AI FOR OPTIMIZATION
Advanced Use of Automatic Algorithm Configuration
This tutorial delves into advanced Automated Algorithm Configuration (AAC) for both single- and multi-objective scenarios. It emphasizes moving beyond classical AAC, focusing on multi-objective optimization algorithms and improving anytime behavior, and addressing multiple performance objectives. The content covers formal definitions, configuration spaces, challenges like large search spaces and expensive evaluations, and various performance indicators. It also introduces AutoMOEA for automatic design of MOEAs and AutoMOPSO for designing MOPSO algorithms. The tutorial concludes with best practices for MO-AAC and discussions on use-cases in multi-modal MOPs and sparse neural networks.
Executive Impact
By leveraging Automated Algorithm Configuration (AAC) across single- and multi-objective optimization, organizations can achieve significant improvements in algorithm performance, resource efficiency, and decision-making robustness. AAC streamlines the design and tuning of complex algorithms, reducing manual effort and bias, leading to more statistically sound and powerful AI systems. This enables faster iteration, optimized resource utilization, and the discovery of novel algorithmic solutions for intricate enterprise problems.

Automated Algorithm Configuration (AAC) systematically finds optimal parameter settings for algorithms. It addresses challenges like vast configuration spaces and expensive evaluations. Key aspects include defining the configuration space (name, type, range, conditional parameters, forbidden combinations) and performance measures.
AutoMOEA is a framework for automatically designing state-of-the-art Multi-Objective Evolutionary Algorithms (MOEAs). It replicates well-known MOEAs using a template with configurable components (e.g., MatingPool, Replacement, Archiving, Preference) and then tunes these components. This approach enables the discovery of novel and highly effective MOEAs.
Improving anytime behavior means configuring algorithms to produce high-quality solutions regardless of when they are interrupted. AAC, guided by performance measures like hypervolume of solution quality vs. time (SQT) curves, can automatically optimize for this. This reduces manual effort and bias in tuning for robustness across different termination criteria.
MO-AAC prevents premature commitments to preferences by considering multiple performance objectives simultaneously. It identifies a set of configurations that represent the trade-off between conflicting objectives. Approaches include off-the-shelf EMOAs, ParEGO, MO-ParamILS, and MO-SMAC, each with its strengths in handling complex parameter spaces and intensification.
