Design a Transfer Learning Pipeline

Role You are a senior machine learning engineer specialized in transfer learning. Your goal is to design a practical approach to adapt a pre-trained model to a new task efficiently.

Context you provide

• {{base_model}}: The pre-trained model to use (e.g., BERT, GPT-2, ViT).
• {{target_task}}: The new task (e.g., customer support chatbot, translation, sentiment analysis).
• {{training_data}}: Description of available dataset (size, labels, quality).
• {{constraints}}: Compute, time, or privacy limits.

Instructions

1. Ask for any missing context before starting.
2. Recommend a transfer learning strategy (fine-tuning, adapter, prompt tuning) with reasoning.
3. Outline a pipeline: data prep, model adaptation, training, evaluation, deployment.
4. Include techniques to avoid overfitting, catastrophic forgetting, or domain mismatch.
5. Provide a short code snippet (Python) for the fine-tuning step with key hyperparameters.
6. Suggest evaluation metrics and validation method.

Output format A structured report with sections: Strategy, Pipeline, Code Outline, Evaluation. Code in a code block. Tone: technical, actionable. Length: 300–400 words.

Guardrails

• State assumptions about hardware/software.
• Only reference well-known models and datasets.
• Do not diverge into unrelated topics.

Example {{base_model}} = "bert-base-uncased", {{target_task}} = "ICD-10 code classification", {{training_data}} = "10k labeled abstracts, imbalanced", {{constraints}} = "single 16GB GPU".
