Spiking Neural Network and unsupervised learning

Finally, SpikeNET was also able to learn in an unsupervised manner. The animation below shows learning of orientation from a collection of natural images [6].

This work was later extended by Tim Masquelier and Simon Thorpe which were able to recognize objects based on similar principles [7]. The video below shows unsupervised learning of visual categories (faces and motorcycles).

The publication section contains all the references about SpikeNET.
