kmeans
C++ implementation of K-Means.
Usage:
kmeans <file>
where file is a list of points (space-separated), one point per line.
example:
1.23 4.56 7.89
3.21 6.54 9.87
Build instructions:
mkdir build
cd build
cmake ..
make
make test
Run on some sample data
There are some traces of sample data in the src/sample_data folder. data_N_D.txt contains N D-dimensional points.
For example, you can run kmeans on 200 2-dimensional points.
cd build
./kmeans data_200_2.txt 2
This produces a file means.txt that looks something like:
3.96207 -1.92886
-2.01688 -2.98501
