    I’m actually very pro exploring the possibility that it does something like bp, and wrote 2016 essay as such — but nonetheless I re-tweet this, since it is still totally open and just a kind of “best current guess”, as was belief prop message passing circa 10 years agohttps://twitter.com/pfau/status/1105443964423938049 …

    In 100 years, we'll look back on theories of "how the brain does backpropagation" the way we look at the luminiferous aether now.

        The thing is, I don't think anything in neuroscience actually changed to discredit belief prop in the brain and give more credit to backprop in the brain. Both theories are too underconstrained at the moment to be falsified. Just one technique became more trendy in ML.

        And you know, the theory of aether was a necessary stepping stone in the development of our understanding of light. It was valuable at the time even if it was later abandoned.
