The current generation of non-modular neural network classifiers is unable to cope with classification problems which have a wide range of overlap among classes. This is due to the high coupling among the networks' hidden nodes. We propose the Cooperative Modular Neural Network (CMNN) architecture, which deals with different levels of overlap in different modules. The modules share their information and cooperate in taking a global classification decision through voting. Moreover, special modules are dedicated to resolve high overlaps in the input-space. The performance of the new model outperforms that of the nonmodular alternative when when applied to ten famous benchmark classification problems.
Improving laser range data acquisition speed is important for many robotic applications such as mapping and localization. One approach to reducing acquisition time is to acquire laser range data through a dynamically ...

In this paper, we present an improved image registration algorithm based on the virtual circles features. Virtual circles are extracted efficiently by finding the local maxima in the distance transform of the edge maps. Virtual circles are grouped into collinear set to which a line is fitted to determine the direction. The radii of the virtual circles in the group as well as the direction of the fitted line are used in the registration algorithm. The Hausdorff fraction is also used as a similarity measure to determine the optimal transformation. This algorithm can find large translation, rotation, and scale differences between two images. Further more, it has linear complexity in terms of the number of virtual circles extracted.

Cognitive Work Analysis (CWA) is gaining momentum for analyzing complex socio-technical systems but it does not yet have the specific tools and techniques that allow it to address teamwork explicitly enough to provide good guidance on how to support teams. This paper focuses on expansion of control task analysis (ConTA), the second phase of CWA, to understand the collaborative decision making of a surgical team during Cesarean section surgery.
It has been accepted that multiple classifier systems provide a platform for not only performance improvement, but more efficient and robust pattern classification systems. A variety of combining methods have been pro...
