Using ReLU instead of sigmoid is a significant departure with regards to how closely it models actual neurons.
Using non fully connected layers is as well. Our brains likely aren’t fully connected, but the connections that matter are made stronger through living life and learning.
If you squint, it’s kind of like training a dense series of linear layers, but that’s not what we’re doing anymore (for the better)
Comparing NNs to organic brains is an apples to oranges comparison, is what I’m saying.

- samus 3y agoI agree that the biggest difference is the missing ability of an artificial neuronal network to adapt.
- ben_w 3y agoLack of adaption is mainly a feature, we choose not to train them in real-time and instead make available fixed models with repeatable behaviour. We could, if we wanted to, update the model weights continuously in response to feedback. I think the biggest difference is that they need far more examples than we need, to learn anything.
