Overview

The Lean Agentic Learning System represents a new paradigm in machine learning that integrates:

1. Lean Theorem Proving - Mathematical rigor and formal verification
2. Agentic AI - Autonomous decision-making with goal-oriented behavior
3. Stream Learning - Real-time online adaptation from continuous data
4. Knowledge Evolution - Dynamic knowledge graphs that grow with experience

Key Features

• ✅ Formal Verification - Every action can be proven safe and correct
• 🎯 Autonomous Agents - Self-directed learning and decision-making
• 📊 Real-Time Adaptation - Learn from streaming data without batch processing
• 🧠 Knowledge Graphs - Build and evolve structured knowledge dynamically
• ⚡ Low Latency - Process and learn from streams in real-time
• 🔒 Type Safe - Full Rust implementation with TypeScript client
• 🌐 Multi-Language - Rust core with TypeScript, Python bindings

Core Innovations

1. Lean Formal Reasoning

Inspired by the Lean theorem prover, our system provides:

use midstream::{FormalReasoner, Theorem, Proof};

let mut reasoner = FormalReasoner::new();

// Add axioms
reasoner.add_axiom(Theorem {
    statement: "Actions must not cause harm".to_string(),
    confidence: 1.0,
    tags: vec!["safety".to_string()],
    ..Default::default()
});

// Verify actions before execution
let proof = reasoner.verify_action(&action, &context).await?;

if proof.is_valid() {
    // Safe to execute
    execute_action(&action).await?;
}

Benefits:

• Provably safe agent behavior
• Mathematical guarantees on action correctness
• Explainable decision-making
• Verified knowledge accumulation

2. Agentic Loop (Plan-Act-Observe-Learn)

Our autonomous agent loop enables self-directed learning:

│                                     │

│     └─ Collect outcomes             │
│        └─ Measure actual reward     │
│                                     │
│  4. LEARN                           │
│     └─ Update policies              │
│        └─ Refine knowledge graph    │
│           └─ Adapt model weights    │
│                                     │
└─────────────────────────────────────┘

Example:

use midstream::{AgenticLoop, LeanAgenticConfig, Context};

let mut agent = AgenticLoop::new(config);
let context = Context::new("session_001".to_string());

// PLAN
let plan = agent.plan(&context, "Get weather for Tokyo").await?;

// ACT
let action = agent.select_action(&plan).await?;
let observation = agent.execute(&action).await?;

// OBSERVE & LEARN
let reward = agent.compute_reward(&observation).await?;
agent.learn(LearningSignal { action, observation, reward }).await?;

3. Stream Learning

Unlike traditional batch learning, our system learns continuously:

use midstream::{StreamLearner, AdaptationStrategy};

let mut learner = StreamLearner::new(0.01); // Learning rate

// Process stream in real-time
for chunk in stream {
    let entities = kg.extract_entities(&chunk).await?;
    kg.update(entities).await?;

    let action = agent.select_action(&context).await?;
    let reward = execute_and_measure(&action).await?;

    // Online learning - updates happen immediately
    learner.update(&action, reward, &chunk).await?;
}

Adaptation Strategies:

1. Immediate - Update after every experience (fastest adaptation)
2. Batched - Update after N experiences (stable learning)
3. Experience Replay - Randomly replay past experiences (better generalization)

4. Dynamic Knowledge Graph

Knowledge evolves as the system learns:

use midstream::{KnowledgeGraph, Entity, Relation, EntityType};

let mut kg = KnowledgeGraph::new();

// Extract entities from streaming text
let entities = kg.extract_entities("Alice works at Google").await?;

// Entities found: ["Alice" (Person), "Google" (Organization)]

// Update graph
kg.update(entities).await?;

// Add relations
kg.add_relation(Relation {
    subject: "alice_id".to_string(),
    predicate: "works_at".to_string(),
    object: "google_id".to_string(),
    confidence: 0.9,
    ..Default::default()
});

// Query related entities
let related = kg.find_related("alice_id", max_depth: 2);

// Time-based facts
kg.add_temporal_fact(TemporalFact {
    fact: "Weather is sunny".to_string(),
    valid_from: now,
    valid_until: Some(now + 3600),
    confidence: 0.9,
});
