AI and programming classes in Casuarina

What does the Casuarina AI project discover?

Hidden patterns in a timetable, found without being told what to look for. Learners turn the Darwin bus timetable into a grid of 610 stops by 24 hours and factorise it with non-negative matrix factorisation. Three parts emerge: a morning rush, an afternoon rush and all-day service. The Casuarina interchange stops are about half all-day.

Casuarina is the bus hub of Darwin's northern suburbs, a small suburb of about 0.4 square kilometres where 15 bus routes meet. Few people live there, but buses on routes 1 to 5, 10, 12 and the Orbital services start, end or pass through it every weekday. Its timetable is a good place to see what unsupervised learning can find.

Casuarina in the Census

A tiny residential count around a big hub

From the 2021 Census QuickStats for the Casuarina suburb and locality (ABS SAL70051), read on 13 October 2026. The numbers are small, so the bureau's privacy adjustments matter more than usual.

Casuarina counts
MeasureValue
People406
Median age27
Families24
Private dwellings76
Suburb areaabout 0.42 sq km
Casuarina travel to work compared with the NT
ShareCasuarinaNT
Bus to work14.4% (42)2.1%
Walked to work12.4% (36)7.6%
Drove a car to work46.4% (135)63.4%

Bus users

Of Casuarina workers, 14.4% took the bus to work in 2021, roughly seven times the NT share.

Small numbers

With only 406 residents, a handful of people moves these shares a lot, so they are better read as signs than measurements.

Young

The median age was 27, below the NT median of 33.

Remember that 2021 was a pandemic year for travel. Because the ABS nudges small counts to protect privacy, every share above sits next to its count, and none are combined.

Signature project

Three patterns nobody labelled

For Wednesday 30 September 2026, a weekday the feed's weekday timetable runs, the Darwin bus GTFS lists 17,967 departures from 610 stops between 5am and 10pm. Learners turn each stop's departures into hourly shares and ask NMF to explain the 610 rows as mixtures of a few non-negative patterns.

Reconstruction error by number of patterns (our calculation, scikit-learn 1.7.2)
PatternsRelative error
10.763
20.594
30.514
40.424
50.325

Morning rush

One pattern puts 91% of its weight between 6am and 9am. It dominates 70 stops, typically ones served mainly in the morning peak.

Afternoon rush

Another puts 77% of its weight between 3pm and 6pm, and dominates 57 stops.

All-day service

The third is spread across the day and dominates 483 stops. The four main Casuarina stops are about half this pattern, with the rest split between the two rushes.

Why non-negative matters

PCA on the same matrix explains variance well, but its second component has 13 negative values among 24 hours: "minus departures" that no one can picture. NMF only adds patterns together, so every part reads like a timetable. More patterns always lower the error, so learners choose three for meaning, not for the smallest number.

Our timetable is the Territory's public bus data file for Darwin, published openly with an attribution licence. Deciding which stops sit inside Casuarina uses our own outline test against the bureau's suburb boundary, and the matrix, factorisations and tallies are ours as well.

In code

A matrix, NMF and some judgement

scikit-learn does the factorising. The judgement is in preparing the matrix and reading the parts.

Lesson steps
StepLearner task
1Count departures by stop and hour for one weekday the feed covers.
2Divide each row by its total so busy and quiet stops compare fairly.
3Fit NMF for 1 to 5 patterns and chart the errors.
4Name each of three patterns from its hours and check the Casuarina stops.

Step 2 is a real decision. Without it, the busiest stops dominate and the patterns describe them alone. Learners try both, and also compare with PCA to see why its negative values make the parts hard to explain. Calendar handling matters too: the feed switches its weekday timetable off on many dates in late 2026, so choosing the day comes first.

Younger learners

Mix two colours of paint to match a shade, the idea behind building things from positive parts.

Teenagers

Build the matrix, fit NMF and present the three patterns as charts.

Adults

Use NMF to find usage patterns in sales, energy or web logs at work.

Around Casuarina

The hub in numbers

A closer look at the stops inside the suburb, plus a note on Territory time.

Busiest stop

Trower Road after Linton Street carries 342 departures that Wednesday, more than any other stop within Casuarina.

Terminus

The Bradshaw Terrace terminus stop has 268 departures, and eight route names in the feed begin "Casuarina".

Territory time

Darwin keeps UTC+9:30 all year; the IANA database records its last daylight saving period ending in March 1944.

Outline used

We use the bureau's Casuarina boundary, about 0.42 square kilometres, which our test places within the City of Darwin. Territory school term dates are left out: we were unable to fetch them from an official source.

Is pattern-finding AI always right?

It always finds patterns. Deciding which ones mean something is up to people.

Ask NMF for five patterns and it will return five, with a lower error than three. Some of those extra parts may describe a single unusual stop rather than anything general.

A Casuarina learner who has named three patterns from their hours, and checked them against known stops, treats AI-found patterns as hypotheses to test rather than facts.

Our AI classes pair every pattern a model finds with a reason to believe it. The longer argument is in is learning to code still worth it.

FAQ

Casuarina AI and programming questions

Questions from Casuarina and northern Darwin families and adult learners.

How many people live in Casuarina?

The 2021 Census counted 406 people in the Casuarina suburb, median age 27. Few people live in the suburb itself.

What is non-negative matrix factorisation?

A way of breaking a table of non-negative numbers into a few additive parts, so each row is a mix of patterns.

Why three patterns?

Because three gave parts that make sense as timetables. More patterns lower the error but become harder to explain.

How is NMF different from PCA?

PCA allows negative values, which suits some tasks but makes timetable parts hard to read. NMF only adds positive parts.

Can children learn about AI patterns?

Younger learners explore pattern games; factorisation suits confident teenagers and adults.

How many bus routes serve Casuarina?

On the chosen Wednesday, 15 route names in the Darwin timetable stop inside the Casuarina suburb.

Do you have a centre in Casuarina?

No. Lessons are live online only, we have no Australian office, and our listed phone number is Indian.

What do Casuarina classes cost?

The first lesson is free. Group classes cost USD 100 a month for two live lessons a week, about eight a month, in groups of fifteen to twenty, and one-to-one classes cost USD 150 a month. You agree the course and time before paying.

Who would my child learn alongside?

Fifteen to twenty learners of similar level and pace, whatever their age or where they live. One-to-one lessons are there if no group time works.

Do you teach adults?

We do. Grown-up learners have their own groups or private classes, and many analyse data from their workplace.
