NeuroWeaver is an autonomous evolutionary agent that designs EEG analysis pipelines by framing pipeline engineering as a discrete constrained optimization problem solved with large language model–driven code generation. It uses a Domain‑Informed Subspace Initialization to keep the search within neuroscientifically plausible solutions and a Multi‑Objective Evolutionary Optimization to balance performance, novelty, and efficiency. On five diverse benchmarks, NeuroWeaver produces lightweight pipelines that outperform state‑of‑the‑art task‑specific methods and match or exceed large foundation models while using far fewer parameters.

The paper introduces Gradient-based Sample Selection Bayesian Optimization (GSSBO), a method that builds the Gaussian process surrogate on a strategically chosen subset of samples rather than the full dataset. By using gradient information to eliminate redundant points while keeping diversity and representativeness, GSSBO achieves sublinear regret bounds and reduces the cubic computational cost of standard BO. Experiments on synthetic and real-world tasks show that this approach maintains comparable optimization performance while significantly cutting GP fitting time and resource usage.

The paper proposes a Bayesian decision framework for multiobjective optimization under uncertainty, focusing on maximizing the expected hypervolume over a finite set of input points. It demonstrates that gradient‑based stochastic optimization can be applied, especially when dominated points are handled carefully, and suggests using Gaussian Processes as differentiable surrogate models when direct gradients are unavailable. Additionally, the authors introduce active learning strategies via acquisition functions to build surrogate models tailored to the multiobjective problem and evaluate these strategies on simple analytical benchmarks.

The paper introduces KENDO, a unified framework that combines Ensemble Gaussian Processes with disagreement‑aware acquisition strategies to address hyperparameter selection in Bayesian optimization and active learning. By replacing costly hyperparameter sampling with a kernel ensemble and adaptive Bayesian weighting, KENDO‑BO and KENDO‑AL provide self‑correcting mechanisms tailored to their respective tasks. Experiments on synthetic and real‑world benchmarks show that KENDO‑BO matches or outperforms state‑of‑the‑art methods while cutting computational cost up to fivefold, and KENDO‑AL delivers better predictive calibration with up to 27‑times speedup compared to MCMC‑based baselines.
