The bureau introduces small random changes into its tables to protect privacy, so the parts of a table may not add to its total. We print the bureau's numbers as they appear and do not compute totals of our own from them. Signature project ## Predicting Gordon from its neighbours: least squares against the lasso Transport for NSW publishes monthly Opal entries for every station. We took 23 months for the eight North Shore line stations from Roseville to Wahroonga and asked how well seven of them predict Gordon. | Neighbour | Correlation with Gordon | Least squares weight | Lasso weight, penalty 500 | | --- | --- | --- | --- | | Roseville | 0.956 | -3,369 | 8,415 | | Lindfield | 0.939 | 20,850 | 1,927 | | Killara | 0.912 | 2,455 | 0 | | Pymble | 0.924 | -22,706 | 0 | | Turramurra | 0.907 | -16,825 | 0 | | Warrawee | 0.937 | 4,728 | 4,863 | | Wahroonga | 0.935 | 30,633 | 0 | | Model | Inputs kept | Error on training months | Error on unseen months | | --- | --- | --- | --- | | Average of training months only | 0 | 13,400 | 15,633 | | Least squares, all seven neighbours | 7 | 1,366 | 8,329 | | Lasso, penalty 2,000 | 3 | 3,572 | 4,285 | | Lasso, penalty 10,000 | 1 | 9,087 | 9,547 | ### Why the signs go wrong All eight stations follow the same seasonal rhythm, so their columns are nearly copies of each other. Least squares can then trade large positive and negative weights against each other and still fit the training months closely. ### What the lasso does It adds a cost proportional to the size of every weight. Inputs that add little are pushed to exactly zero, and as the penalty grows the model keeps three neighbours, then two, then Roseville alone, then none. ### What the test shows Least squares fits the past most closely yet does worse than the lasso on the future. The three-input lasso gives up some training accuracy and roughly halves the error on months it never saw. ### A fit is not a forecast An error of 1,366 entries a month on the training data looks excellent, and an error of 8,329 on the next six months tells the real story. Every learner in this project sees the same lesson professional data scientists learn the hard way: judge a model only on data it was not allowed to study. Every weight and error above is our own calculation from Transport for NSW's published monthly figures, with each station's entries standardised before fitting. The weights describe a statistical model, not anything about how people actually choose stations, and the six test months are too few to make firm claims about which model is better in general. Regularisation in practice ## Experiments that sharpen a learner's judgement With the lasso working, a few further runs show why choosing inputs matters in every machine learning system. | Experiment | What to watch | What it teaches | | --- | --- | --- | | Sweep the penalty from 0 upwards | Inputs dropping out one by one | The regularisation path | | Swap the lasso for ridge regression | Weights shrink but none reach zero | L1 against L2 penalties | | Choose the penalty by cross-validation | The penalty with the smallest error on held-out months | Tuning without peeking at the test set | | Add the month of the year as an input | Whether neighbours still matter | Confounding by a shared cause | The pattern of several inputs telling the same story is everywhere: test scores in related subjects, sensor readings from nearby devices, word counts in similar documents. A model that cannot cope with it gives unstable explanations, and the lasso is one of the clearest ways to see the problem and fix it. ### Teenagers Plot the eight stations together, fit least squares by hand with NumPy, and watch the weights change when one month is removed. ### University students Write coordinate descent for the lasso, compare it with scikit-learn, and trace the full path of weights. ### Adults Build forecasting models at work that stay simple enough to explain and stable enough to trust. Transport for NSW, Ku-ring-gai Council, the NSW Department of Education and the statistics bureau make these datasets public and have no connection with us. The regressions, weights and test errors were produced by our own code. Around Ku-ring-gai ## Twentieth-century schools and a line of stations A few more facts from the same open sources. ### Schools of the 1900s The NSW schools file lists 24 government schools in the council area. The earliest first teachers were at Lindfield Public School in 1903, Warrawee Public School in 1906 and Roseville Public School in 1913. ### Gordon Station Gordon recorded 168,651 Opal entries in August 2026, averaging 150,171 a month across the 23 months in our data. ### Four terms in 2027 Eastern division schools run Term 1 from Wednesday 3 February to Friday 9 April 2027 and Term 4 from Tuesday 12 October to Monday 20 December. Another view of the same data Exits are published alongside entries. Comparing them station by station, and asking why a month might show more people leaving a station than entering it, is a good warm-up in reading data carefully before modelling anything.

