Top Interview Questions & Answers
Q1: How does Multi-Head Attention work in Transformer models?
Multi-Head Attention projects Queries, Keys, and Values into multiple lower-dimensional subspaces, allowing the model to attend to information from different representation positions and semantic contexts simultaneously.
Frequently Asked Questions
Do I need heavy GPUs to learn NLP?
Free tiers on Google Colab and Kaggle provide T4 GPUs sufficient for running fine-tuning experiments with QLoRA.
