“…For example, Liu et al [21] randomly selected a small number of medical images from the entire dataset to train the searched architectures. However, random sampling may lead to the removal of some representative samples, thus greatly weakening the generalization of the architecture trained in the subset [22], [23]. This will lead to an inaccurate evaluation of the performance.…”

“…Then, they removed the samples that have a small impact on the performance of architectures. Na et al [23] used the data entropy to analyze five sampling methods (i.e., random, entropy top-k, entropy bottom-k, forgetting events, and k-center). They concluded that the low-entropy samples could help search for competitive architectures when the size of the subset is small.…”

“…EPC-DARTS [17] then introduces the side operation to improve the performance of the searched model under lower sampling rates (e.g., 1/8) of input channels. Proxy Data [15] finds that proxy data constructed by existing data selection methods are not always appropriate for NAS, and designs a new proxy data selection method for efficient NAS. Different from these works, we present the first attempt to investigate the robustness of different NAS under kinds of proxies, which is complementary to the above works that find better proxies for specific NAS.…”

“…On the other hand, proxies are non-negligible as they affect the computation and memory cost as well as the search effectiveness and efficiency. Therefore, a few recent works [14], [15], [17] propose to find better proxies to realize more efficient NAS. Different from these works, we propose to investigate the robustness of different NAS under kinds of proxies for the first time.…”
