# Fitting a model requires the data-set to be prepared, in order to be a binary classification.
df = pd.read_csv(r'D:\IPM\ORSVM\DataSets\DataSets\Classification\monks-problems\monks1_train.csv')
y_train=df['label'].to_numpy() # convert y_train to numpy array
df.drop('label', axis=1, inplace=True) # drop the class label
X_train=df.to_numpy() # convert x_train to numpy array
# load test-set
df = pd.read_csv(r'D:\IPM\ORSVM\DataSets\DataSets\Classification\monks-problems\monks1_test.csv')
y_test=df['label'].to_numpy()
df.drop('label', axis=1, inplace=True)
X_test=df.to_numpy()
Initiate kernel

# fit the model and Capture parameters
Weights, SupportVectors, Bias, KernelInstance = obj.ModelFit(X_train,y_train)
