Of course. Here is a detailed explanation of the Day 1 concepts, framed as you might discuss them in an interview. Part 1: LLMs, Transformers, Prompt Engineering, and Embeddings 1. Transformers Interviewer: "Can you explain the Transformer architecture and what makes it so effective?" Your Answer: "The Transformer is a neural network architecture introduced in the paper 'Attention Is All You Need,' and it has become the foundation for most modern LLMs. Its key innovation was to move away from the sequential processing of Recurrent Neural Networks (RNNs) and instead process the entire input sequence at once using a mechanism called self-attention . This is built on several key components: Self-Attention: This is the core of the Transformer. For each word in a sentence, the self-attention mechanism calculates an 'attention score' relative to every other word in the same sentence. This allows the model to weigh the importance of other words when encoding...
