Mechanism for feature learning in neural networks and backpropagation-free machine learning models. (https://pubmed.ncbi.nlm.nih.gov/38452048/)

These scientists wanted to understand how our brains, or neural networks, learn important patterns in information so they can make accurate predictions. To do this, they came up with a special mathematical method called average gradient outer product (AGOP). This method helps to show how neural networks learn these patterns.

They tested AGOP on different types of neural networks like those used for language models, image recognition, and other tasks. They found that AGOP was able to capture the patterns these networks were learning. What was really cool is that AGOP could also be used in other types of machine learning models that couldn't find these patterns on their own.

In conclusion, the scientists discovered a key way that neural networks learn important information and how this method can be used to help other machine learning models learn as well.
