What does the Inner South anomaly project teach?
That "unusual" depends on what you compare against. Learners flag parking sensors with low battery voltages in Griffith and Forrest. One rule for all sensors mostly flags overhead units, which simply run at different voltages. Separate rules for each sensor type flag a different set, including 22 underground sensors the single rule missed.
The Inner South runs from Yarralumla and Deakin across to Kingston, Griffith and Narrabundah. Nearly half its homes are flats or apartments. Around Griffith and Forrest, the ACT Government has fitted hundreds of smart parking sensors, and their battery readings are public.
Facts last verified 13 October 2026. Teaching is online; no Inner South Canberra branch is claimed.

See the syllabusThe ABS calls this area South Canberra (SA3 80106). These are its 2021 Census QuickStats, read on 13 October 2026, with the bureau's 2025 estimate.
| Measure | Value |
|---|---|
| Residents, 2021 Census | 31,592 |
| Estimated residents, 2025 | 34,483 |
| Median age | 40 |
| Families | 8,109 |
| Private dwellings | 15,903 |
| Bedrooms per dwelling | 2.7 |
| Share | Inner South | ACT |
|---|---|---|
| Flat or apartment | 47.6% (6,309) | 19.4% |
| Managers among workers | 23.9% (4,269) | 17.9% |
| Worked at home | 13.8% (2,453) | 10.9% |
| Walked to work | 8.0% (1,419) | 4.0% |
Flats and apartments made up 47.6% of dwellings, the highest share of the eight districts on our pages.
Managers were 23.9% of workers and professionals 41.8%, and one worker in seven worked from home on Census day.
The 2021 count and the 2025 estimate come from different ABS methods and are shown side by side, never subtracted.
The Census ran during the pandemic, which probably inflated working from home that week. ABS figures are rounded and small counts nudged for privacy, so rows may not sum to totals; we keep the bureau's numbers as they are.
The ACT smart parking sensor list records 455 sensors, all in Griffith and Forrest, each with a type and a battery voltage. A maintenance team wants an alert for the weakest 10%. Learners compare one cut-off for every sensor with a separate cut-off for each type.
| Type | Sensors | Median | Range |
|---|---|---|---|
| Underground | 265 | 2.84 V | 2.00 to 3.61 V |
| Overhead | 190 | 3.61 V | 2.29 to 3.61 V |
| Rule | Cut-off | Flagged | Underground | Overhead |
|---|---|---|---|---|
| One rule for all | 2.58 V | 54 | 6 | 48 |
| Per type: underground | 2.74 V | 28 | 28 | none |
| Per type: overhead | 2.51 V | 22 | none | 22 |
Overhead sensors have a split: 108 read exactly 3.61 V and the other 82 sit between 2.29 and 2.81 V. A single cut-off lands in that lower cluster, so it flags overhead units almost exclusively.
Judged against their own kind, 28 underground sensors are in their weakest tenth. Only 6 of them were flagged by the single rule; 22 were missed.
The two approaches agree on 28 sensors. Twenty-six are flagged only by the single rule and 22 only by the per-type rules.
There is no record of which sensors actually failed, so neither rule can be scored for accuracy. And 453 of the 455 records were last edited in October 2019, so these voltages are an old snapshot. The lesson is about choosing the comparison group, and about saying plainly when a model cannot be checked.
Readings come from the ACTGOV Smart Parking Sensor Assets list on data.act.gov.au, CC BY 4.0, read on 13 October 2026. Parsing the voltage text, the percentiles and every flag count are our own Python calculation.
The fix is a groupby before the percentile, so each sensor is compared with its own kind.
| Step | Learner task |
|---|---|
| 1 | Parse "2.81V BATTERY VOLTAGE" strings into numbers and check none are missing. |
| 2 | Plot voltages by sensor type and describe the two shapes. |
| 3 | Flag the lowest 10% overall, then the lowest 10% within each type. |
| 4 | Compare the flagged sets and write what would be needed to say which is right. |
Step 4 is the AI lesson. A threshold rule is a tiny model, and like any model it needs ground truth to evaluate. Learners list what that would take: dates of battery replacements or sensor faults. Until then, the honest output is two candidate lists and a clear note about why they differ.
Decide who is "tall" in a class of mixed ages, first all together, then age by age.
Code both rules in Python, chart the flags and explain the overlap.
Set alert thresholds per device type, store or region instead of one global number.

Of 62,663 public tree records in Inner South suburbs, 37,533 are labelled exotic, about twice the 18,756 native.
The ACT barbecue list places 32 barbecues in the district, and 79 artworks are recorded too.

An anomaly detector run on all 455 sensors would happily report the overhead units as odd, because they are different, not because they are failing.
An Inner South learner who has split the data by type, and admitted there are no failure labels, knows what to ask before trusting any alert.
In our AI classes, every alarm comes with its comparison group. The longer argument is in is learning to code still worth it.
Every lesson is live over video, so learners join from home whether in Kingston or Red Hill.

One-to-one: about eight lessons a month with a dedicated teacher.

Let us know the learner's age and interests. Younger children can play the "who is tall" game; teenagers can build the two sensor rules.
Questions from Inner South families and adult learners.
The 2021 Census counted 31,592 people in the South Canberra area, median age 40. The ABS estimate for 2025 is 34,483.
A cut-off that marks readings as unusual, such as the lowest 10% of battery voltages.
Because the two types run at different normal voltages, so one cut-off mostly flags the type that is simply different.
We cannot say. There are no records of sensor failures, and the readings date mostly from October 2019.
Younger learners explore the idea with height and age games; the coded project suits teenagers and adults.
All 455 in the ACT list are in Griffith and Forrest: 242 in Forrest and 213 in Griffith.
No. Lessons are live online only, we have no Australian office, and our listed phone number is Indian.
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.
By level and pace, fifteen to twenty per group, not by age or suburb. One-to-one lessons suit anyone no group time fits.
Yes. Adults learn in their own groups or privately, often applying monitoring ideas at work.
