Question 1

What is the difference between topography and topology of neural networks?

Answer 1

Topography.

A topographic map is the ordered projection of a sensory surface, like the retina or the skin, or an effector system, like the musculature, to one or more structures of the central nervous system. Topographic maps can be found in all sensory systems and in many motor systems.

Topology.

Network Topology refers to layout of a network. How different nodes in a network are connected to each other and how they communicate is determined by the network’s topology. Network Topology refers to the layout of a network and how different nodes in a network are connected to each other and how they communicate

Question 2

Make the adjacency matrix for this network

Answer 2

Question 3

What is the difference between neural plasticity and learning?

Answer 3

Plasticity refers to the ability of synaptic weights to change. Learning is the change in synaptic weights so as to better perform a specific task.
