Recommendations

For Agent 2 (DQN) GREEN LIGHT

Proceed with DQN CUDA testing

Reasons:

  • MAMBA-2 CUDA proven stable (7/7 tests)
  • GPU memory usage low (3.9GB free)
  • No thermal issues (53°C)
  • Sequential testing validated

Expected DQN Metrics:

  • Model size: ~50-150MB (smaller than MAMBA-2)
  • Memory usage: ~300-600MB
  • GPU utilization: 10-50%
  • OOM risk: Low

Command:

cargo test -p ml --test dqn_tests --release -- --nocapture

For Production Training READY

MAMBA-2 ready for 50-200 epoch training

Next Steps:

  1. Run 50-epoch validation (5-10 minutes)
  2. Verify loss reduction matches Agent 250 baseline (70.6%)
  3. If successful, proceed to 200-epoch production

Command:

cargo run -p ml --example train_mamba2_dbn --release -- --epochs 50
