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

Training failure diagnosis

Analyzes logs and metrics to identify root causes of poor convergence, overfitting, underfitting, or gradient issues with explanations of why they're occurring.

Hyperparameter recommendations

Suggests specific tuning adjustments (learning rates, regularization, batch size, optimizer settings) with numerical reasoning tied to observed metrics.

Loss curve interpretation

Reads training and validation loss patterns to diagnose issues like learning rate too high, insufficient capacity, or data quality problems.

Architecture critique

Reviews your model design for efficiency bottlenecks, improper layer sizes, gradient flow issues, and suggests targeted architectural changes.

Iteration planning

Creates step-by-step tuning roadmaps with validation checkpoints so you test changes methodically without random search.

Comparative configuration analysis

Evaluates multiple hyperparameter sets side-by-side to identify which combinations work best for your specific problem.

Metric interpretation

Explains what each metric (accuracy, F1, perplexity, loss) reveals about model behavior and how to prioritize which to improve.

Reproducibility guidance

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:

  1. 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
  2. Regularization

    • Add L2 weight decay: 5e-4 (currently none)
    • Add dropout: 0.3 before final layer
    • Expected impact: ~2-3% validation accuracy improvement
  3. 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.

What's Included

  • Diagnostic framework: Structured approach to analyze loss curves, metrics, and logs to pinpoint what's wrong with your training.
  • Hyperparameter tuning workflow: Interactive decision tree for selecting which hyperparameters to adjust based on observed failure mode.
  • Loss curve interpreter: Reference guide explaining what patterns mean: divergence, plateaus, oscillation, slow convergence, and what causes each.
  • Architecture review checklist: Questions to evaluate layer sizes, skip connections, activation functions, and other design choices that impact training.
  • Comparison templates: Structured formats for tracking different hyperparameter configurations and their results side-by-side.

  • Machine Learning Engineers
  • Data Scientists training custom models
  • AI Researchers optimizing architectures
  • ML Operations Engineers tuning production models
  • Deep Learning practitioners debugging convergence issues

Best For

  • Debugging why your model isn't converging or is overfitting
  • Systematically tuning hyperparameters without random grid search
  • Understanding what your loss curves and metrics are telling you
  • Optimizing model architecture for better training dynamics
