"### Generative Agent Memory Components\n",
"\n",
"This tutorial highlights the memory of generative agents and its impact on their behavior. The memory varies from standard LangChain Chat memory in two aspects:\n",
"\n",
"1. **Memory Formation**\n",
"\n",
" Generative Agents have extended memories, stored in a single stream:\n",
" 1. Observations - from dialogues or interactions with the virtual world, about self or others\n",
" 2. Reflections - resurfaced and summarized core memories\n",
"\n",
"\n",
"2. **Memory Recall**\n",
"\n",
" Memories are retrieved using a weighted sum of salience, recency, and importance.\n",
"\n",
"You can review the definitions of the `GenerativeAgent` and `GenerativeAgentMemory` in the [reference documentation](\"../../reference/modules/experimental\") for the following imports, focusing on `add_memory` and `summarize_related_memories` methods."
