Let’s distinguish between Large Language Models (LLMs) and Deep Learning Recommendation Models (DLRMs).
Large Language Models (LLMs)
- Purpose: LLMs are designed to understand and generate human language. They are used in applications like chatbots, translation, and text summarization.
- Architecture: Typically based on transformer architectures, LLMs use self-attention mechanisms to process and generate text.
- Training Data: Trained on vast amounts of text data from diverse sources to develop a broad understanding of language.
- Examples: GPT-4, BERT, and ChatGPT
Deep Learning Recommendation Models (DLRMs)
- Purpose: DLRMs specialize in recommendation systems, such as those used by e-commerce platforms, social media, and streaming services.
- Architecture: Often combine neural networks with collaborative filtering techniques. They use embeddings to represent users and items and then predict user preferences.
- Training Data: Trained on user interaction data, such as clicks, views, and purchase history, to learn patterns and make personalized recommendations.
- Examples: Facebook’s DLRM, which is used for personalized content recommendations
In summary, while LLMs focus on understanding and generating human language, DLRMs are tailored to make personalized recommendations based on user data.
Both are powerful in their respective domains but serve different purposes and are trained on different types of data.