[AI and ML Masterclass](/courses/ai-ml-masterclass-complete-college)[Data Science Course](/courses/data-science-complete-masterclass-college)Coding and AI ## An AI can fit a model in seconds. Why should a Ku-ring-gai learner build one? Because the hard part of machine learning is not fitting a model, it is knowing when the fit is misleading. Ask an AI assistant to predict Gordon from its neighbours and it will happily run a regression and report a tight fit. Unless prompted, it is unlikely to mention that the inputs are nearly duplicates, that a weight of minus 22,706 on Pymble makes no physical sense, or that the error on future months is six times the error on past ones. A learner who has built the lasso on real station data looks for exactly those warning signs: inputs that move together, explanations that flip sign, and accuracy measured only on the data the model learned from. Those habits matter more as AI tools make models cheaper to produce. In 2026 anyone can fit a model, and the Ku-ring-gai learner who checks it on unseen months is the one whose predictions hold up. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Delivery ## Roseville to Wahroonga, one classroom online The eight stations in our project run the length of the council area's railway, and a live online lesson serves every one of their neighbourhoods equally. ### At home Lessons happen at the learner's own desk, so no evening is lost to driving, parking or waiting for a lift home. ### Following NSW Lessons respect the NSW stages and terms, pause for school holidays, and can tie projects to senior computing and maths courses. ### A proper trial The free opening lesson teaches real content; the teacher then suggests a level, course and time, and nothing is charged that day. ### Groups of fifteen to twenty Learners are matched on skill and pace rather than age or postcode, alongside classmates from elsewhere. ### Two lessons weekly A fixed weekly rhythm of two lessons, roughly eight a month, with holiday breaks planned in advance. ### Teachers in India A 6:30pm Ku-ring-gai lesson in summer starts at 1pm India time; during the Sydney winter it starts at 2pm there. Two time zones, one timetable Sydney moves its clocks forward on Sunday 4 October 2026 and back on Sunday 4 April 2027; India never changes. We quote every lesson in Sydney time, so the family's timetable stays fixed through both changes. Fees ## Ku-ring-gai class fees Simple pricing in three parts. First class**USD 0** A free first lesson that ends with a recommended course. Group tuition**USD 100** A month of group lessons, usually eight, with fifteen to twenty learners. Private tuition**USD 150** Around eight private lessons a month with one teacher. Invoices outside India are in US dollars, so every Ku-ring-gai family pays the same rate and no local price list exists. Payment starts only after the trial has fixed a course and time, and the pricing page sets out holidays, missed lessons and format changes.

FAQ ## Ku-ring-gai AI and programming questions What Ku-ring-gai families and adult learners usually want to know. ### How many people live in the Ku-ring-gai council area? 124,076 at the 2021 Census, according to the QuickStats for the Ku-ring-gai local government area, with a median age of 42. ### What is lasso regression? Lasso regression is linear regression with an extra cost on the absolute size of every weight. The cost pushes unhelpful weights to exactly zero, so the model chooses a small set of inputs and is less likely to overfit. ### What is the Ku-ring-gai station project? Learners predict Gordon Station's monthly Opal entries from the seven other North Shore line stations between Roseville and Wahroonga. Least squares fits the past closely but errs by 8,329 entries a month on unseen months; a three-input lasso errs by 4,285. ### Why did ordinary regression give Pymble a negative weight? Because all the stations move together, their inputs are almost interchangeable, and least squares can balance large positive and negative weights against each other. The fit looks good but the individual weights stop meaning anything. ### Does this help with senior maths or computing? Yes. The project uses statistics and programming that support senior maths and computing courses. Any work a school assesses must be the student's own; we explain methods and do not write assessed work. ### Is this suitable for adults changing careers? Yes. Adults learning data science or machine learning work on the same kind of project, with more attention to validation and to explaining models to others. ### Can younger children learn with you? Yes, from age six. Younger children begin with Scratch and simple patterns; the regression project on this page is for older students. ### Is there a Modern Age Coders centre in Ku-ring-gai? No. Lessons are live online only and we have no premises in Australia. A computer with sound and a reliable connection is all that is needed; our phone number is in India. ### How much are AI classes for Ku-ring-gai learners? The first lesson is free. Then a group place costs USD 100 a month for two live lessons a week, about eight in total, with fifteen to twenty learners, or USD 150 a month for the same schedule one to one. Course, format and time are agreed before paying. ### How big are classes? Fifteen to twenty learners at the same level, grouped by ability and goals rather than age or suburb. One-to-one teaching is offered when no group fits the needed time.
