Great work! I realized there was a Zenodo link but I can't find it. How can I locate it?

We are very excited to share a preprint for our BehaveAgent, the first fully autonomous AI agent for universal behavior analysis. BehaveAgent is the result of rewarding work with ‪Zuwan Lin and the amazing team in JiaLiu's lab at @harvard.edu . 1/6

An autonomous AI agent for universal behavior analysis
Behavior analysis across species represents a fundamental challenge in neuroscience, psychology, and ethology, typically requiring extensive expert knowledge and labor-intensive processes that limit r...

I'm not entirely sure I understand what you mean - but essentially, in the paper we found that by making it a dual-classification problem (+ the clustering with high-confidence samples) we could refine the classifications of MA states (which, can be challenging to distinguish with the other states)

Check out our last paper on completely automatizing spike sorting using AI agents!
Not only makes the whole process human-free, but also provides an additional layer of information and interpretation that is completely unachievable by any other methods..

This paper looks interesting - it argues that you don’t need adaptive systems like Adam to get good gradient-based training, instead you can just set a learning rate for different groups of units based on initialization:

No More Adam: Learning Rate Scaling at Initialization is All You Need
In this work, we question the necessity of adaptive gradient methods for training deep neural networks. SGD-SaI is a simple yet effective enhancement to stochastic gradient descent with momentum (SGDM...

not necessarily the 'universal computation' but at least its a common language across subjects in neuro. I mean, we can't be sure we record the single-cell resolution same neurons from our very limited (and very downsampled) number of neurons.

Maybe not neurons, perhaps RNA??
Great episode of Brain Inspired with Hessam Akhlaghpour.
Do dynamical systems and/or RNNs implement universal computation? This discussion alone would be worth having.

Alright #neuroAI 😉 crew and those in #AI #ML perhaps interested in brain-inspired models and what’s next (not just foundation models please!). Here is my vision/roadmap of the next steps. A reflection & projection wrapped into a Perspective. Feedback very much welcomed. 🧠🧪👩‍🔬

Adaptive Intelligence: leveraging insights from adaptive behavior in animals to build flexible AI systems
Biological intelligence is inherently adaptive -- animals continually adjust their actions based on environmental feedback. However, creating adaptive artificial intelligence (AI) remains a major chal...

Juan! Love the list so far. I’d love to join if there’s room still :)

I *just* made a neurotech industry starter pack and added you to it.

Looks like it’s all organic so far due to the cool biohybrid work you just dropped!
