Investigating Hyperparameter Optimization and Transferability for ES-HyperNEAT: A TPE Approach
TL;DR
Hyperparameter optimization for ES-HyperNEAT using the Tree-structured Parzen Estimator (TPE) significantly improved accuracy on the MNIST task, achieving 29.00%. The optimized parameters showed transferability to Fashion-MNIST but limited success on simpler logic operations.
✦ Why It Matters
Consider using TPE for hyperparameter optimization in your own neuroevolution projects to enhance performance.
Key Takeaways
- Explore TPE for optimizing hyperparameters in neural networks.
- Test hyperparameter configurations on diverse tasks for better transferability.
- Utilize fewer resources while achieving higher accuracy in neural network training.
- Investigate the impact of hyperparameters on performance across different complexities.
How It Works
TPE is a Bayesian optimization method that models the performance of hyperparameters using a probabilistic approach, allowing it to efficiently navigate large search spaces. By focusing on promising regions of the hyperparameter space, TPE can identify configurations that yield better performance, as demonstrated in the study.
