I can\'t ensure that NAS\'s result always outperforms than human-designed architectures. This situation is related with sub-optimal point. If we use gradient-based search strategy, the result might fail to reach to global optimal point due to natual of gradient update method. Moreover, if we limit a search space due to computational cost, NAS\'s result might not the best architecture due to lack of candidates. Therefore, if you want to get optimal architecture, you have to set enough search space and great search algorithm.

Hi, Mary! You explained NAS’s strengths and limitations well and showed good understanding of gradient-based search and search space issues. Your reasoning is strong, but grammar, prepositions, and word choice need some polishing. With clearer phrasing and careful verb forms, your explanation will be very professional and precise. Great technical insight!
