinting as a key to animal mind. Here, we di...

Part-based representations have been shown to be very useful for image classification. Learning part-based models is often viewed as a two-stage problem. First, a collection of informative parts is discovered, using heuristics that promote part distinctiveness and diversity, and then classifiers are trained on the vector of part responses. In this paper we unify the two stages and learn the ima...
