| Human Brain(Biological Neuron Network) | Computers(Artificial Neuron Network) |
|---|---|
| The human brain works asynchronously | Computers(ANN) work synchronously. |
| Biological Neurons compute slowly (several ms per computation) | Artificial Neurons compute fast (<1 nanosecond per computation) |
| The brain represents information in a distributed way because neurons are unreliable and could die any time. | In computer programs every bit has to function as intended otherwise these programs would crash. |
| Our brain changes their connectivity over time to represents new information and requirements imposed on us. | The connectivity between the electronic components in a computer never change unless we replace its components. |
| Biological neural networks have complicated topologies. | ANNs are often in a tree structure. |
| Researchers are still to find out how the brain actually learns. | ANNs use Gradient Descent for learning. |
