AIF-C01 Question 69
Single answerA data science team is tasked with building a custom AI model using a foundation model for a natural language processing (NLP) application. The team has already chosen the foundation model and gathered domain-specific data. What should be the next step in the foundation model lifecycle to ensure the model is tailored to their specific use case?
- A
Pre-train the foundation model using the gathered data
- B
Fine-tune the foundation model using the domain-specific data
- C
Evaluate the foundation model before fine-tuning it
- D
Deploy the foundation model directly to production
Show answer and explanation
Correct answer: B
Explanation
The foundation model lifecycle involves fine-tuning the pre-trained model using domain-specific data after selecting the model and gathering relevant data. Fine-tuning ensures the model is adapted to the specific requirements of the application, which is critical for optimal performance in the use case.
- A. Incorrect.
Pre-training is the process of training a model from scratch on a massive dataset. Since the team has already chosen a pre-trained foundation model, this step is not applicable.
- B. Correct.
Fine-tuning adjusts the pre-trained model by training it on domain-specific data to improve its performance for the specific use case. This is the correct next step after selecting the model and gathering data.
- C. Incorrect.
Evaluation usually happens after fine-tuning to assess the model's performance. Evaluating the model before fine-tuning it would not address the need for customization.
- D. Incorrect.
Deploying the model directly to production without fine-tuning or evaluation would likely result in suboptimal performance since the model has not been adapted to the specific use case.
