Excuse me, does it mean that the basis of the input space and that of the output space is the same {v1, v2, ..., v8} at 45:25?Then, if this is true, when does change of basis happen?I get confused here, please help me, thanks a lot!####[['input space', 'Mathematical_Related_Concept', 'NEU'], ['output space', 'Mathematical_Related_Concept', 'NEU'], [' {v1, v2, ..., v8', 'Mathematical_Related_Concept', 'NEU'], ['basis', 'Mathematical_Related_Concept', 'NEU']]
