Dimensionality reduction may be the wrong approach to understanding neural representations. Our new paper shows that across human visual cortex, dimensionality is unbounded and scales with dataset size—we show this across nearly four orders of magnitude. journals.plos.org/ploscompbiol...

There is no substitute for American scientific investment. Since 1945, when Vannevar Bush convinced Truman of the merits of public research funding, only Russia and China have even tried to compete. If the USG stops funding science, the global economy will feel it.
America’s scientific prowess is a huge global subsidy
And it is now under threat

Our new @NatureHumBehav paper shows why we need a holistic pain biomarker framework. ML on blood tests, brain/bone imaging & genetics predicts clinical diagnoses but falls short on subjective pain. Adding psychosocial (mood, sleep, stress) boosts both. shorturl.at/vxxeO
Biological markers and psychosocial factors predict chronic pain conditions - Nature Human Behaviour
Fillingim et al. show that biological and psychosocial factors jointly predict conditions associated with chronic pain.

Good article touching all key points succinctly.

“U.S. government … research and development has accounted for at least 1/5 of total factor productivity growth in the U.S. business sector … a greater return than than private R & D has produced.”

Accelerated learning of a noninvasive human brain-computer interface via manifold geometry
Brain-computer interfaces (BCIs) promise to restore and enhance a wide range of human capabilities. However, a barrier to the adoption of BCIs is how long it can take users to learn to control them. W...
