Hi, thanks for response  
I have a cnn for color image classification, the accuracy of the model was very low, after changing the contrast, the accuracy improved.
The values I considered for colorjitter include:
transforms.ColorJitter(brightness=(1.5), contrast=(0.9), saturation=(1.5), hue=(-0.1,0.1))
I want to know the values must be between 0 and 1 ?
Are the values I considered correct?
I do not understand the interpretation of the original document.Thanks, guide me.
