3.5 Debugging Neural Systems¶
Role at Stage 3: Deep Learning¶
Diagnose the ordinary reasons neural networks fail before blaming the architecture. This part is one capability inside the stage. It should leave behind an artifact, measurements, and a short explanation of failure modes.
Explanation¶
This part has 3 sub-parts because the topic needs that many learning units to feel natural. Some stages have more parts and some have fewer; the structure follows the topic, not a fixed template.

| Sub-part folder | What it explains |
|---|---|
| 3.5.1 Sanity Checks and Tiny Overfit Tests | Sanity Checks and Tiny Overfit Tests is the working skill inside Debugging Neural Systems that helps you build the stage artifact, A PyTorch training project with loops, validation curves, checkpoints, ablations, and debugging notes, while collecting enough evidence to trust the result. |
| 3.5.2 Gradient Problems | Gradient Problems is the working skill inside Debugging Neural Systems that helps you build the stage artifact, A PyTorch training project with loops, validation curves, checkpoints, ablations, and debugging notes, while collecting enough evidence to trust the result. |
| 3.5.3 Numerical Stability and Precision | Numerical Stability and Precision is the working skill inside Debugging Neural Systems that helps you build the stage artifact, A PyTorch training project with loops, validation curves, checkpoints, ablations, and debugging notes, while collecting enough evidence to trust the result. |
What a Person Who Masters This Part Can Do¶
- Explain how Debugging Neural Systems supports a pytorch training project with loops, validation curves, checkpoints, ablations, and debugging notes..
- Build and inspect this artifact: Apply a training debugging checklist.
- Measure progress with: Record before-after curves, runtime, memory, and the fix.
- Debug at least one failure mode before moving to the next part.
Build and Measure¶
Build: Apply a training debugging checklist.
Measure: Record before-after curves, runtime, memory, and the fix.
Tests¶
Take one 30-question exam after studying this part. It opens in a new browser tab so the study page stays available.
