In academia, the pinnacle of achievement is a pdf no one can access and I think that's beautiful

Can a single cell learn? Even without a brain, some microbes show simple forms of cognition. Can this basal cognition be engineered?

A black and white portrait of a young Werner Heisenberg

A black and white portrait of a young Werner Heisenberg

One hundred years ago, a 23-year-old postdoc named Werner Heisenberg completed a calculation that would become the heart of quantum mechanics, a radical yet stunningly accurate theory of the atomic and subatomic world.

How should #multisensory signals be combined when they are structured in time?

To explore this, we:
* Introduce a new multisensory task
* Compare several models

TLDR:
* Prior models perform suboptimally
* Our new model performs ≈ an RNN, while using less than 1/10th the number of parameters.

Expectation violations as an effective alternative to complex mentalizing in novel communication Neuroscience; Systems neuroscience; Social sciences

✨Excited to share that our new paper is now out in iScience!✨

🧠 We show that people can coordinate surprisingly well in novel interactions by violating others' expectations - without requiring deep, recursive reasoning about others’ beliefs.

Wonderful work by Shrey and Kayson in developing an XAI method for exploring the contribution of any computational unit (e.g., nodes, experts, communities, filters) within neural networks. It enables analysis of both their influence on each other and their overall impact on task performance.
