# Unicosys Hypergraph Knowledge Model

A trainable knowledge graph embedding model encoding the unified evidence
hypergraph for Case 2025-137857.

## Model Description

This model encodes a **unified hypergraph** linking financial transactions,
email communications, legal evidence, and entity relationships into a
single trainable knowledge representation.

### Architecture

| Hidden Dimension | 256 |
| Text Encoder | 2-layer Transformer, 4 heads |
| Graph Attention | 2-layer GAT, 4 heads |
| Link Predictor | 2-layer MLP with margin ranking loss |
| Total Parameters | **36,023,681** |

### Knowledge Graph Statistics

| Metric | Count |
|---|---|
| Total Nodes | 272,683 |
| Total Edges | 14,816 |
| Cross-Links | 3,976 |
| Entities | 16 |
| Emails | 199,553 |
| Financial Documents | 17,036 |
| Timeline Events | 54,346 |

## Training

The model can be fine-tuned on link prediction tasks:

```python
from model.unicosys_model import UnicosysHypergraphModel, UnicosysConfig

model = UnicosysHypergraphModel.from_pretrained("hyperholmes/unicosys-hypergraph")
# ... prepare training data ...
# model.forward(node_ids, node_type_ids, subsystem_ids, edge_index, edge_type_ids,
#               pos_edge_index=pos, neg_edge_index=neg, labels=labels)
```
