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..

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...

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:

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.
