google/vizier
Python-based research interface for blackbox and hyperparameter optimization, based on the internal Google Vizier Service.
This tool helps researchers, machine learning engineers, and data scientists automatically find the best settings for complex systems or models where the internal workings are unknown. You provide the system's adjustable parameters and a way to measure its performance, and it outputs optimized parameter combinations that maximize or minimize your desired outcome. It handles the iterative process of testing and refining parameters, enabling you to achieve superior results for your experiments or deployed systems.

Use this if you need to systematically tune the parameters of a 'black box' system, like a machine learning model, scientific simulation, or complex algorithm, to achieve optimal performance without understanding its intricate internal logic.
Not ideal if you need an explainable or interpretable model, as its focus is purely on optimizing outputs rather than understanding the internal parameter relationships.
