  • Example: In OpenAI’s GPT-3 model, each word token is embedded into a dense vector representation based on its surrounding context, allowing the model to capture nuanced semantic relationships within the text.
• Attention Mechanisms:
  • Attention mechanisms play a crucial role in guiding the text generation process by allowing the model to focus on relevant parts of the input sequence.
  • By assigning attention weights to different tokens in the input, LLMs prioritize important information and incorporate it into the generated output.
  • Example: Transformers, the architecture underlying many LLMs, utilize self-attention mechanisms to compute attention scores for each word token, enabling the model to attend to relevant context when generating text.

Role of Context and Conditioning

• Contextual Prompts:
  • LLMs often generate text based on contextual prompts provided by the user, which serve as starting points or cues for the model to continue generating coherent text.
  • The quality and specificity of the prompt influence the generated output, as the model uses the provided context to guide its language generation process.
  • Example: When prompted with the phrase “Once upon a time,” an LLM might generate a story beginning, leveraging its learned language patterns and storytelling conventions.
• Conditioning on Input:
  • LLMs condition their text generation process on the entire input sequence, incorporating information from preceding tokens to generate subsequent ones.
  • This conditioning allows the model to maintain coherence and consistency throughout the generated text, ensuring that each token aligns with the overall context.
  • Example: In language translation tasks, an LLM conditions its text generation process on the source language input, producing a translated output that preserves the semantic meaning and syntactic structure of the original text.

Generating Coherent Text Outputs

• Sampling Strategies:
  • LLMs employ various sampling strategies to generate text outputs, ranging from deterministic methods like greedy decoding to stochastic approaches like beam search and sampling.
  • These strategies influence the diversity, fluency, and novelty of the generated text, balancing between generating coherent outputs and exploring alternative language possibilities.
  • Example: Beam search, a commonly used decoding algorithm, explores multiple candidate sequences during text generation, selecting the most probable continuation based on a predefined beam width.
• Temperature Scaling:
  • Temperature scaling is a technique used to control the diversity of text generated by LLMs by scaling the logits (log-odds) of the softmax distribution during sampling.
  • Lower temperatures result in more deterministic outputs, while higher temperatures lead to more diverse and exploratory outputs.
  • Example: By adjusting the temperature parameter during text generation, users can fine-tune the balance between generating conservative, high-confidence responses and exploring more creative, low-confidence responses.

Real-World Examples of Text Generation
