I’m a postdoc @Imperial, working with @neural-reckoning.org. I’m passionate about brain‑inspired neural networks, focusing on delay learning in RNNs (spiking/rate) and lightweight attention mechanisms.https://bsky.app/profile/pengfei-sun.bsky.socialhttps://bsky.app/profile/pengfei-sun.bsky.social/post/3m5k2aedqgc2rWith my great advisors and colleagues, @achterbrain.bsky.social @zhe @danakarca.bsky.social @neural-reckoning.org, we show that if heterogeneous axonal delays (imprecise) can capture the essential temporal structure of a task, spiking networks do not need precise synaptic weights to perform well.

Your feedback is welcome—let us know how it performs in your models!
