Getting closer to the dream! A network that uses unlabelled images to boost performance when labels are scarce (new SOTA), and it's no worse than ResNet when labels are plentiful. Also: Unsupervised net + just a linear on top outperforms original AlexNet! arxiv.org/abs/1905.09272

Calling all my scientist friends that routinely hand-write equations which eventually go into papers. HOLY SHIT THIS EXISTS

Two #cosyne19 posters elucidating early visual system hallmark properties, w/ @SamOcko @Jack_W_Lindsey & @SuryaGanguli: 1) Why are receptive fields concentric in the retina and oriented in primary visual cortex? We address this question with an anatomically constrained deep CNN.

the Twitter and Pandora apps should trade names the one you open and it makes pretty sounds should be called "Twitter" the one that opening it unleashes a thousand horrors until you feel like you are being flayed alive - that one should be called "Pandora"

Adaptive feature detection from differential processing in parallel retinal pathways

To transmit information efficiently in a changing environment, the retina adapts to visual contrast by adjusting its gain, latency and mean response. Additionally, the temporal frequency selectivity,...

1/ Why are there so many *types* of ganglion cells transmitting visual information from the retina to the brain? In this joint work with @SamOcko, Jack Lindsey and @SuryaGanguli, we tried to answer this question through the lens of efficient coding: biorxiv.org/content/early/20…
