Excited to see the paper fully published. It's an important milestone for training SNNs with exact gradients, replacing our earlier tricks of a "delay line augmentation" to capture temporal relationships. Delays can now be learnt alongside weights naturally. Amazing work @mbalazs98.bsky.social !
Our paper on event-based delay learning is now published! @neworderofjamie.bsky.social @drtnowotny.bsky.social
TL;DR: It’s now possible to train synaptic delays in large-scale spiking neural networks with high temporal precision—even in recurrent connections.

Excellent paper and great new project. Very interesting how the race of technology between GPU and FPGA shapes up.
Belated exciting news! First paper from my new(ish) project with the very talented Zainab Aizaz is out at ieeexplore.ieee.org/document/110.... Results from the first prototype of our fully-programmable FPGA-based SNN accelerator, showing off its stochastic rounding capabilities and speediness.

Hallucination is totally the wrong word, implying it is perceiving the world incorrectly.
But it's generating false, plausible sounding statements. Confabulation is literally the perfect word.
So, let's all please start referring to any junk that an LLM makes up as "confabulations".
