What's new

  • We have recently released ThunderGBM, a fast GBDT and Random Forest library on GPUs.
  • add scikit-learn interface, see here

Overview

The mission of ThunderSVM is to help users easily and efficiently apply SVMs to solve problems. ThunderSVM exploits GPUs and multi-core CPUs to achieve high efficiency. Key features of ThunderSVM are as follows. * Support all functionalities of LibSVM such as one-class SVMs, SVC, SVR and probabilistic SVMs. * Use same command line options as LibSVM. * Support Python, R, Matlab and Ruby interfaces. * Supported Operating Systems: Linux, Windows and MacOS.

Why accelerate SVMs: A survey conducted by Kaggle in 2017 shows that 26% of the data mining and machine learning practitioners are users of SVMs.

Getting Started

Prerequisites

  • cmake 2.8 or above
  • gcc 4.8 or above for Linux and MacOS
  • Visual C++ for Windows

If you want to use GPUs, you also need to install CUDA.

Quick Install

Download the Python wheel file (For Python3 or above).

Install the Python wheel file.

pip install thundersvm-cu90-0.2.0-py3-none-linux_x86_64.whl
Example
from thundersvm import SVC
clf = SVC()
clf.fit(x, y)

Download

git clone https://github.com/Xtra-Computing/thundersvm.git

Build on Linux (build instructions for MacOS and Windows)

ThunderSVM on GPUs
cd thundersvm
mkdir build && cd build && cmake .. && make -j

If you run into issues that can be traced back to your version of gcc, use cmake with a version flag to force gcc 6. That would look like this:

cmake -DCMAKE_C_COMPILER=gcc-6 -DCMAKE_CXX_COMPILER=g++-6 ..
ThunderSVM on CPUs
# in thundersvm root directory
git submodule init eigen && git submodule update
mkdir build && cd build && cmake -DUSE_CUDA=OFF .. && make -j
If make -j doesn't work, please simply use make. The number of CPU cores to use can be specified by the -o option (e.g., -o 10), and refer to Parameters for more information.

Quick Start

./bin/thundersvm-train -c 100 -g 0.5 ../dataset/test_dataset.txt
./bin/thundersvm-predict ../dataset/test_dataset.txt test_dataset.txt.model test_dataset.predict
You will see Accuracy = 0.98 after successful running.
