Disadvantages

Although Neural Architecture Search (NAS) has many potential benefits, it also has some drawbacks and difficulties:

• High Computational Cost: The significant computational cost of NAS is one of its main disadvantages. It is frequently necessary to train multiple neural networks in order to sift through the enormous space of possible architectures. This process can be laborious and resource-intensive, particularly for large-scale datasets and complex models.
• Implementation Complexity:Putting NAS algorithms into practice can be difficult and calls for knowledge of both optimization and machine learning methods. The overall complexity is increased by creating a search space that works, choosing relevant search tactics, and optimizing performance estimation techniques.
• Overfitting to Particular Tasks: NAS may overfit to the particular tasks or datasets it is optimized for, which could lead to architectures that are poorly suited to novel tasks or datasets. It can be more difficult to ensure robust generalization when additional methods like multi-objective optimization or transfer learning are needed.
• Scalability Issues: It is difficult to scale neural networks efficiently because as the size and complexity of the neural network grow, the search space expands exponentially. This can result in diminishing returns, where the gains in performance are outweighed by the computational cost.
• Evaluation Bottleneck: One major bottleneck in NAS is effectively estimating the performance of candidate architectures. Since it is not possible to fully train every candidate architecture to convergence, proxy tasks or performance estimation techniques must be used, which may not always accurately reflect the architectures' true performance.
• Resource Constraints: Although the goal of NAS is to identify efficient architectures, the initial search procedure may require an excessive amount of resources. Without access to specialized hardware or cloud computing services, conducting a comprehensive NAS may not be feasible for organizations with limited computational resources.
• Reproducibility and Benchmarking: Because search spaces, search strategies, and performance estimation techniques vary widely, it can be difficult to replicate NAS experiments and benchmarking results. It may be challenging to compare the outcomes of various studies or implementations due to this variability.

Despite these obstacles, continued study and developments in NAS are attempting to resolve a number of these problems in order to improve NAS's usability, effectiveness, and accessibility in the search for the best neural network architectures.
