Lighting Descriptions: Natural vs Artificial

jackstev/hw1-text-lighting-natural-artificial

Short self-authored descriptions of how indoor spaces are lit, each labelled by whether the light is natural or artificial, plus explicitly marked synthetic training variants. Built for CMU 24-679 (Designing and Prototyping AI Systems), Homework 1. The classification task predicts the light source type from a short description of the space.

Composition

Column	Description
`source_id`	Identifier. Suffixed with method and copy when synthetic.
`text`	The description, roughly 200 characters.
`label`	Target. 0 = natural light, 1 = artificial light.
`label_name`	`natural` or `artificial`.
`parent_id`	Source text. Equals `source_id` when original.
`augmentation`	Method that produced the row, `none` if original.
`is_augmented`	False for written texts, True for generated variants.

The collected file labelled the artificial class "synthetic". It is renamed artificial here so that "artificial lighting" and "synthetic data" do not read as the same thing.

Collection

The author wrote every original text, describing spaces by how they are lit. Descriptions favour the behaviour of the light over naming its source: how it moves across a room through the day, where shadows fall, how evenly a space is covered, how surfaces look under it. Some texts do name a window or a bulb directly, which is realistic and is not treated as an error.

Texts were dictated aloud and then lightly edited to remove disfluencies. The provenance column records which texts went through that editing pass.

Splits

Split	Original texts	Synthetic texts	Total
`train`	70	1076	1146
`validation`	15	0	15
`test`	15	0	15

`test`	artificial	7

Originals were partitioned 30% to holdout, then 50% of that holdout to test, stratified by class. Both holdouts are entirely unaugmented.

Splitting precedes augmentation, so no variant of a held-out text can reach training. The notebook asserts that every synthetic text descends from a training parent.

Augmentation

Synthetic texts were generated from the training partition only, by four methods run over 4 copies each. Variants identical to their parent, and repeated variants from the same parent, were removed before packaging.

Training method	Stored texts
`internal_character_deletions`	279
`internal_character_swaps`	280
`none`	70
`within_line_word_swap`	279
`wordnet_synonym_replacement`	238

internal_character_swaps: two adjacent interior letters exchanged in up to 3 words.
internal_character_deletions: one interior letter removed from up to 3 words.
within_line_word_swap: two whole words exchanged, punctuation and spacing left in place.
wordnet_synonym_replacement: one word replaced by a synonym drawn from its first WordNet sense, matched on part of speech.

Label preservation. The first three methods are surface edits: they simulate typing slips and local word-order churn without altering which light source a description implies.

Synonym replacement is the method that could cross the class boundary, so the lighting vocabulary is protected from it. Words naming light sources and their settings, along with negation words, are excluded from replacement entirely. The class text notebook protects its own label-bearing terms for the same reason; this is the same mechanism applied to this domain. The notebook asserts, for every synonym variant, that each protected word appears exactly as often as it did in the parent.

Labels are copied from the parent and never recomputed.

Intended use and limitations

Suitable for teaching, text-augmentation practice and small-model prototyping. Not suitable for any real application.

Validation and test hold a small number of texts each. Accuracy on them moves in large steps and indicates little.
Every text is by one author describing spaces they had access to, so vocabulary, sentence rhythm and the kinds of rooms covered are narrow.
Synthetic texts carry no information beyond the training originals. Character edits and word swaps add surface variation, not new observations, and a model evaluated on them would score optimistically.
Character-level methods introduce deliberate misspellings. A model trained here sees noisier spelling than clean prose would present.
Synonym replacement uses the first WordNet sense rather than real word-sense disambiguation, so some replacements read oddly in context even when the label is unaffected.
Texts are not grouped by the space they describe. Where two descriptions cover the same room, they may fall in different partitions.

Ethical considerations

The texts describe rooms and lighting, not people. No names, faces or personally identifying information appear. The dataset carries no sensitive attributes and poses no foreseeable privacy risk.

AI usage disclosure

Every original text was composed by the author, who dictated each description aloud and assigned its label. No original text was written by a model, and no observation or label originated with one.

An LLM assistant (Claude) was used to write and refine the notebook code, the plots and this card, and to review the collected texts for balance, length and label leakage. The synthetic split is produced by the deterministic rule-based transforms in the accompanying notebook, not by a language model.
