Explain LLM training and evaluation
LLM Engineering: Training, Alignment, Evaluation, Monitoring, and Inference Optimization
Context
You are tasked with designing, aligning, evaluating, deploying, and optimizing transformer-based large language models (LLMs) for real-world applications.
Tasks
- Explain the processes of pretraining and finetuning transformer-based LLMs.
- Compare and contrast instruction tuning with Reinforcement Learning from Human Feedback (RLHF).
- Discuss effective strategies for reducing hallucinations in LLMs.
- Describe comprehensive methods for evaluating an LLM (including metrics like perplexity, task accuracy, and human evaluation) and how you would monitor its performance in a production environment.
- List and explain common inference optimizations applicable to LLMs, such as quantization and KV caching.
