I have been trying to tune a set of hyper-parameters of a SVC. The SVC is from LIBSVM.jl. It works when I use only one thread, but crashes indeterministically with multiple threads. Not only did it may or may not crash,…

Hello, I would like to perform crossvalidation and grid search using SVM (and XGBoost), using a parameter grid defined for each method. In MATLAB, within each split, I can run parfor, and each thread will train some mo…

Hi! How one can read files in the libsvm format in Julia? The LIBSVM.jl package seems to implement only algorithms. My current solution would be to read the file in python, save it in other format and then load it into J…

I am trying to use LIBSVM.jl with an imbalanced dataset. Providing weights for each class doesn’t seem to affect the result: using CSV using DataFrames using LIBSVM df = CSV.read("svm.csv", DataFrame) X = \[df.x1 df.x…
