SMAC is a tool for algorithm configuration to optimize the parameters of arbitrary algorithms across a set of instances. This also includes hyperparameter optimization of ML algorithms. The main core consists of Bayesian Optimization in combination with a simple racing mechanism to efficiently decide which of two configuration performs better.
For a detailed description of its main idea, we refer to
Hutter, F. and Hoos, H. H. and Leyton-Brown, K.
Sequential Model-Based Optimization for General Algorithm Configuration
In: Proceedings of the conference on Learning and Intelligent OptimizatioN (LION 5)
SMAC v3 is written in python3 and continuously tested with python3.5 and python3.6. Its Random Forest is written in C++.
Besides the listed requirements (see requirements.txt), the random forest
used in SMAC3 requires SWIG (>= 3.0).
apt-get install swig
cat requirements.txt | xargs -n 1 -L 1 pip install
python setup.py install
If you use Anaconda as your Python environment, you have to install three packages before you can install SMAC:
conda install gxx_linux-64 gcc_linux-64 swig

The usage of SMAC v3 is mainly the same as provided with SMAC v2.08. It supports the same parameter configuration space syntax and interface to target algorithms. Please note that we do not support the extended parameter configuration syntax introduced in SMACv2.10.

SMAC v3 is developed by the ML4AAD Group of the University of Freiburg.
