🚀 Quick Start

Example 1: Granular Arithmetic

from grant.core.granule import make_granule

# Create granules with uncertainty
g1 = make_granule([1.0, 2.0, 3.0], confidence=0.9)
g2 = make_granule([0.5, 0.5, 0.5], confidence=0.8)

# Granular addition (uncertainty propagates)
g3 = g1 + g2
print(f"Result: {g3.value}, Confidence: {g3.confidence}")
# Result: [1.5 2.5 3.5], Confidence: 0.8

# Fusion (combines contexts)
g4 = g1.fuse(g2)
print(f"Fused: {g4.value.shape}, Confidence: {g4.confidence}")
# Fused: (6,), Confidence: 0.72

Example 2: Sheaf-Theoretic Attention

from grant.core.sheaf_attention import SheafTransformer
import torch

# Create SheafFormer model
model = SheafTransformer(
    vocab_size=10000,
    d_model=256,
    n_layers=4,
    n_heads=8,
    temperature=0.5  # Controls cocycle sparsity
)

# Forward pass
input_ids = torch.randint(0, 10000, (2, 128))
output = model(input_ids)
print(f"Output shape: {output.shape}")
# Output shape: torch.Size([2, 128, 10000])

Example 3: Autonomous Research with AutoCognition

from grant.workflows.auto_cognition import AutoCognitionEngine, ResearchGoal
from pathlib import Path

# Initialize engine
engine = AutoCognitionEngine(storage_dir=Path("./grant_data"))

# Define research goal
goal = ResearchGoal(
    description="Design a low-latency attention mechanism for edge devices",
    constraints={
        "latency_ms": 10,
        "memory_mb": 1
    },
    metrics=["accuracy", "latency", "memory"],
    context={"team_size": 3, "timeline": "2 weeks"}
)

# Let AI investigate autonomously
solution = engine.investigate(goal)

# Access results
print(solution.documentation)
print(f"Parameters: {solution.performance['parameters']:,}")

# Save artifact
engine.generate_artifact(solution, Path("./my_model.py"))

📖 Core Concepts

1. Granular Arithmetic

Mathematical Definition: A granule is a tuple g = (x, μ, τ) where:

• x ∈ X: Value (vector, scalar, categorical, etc.)
• μ ∈ [0,1]: Epistemic confidence
• τ ∈ T: Type tag

Key Theorem (Uncertainty Propagation): For Lipschitz-continuous function f with constant L:

g' = f(g) ⟹ μ' = μ · exp(-L · r)

where r = 1 - μ is the uncertainty radius.

Operations:

• Addition g₁ ⊕ g₂: Type-aware element-wise addition
• Fusion g₁ ⊗ g₂: Context-preserving combination
• Projection g ↓_P: Uncertainty-tracked transformation

2. Sheaf-Theoretic Attention

Mathematical Foundation: Attention as cohomological optimization over presheaves of features.

Theorem (Cocycle Attention): Optimal attention weights minimizing informational tension:

α_ij = exp(-D_KL(f_j || f_i) / λ) / Z_i

This recovers softmax attention as a special case!

Architecture Components:

• Poset: Hierarchical structure (tokens → sentences → documents)
• Presheaf: Feature spaces at each level
• Cocycle: Attention satisfying global consistency
• Restriction Maps: Cross-level information flow

3. Self-Evolving Prompt Architecture (SEPA)

Workflow:

User Goal → Template Selection → Solution Generation
    ↓                                      ↓
Outcome Tracking ← Metrics ← Execution ←──┘
    ↓
Learning Extraction → Template Evolution → Update Library

Learning Mechanisms:

• Success pattern extraction
• Failure pattern avoidance
• Constraint inference
• Multi-armed bandit selection

🧪 Examples

Example 1: Custom Attention Mechanism

from grant.core.sheaf_attention import CocycleAttention
import torch.nn as nn

class MyTransformer(nn.Module):
    def __init__(self, d_model):
        super().__init__()
        self.attention = CocycleAttention(
            d_model=d_model,
            temperature=0.8,
            use_kl=True  # Use actual KL divergence
        )
        self.ffn = nn.Linear(d_model, d_model)
    
    def forward(self, x):
        attn_out, weights = self.attention(x, x, x)
        return self.ffn(attn_out)

Example 2: Uncertainty-Aware Training

from grant.core.granule import GranuleSpace, from_numpy
import numpy as np

# Create dataset with per-sample confidence
data = np.random.randn(100, 10)
confidences = np.random.rand(100)  # Vary by sample quality

# Convert to granule space
granule_data = from_numpy(data, confidences)

# Aggregate with confidence weighting
aggregated = granule_data.aggregate(method="mean")
print(f"Weighted mean confidence: {aggregated.confidence:.3f}")

Example 3: Template Evolution

from grant.workflows.sepa import SEPAEngine, PromptTemplate
from pathlib import Path

# Initialize SEPA
sepa = SEPAEngine(storage_dir=Path("./sepa_storage"))

# Create template
template = PromptTemplate(
    name="optimization_v1",
    content="Optimize {component} for {metric}",
    variables=["component", "metric"]
)
sepa.register_template(template)

# Simulate executions
for i in range(10):
    outcome = sepa.execute_and_learn(
        request=f"Optimize model latency #{i}",
        template_id=template.template_id,
        solution=f"Solution {i}",
        metrics={"latency": 0.7 + np.random.rand() * 0.3},
        success=True,
        lessons=["Sparsity helps", "Quantization effective"]
    )

# Template automatically evolves!
print(sepa.generate_report())
