Model Training Diagnostics & Hyperparameter Optimization
Identify training bottlenecks and auto-tune hyperparameters using Claude
What You Can Do
Upload your training logs, loss curves, and model architecture to Claude, which systematically diagnoses failures by analyzing convergence patterns, learning dynamics, and architectural inefficiencies. Claude recommends specific hyperparameter adjustments with scientific reasoning—learning rate schedules, regularization strengths, batch sizes, and architecture modifications—then guides you through iterative validation to confirm improvements.
Features
Analyzes logs and metrics to identify root causes of poor convergence, overfitting, underfitting, or gradient issues with explanations of why they're occurring.
Suggests specific tuning adjustments (learning rates, regularization, batch size, optimizer settings) with numerical reasoning tied to observed metrics.
Reads training and validation loss patterns to diagnose issues like learning rate too high, insufficient capacity, or data quality problems.
Reviews your model design for efficiency bottlenecks, improper layer sizes, gradient flow issues, and suggests targeted architectural changes.
Creates step-by-step tuning roadmaps with validation checkpoints so you test changes methodically without random search.
Evaluates multiple hyperparameter sets side-by-side to identify which combinations work best for your specific problem.
Explains what each metric (accuracy, F1, perplexity, loss) reveals about model behavior and how to prioritize which to improve.
Provides seeds, documentation, and experiment tracking recommendations to make your tuning process repeatable and shareable.
Example Output
Diagnostic Summary
Problem Identified: Loss plateaus at epoch 50 with validation accuracy diverging from training accuracy—signs of overfitting and learning rate decay.
Recommended Changes:
-
Learning Rate Schedule
- Current: 0.01 (constant)
- Proposed: 0.01 → 0.005 (decay at epoch 30) → 0.001 (epoch 60)
- Reasoning: Prevents overshooting optima; allows fine-tuning after exploration phase
-
Regularization
- Add L2 weight decay: 5e-4 (currently none)
- Add dropout: 0.3 before final layer
- Expected impact: ~2-3% validation accuracy improvement
-
Batch Size
- Increase from 32 to 128
- Effect: Smoother gradient estimates, faster convergence, reduced overfitting
Validation Plan:
- Train for 80 epochs with these settings
- Monitor: validation accuracy should improve by epoch 40
- If plateau persists, check data augmentation strategy
Success Criteria: Validation accuracy > 0.87 with loss trend downward through epoch 80.
