the title of section 2.1 of book "Deep Learning and Convolutional Neural Networks for Medical Image Computing" is
Introduction on Deep Learning Methods in Mammography
I see Introduction "to" more than Introduction "on", so, which one is more appropriate and idiomatic?
Best Answer
They mean slightly different things. In this instance, introduction means something that introduces, or is a preliminary, to something else.
If it were "introduction to," instead of "introduction on," the emphasis would not be on what the introduction is about, but what it is supposed to do: help you understand, in this case, deep learning methods in Mammography.
According to Ngram, "introduction to" is vastly more common, but without more context, I can't say which I think is more appropriate.
