Can training a model on a dataset composed by real images and drawings hurt the training process of a real-world application model? I'm training a multi-label classifier that's supposed to be tested on underwater images. I'm wondering if feeding the model drawings of a certain class plus real images can affect the results badly. Was there a study on this? Or are there any past experiences anyone could share to help?
To my knowledge the deployment model (that you will test on underwater images) as inference will not have a negative effect. Yet drawings may even help differentiate some classes at training and inference. Provided that you won't use drawings in inference, adding them in training phase will not necessarily hurt the accuracy. Note that a drawing of a particular class should not be in the search domains of other classes, namely, a drawing of a particular class should not be the same with the other classes.
