From Problem to Concept
This article continues the discussion of memory recursion in AI systems, as described in The Day My AI Started Talking to Itself. If you haven't read it yet, we recommend starting there — it covers the problem itself and its mathematical inevitability.
Once it became clear that memory recursion isn't a specific bug but a fundamental architectural problem, the question arose: how do we actually solve it?
Simple solutions like "just apply decay" or "lower the weight of AI outputs" turned out to be half-measures:
- Decay kills important memories along with noise
- Lowering weights turns AI into a "mirror" of the user
- Deleting old data deprives the system of long-term memory
We needed something more fundamental. Not a "patch," but an architectural principle.
Disclaimer: What This Article Is About
Important to understand: This article is not the ultimate truth. It's a reflection on a possible concept, an attempt to formulate universal principles for preventing recursion in AI systems with multi-layered memory.
The principles proposed here:
- ✓ Are based on analysis of real recursion cases
- ✓ Are inspired by how human consciousness works
- ✓ Have mathematical justification
- ✓ Are practically implementable
But this is not the only possible solution. Rather, it's a starting point for reflection and experimentation.
Nevertheless, we believe these principles are significantly better than many current approaches and have every right to exist and be implemented.
The Key Idea: Learning from the Human Brain
The question wasn't why this happens (that's already clear), but how to prevent it without losing system utility.
And here an unexpected source of inspiration helped us: human consciousness.
The Human Brain's Solution
Think about how a healthy human mind works:
-
There's a core identity - your personality, values, fundamental beliefs
- These DON'T change from daily interactions
- They filter and interpret new information
-
There's verified knowledge - facts you're confident about
- These change slowly, with evidence
- They're resistant to casual contradictions
-
There's working memory - current context, recent conversations
- These change rapidly
- They fade naturally when no longer relevant
-
There's critical thinking - new information is evaluated
- Does it contradict what I know?
- Is the source trustworthy?
- Am I thinking about this too much?
Humans don't get stuck in loops because we have layers with different rules.
The Architecture: Three-Layer Memory
Here's the proposed approach that theoretically should prevent recursion while preserving useful memory:
┌─────────────────────────────────────────────────────┐
│ LAYER 1: IDENTITY CORE │
│ • System principles and behavior patterns │
│ • Meta-principles: diversity, relevance, honesty │
│ • Weight: ALWAYS 1.0 │
│ • Never changes from interactions │
└─────────────────────────────────────────────────────┘
↓ interprets everything through this lens
┌─────────────────────────────────────────────────────┐
│ LAYER 2: VALIDATED KNOWLEDGE │
│ • User preferences and facts │
│ • Confirmed through multiple interactions │
│ • Weight: 0.8-1.0 │
│ • Slow temporal decay (6-12 month half-life) │
│ • Must be consistent with Layer 1 │
└─────────────────────────────────────────────────────┘
↓ provides context for
┌─────────────────────────────────────────────────────┐
│ LAYER 3: CONTEXTUAL MEMORY │
│ • Recent conversations and AI outputs │
│ • Weight: 0.3-0.6 │
│ • Fast temporal decay (1-2 week half-life) │
│ • Requires validation to move to Layer 2 │
└─────────────────────────────────────────────────────┘
Why This Should Work
Layer 1 (Identity) acts as an attractor—the system always gravitates back toward its core principles, preventing drift.
Layer 2 (Knowledge) stores what matters long-term, but only after validation. AI outputs rarely reach here.
Layer 3 (Context) is disposable. AI outputs start here with low weight and naturally fade unless confirmed by external sources.
Six Universal Principles
Principle 1: Asymmetric Source Trust
Not all sources are equal:
SOURCE_TRUST = {
"USER_EXPLICIT": 1.0, # User directly stated
"USER_IMPLICIT": 0.8, # Inferred from behavior
"EXTERNAL_VERIFIED": 0.7, # Verified external data
"AI_OUTPUT": 0.3, # Own generation
"AI_RECURSIVE": 0.1, # Nth-order generation
}
Critical: This is built into the architecture, not a config option.
Principle 2: Temporal Dynamics with Exceptions
def temporal_factor(memory, age_days):
# Facts and preferences don't decay
if memory.type in ["FACT", "PREFERENCE", "IDENTITY"]:
return 1.0
# Recent confirmations reset decay
if has_recent_confirmation(memory):
return 1.0
# Layer 3: fast decay (7 day half-life)
if memory.layer == 3:
return exp(-0.1 * age_days)
# Layer 2: slow decay (180 day half-life)
if memory.layer == 2:
return exp(-0.004 * age_days)
Key insight: Decay applies to context, not to knowledge.
