核心概念
ENAS algorithms' theoretical foundation is established by estimating the expected hitting time using a general method integrating theory and experiment.
要約
The content introduces Evolutionary Computation-based Neural Architecture Search (ENAS) algorithms, focusing on the expected hitting time (EHT) as a key theoretical issue. The proposed method estimates EHT lower bounds for (λ+λ)-ENAS algorithms with various mutation operators. The study validates the method on NAS-Bench-101 problem, marking the first theoretical foundation for ENAS algorithms.
The structure of the content includes:
Introduction to manually designed DNNs and motivation for NAS.
Classification of optimization algorithms used in NAS.
Overview of ENAS algorithms and their success in image classification.
Theoretical background on EHT analysis in EC community.
Various methods for analyzing EHT including fitness-level, convergence-based, drift analysis, and switch analysis.
Challenges in applying theoretical methods to NAS due to lack of explicit fitness functions.
Proposed CEHT-ENAS method framework integrating common configuration, search space partition, transition probability analysis, population distribution fitting, and hitting time analysis.
Preliminaries on NAS search space, mutation-based ENAS algorithms, Markov chain modeling.
Detailed steps for fitting population distribution based on experimental data collection and surface fitting techniques.
