How a Submission Is Classified

Classification lets a reader follow one slice of a field without reading all of it. arXiv has used subject codes like cs.LG and stat.ML since 1991: a primary archive that decides where a paper is announced, plus cross-lists that surface it to neighbouring communities. The scheme below borrows that machinery and applies it to a region instead of a discipline.

There are two axes, because a single-axis scheme breaks the moment a paper is about hurricanes and about time-series forecasting. The subject axis records what the work is about in the Caribbean. The method axis records what machine learning it uses. Everything published by AIC carries a code on both.

  • One primary subject code, beginning cai., which decides which section editor handles the submission and where it is listed.
  • One primary method tag, beginning ml., which decides which reviewers are approached.
  • Up to three cross-list codes from either axis, which surface the work to adjacent readers without changing who owns the decision.

Authors propose their own codes at submission. Editors adjust them where a paper is filed in the wrong place, and tell the author when they do. Misclassification is never a ground for rejection.

Two conditions apply to every code on this page. The work must apply machine learning or artificial intelligence rather than only discuss it, and it must engage the Caribbean, its diaspora, or the small-state and Small Island Developing State conditions the region shares with the Pacific, the Indian Ocean and comparable economies. A technically strong paper that meets neither condition is out of scope, and desk review will say so within five business days rather than send it to reviewers.

Choosing Your Codes

In each example the primary subject code is the domain the finding belongs to, and the primary method tag is whatever a reviewer needs to be able to check.

01

Forecasting outage duration after a hurricane

Primary: cai.NRG and ml.TSA
Cross-list: cai.CLM, ml.GEO

The finding is about the electricity grid, so it files under energy rather than climate, even though the trigger is a storm. Climate readers still find it through the cross-list.

02

A speech dataset and recognizer for Jamaican Patois

Primary: cai.CUL and ml.NLP
Cross-list: cai.MTH, cai.SOC

A dataset paper cross-lists to methods so that other builders find it, and to ethics because language data raises consent and ownership questions that reviewers should weigh.

03

Testing a credit model built abroad on local applicants

Primary: cai.FIN and ml.XAI
Cross-list: cai.MTH, ml.SUP

The contribution is the fairness and transfer audit, not the model, so the method tag is interpretability and evaluation rather than supervised learning.

Revising the Scheme

A classification scheme that never changes stops describing the field it was built for. arXiv has added, split and retired categories repeatedly across three decades, in response to what researchers were submitting.

The AIC scheme is reviewed once a year by the Editor-in-Chief and the section editors, against the distribution of submissions received. A code that attracts almost nothing is merged. A cross-list that repeatedly carries more traffic than its parent becomes a subject area of its own. Changes are announced before an edition opens, never during one, and existing published records keep the codes they were assigned.

If your work fits nowhere on this page, write to editor@caribbeanaijournal.org with the paper and a one-line case for the code you think is missing. Proposals are considered at the annual review, and sooner where a whole line of regional research is going unclassified.