Principle 3: Contradiction Detection
def integrate_memory(new_memory, system):
# Check 1: Contradicts identity?
if contradicts(new_memory, identity_core):
if new_memory.source == "AI_OUTPUT":
return reject(new_memory)
else:
# User contradicts identity - note but don't integrate
new_memory.weight *= 0.5
new_memory.layer = 3
# Check 2: Contradicts validated knowledge?
conflicts = find_conflicts(new_memory, layer2_memories)
if conflicts:
if new_memory.source_trust > conflicts.source_trust:
update_knowledge(conflicts, new_memory)
else:
new_memory.disputed = True
new_memory.layer = 3
# Check 3: Recursion pattern?
if is_recurring_theme(new_memory) and new_memory.source == "AI_OUTPUT":
new_memory.weight *= 0.2
flag_for_review(new_memory)
Principle 4: Homeostatic Regulation
The system automatically corrects itself:
def regulate_system(window_days=7):
# Measure theme diversity
theme_entropy = shannon_entropy(recent_themes(window_days))
# Detect dominant patterns
for theme in all_themes:
frequency = theme.count / total_interactions
expected = 1.0 / num_themes
# Theme appears 3x more than expected?
if frequency > expected * 3:
if theme.source_majority == "AI_OUTPUT":
# This is recursion - suppress
suppress_theme(theme, factor=0.1)
else:
# Legitimate interest - but diversify
boost_alternative_themes(exclude=theme)
# Measure drift from identity
identity_distance = measure_drift_from_core()
if identity_distance > threshold:
apply_identity_restoration()
This function can run automatically every few days, catching problems before users notice them.
Principle 5: Gradient-Based Retrieval
Memory retrieval considers multiple factors:
def retrieve_memories(query):
scores = []
for memory in all_memories:
# Base relevance
relevance = cosine_similarity(memory.embedding, query.embedding)
# Source modifier
source_mod = memory.source_trust
# Layer modifier
layer_mod = {1: 1.0, 2: 0.8, 3: 0.5}[memory.layer]
# Temporal modifier (with exceptions)
temporal_mod = temporal_factor(memory, age_days)
# Anti-spam (retrieval frequency)
retrieval_count = memory.retrievals(window=7)
anti_spam = 1.0 / (1.0 + retrieval_count * 0.3)
# Identity alignment
identity_alignment = cosine_similarity(
memory.embedding,
identity_core.embedding
)
# Combined score
score = (
relevance *
source_mod *
layer_mod *
temporal_mod *
anti_spam *
(0.7 + 0.3 * identity_alignment)
)
scores.append((memory, score))
# Diversity-aware selection
return select_diverse_top_k(scores, k=10, diversity=0.3)
Principle 6: Monitoring Dashboard
To control system effectiveness, the following set of metrics is proposed:
┌──────────────────────────────────────┐
│ AI Memory Health Dashboard │
├──────────────────────────────────────┤
│ Shannon Entropy: 2.4 ✓ │
│ Target: > 2.0 │
│ │
│ Identity Distance: 0.12 ✓ │
│ Target: < 0.20 │
│ │
│ Self-Reference Rate: 8% ✓ │
│ Target: < 15% │
│ │
│ Layer Distribution: │
│ Layer 1: 5% ✓ │
│ Layer 2: 25% ✓ │
│ Layer 3: 70% ✓ │
│ │
│ Recent Interventions: │
│ Theme "balance" suppressed │
│ Reason: 35% frequency, AI source │
│ Date: 2 days ago │
└──────────────────────────────────────┘

Expected Results
This architecture is a conceptual development based on analysis of recursion problems in existing systems. Here's what can be expected from its implementation:
Current systems (with recursion):
Theme diversity: 0.28 (low)
Self-reference rate: 35%
User complaints: Weekly
Memory useful lifespan: ~2 weeks
Expected results (with proposed architecture):
Theme diversity: 0.6+ (healthy)
Self-reference rate: < 10%
User complaints: Significant reduction
Memory useful lifespan: Months to years
These projections are based on theoretical analysis and require practical validation.
The Key Insight
The human brain doesn't treat all information equally. It has:
- A stable core (personality)
- Trusted knowledge (facts)
- Disposable context (working memory)
Your AI needs the same structure.
Common Questions
Q: Doesn't this make the AI less "intelligent"?
A: No—it makes it more stable. Intelligence without stability is insanity.
Q: What if the user wants to change the AI's behavior?
A: Layer 2 can be updated with validated user input. Layer 1 remains stable but can be manually adjusted by developers.
Q: How do I define the Identity Core?
A: Start with meta-principles: be helpful, be diverse, be accurate, be relevant. Refine based on your use case.
Q: Does this work with vector databases?
A: Yes! The layer/source/weight fields work with any storage system.
Q: What about very large memory systems (millions of entries)?
A: Layer 3 can be aggressively pruned. Layer 2 grows slowly. Layer 1 is tiny. Theoretically, the architecture should scale well, but this requires validation.
Conclusion
AI memory recursion isn't a bug—it's a mathematical inevitability in systems without thoughtful architecture.
We've proposed an approach based on structuring memory like a healthy mind—with different layers and rules for each. The six principles described above form a framework that may help prevent recursion.
But let's repeat once more: this is a concept that requires validation. Perhaps in practice nuances will emerge that we haven't considered. Perhaps someone will find a more elegant solution.
We're not seeking the status of "the only correct approach." Rather, we want to start a discussion about how to properly design memory for AI systems. If this concept proves useful even just as a starting point—we'll consider the task accomplished.
