- *Abstract
-
- *Background
- Artificial neural networks (ANNs) attempt to replicate the remarkable efficiency of the biological brain for performing cognitive tasks, such as learning, pattern recognition and classification. The two main computational units of the artificial neuron are weighted summation of inputs followed by a threshold. The implementation of large scale ANNs on general purpose computers requires significant computational capability and consumes energy that is orders of magnitude larger than a biological brain. These inefficiencies are due to the significant mismatch between the functionality of a biological neuron and the CMOS devices, which are better suited for Boolean logic.
