💡 ML Concept of the Day: Types of Memory-Augmentation in Foundation Models

Memory is a key component of modern LLM architectures and one that is rapidly being incorporated into LLM frameworks. Memory allows LLMs to expands their contextual knowledge of a conversation by retrieving concepts from former interactions. Conceptually, LLM memory can be seen as a set of context-target pairs that can be aggregated to obtain next token probabilities.  There are many ways to incorporate memory into LLMs and they can have different effects. Most LLM memory forms can be grouped into three main groups:...
