# Wave 9 Agent 19: Training Example Smoke Test Report
|
||||
|
||||
**Agent**: Wave 9 Agent 19
|
||||
**Mission**: Quick smoke test each training example compiles and can extract features
|
||||
**Status**: ⚠️ **COMPILATION SUCCESS, RUNTIME FAILURE DETECTED**
|
||||
**Date**: 2025-10-20
|
||||
**Duration**: 25 minutes
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
All 4 training examples compile successfully with only minor warnings (unused dependencies, unused variables). However, **DQN runtime smoke test failed** with an **infinity value at feature index 45** during feature extraction. This is a **data quality issue**, not a compilation problem.
|
||||
|
||||
### Key Findings
|
||||
|
||||
1. ✅ **All 4 examples compile cleanly** (train_dqn, train_ppo, train_mamba2_dbn, train_tft_dbn)
|
||||
2. ✅ **225-feature configuration confirmed** across all models
|
||||
3. ⚠️ **Runtime failure**: Infinity at feature index 45 (rolling max)
|
||||
4. ⚠️ **Root cause**: `compute_max()` returns `f64::NEG_INFINITY` when bars.len() < period
|
||||
5. ✅ **Data loading operational**: 665,483 OHLCV bars loaded from 360 DBN files
|
||||

## 2. DQN Smoke Test (1 Epoch)
|
||||
|
||||
### Test Configuration
|
||||
```bash
|
||||
cargo run -p ml --example train_dqn --release -- \
|
||||
--epochs 1 \
|
||||
--batch-size 32 \
|
||||
--output-dir /tmp/dqn_smoke_test
|
||||
```
|
||||
|
||||
### Data Loading Results
|
||||
- **DBN Files Loaded**: 360 files
|
||||
- **Total OHLCV Bars**: 665,483 bars
|
||||
- **Assets**: ES.FUT, NQ.FUT, 6E.FUT, ZN.FUT
|
||||
- **Time Range**: January-April 2024
|
||||
- **Data Quality**: All files loaded successfully (0 errors)
|
||||
|
||||
### Feature Extraction Failure
|
||||
|
||||
**Error**:
|
||||
```
|
||||
Error: Training failed
|
||||
|
||||
Caused by:
|
||||
Invalid feature at index 45: inf
|
||||
|
||||
Stack backtrace:
|
||||
0: anyhow::error::<impl anyhow::Error>::msg
|
||||
1: ml::features::extraction::FeatureExtractor::validate_features
|
||||
2: ml::features::extraction::FeatureExtractor::extract_current_features
|
||||
3: ml::trainers::dqn::DQNTrainer::train::{{closure}}
|
||||
```
|
||||
|
||||
**Root Cause**:
|
||||
|
||||
Feature index 45 corresponds to the **rolling max** calculation in statistical features. The issue occurs in `/home/jgrusewski/Work/foxhunt/ml/src/features/extraction.rs`:
|
||||
|
||||
```rust
|
||||
// Line 991-998: compute_max returns f64::NEG_INFINITY when no bars
|
||||
fn compute_max(&self, period: usize) -> f64 {
|
||||
let start = self.bars.len().saturating_sub(period);
|
||||
self.bars
|
||||
.iter()
|
||||
.skip(start)
|
||||
.map(|b| b.close)
|
||||
.fold(f64::NEG_INFINITY, f64::max) // ← Returns NEG_INFINITY if empty
|
||||
}
|
||||
|
||||
// Line 909: Percentile rank calculation produces infinity
|
||||
out[idx] = safe_clip((bar.close - min) / (max - min + 1e-8), 0.0, 1.0);
|
||||
// ↑
|
||||
// When max = NEG_INFINITY, this produces inf
|
||||
```
|
||||
|
||||
**Specific Failure Case**:
|
||||
- **Feature 45**: Rolling max (20-period) for period=50
|
||||
- **Condition**: `self.bars.len() < 50` during warmup phase
|
||||
- **Expected**: Should return safe default (0.0 or current close price)
|
||||
- **Actual**: Returns `f64::NEG_INFINITY`, causing division by `(NEG_INFINITY - min + 1e-8)` → infinity
|

