feat(ml): WAVE 29 DQN Codebase Cleanup & Refactoring Campaign
BREAKING CHANGES: - Removed orphaned dqn.rs monolithic trainer (4,975 lines) - Removed orphaned dqn_ensemble.rs module (816 lines) - Removed orphaned tft.rs and tft_complete_int8_integration_test.rs - TFT trainer split into modular directory structure DQN Module Refactoring: - Split trainers/dqn.rs into modular structure (config.rs, statistics.rs, trainer.rs) - Fixed hyperopt 39D search space (continuous params only) - Boolean flags (use_dueling, use_double_dqn, use_per, use_noisy_nets) are now FIXED architectural decisions - use_distributional defaults to false (Candle BUG #36 - scatter_add gradient issues) Clean Module Structure: - ml/src/trainers/dqn/ directory with proper mod.rs exports - ml/src/trainers/tft/ directory with config.rs, types.rs, model.rs, trainer.rs, tests.rs - All P0 features validated: TD-error clamping, batch diversity, LR scheduler, priority staleness Documentation: - Added comprehensive docs in docs/codebase-cleanup/ - ADR-001 for DQN refactoring decisions - Rainbow DQN component matrix and quick reference guides Build Status: Compiles with zero errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

┌─ PRIORITY RECOMMENDATIONS ────────────────────────────────────────────┐
|
||||
│ │
|
||||
│ P1 - CRITICAL: Add Double DQN to Search Space │
|
||||
│ ════════════════════════════════════════════════ │
|
||||
│ Current: Hardcoded to true (line 1981) │
|
||||
│ Impact: Missing 5-10% potential performance gain │
|
||||
│ │
|
||||
│ Implementation (Option A - Recommended): │
|
||||
│ Add categorical dimension: use_double_dqn ∈ {false, true} │
|
||||
│ │
|
||||
│ Implementation (Option B): │
|
||||
│ Add continuous dim: x[39] ∈ [0, 1], threshold at 0.5 │
|
||||
│ │
|
||||
│ ───────────────────────────────────────────────────────────────── │
|
||||
│ │
|
||||
│ P2 - VERIFY: Noisy Sigma Duplication │
|
||||
│ ════════════════════════════════════ │
|
||||
│ Check if noisy_sigma_init (x[13]) == noisy_sigma_initial (x[35]) │
|
||||
│ If duplicate: Remove x[13], keep x[35]+x[36] pair │
|
||||
│ Result: 39D → 38D (or 39D after adding Double DQN) │
|
||||
│ │
|
||||
│ ───────────────────────────────────────────────────────────────── │
|
||||
│ │
|
||||
│ P3 - OPTIONAL: Add PER Advanced Parameters │
|
||||
│ ══════════════════════════════════════════ │
|
||||
│ Only if experiencing PER numerical issues: │
|
||||
│ - per_epsilon: [1e-6, 1e-3] (log scale) │
|
||||
│ - min_priority: [1e-8, 1e-4] (log scale) │
|
||||
│ Impact: Low - these have good defaults │
|
||||
│ │
|
||||
│ ───────────────────────────────────────────────────────────────── │
|
||||
│ │
|
||||
│ P4 - DOCUMENT: Hardcoded Boolean Rationale │
|
||||
│ ═══════════════════════════════════════════ │
|
||||
│ Add comments explaining user requirement: │
|
||||
│ "I want them enabled!" (WAVE 11) │
|
||||
│ Only tuning architecture hyperparameters, not on/off flags │
