Supervised training approach using spiking neural networks

One of the basic aspects of some neural networks is their attempt to approximate as much as possible their biological counterparts. The goal is to achieve a simple and robust network, easy to understand and able of simulating the human brain at a computational level. Recently a third generation of neural networks (NN) [1], called Spiking Neural Networks(SNN) was appeared. This new kind of networks use the time of a electrical pulse, or spike, to encode the information. In the first and second generation of NN analog values are used in the communication between neurons.

Intervention for organizational innovation: a case study

This article is intended to report an intervention in a SME of the IT sector, aiming at an organizational change process towards a greater proactivity of employees. The presentation of the case includes the diagnosis, intervention, and the beginning of the implementation of innovation projects, based on an adapted model of third generation large-group organizational change methods. In addition to the steps followed, small-world analysis techniques were used, with the intention of determining the existing communication networks; also, a content analysis of collected success stories was made, in order to suggest strong points for a future organizational culture. The results clarified the desirable characteristics of an intervention method with large groups, adapted to Portuguese companies, and effective in organizational innovation project design. The analysis of the success stories helped to determine the strengths of an orientation for the future, while the use of measures of small-world networks allowed us to analyze the existing informal organization. Although this study does not include the completion of the projects, due to difficulties in the company, it can provide a solid basis for application in future interventions.
