The broad context of this study is the investigation of the nature of computation in recurrent networks (RNs). The current study has two parts. The first is to show that a RN can solve a problem that we take to be of interest (a counting task), and the second is to use the solution as a platform for developing a more general understanding of RNs as computational mechanisms. We begin by presenti...

Kudos to The Virus Hunters

To The Editor: On 6th October the Nobel Assembly at Karolinska Institute, Stockholm, Sweden announced The Nobel Prize in Physiology or Medicine for 2008, and virologists all over the world had a lot to cheer about. Three “virus hunters” who worked with two different viruses brought honour to virology. Harald zur Hausen for his discovery of "human papilloma viruses (HPV) causing cervical cancer”...

Inquiring Rock Hunters

The Inquiring Rock Hunters project is an example of Citizen Inquiry. Adult citizens designed and ran their own investigations in geology, through the online platform called nQuire, while collaborating with scientists. Analysis of the investigations shows patterns of collaboration and mentoring between novice, intermediate and expert geologists, however further work is needed to create a self-su...

Generalization of Elman Networks

The Vapnik Chervonenkis dimension of Elman networks is innnite. Here, we nd constructions leading to lower bounds for the fat shattering dimension that are linear resp. of order log 2 in the input length even in the case of limited weights and inputs. Since niteness of this magnitude is equivalent to learnability, there is no a priori guarantee for the generalization capability of Elman networks.
