expressionsword-choiceword-usage

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.

: something that introduces: such as

a(1) : a part of a book or treatise preliminary to the main portion

(2) : a preliminary treatise or course of study

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.