## 3. 225-Feature Configuration Verification
|
||||
|
||||
### DQN Trainer (ml/src/trainers/dqn.rs)
|
||||
```rust
|
||||
// Line 135: Full feature set configured
|
||||
let config = WorkingDQNConfig {
|
||||
state_dim: 225, // Full feature set (Wave C + Wave D regime detection)
|
||||
num_actions: 3, // Buy, Sell, Hold
|
||||
hidden_dims: vec![128, 64, 32],
|
||||
...
|
||||
};
|
||||
|
||||
// Line 496-502: Feature extraction confirmed
|
||||
info!("Extracting full 225-feature vectors from OHLCV bars (Wave C + Wave D)...");
|
||||
let feature_vectors = self.extract_full_features(&all_ohlcv_bars)?;
|
||||
info!(
|
||||
"Extracted {} feature vectors (225 dimensions each, Wave C + Wave D)",
|
||||
feature_vectors.len()
|
||||
);
|
||||
```
|
||||
|
||||
### Feature Vector Type
|
||||
```rust
|
||||
// Line 26: Type alias for 225-dim features
|
||||
type FeatureVector225 = [f64; 225];
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 4. Recommended Fixes
|
||||
|
||||
### Priority 1: Fix compute_max/compute_min Edge Case (5 min)
|
||||
|
||||
**File**: `/home/jgrusewski/Work/foxhunt/ml/src/features/extraction.rs`
|
||||
|
||||
**Fix**:
|
||||
```rust
|
||||
fn compute_max(&self, period: usize) -> f64 {
|
||||
let start = self.bars.len().saturating_sub(period);
|
||||
let max = self.bars
|
||||
.iter()
|
||||
.skip(start)
|
||||
.map(|b| b.close)
|
||||
.fold(f64::NEG_INFINITY, f64::max);
|
||||
|
||||
// Return safe default if no valid bars
|
||||
if max.is_finite() {
|
||||
max
|
||||
} else {
|
||||
// Use current close price as fallback
|
||||
self.bars.back().map(|b| b.close).unwrap_or(0.0)
|
||||
}
|
||||
}
|
||||
|
||||
fn compute_min(&self, period: usize) -> f64 {
|
||||
let start = self.bars.len().saturating_sub(period);
|
||||
let min = self.bars
|
||||
.iter()
|
||||
.skip(start)
|
||||
.map(|b| b.close)
|
||||
.fold(f64::INFINITY, f64::min);
|
||||
|
||||
// Return safe default if no valid bars
|
||||
if min.is_finite() {
|
||||
min
|
||||
} else {
|
||||
// Use current close price as fallback
|
||||
self.bars.back().map(|b| b.close).unwrap_or(0.0)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Priority 2: Add Early Validation in extract_statistical_features (3 min)
|
||||
|
||||
**File**: `/home/jgrusewski/Work/foxhunt/ml/src/features/extraction.rs`
|
||||
|
||||
**Fix**:
|
||||
```rust
|
||||
fn extract_statistical_features(&self, out: &mut [f64]) -> Result<()> {
|
||||
let bar = self.bars.back().context("No current bar")?;
|
||||
let mut idx = 0;
|
||||
|
||||
// Rolling statistics for multiple periods (16): Z-score and percentile rank only
|
||||
for period in [5, 10, 20, 50] {
|
||||
if self.bars.len() >= period {
|
||||
let mean = self.compute_sma(period);
|
||||
let std = self.compute_std(period);
|
||||
let min = self.compute_min(period);
|
||||
let max = self.compute_max(period);
|
||||
|
||||
// Validate min/max before using them
|
||||
if !min.is_finite() || !max.is_finite() || (max - min).abs() < 1e-8 {
|
||||
// Skip this period if invalid
|
||||
out[idx] = 0.0;
|
||||
out[idx + 1] = 0.5; // Neutral percentile
|
||||
idx += 2;
|
||||
continue;
|
||||
}
|
||||
|
||||
// Z-score: How many standard deviations from mean
|
||||
out[idx] = safe_clip((bar.close - mean) / (std + 1e-8), -3.0, 3.0);
|
||||
idx += 1;
|
||||
|
||||
// Percentile rank: Position within min-max range
|
||||
out[idx] = safe_clip((bar.close - min) / (max - min + 1e-8), 0.0, 1.0);
|
||||
idx += 1;
|
||||
} else {
|
||||
out[idx] = 0.0;
|
||||
out[idx + 1] = 0.5;
|
||||
idx += 2;
|
||||
}
|
||||
}
|
||||
|
||||
// ... rest of function
|
||||
}
|
||||
```

|
||||
|
||||
## 7. Next Steps
|
||||
|
||||
### Immediate (Agent 20)
|
||||
1. ✅ **Fix compute_max/compute_min edge case** (5 min)
|
||||
2. ✅ **Add validation in extract_statistical_features** (3 min)
|
||||
3. ✅ **Re-run DQN 1-epoch smoke test** (2 min)
|
||||
4. ✅ **Verify feature extraction completes** (1 min)
|
||||
|
||||
### Follow-up (Agent 21+)
|
||||
1. Run full 10-epoch training test (DQN)
|
||||
2. Smoke test PPO, MAMBA-2, TFT (1 epoch each)
|
||||
3. Profile feature extraction performance (<1ms target)
|
||||
4. Run integration tests with Trading Agent
|
||||
|
||||
---
|
||||
|
||||
## 8. Confidence & Risk Assessment
|
||||
|
||||
### Confidence: 95%
|
||||
- ✅ All 4 examples compile cleanly
|
||||
- ✅ 225-feature configuration verified across all models
|
||||
- ✅ Data loading operational (665K+ bars)
|
||||
- ⚠️ Runtime issue identified and root cause known
|
||||
- ⚠️ Fix is straightforward (8 minutes estimated)
|
||||
|
||||
### Risk Assessment: **LOW**
|
||||
- **Impact**: Training examples fail during warmup phase only
|
||||
- **Scope**: 2 functions in extraction.rs (compute_max, compute_min)
|
||||
- **Mitigation**: Simple edge case handling (finite value checks)
|
||||
- **Testing**: Re-run smoke test after fix (2 min)
|
||||
|
||||
---
|
||||
|
||||
## 9. Conclusion
|
||||
|
||||
**Deliverable**:
|
||||
- ✅ **Compilation status for all 4 examples**: 4/4 PASS
|
||||
- ⚠️ **Smoke test result**: FAIL (infinity at feature 45)
|
||||
- ✅ **Confirmation that 225 features are being used**: VERIFIED
|
||||
|
||||
**Status**: **⚠️ PARTIAL SUCCESS**
|
||||
|
||||
All training examples compile successfully, and 225-feature configuration is verified. However, a runtime edge case in `compute_max()`/`compute_min()` causes feature extraction to fail during the warmup phase. The fix is straightforward and estimated at 8 minutes total implementation time.
|
||||
|
||||
**Recommendation**: **Proceed to Agent 20** to implement the fix and re-run smoke test.
