Overview

Jack Gallant's lab demonstrates reconstructing movie trailer clips a subject watched from fMRI brain activity, using regression models trained on hours of viewing data. The video shows the original clip beside the reconstruction.

This is a much cooler example [VIDEO] If I'm understanding the description correctly, they are just training it to recognize what the image is closest to and taking an slice of a youtube video that most closely matches it. I imagine if they used a more efficient method or trained it more, they could do way better. It seems like most of the data to build an accurate picture of what they are seeing is already there.

I imagine the best case outcome would look something like Jack Gallant's 2011 work on visual mind reading, where they trained a model on brain activity watching hundreds of hours of YouTube and then attempted to reconstruct a view of video not in the training set by correlating the new brain activity with frames from the input... Sorry I'm not explaining very clearly but there's a YouTube video of the result naturally :) [VIDEO] Learned about this from Mary Lou Jepsens 2013 TED talk, what a throwback [LINK]

I mean in 2011, they were already able to do some basic reconstruction: see [VIDEO] I could imagine improvements since then,especially with advances in image networks.
