Researchers demonstrate that recurrent cortical circuits generate traveling waves acting as a computational engine in the visual cortex. These neural traveling waves allow the brain to build internal representations of the external world, enabling the prediction of upcoming sensory inputs and the replay of temporal memories. This biological mechanism is functionally analogous to how large language models learn statistical structures from text; instead, these waves encode environmental regularities into synaptic networks through experience.
- Traveling waves modulate moment-to-moment perception.
- They enable the inference of causes for noisy sensory inputs.
- These dynamics allow for short-term predictions and memory replay.

With deep learning, the ROI for having clean and high quality data is immense, and this is realized in every phase of training. For context, the era right before BERT in the text classification world was one where you wanted an abundance of data, even at the expense of quality. It was more important to have representation via examples than for the examples to be perfect. This is because many Al systems did not use pre-trained embeddings (or they weren't any good, anyway) that could be leveraged by a model to apply practical generalizability. In 2018, BERT was a breakthrough for down-stream text tasks,
