🧹 BGE Validation System Cleanup - Complete Summary

📋 What Was Done

I conducted a comprehensive audit and cleanup of your BGE validation/evaluation system to eliminate redundancy, confusion, and outdated code. Here's the complete breakdown:

---

❌ Files REMOVED (Redundant/Confusing)

Deleted Scripts:

1. scripts/validate_m3.py ❌

   • Why removed: Simple validation functionality duplicated in quick_validation.py
   • Replaced by: python scripts/validate.py quick --retriever_model ...

2. scripts/validate_reranker.py ❌

   • Why removed: Simple validation functionality duplicated in quick_validation.py
   • Replaced by: python scripts/validate.py quick --reranker_model ...

3. scripts/evaluate.py ❌

   • Why removed: Heavy overlap with comprehensive_validation.py, causing confusion
   • Replaced by: python scripts/validate.py comprehensive ...

4. scripts/compare_retriever.py ❌

   • Why removed: Separate scripts for each model type was confusing
   • Replaced by: python scripts/compare_models.py --model_type retriever ...

5. scripts/compare_reranker.py ❌

   • Why removed: Separate scripts for each model type was confusing
   • Replaced by: python scripts/compare_models.py --model_type reranker ...

✅ New Streamlined System

NEW Core Scripts:

1. scripts/validate.py 🌟 [NEW - MAIN ENTRY POINT]

   • Purpose: Single command interface for ALL validation needs
   • Modes: quick, comprehensive, compare, benchmark, all
   • Usage: python scripts/validate.py [mode] --retriever_model ... --reranker_model ...

2. scripts/compare_models.py 🌟 [NEW - UNIFIED COMPARISON]

   • Purpose: Compare retriever/reranker/both models against baselines
   • Usage: python scripts/compare_models.py --model_type [retriever|reranker|both] ...

Enhanced Existing Scripts:

3. scripts/quick_validation.py ✅ [KEPT & IMPROVED]

   • Purpose: Fast 5-minute validation checks
   • Integration: Called by validate.py quick

4. scripts/comprehensive_validation.py ✅ [KEPT & IMPROVED]

   • Purpose: Detailed 30-minute validation with metrics
   • Integration: Called by validate.py comprehensive

5. scripts/benchmark.py ✅ [KEPT]

   • Purpose: Performance benchmarking (throughput, latency, memory)
   • Integration: Called by validate.py benchmark

6. scripts/validation_utils.py ✅ [KEPT]

   • Purpose: Utility functions for validation

7. scripts/run_validation_suite.py ✅ [KEPT & UPDATED]

   • Purpose: Advanced validation orchestration
   • Updates: References to new comparison scripts

Core Evaluation Modules (Unchanged):

8. evaluation/evaluator.py ✅ [KEPT]
9. evaluation/metrics.py ✅ [KEPT]

🎯 Before vs After Comparison

❌ OLD CONFUSING SYSTEM:

# Which script do I use? What's the difference?
python scripts/validate_m3.py              # Simple validation?
python scripts/validate_reranker.py        # Simple validation?
python scripts/evaluate.py                 # Comprehensive evaluation?
python scripts/compare_retriever.py        # Compare retriever?
python scripts/compare_reranker.py         # Compare reranker?
python scripts/quick_validation.py         # Quick validation?
python scripts/comprehensive_validation.py # Also comprehensive?
python scripts/benchmark.py               # Performance?

✅ NEW STREAMLINED SYSTEM:

# ONE CLEAR COMMAND FOR EVERYTHING:
python scripts/validate.py quick           # Fast check (5 min)
python scripts/validate.py compare         # Compare vs baseline (15 min)  
python scripts/validate.py comprehensive   # Detailed evaluation (30 min)
python scripts/validate.py benchmark       # Performance test (10 min)
python scripts/validate.py all             # Everything (1 hour)

# Advanced usage:
python scripts/compare_models.py --model_type both  # Unified comparison
python scripts/benchmark.py --model_type retriever  # Direct benchmarking

🚀 How to Use the New System

Quick Start (Most Common Use Cases):

# 1. After training - Quick sanity check (5 minutes)
python scripts/validate.py quick \
    --retriever_model ./output/bge_m3_三国演义/final_model \
    --reranker_model ./output/bge_reranker_三国演义/final_model

# 2. Compare vs baseline - How much did I improve? (15 minutes)  
python scripts/validate.py compare \
    --retriever_model ./output/bge_m3_三国演义/final_model \
    --reranker_model ./output/bge_reranker_三国演义/final_model \
    --retriever_data "data/datasets/三国演义/splits/m3_test.jsonl" \
    --reranker_data "data/datasets/三国演义/splits/reranker_test.jsonl"

# 3. Production readiness - Complete validation (1 hour)
python scripts/validate.py all \
    --retriever_model ./output/bge_m3_三国演义/final_model \
    --reranker_model ./output/bge_reranker_三国演义/final_model \
    --test_data_dir "data/datasets/三国演义/splits"
