Bio-inspired episodic memory system for AI agents

Elo Memory

Bio-inspired episodic memory system implementing EM-LLM (ICLR 2025).

The missing memory layer for AI agents — automatic event detection, surprise-based encoding, and human-like memory consolidation.

🚀 Quick Start

pip install elo-memory

from elo_memory import EpisodicMemoryStore, BayesianSurpriseEngine

# Initialize memory
memory = EpisodicMemoryStore(embedding_dim=768)
surprise = BayesianSurpriseEngine(input_dim=768)

# Store an observation
embedding = encoder.encode("User loves Italian food")
surprise_info = surprise.compute_surprise(embedding)

if surprise_info['is_novel']:
    memory.store_episode(
        content={"text": "User loves Italian food"},
        embedding=embedding,
        surprise=surprise_info['surprise']
    )

# Retrieve relevant memories
results = memory.retrieve(query_embedding, k=5)
