Draft Agent for RIS Optimization in 6G Networks

Model Description

This is a lightweight neural network model designed for real-time Reconfigurable Intelligent Surface (RIS) phase configuration in 6G networks. The model was trained using RIS channel simulation data to predict optimal phase shifts for wireless communication optimization.

Model Details

• Architecture: 2-layer MLP with batch normalization
• Input: CSI (2048 dims) + semantic features (40 dims) = 2088 total dimensions
• Output:
  • RIS phase shifts (256 elements, range [0, 2π])
  • Confidence score ([0, 1])
  • Antenna weights (64 dims for multi-user beamforming)
• Parameters: ~700K
• Latency: 0.2 ms per inference (CPU)
• Framework: PyTorch

Training Data

• Total Samples: 5000
• Train/Val/Test Split: 70% / 15% / 15%
• Data Source: RIS channel simulation with synthetic CSI
• Features: Channel state information + geometric parameters
• Labels: Optimal RIS phase configurations for SNR maximization

Training Configuration

• Optimizer: Adam (lr=1e-3, weight_decay=1e-5)
• Scheduler: Cosine Annealing (T_max=50)
• Batch Size: 128
• Epochs: 12 (early stopping)
• Loss Function: MSE (phase prediction) + weighted BCE (confidence) + L1 regularization

Performance

• Best Validation Loss: 0.3338
• Final Training Loss: 0.3973
• Inference Latency: 0.20 ms (CPU)

Intended Use

This model is designed for:

1. Real-time RIS control in 6G mmWave systems
2. Draft agent in speculative execution pipelines
3. Low-latency decision making for URLLC applications
4. Lightweight deployment on edge devices

Limitations

• Designed for specific 6G scenario (28 GHz mmWave, 256-element RIS, 4 users)
• Trained on synthetic but realistic CSI data
• May require fine-tuning for different deployment scenarios
• Requires proper channel normalization before inference

Usage

import torch
from draft_agent import DraftAgent

# Load model
model = DraftAgent(num_ris_elements=256, num_users=4)
checkpoint = torch.load('pytorch_model.bin')
model.load_state_dict(checkpoint)
model.eval()

# Inference
with torch.no_grad():
    csi = torch.randn(batch_size, 2048)  # Channel state information
    semantic_features = torch.randn(batch_size, 40)  # Context/angles/distances
    phases, confidence, weights = model(csi, semantic_features)

# Schedule RIS phases
ris_phases = (phases + 1.0) * 3.14159  # Scale to [0, 2π]

Training Details

• Training Framework: PyTorch
• Training Device: CPU
• Training Time: ~6 seconds
• Best Epoch: 1
• Early Stopping: Triggered at epoch 12 with patience=10
