September 21, 2022, 7AM-8:30AM PST: Dr. Alexander G. Ororbia
"Brain-Inspired Computing: Going Beyond Backpropagation of Errors" ...
Videoconference at: https://singularitynet.zoom.us/my/benbot ...

Description: "In this talk, I will discuss an emerging and promising
sub-domain of statistical learning research known as brain-inspired
computing, which focuses on developing artificial neural models and
credit assignment algorithms that draw inspiration from what is
currently known about the operation of biological neurons and human
brains in general. Starting from the popular backpropagation of errors
(backprop) procedure used to train modern-day deep neural networks, I
will discuss its various biological criticisms and practical
shortcomings to then turn towards backpropagation-free methodology,
including processes such as recirculation, local representation
alignment, contrastive Hebbian learning, wake-sleep, and predictive
processing."

Hi Ben!

This sounds interesting, I'd like to watch it!

Was it recorded?

Best regards,

Patrick

Hey Patrick, here is a link to the recording: https://youtu.be/IeRTyWzlvq8

It was a very lively conversation, and I'll be sure to reach out if we have the chance to bring Alex back for some follow-up conversation.

Talk soon!

Hi Haley,

I get “ Video unavailable: This video has been removed by the uploader”.

Any chance that could be fixed. That presentation was excellent and one I’ve wanted to share with several other folks recently.

Thanks.

-Luke

Hey Luke, thanks for the catch; we are in the process of moving the recordings to a dedicated OpenCog channel.
