Practise in the 3D lab

Practise the habits a Keras model needs, on simpler models: seeing overfitting in the gap, splitting without leakage and choosing recall, precision and the threshold.

Train and testWatch

Optional. Skip it whenever you like: it never blocks your progress or your certificate.

Course project, about 7 hours

A surface-defect classifier: baseline CNN, augmentation, transfer learning, one table

You get 1,200 greyscale 128×128 surface images in four classes (ok, scratch, dent, blob). Split by file once. Train three models on Colab, with a GPU if one is available. Report them on one sealed test set with per-class recall. Explain three predictions with Grad-CAM. Export a TFLite model and report its size.

Practise what you learn in the free 3D 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.

Why learn with EDWartens

What you get with this course, and what comes after it.

  • Free from the first lesson to the final assessment.
  • Practice in a free 3D lab in your browser, with nothing to install.
  • Video lessons with written notes and a project.
  • An optional certificate that anyone can verify online.
  • Free internships to keep practising afterwards.

Common questions

Do I need a GPU?

No. Google Colab's free tier usually offers a GPU when one is available. The type and quota vary, and sessions end. The models in the course are small and train in minutes on one. Set the runtime type to GPU in the first cell of each notebook.

How much maths?

You see gradient descent and backpropagation once, in twenty lines of NumPy, so you know what the framework does. After that Keras does the calculus and you do the engineering. Nothing in the assessments asks for derivatives.

What are the projects in the Deep Learning with TensorFlow and Keras course?

There are two projects. The first is a surface-defect classifier on 1,200 images. You compare a baseline CNN, augmentation and transfer learning on one sealed test set. You use per-class recall and Grad-CAM, and export to TensorFlow Lite. The second is a vibration-window classifier comparing a 1-D CNN with an LSTM. It adds an autoencoder anomaly score trained on healthy data only.

Should I do this before or after the OpenCV course?

After, ideally: the OpenCV course teaches you what a convolution filter is by making you tune one by hand, and it shows when classical vision is enough. This course is for when it is not.

Is the Deep Learning with TensorFlow and Keras course really free?

Yes. Every module, practice task, project and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.

What certificate does the Deep Learning with TensorFlow and Keras course give?

An EDWartens Certificate of Completion, issued when you have finished the modules and passed the final assessment (the project is optional practice), with a verification code anyone can check. It is not a vendor credential and is never described as one.

Who made the video lessons in the Deep Learning with TensorFlow and Keras course?

The creators named in the Credits block at the foot of this page, on their own YouTube channels. EDWartens did not make the videos and the creators are not affiliated with EDWartens. What EDWartens wrote is the study plan, the notes, the practice tasks, the projects and the assessments.

Do I have to use the lab?

No. The lab is optional practice. You can skip it whenever you like, and it never blocks your progress, the final assessment or your certificate.

Is the lab free?

Yes. Every lab level for this course opens in your browser, free, with nothing to install.

What topics does the Deep Learning with TensorFlow and Keras course cover, module by module?

The Deep Learning with TensorFlow and Keras course has 13 modules. It opens with "What a neural network is, and why now", goes through "The neuron, activation and loss", "Training well: dropout, early stopping, imbalance", "Sequences: 1-D CNNs, RNNs, LSTMs and autoencoders" and "The project: surface defects end to end" and ends with "Final assessment". The full list with minutes is under "What you learn" on this page.

What can I do after the Deep Learning with TensorFlow and Keras course?

After the Deep Learning with TensorFlow and Keras course: Say when a neural network beats a random forest, and when it does not; Build and train a Keras model with the right loss, early stopping and dropout, and read its curves; Feed images from folders and signal windows from streams through a fast tf.data pipeline. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.

What software and hardware do I need for the Deep Learning with TensorFlow and Keras course, and does it cost anything?

For the Deep Learning with TensorFlow and Keras course, software: Google Colab (its free tier usually offers a GPU runtime when one is available). TensorFlow and Keras are pre-installed. Hardware: none. A Raspberry Pi is optional for the deployment module. The course itself is free.

Is the Deep Learning with TensorFlow and Keras course suitable for me, and what level is it?

Deep Learning with TensorFlow and Keras is rated intermediate. Intermediate. Needs the Machine Learning with Python course, or equivalent: train/test discipline, metrics, Pandas. It is written for engineers, developers and students applying AI to real work, and takes about 27.4 hours at your own pace.

Which jobs use the skills from the Deep Learning with TensorFlow and Keras course?

Skills from the Deep Learning with TensorFlow and Keras course (for example: say when a neural network beats a random forest, and when it does not) are used in roles such as AI engineer, machine learning engineer, data analyst and automation developer, and in machine learning engineer work. The course gives you practical evidence of the skill; it does not promise a job, and employers decide on experience and interview.
