Golang machine learning lib. Currently, it can be used to solve binary classification problems.
Hector support libsvm-like data format. Following is an sample dataset
1 1:0.7 3:0.1 9:0.4 0 2:0.3 4:0.9 7:0.5 0 2:0.7 5:0.3 ...
hector-cv.go will help you test one algorithm by cross validation in some dataset, you can run it by following steps:
go get github.com/xlvector/hector go install github.com/xlvector/hector/hectorcv hectorcv --method [Method] --train [Data Path] --cv 10
Here, Method include
hector-run.go will help you train one algorithm on train dataset and test it on test dataset, you can run it by following steps:
cd src go build hector-run.go ./hector-run --method [Method] --train [Data Path] --test [Data Path]
Above methods will direct train algorithm on train dataset and then test on test dataset. If you want to train algorithm and get the model file, you can run it by following steps:
./hector-run --method [Method] --action train --train [Data Path] --model [Model Path]
Then, you can use model file to test any test dataset:
./hector-run --method [Method] --action test --test [Data Path] --model [Model Path]
Following are datasets used in benchmarks, You can find them from UCI Machine Learning Repository
I will do 5-fold cross validation on the dataset, and use AUC as evaluation metric. Following are the results:
