Main features

• Very simple but versatile API
• Thoroughly tested code base
• Compatible with any python machine-learning framework
• Optimize:
  • Anything from simple models
    to complex machine-learning-pipelines
  • Multi-level ensembles
  • Deep neural network architecture
  • Other optimization techniques (meta-optimization)
  • Or any function you can specify with this API
• Utilize state of the art optimization techniques like:
  • Simulated annealing
  • Evolution strategy
  • Bayesian optimization
• High performance: Optimizer time is neglectable for most models
• Choose from a variety of different optimization extensions to improve the optimization

Installation

The most recent version of Hyperactive is available on PyPi:

pip install hyperactive

Experimental algorithms

The following algorithms are of my own design and, to my knowledge, do not yet exist in the technical literature. If any of these algorithms still exist I ask you to share it with me in an issue.

Random Annealing

A combination between simulated annealing and random search.

Scatter Initialization

Inspired by hyperband optimization.
