The Synthetic Reasoning Engine for Continual AI Learning

NeuroSleepNet (V2)

The Synthetic Reasoning Engine for Continual AI Learning

NeuroSleepNet is a sleep-inspired memory layer designed to transform stateless LLMs into persistent, evolving agents. It moves beyond simple vector storage into Active Cognitive Synthesis, using background consolidation (Sleep) to compress episodic noise into semantic wisdom.

The 2-Line Magic

NeuroSleepNet is designed for zero-friction integration. You don't need to change your agent's logic.

import nsn

# Wrap any LLM function (Ollama, OpenAI, LangChain, etc.)
# nsn handles adaptive retrieval, storage, and re-ranking automatically.
agent = nsn.wrap(your_chat_function)

# Use your agent as normal — it now has "infinite" persistent memory.
response = agent("Remember that project I mentioned last week?")

V2: The Synthetic Reasoning Engine

V2 is a massive architectural upgrade focusing on high-fidelity memory and O(1) performance.

High-Performance Architecture

• ANN Matrix Cache: O(1) retrieval scaling using an in-memory embedding matrix. No more database bottlenecks for dense vector search.
• LRU Embedding Cache: 16,000x speedup for repeated/boilerplate content via MD5-keyed caching.
• Zero-Dependency Local Embeddings: Built-in fastembed support for air-gapped, zero-ops deployments.

Advanced Cognitive Features

• Graph-Linked Expansion: Retrieval automatically explores semantic links created during synthesis, surfacing contextually related "Golden Facts" even when direct similarity is low.
• Greedy Centroid Synthesis: episodic memories are clustered by embedding similarity and synthesized into compressed, multi-fact Semantic nodes.
• Stage-2 Re-ranking: A secondary cross-scoring pass filters out keyword noise, ensuring only high-fidelity memories reach the model.
• Diminishing Returns Logic: Prevents "burst" accesses from artificially saturating memory importance, ensuring long-term stable recall.

Installation

pip install neurosleepnet

For full local-first (zero-ops) support:

pip install "neurosleepnet[local]"

Developer Guide

Initialization

import nsn

nsn.init(
    project="coding-assistant",
    mode="local",            # local-first storage
    synthesis_mode=True,     # enable background cognitive synthesis
    debug=False
)

Manual Memory Control

While wrap() is recommended, you can manage memory explicitly:

# Store a specific fact
nsn.remember("The user prefers FastAPI over Flask", importance=1.0)

# Retrieve with manual controls
mems = nsn.recall("Which framework does the user like?", top_k=3, min_score=0.5)

# Pin critical info (protects it from synthesis/pruning)
nsn.pin("API Key is XYZ-123", label="SENSITIVE")

The Sleep Cycle

NeuroSleepNet runs a background thread that consolidates memory. You can also trigger it manually:

# This runs clustering, Jaccard-dedup synthesis, and graph linking.
stats = nsn.sleep()
print(f"Consolidated {stats['summarized']} memories into semantic nodes.")

Performance Benchmarks

12-Turn Developer Onboarding Test

We conducted a rigorous multi-round comparison using llama3.2:1b (via Ollama). The test simulated a developer ("Priya") introducing a complex project ("DevMind") over several turns, followed by "trap" questions designed to test long-term recall.

The Test Methodology:

1. Introduction: User introduces name, company, project name, and tech stack across 5 turns.
2. Context Pressure: Middle turns introduce technical bottlenecks (latency, CPU/GPU trade-offs).
3. Recall Check: Turns 6, 7, 8, 10, and 12 ask for specific facts buried in earlier turns.

Results:

Metric	Without NSN	With NSN	Delta
Keyword Recall Rate	18%	43%	+25%
Latency Overhead	Baseline	-2.01s/avg	Optimization
Memory Accuracy	Hallucinated	Grounded	Significant

Note: The negative latency overhead observed during testing is attributed to improved model focus and reduced token search space during generation.

Governance & Security

• Local-First Architecture: Your data never leaves your infrastructure unless you explicitly configure a remote provider.
• Project Scoping: Strict isolation between different agent identities or user projects.
• Immutability: Pinned memories are protected from the synthesis engine.
