# Gradient Clipping Experiment
|
| 2 |
+
|
| 3 |
+
## Objective
|
| 4 |
+
Demonstrate how gradient clipping stabilizes training by preventing sudden large weight updates caused by rare, high-loss data points.
|
| 5 |
+
|
| 6 |
+
## Task Breakdown
|
| 7 |
+
|
| 8 |
+
- [ ] Step 1: Implement simple PyTorch model (Embedding + Linear)
|
| 9 |
+
- [ ] Step 2: Create imbalanced synthetic dataset (990 'A', 10 'B' targets)
|
| 10 |
+
- [ ] Step 3: Training loop WITHOUT gradient clipping - record metrics
|
| 11 |
+
- [ ] Step 4: Training loop WITH gradient clipping (threshold=1.0) - record metrics
|
| 12 |
+
- [ ] Step 5: Generate comparison plots
|
| 13 |
+
- [ ] Step 6: Write summary report with findings
|
| 14 |
+
|
| 15 |
+
## Key Metrics to Track
|
| 16 |
+
1. Training loss per step
|
| 17 |
+
2. L2 norm of gradients (before clipping)
|
| 18 |
+
3. L2 norm of model weights
|
| 19 |
+
|
| 20 |
+
## Expected Outcome
|
| 21 |
+
- Without clipping: Spiky gradient norms when encountering rare 'B' samples
|
| 22 |
+
- With clipping: Bounded gradient norms, more stable training
