Randomness in Connectivity

• I haven't made a lot of use of randomness in neural models, but often use it for connectivity.
• There are built in functions for connectivity (e.g. all to all, one to all) but I usually use a connection list.
• You can build anything with connection lists so it replaces all of the others.
• When I'm engineering (with NEAL) I specify exactly.
• When I'm using other connection mechanism (like small world topologies) I just randomly select a target neuron.
• You can also randomly select both the pre and post synaptic neurons.
