@nleadholm and @jhawkins share thoughts on the concept of object classes, focusing on how the brain distinguishes between specific objects and general categories. The team discusses morphology, affordances, and learning in the hippocampus, while debating how class representations form and guide perception. We conclude that classes could be represented using the different models that naturally emerge at different levels of the hierarchy, making it possible for an object to be an instance of many classes at once.
In the end, @nleadholm recaps some of the key takeaways from the previous week’s research meeting, where we discussed shared learning, attention, and the inputs to columns.
