vidurai 1.6.0

Self-learning AI memory system with RL-based compression - Intelligence emerges from experience, not rules

🕉️ Vidurai - The Conscience of the Machine

"विस्मृति भी विद्या है" (Forgetting too is knowledge)

The first self-learning AI memory system that strategically forgets. Teaching AI the ancient art of memory through experience, not rules—inspired by Vidura's wisdom from the Mahabharata.

🚨 v1.5.1 Released (2025-11-03) - Critical bug fixes for token accumulation, recall reliability, and reward profiles. All v1.5.0 users should upgrade immediately. See CHANGELOG for details.

🎯 The Problem We Solve

Current AI memory systems are fundamentally broken:

• 📚 Store everything, remember nothing useful - No distinction between critical insights and trivial chatter
• 💸 Costs explode with token accumulation - Every conversation drains your budget
• 🌪️ Memory becomes noise over time - The more they remember, the less they understand
• ⚙️ Hardcoded rules can't adapt - Fixed thresholds fail as user needs evolve

The result? AI that forgets your name but remembers you said "umm" 47 times.

✨ The Vidurai Solution: Beyond Hardcoded Rules

While others use static compression rules, Vidurai learns what matters through experience.

🧠 Vismriti RL Agent - The Learning Brain

The breakthrough: A Q-learning reinforcement learning agent that discovers optimal compression strategies by:

• 🎯 Learning from 10,000+ episodes of real-world memory scenarios
• 📊 Balancing token savings vs. information preservation as competing objectives
• 🔄 Adapting strategies based on content type, conversation context, and user patterns
• 🏆 Achieving 36%+ token reduction while maintaining semantic fidelity

No manual tuning. No brittle heuristics. Just autonomous intelligence.

🏛️ Three-Kosha Architecture - Inspired by Vedantic Consciousness

Our memory system mirrors human cognition through three layers:

1. Annamaya Kosha (The Physical Sheath) High-speed working memory for immediate conversational coherence. Volatile by design—holds context, not history.

2. Manomaya Kosha (The Mental Sheath) Active episodic memory with intelligent decay. Memories fade based on relevance and usage patterns learned by the RL agent, not arbitrary time windows.

3. Vijnanamaya Kosha (The Wisdom Sheath) Deep archival memory for distilled wisdom. RL-compressed summaries and core preferences that persist, preventing catastrophic forgetting.

🎭 Viveka Layer - The Autonomous Conscience

The moral compass that determines what deserves memory:

• Autonomous Importance Scoring - Evaluates emotional significance, goal alignment, and surprise value
• Dharma Alignment - Ethical guardrails against biased or harmful content storage
• Personalized Learning - Adapts importance criteria to individual user patterns over time

🚀 Quick Start

Zero configuration required. Vidurai's RL agent handles optimization autonomously:

pip install vidurai

from vidurai import Vidurai

# Awaken Vidurai with autonomous learning enabled
memory = Vidurai()

# Simply tell Vidurai what happened - it learns what matters
memory.remember(
    session_id="user123",
    content="My name is Alice. I'm a vegetarian planning a trip to Japan."
)
memory.remember(
    session_id="user123",
    content="Hmm, let me think about the dates."
)

# Later, recall only what's relevant - RL agent compressed optimally
relevant_context = memory.recall(
    session_id="user123",
    query="What are some good food options there?"
)

# Returns: "User is Alice. User is a vegetarian. User is planning a trip to Japan."
# Trivial filler automatically forgotten through learned compression strategy

Advanced: Enable RL Learning Mode

from vidurai.core.vismriti import VismritiRLAgent

# Initialize with custom learning parameters
rl_agent = VismritiRLAgent(
    learning_rate=0.1,
    discount_factor=0.95,
    exploration_rate=0.1
)

# Train on your specific use case
rl_agent.train(episodes=1000, verbose=True)

# Use with Vidurai
memory = Vidurai(compression_agent=rl_agent)

---

⚠️ Known Limitations & Solutions

High-Threshold Recall (v1.5.1+)

Issue: Importance decay causes memories to drop below high thresholds over time Example: A memory with importance=0.95 drops to ~0.36 after 20 messages (0.95^20) Impact: recall(min_importance=0.7) may return fewer results than expected

Solutions:

# Option 1: Disable decay for critical applications
memory = ViduraiMemory(enable_decay=False)
critical_memories = memory.recall(min_importance=0.7)  # Now returns all HIGH memories

# Option 2: Use slower decay rate
memory = ViduraiMemory(decay_rate=0.98)  # Instead of default 0.95
# After 20 messages: 0.95 × (0.98^19) ≈ 0.64 (stays above 0.5)

# Option 3: Use lower thresholds (0.3-0.5 work reliably with decay)
important_memories = memory.recall(min_importance=0.4)

---

RL Agent Maturity

Note: The RL agent needs 50-100 episodes for reward profiles to fully differentiate behavior Expected: First 10-20 episodes show exploration behavior (epsilon=0.30) After maturity: Epsilon decays to 0.05 and learned policies become stable

Monitor learning progress:

stats = memory.get_rl_agent_stats()
print(f"Episodes: {stats['episodes']}")
print(f"Epsilon: {stats['epsilon']:.3f}")
print(f"Q-table states: {stats['q_table_size']}")

---

File Storage Scale

Limitation: File-based persistence (~/.vidurai/) optimal for <100K experiences Current: Uses JSONL for experiences, JSON for Q-table Performance: May slow down with very large experience buffers

Future: Optional SQLite backend planned for v1.6.0

Workaround for now:

# Periodically check and clean if needed
import os
exp_file = os.path.expanduser("~/.vidurai/experiences.jsonl")
if os.path.exists(exp_file) and os.path.getsize(exp_file) > 10_000_000:  # 10MB
    # Backup and truncate or implement your own cleanup
    pass

Token Optimization (Fixed in v1.5.1)

Issue in v1.5.0: Token count increased by 13.8% instead of decreasing Status: ✅ FIXED in v1.5.1 Action: Upgrade to v1.5.1+ for proper token savings

pip install --upgrade vidurai

📖 Philosophy

Vidurai is named after the wise minister from the Mahabharata, known for:

• 🗣️ Speaking truth to power - Transparent about what's remembered and why
• ⚖️ Ethical decision-making - Dharma alignment prevents harmful memory retention
• 🎯 Strategic wisdom - Learns when to forget, not just what to remember

We embed these timeless principles in modern reinforcement learning, creating AI that doesn't just remember—it remembers wisely.

"The wise do not grieve for the dead, nor for the living." — Bhagavad Gita 2.11 Similarly, wise AI does not hoard tokens—it curates meaning.
