Senior Data Scientist at OnePlanet Research center, working on digital twin models of the GI tract

[Ruben van Bergen @rubenvanbergen]

We are looking for a motivated MSc student to work on a data science project around synthesis of GI biomarker profiles for modeling gut health. Apply via the link or feel free to contact me with any questions! https://t.co/DlGcPtILjz

@Soren_Ltd Egg timers, surely?

Traveling waves are known to exist throughout the brain in a variety of forms — there are many hypotheses, but their exact computational role is debated.

Together with @wellingmax we built an RNN which exhibits traveling waves to see what it could do. Here’s what we think:

Are memories noisier versions of what we perceive? Fundamentally different? Seriously, think about it… Early visual cortex processes what we see around us, but also has information about images briefly held in mind. The two must be different… but how? TWEEPRINT ALERT! 🚨 🧵1/n

@ralfer @UiB Fantastic news - congratulations!

@PessoaBrain plausible solutions for it. But, we don’t know which the brain uses, or how to do it optimally in ANNs. Maybe “the binding question” would be a better term? 5/5

@PessoaBrain phase), or a pointer-like representation (where one of the features, e.g. the spatial or retinotopic location of the object, functions as a tether that is common to all other feature maps), etc. This isn’t a “problem” in the sense of being problematic – there are multiple 4/

@EelkeSpaak ...but you gotta draw the line somewhere?

(I'll see myself out)

@RL_Rademaker @SuryaGayet Damn straight

[Ruben van Bergen @rubenvanbergen]

Together, these results provide a first proof-of-principle for our new method. In future, we aim to scale this approach to more naturalistic input and more cognitively challenging tasks. 7/7

TLDR: Both perception and action benefit from representing the world in its natural building blocks - objects. 1/

[Ruben van Bergen @rubenvanbergen]

In addition, OBAI can select the right actions to achieve simple top-down goals, and imagine what the world will look like after this action. 6/
