New preprint from @DeWeeseLab!

TLDR: experiments show neurons in primary visual cortex are tuned for lower spatial frequencies earlier in development. We show the theory of sparse coding is sufficient to account for this phenomenon.

A hamster has been trading cryptocurrencies in a cage rigged to automatically buy and sell tokens since June by running on a wheel & strolling through tunnels: it's currently outperforming the S&P 500, its portfolio being up ~24% on Friday [read more: https://t.co/ZM9P2MvgCE]

Come check out our project with @s_y_chung at @neur_reps! TLDR: Unsupervised learning of representations using retinal waves (real spontaneous neural activity data collected by @MiahPitcher!) points towards a biologically plausible means of learning object recognition.

A lot of Machine Learning (ML) I learned during my Ph.D. was from youtube. I didn't have a guide to do this effectively and thus here it is:

@tootyawbatriz The obstacle is the models in question take static images as their inputs like a CNN would, and performs inference on each image independent of other images in the batch. We’re working on a version that can process images in a continuous stream.

@tootyawbatriz @DeWeeseLab Re: sound, we aren’t modeling auditory cortex, but later work might consider the interplay between auditory and visual cortex during development.

@tootyawbatriz @DeWeeseLab The upshot here is that these results as they stand can tell us about how V1 develops w/r/t the spatial statistics of natural scenes, without considering the temporal statistics, which natural movies would give us.

@elaineshen_ this week, my code didn't work

[DeWeese Lab @DeWeeseLab]

Congrats to lab member Juliana Chase for the well-deserved shoutout!

[DeWeese Lab @DeWeeseLab]

Excited to share this new work on swift equilibration! Congrats to all the authors! https://t.co/J45gQe9p05

There’s never a legitimate reason to use ‘obvious’ in a research paper or presentation.

@alienelf I jumped into his mentions once bc he made a comment that the nazis were the ‘real fascists’ implying that anyone opposing fascism today is delusional. like the fascists don’t use the platform that he’s in charge of 🤡

@elaineshen_ Can't decide which fit goes harder tbh

[DeWeese Lab @DeWeeseLab]

We're excited to share our recent work on the structure of neural network loss surfaces! Congrats to @charles_irl, Jamie Simon, @li_geralde, and @negative_result.
