Terms related to neural networks · 3.4.3
convolution
a mathematical operation that slides a dot product or cross-correlates the input data
What this term settles
This is the sense the standard gives convolution. A firm is free to use another sense, but then the difference belongs in its own glossary rather than in an assumed shared language.
Who it binds
The entry has no shall in it, and the force of convolution comes from use: once it appears in a procedure or a supplier term, this is the meaning the reader may rely on.
What to do in your practice
Map the places convolution appears in policy, procurement and system records. Where the word is used without the entry behind it, add the citation or replace the sentence.
Evidence an auditor or regulator asks for
- A controlled vocabulary entry for convolution with the citation 3.4.3, an owner and a review date.An auditor can check that convolution is controlled rather than assumed.
- A model architecture note that names the network form and the layers used. The row names convolution.Shows convolution in use in the artefact the firm relies on, not only in a glossary.
- A test record that shows the behaviour the architecture was chosen for. The record carries the convolution entry and its date.The architecture note uses the network name as a marketing label with no layer or training detail behind it. The gap is tested against convolution.
Common gaps this page catches
- convolution is used in the network architecture note without a written definition, so two teams can mean different things.
- The entry for convolution exists in a glossary but not in the system record, so the two disagree at the point of use.
What to prepare before the amendment lands
Add the entry to the register, give it an owner and a review date, and test it against one live artefact this week. The test is the evidence; the register row alone is not.
How to test it here
Take one live artefact rather than a template, find the sentence or field where convolution is used, and put this page beside it. Record the answer, the artefact and the date, because that record is the evidence and a glossary entry on its own is only an intention.
What this page does not claim
The page does not reproduce the standard, certify the firm or predict the wording the amendment will use; it states convolution at the claim level "definition" and stops where the public record stops.
Common questions
- What does convolution mean in ISO 22989?
- a mathematical operation that slides a dot product or cross-correlates the input data
- What evidence should we keep for 3.4.3?
- A controlled vocabulary entry for convolution with the citation 3.4.3, an owner and a review date. A model architecture note that names the network form and the layers used. The row names convolution.
- Is convolution a requirement?
- No: convolution is a definition or clause of a terminology standard, and it becomes binding only when a firm writes it into a policy, a contract or a procedure, or when another standard incorporates it.
