Machine Learning with Python
scikit-learn end to end on plant data: regression on energy against production, classification of motor-current signatures, the honest evaluation habits that make a model trustworthy, and a motor-fault classifier trained, tuned and reported the way an interviewer wants to see it.
Free to learn. Verifiable certificate £19 when you pass the final exam (optional, VAT included).

Sample certificate. Optional, issued when you pass the final exam.

Outcome
What you will be able to do
Frame a plant problem as regression, classification or clustering; fit and read linear and logistic regression; use trees, random forests, SVM, KNN and Naive Bayes; split without leakage, including by time and by machine; choose the right metric and read a confusion matrix; engineer physics-based features; build pipelines, cross-validate and tune with GridSearchCV; use k-means, PCA and IsolationForest; save and serve a model as an API.
- Fit a regression whose coefficients you can explain in kWh per unit
- Split train and test without leakage — by time for logs, by motor for fleets
- Read a confusion matrix and choose recall or precision with the person who owns the cost
- Engineer features from physics: imbalance, temperature rise, vibration ratios, rolling trends
- Cross-validate, tune with GridSearchCV and report a score with its spread
- Train a motor-fault classifier, save it with joblib and serve it as an API
Software
Google Colab (free). scikit-learn, Pandas and matplotlib are pre-installed.
Hardware
None.

How it works
How this course works
- Watch the video lessonsOne module at a time, at your own pace.
- Take the module quizA short quiz at the end of each module shows what stuck.
- Keep your notesWrite in My notes beside each module and ask the trainer if you are stuck.
- Practise in the labOptionalTry a task from the module in the EDWartens Lab, in your browser.
- Sit the final examPass it once you have been through the modules.
- Certificate, if you want oneOptionalPaid, and only after you pass. Anyone can check it online.
EDWartens Lab
Practise this in the EDWartens Lab
Train a model on plant data, move the decision threshold and weigh the cost of errors in the Lab's AI workbench.
Works alongside Machine Learning with Python. The Lab is ai for industry practice in your browser: no install, no hardware, free to use. Sign in as a learner and it opens with your account.

Why practise in a lab
Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.
- Practise safely, so a mistake costs nothing.
- The lab checks your work like a site test, so you know when it is right.
- Free, in your browser, with nothing to install.
Certificate
An optional certificate when you pass
Learning is free. Pass the final exam and you can have a certificate for £19, including VAT, with a number employers can check online. It records that you completed a free online course; it is not a regulated qualification or a CPD certificate.
- Your name, the course, its study time and your final exam score
- A unique certificate number and a QR code to its verification page
- Issued by Wartens Ltd; add it to your LinkedIn profile in one click
- Pay now or after you pass: it is issued the moment you pass the final
