&gt; Backpropagation itself is not biologically plausible because, among other things, real neurons can’t just stop processing the external world and wait for backpropagation to begin — if they did, we’d end up with lapses in our vision or hearing.<p>Counterpoint: Our brain works around &quot;lapses in our vision&quot; constantly. See <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Chronostasis" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Chronostasis</a> or <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Blind_spot" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Blind_spot</a>.<p>(Not saying that makes backpropagation biologically plausible, but as phrased, their argument is not convincing.)

&quot;Neuron Bursts Can Mimic Famous AI Learning Strategy&quot; is an obnoxiously ass backwards headline given that techniques used in AI, such as back propagation, are to some extent modelled on the behaviour of real neurons. AI, and neural networks in particular, are heavily influenced by the behaviour of real neurons and real brains so it&#x27;s hardly news when brains do things that &quot;mimic&quot; AI. Geez.

There is an old poem called the Psychomachia by a poet named Prudentious. <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Psychomachia" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Psychomachia</a><p>It is a fascinating poem -- it all takes place in the character&#x27;s head. The virtues and the vices battle it out, individually, but as a complete battle. It is, in my opinion, a great example of a Generated Adversarial Network.<p>The reason a lot of great art ends up representing deep mathematical truths is that art is, at its best, an act of deep observation, whether it is of oneself or the world around oneself.<p>I wouldn&#x27;t bother reading the Psychomachia -- I translated parts of it in college and I agree with C.S. Lewis that it is a more known poem than a good one. I still found its observation of the mind in parts doing battle useful for myself when I have dealt with mental illness in my life.
