Evolutionary Bi-Level Neural Architecture Search with Training: A Framework for Color Classification
This work presents an Evolutionary Bi-Level Neural Architecture Search with Training (EB-LNAST) approach for simultaneously optimizing the architecture, weights, and biases of a Multi-Layer Perceptron (MLP) through a bi-level optimization strategy. At the upper level, EB-LNAST generates candidate MLP architectures, while at the lower level, it tunes their weights and biases based on the dataset. The proposed approach is evaluated on a color classification task using a custom experimental setup, as well as on the Wisconsin Diagnostic Breast Cancer (WDBC) dataset.

What is EB-LNAST?
Evolutionary Bi-Level Neural Architecture Search with Training (EB-LNAST) tackles the complex challenge of designing optimal neural networks by simultaneously optimizing architecture, weights, and biases. It leverages a bi-level optimization strategy: the upper level defines the network structure, while the lower level refines its training parameters. This leads to highly efficient and compact models without compromising predictive accuracy.
How EB-LNAST Works
The core of EB-LNAST lies in its innovative bi-level optimization strategy, which uses Differential Evolution (DE) at both stages to explore the solution space effectively and avoid local minima.

This novel approach intelligently balances complexity and performance, employing Differential Evolution (DE) to navigate the vast search space more efficiently and robustly than traditional methods.
Key Findings & Performance
EB-LNAST was rigorously tested on a real-world color classification task and a complex medical dataset, demonstrating its superior capabilities.
Color Classification Case Study
On a real-world color classification task, EB-LNAST achieved a peak Fẞtest score of up to 0.9720, demonstrating high precision. The model consistently classified colors with 95.1% to 98.0% accuracy across various classes, showcasing its robust performance in a complex, multi-modal problem environment.
WDBC Dataset Case Study
When applied to the Wisconsin Diagnostic Breast Cancer (WDBC) dataset, EB-LNAST achieved an accuracy of 0.9883 and an Fẞtest of 0.9879. Remarkably, this performance was competitive with, and in most cases superior to, state-of-the-art machine learning algorithms. Crucially, EB-LNAST delivered these results with up to a 99.66% reduction in model size compared to highly tuned MLP models, proving its ability to generate extremely compact and efficient architectures.
| Feature | EB-LNAST | Traditional ML/DNN (Tuned) |
|---|---|---|
| Architecture Optimization | Automated Bi-Level Search | Manual/Trial & Error (or limited search) |
| Model Size | Up to 99.66% Reduction | Often Larger, Over-parameterized |
| Predictive Performance | Superior/Competitive (e.g., Fẞtest 0.988) | Good, but often with larger models |
| Robustness/Consistency | Narrower Confidence Interval | Wider Confidence Interval |
| Exploration of Search Space | Efficient (DE-based) | Can get trapped in local minima |
| Generalization | Improved | Risk of Overfitting |
