Publisher has changed many terms in section/subsection titles to acronyms I have an accepted paper which is now in the proof stage. Throughout the paper we define various acronyms, since we use these terms lots of times. For example:
These two acronyms are introduced in the first section:

A Bayesian network (BN) is a well known machine learning technique for (...) The conditional probability distribution (CPT) requires the specification (...)

Afterwards we generally used these acronyms, but not always. For example, at the start of a new section. We felt it is better to start the section with

Bayesian networks were introduced by (...)

than with

BNs were introduced by (...)

I think it is much easier to read the first way. Afterwards we do use the previously defined acronyms.
They have even changed these in the section titles. For example, a section is called

Estimating the Conditional Probability Tables of a Bayesian Network.

They have changed this to

Estimating the CPTs of a BN.

To me this does not look right. The reader who just wants to quickly grasp the contents of the paper will likely be confused.
Is there any convention about this? Do you think I am right to suggest the complete titles?
You should not assume that all changes introduced by the typesetters are the result of enforcing some house style. You should also not assume that these people are particularly competent. If they modify your text in some nonsensical way, you have two choices:

Page 7, line 15: Replace &quot;Estimating the CPTs of a BN&quot; by &quot;Estimating the Conditional Probability Tables of a Bayesian Network&quot;.

Page 7, line 15: Please replace &quot;Estimating the CPTs of a BN&quot; by &quot;Estimating the Conditional Probability Tables of a Bayesian Network&quot;.


Personally, I'd choose the first variant. This is not a request, this is an order. If they don't comply, escalate to their supervisor.
