# Arbiter

- [Overview](https://deeplearning4j.konduit.ai/en-1.0.0-beta7/arbiter/overview.md): Arbiter hyperparameter optimization for DL4J — architecture, search strategies, configuration, and usage.
- [Layer Spaces](https://deeplearning4j.konduit.ai/en-1.0.0-beta7/arbiter/layer-spaces.md): Layer parameter spaces in Arbiter — configuration of per-layer hyperparameter search spaces for DL4J neural networks.
- [Parameter Spaces](https://deeplearning4j.konduit.ai/en-1.0.0-beta7/arbiter/parameter-spaces.md): Parameter space types for Arbiter hyperparameter search — continuous, integer, discrete, boolean, fixed, and composite spaces.
- [Visualization](https://deeplearning4j.konduit.ai/en-1.0.0-beta7/arbiter/visualization.md): Monitoring Arbiter hyperparameter optimization runs with ArbiterStatusListener and the UIServer.
