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:
