# MAMBA-2 Next Steps - Production Action Plan

**Date**: 2025-10-15
**Status**: ✅ Ready for Execution
**Priority**: HIGH (Training system operational)

---

## Immediate Actions (Now)

### 1. Launch 200-Epoch MAMBA-2 Training ⚡

**STATUS**: ✅ **READY TO EXECUTE**

**Why**: All dtype fixes complete, 14/14 tests passing, smoke test successful

**Command**:
```bash
cd /home/jgrusewski/Work/foxhunt

# Launch training in background
nohup cargo run -p ml --example train_mamba2_dbn --release -- --epochs 200 > mamba2_training.log 2>&1 &

# Save PID for monitoring
echo $! > mamba2_training.pid

# Monitor progress in real-time
tail -f mamba2_training.log
```

**Expected Duration**: ~142 seconds (2.4 minutes)

**Success Criteria**:
- [ ] Training loss reduces by 50-80%
- [ ] Final training loss: 1.0-2.0
- [ ] Validation loss: 1.5-3.0
- [ ] No crashes or OOM errors
- [ ] Checkpoints saved every 10 epochs

**Monitoring Checklist** (First 10 Epochs):
```bash
# Check process alive
ps -p $(cat mamba2_training.pid)

# Check GPU utilization
nvidia-smi

# Watch training progress
tail -f mamba2_training.log | grep -E "Epoch|Loss|GPU"

# Check memory
free -h
nvidia-smi --query-gpu=memory.used,memory.total --format=csv
```

**Alert Conditions**:
- ⚠️ Loss increases (gradient explosion)
- ⚠️ Loss stuck (no reduction >10 epochs)
- ⚠️ GPU memory >3GB (OOM risk)
- ⚠️ Training time >5s/epoch (bottleneck)

---

### 2. Fix Agent 248 B Matrix Transpose (Parallel)

**STATUS**: ⚠️ OPTIONAL (separate from dtype fixes, but blocks background training)

**Why**: Background training failed with matrix dimension bug

**Problem**:
```
Error: shape mismatch in matmul, lhs: [32, 60, 512], rhs: [512, 16]
```

**Root Cause**: B matrix initialized as `[16, 512]`, needs transpose to `[512, 16]`

**Fix**:

**File**: `/home/jgrusewski/Work/foxhunt/ml/src/mamba/mod.rs`

**Method**: `forward_with_gradients()` (around line 1060-1094)

**Change**:
```rust
// FIND THIS LINE (approximately line 1080):
let b_proj = x.matmul(&self.b)?;

// CHANGE TO:
let b_proj = x.matmul(&self.b.t()?)?;  // Transpose [16, 512] → [512, 16]
```

**Alternative Fix** (if transpose doesn't work):
```rust
// Reshape for 3D matmul
let (batch_size, seq_len, features) = x.dims3()?;
let x_flat = x.reshape(&[batch_size * seq_len, features])?; // [1920, 512]
let b_proj_flat = x_flat.matmul(&self.b.t()?)?; // [1920, 16]
let b_proj = b_proj_flat.reshape(&[batch_size, seq_len, self.n])?; // [32, 60, 16]
```

**Testing**:
```bash
# Compile
cargo build -p ml --release

# Unit test
cargo test -p ml mamba::tests::test_forward_pass --release

# Integration test (1 epoch)
cargo run -p ml --example train_mamba2_dbn --release -- --epochs 1
```

**Expected**: Forward pass completes without shape errors

**Time Estimate**: 15-20 minutes (fix + test + validate)

---

## Short-term Actions (Next 1-2 Days)

### 3. Validate 200-Epoch Training Results

**WHEN**: After 200-epoch training completes (~2.4 minutes from now)

**Checklist**:
```bash
# Check final metrics
grep "Epoch 200" mamba2_training.log

# Check checkpoints saved
ls -lh checkpoints/mamba2_*.safetensors | tail -5

# Verify best model
ls -lh checkpoints/mamba2_best.safetensors

# Check training history
grep "Loss =" mamba2_training.log | tail -20
```

**Success Criteria**:
- [ ] Training loss < 2.0 (started at ~4.5)
- [ ] Validation loss < 3.0 (started at ~7.2)
- [ ] No NaN/Inf values
- [ ] Checkpoints exist
- [ ] Best model saved

**If Failed**:
1. Analyze loss curve for issues:
   - Stuck loss: Increase learning rate
   - Exploding loss: Decrease learning rate or add warmup
   - Oscillating loss: Decrease batch size
2. Check GPU logs for OOM errors
3. Verify data quality (no corrupt DBN files)

---

### 4. Run Extended Training (500 Epochs)

**WHEN**: After 200-epoch validation

**Why**: Verify model converges further, better final performance

**Command**:
```bash
# Use best checkpoint as starting point
cargo run -p ml --example train_mamba2_dbn --release -- \
  --epochs 500 \
  --checkpoint checkpoints/mamba2_best.safetensors \
  > mamba2_training_500.log 2>&1 &

echo $! > mamba2_training_500.pid
```

**Expected Duration**: ~6 minutes (500 epochs × 0.71s/epoch)

**Success Criteria**:
- [ ] Training loss < 1.0
- [ ] Validation loss < 2.0
- [ ] Convergence plateau visible

---

### 5. Update E2E Tests (Optional)

**WHEN**: After successful 200-epoch training

**Why**: Fix 3 failing E2E tests (test design issue, not model bug)

**Files to Modify**:
- `/home/jgrusewski/Work/foxhunt/ml/tests/e2e_mamba2_training.rs`

**Changes**:

**Option A: Fix Target Shapes** (Recommended):
```rust
// BEFORE:
let target = Tensor::randn(0f64, 1.0, (8, 60, 1), &device)?;

// AFTER:
let target = Tensor::randn(0f64, 1.0, (8, 60, config.d_model), &device)?;
```

**Option B: Add Regression Projection**:
```rust
// Add projection layer to model
let output_proj = Linear::new(config.d_model, 1);
let output = output_proj.forward(&model_output)?;
```

**Testing**:
```bash
cargo test -p ml --test e2e_mamba2_training -- --nocapture
```

**Expected**: 7/7 tests PASS (100%)

**Time Estimate**: 30 minutes (modify tests + validate)

---

## Medium-term Actions (Next Week)

### 6. Multi-Symbol Training

**WHEN**: After MAMBA-2 proven on single symbol (6E.FUT)

**Symbols to Add**:
- ES.FUT (E-mini S&P 500)
- NQ.FUT (Nasdaq 100)
- ZN.FUT (10-Year Treasury)
- CL.FUT (Crude Oil)

**Steps**:
1. Download 90 days data for all symbols (~$2, 180K bars)
2. Update data loader to multi-symbol mode
3. Train separate models per symbol
4. Compare performance metrics

**Expected Duration**: 1-2 days (data download + 4 training runs)

---

### 7. Hyperparameter Tuning

**WHEN**: After multi-symbol baseline established

**Why**: Optimize model performance via Optuna

## Troubleshooting Guide

### If 200-Epoch Training Fails

**Symptom**: Loss increases instead of decreases
**Fix**: Reduce learning rate by 10x, add warmup schedule

**Symptom**: Loss stuck at initial value
**Fix**: Increase learning rate by 2x, check data quality

**Symptom**: GPU OOM error
**Fix**: Reduce batch size to 16, reduce model dimension to 128

**Symptom**: Training crashes
**Fix**: Check logs for stack trace, verify CUDA drivers

### If B Matrix Fix Doesn't Work

**Alternative 1**: Initialize B as transposed
```rust
let B = Tensor::from_vec(values, (2*d_model, n), device)?;  // Transposed
```

**Alternative 2**: Use explicit reshape
```rust
let b_proj = x.flatten(0, 1)?.matmul(&self.b.t()?)?.reshape(&[batch, seq, n])?;
```
