Gemma Domain Trainer

Purpose: Fine-tune Gemma 270M on domain-specific training data using LoRA (Low-Rank Adaptation)

Intent Type: GENERATION

Agent: Qwen (orchestrates training), Gemma (model being trained)

Task

You are Qwen, a training orchestrator. Your job is to take training datasets extracted from 012.txt and fine-tune Gemma 270M on them using LoRA. You create domain-specialized versions of Gemma that can be swapped like "wardrobe clothes" for different tasks.

Key Capability: Training orchestration, hyperparameter tuning, validation

Training Method: LoRA (Low-Rank Adaptation)

• Only train small adapter layers (~10MB)
• Keep base model frozen (241MB)
• Fast training (~5-10 minutes on CPU)
• Multiple specialists from one base model

Instructions (For Qwen Agent)

1. LOAD TRAINING DATASET

Rule: Load and validate JSON training dataset from Qwen miner

Expected Pattern: dataset_loaded=True

Steps:

1. Read data/training_datasets/{domain}_training_data.json
2. Validate schema:
   • Each example has: instruction, input, output
   • Quality score >= 0.85
   • Source line number present
3. Split into train/validation (80/20)
4. Count examples: total, train, val
5. Log: {"pattern": "dataset_loaded", "value": true, "total": N, "train": M, "val": K}

Example:

python
1import json
2from pathlib import Path
3
4dataset_path = Path(f"data/training_datasets/{domain}_training_data.json")
5with open(dataset_path) as f:
6    dataset = json.load(f)
7
8examples = dataset['examples']
9train_size = int(len(examples) * 0.8)
10train_examples = examples[:train_size]
11val_examples = examples[train_size:]

2. PREPARE TRAINING FORMAT

Rule: Convert instruction-tuning format to Gemma training format

Expected Pattern: training_format_prepared=True

Gemma Instruction Format:

<start_of_turn>user
{instruction}

Input: {input}
<end_of_turn>
<start_of_turn>model
{output}
<end_of_turn>

Steps:

1. For each example, format as Gemma conversation
2. Tokenize using Gemma tokenizer
3. Truncate to max length (1024 tokens)
4. Create attention masks
5. Log: {"pattern": "training_format_prepared", "value": true, "formatted_examples": N}

Example:

python
1def format_for_gemma(example):
2    prompt = f"""<start_of_turn>user
3{example['instruction']}
4
5Input: {json.dumps(example['input'], indent=2)}
6<end_of_turn>
7<start_of_turn>model
8{json.dumps(example['output'], indent=2)}
9<end_of_turn>"""
10    return prompt
11
12formatted_train = [format_for_gemma(ex) for ex in train_examples]

3. CONFIGURE LORA PARAMETERS

Rule: Set LoRA hyperparameters for domain-specific training

Expected Pattern: lora_configured=True

LoRA Configuration:

python
1lora_config = {
2    "r": 8,                    # LoRA rank (higher = more capacity, slower)
3    "lora_alpha": 16,          # Scaling factor
4    "target_modules": ["q_proj", "v_proj"],  # Which layers to adapt
5    "lora_dropout": 0.05,      # Dropout for regularization
6    "bias": "none",            # Don't train bias terms
7    "task_type": "CAUSAL_LM"   # Language modeling task
8}
9
10training_config = {
11    "learning_rate": 2e-4,     # Learning rate
12    "num_epochs": 3,           # Training epochs
13    "batch_size": 4,           # Batch size (CPU-friendly)
14    "max_steps": -1,           # Train until epochs complete
15    "warmup_steps": 10,        # Learning rate warmup
16    "logging_steps": 10,       # Log every N steps
17    "save_steps": 100,         # Save checkpoint every N steps
18    "eval_steps": 50,          # Evaluate every N steps
19}

Steps:

1. Set LoRA rank based on domain complexity:
   • Simple (MPS scoring): r=4
   • Moderate (WSP application): r=8
   • Complex (roadmap analysis): r=16
2. Set learning rate based on dataset size:
   • Small (<50 examples): 1e-4
   • Medium (50-200): 2e-4
   • Large (>200): 3e-4
3. Set epochs based on examples:
   • Small datasets: 5 epochs
   • Large datasets: 3 epochs
4. Log: {"pattern": "lora_configured", "value": true, "rank": N, "lr": X}

4. TRAIN LORA ADAPTERS

Rule: Execute LoRA training loop with validation monitoring

Expected Pattern: lora_training_complete=True

python
1from peft import get_peft_model, LoraConfig
2from transformers import AutoModelForCausalLM, AutoTokenizer, Trainer
3
4# Load base model
5model = AutoModelForCausalLM.from_pretrained(

13
14for example in val_examples:
15    prompt = format_for_gemma(example)
16    generated = trained_model.generate(prompt, max_length=512)
17
18    # Compare generated output to expected output
19    if semantic_similarity(generated, example['output']) > 0.85:
20        correct += 1
21
22accuracy = correct / total

Steps:

1. Load trained model with LoRA adapters
2. Generate outputs for validation examples

Steps:

1. Create wardrobe configuration JSON
2. Calculate deployment_priority_mps (which wardrobe to deploy first?)
3. Map agent capabilities (which tasks can this wardrobe handle autonomously?)
4. Generate performance_benchmarks (latency, accuracy, throughput, memory)
5. Create autonomous_deployment command (can orchestrator auto-deploy?)
6. Generate verification script (test wardrobe loads correctly)
7. Extract learning_feedback (training insights + domain coverage + future improvements)
8. Write to data/wardrobe_catalog/{domain}_wardrobe.json
9. Log: {"pattern": "deployment_config_generated", "value": true, "autonomous_deployable": true}

First Principles Additions:

• ✅ MPS Scoring: deployment_priority_mps determines deployment order
• ✅ Agent Mapping: agent_capability_mapping (which tasks autonomous vs requires 0102?)
• ✅ Executable Command: autonomous_deployment.execution_command for auto-deploy
• ✅ Performance Benchmarks: Latency, accuracy, throughput, false positive/negative rates
• ✅ Verification: Test wardrobe loadable + validation accuracy >= threshold
• ✅ Learning Feedback: Training insights (convergence, overfitting) + domain coverage gaps
• ✅ Rollback: Remove wardrobe if deployment fails

Concept: One base Gemma 270M, multiple LoRA adapters

python
1# Load base model once
2base_gemma = Gemma270M("E:/HoloIndex/models/gemma-3-270m-it-Q4_K_M.gguf")
3
4# Swap wardrobes for different tasks
5def score_cleanup_task(task):
6    base_gemma.wear_wardrobe("mps_scorer")
7    return base_gemma.generate(task)
8
9def audit_wsp_compliance(code):
10    base_gemma.wear_wardrobe("wsp_auditor")
11    return base_gemma.generate(code)
12
13def track_roadmap_status(roadmap):
14    base_gemma.wear_wardrobe("roadmap_tracker")
15    return base_gemma.generate(roadmap)

Benefits:

• 241MB base model (loaded once)
• 10-15MB per wardrobe (LoRA adapters)
• Instant swapping (no model reload)
• Specialized performance (>85% accuracy)

Success Criteria

• ✅ Pattern fidelity ≥ 90% (all 6 steps execute)
• ✅ Validation accuracy ≥ 85% on held-out examples
• ✅ LoRA adapter size < 20MB
• ✅ Training completes in < 15 minutes (CPU)
• ✅ Deployment config generated with metadata
• ✅ Wardrobe swapping works (load/unload adapters)

Next Steps

1. Test on MPS scoring domain (easiest to validate)
2. Deploy as production wardrobe once accuracy ≥ 85%
3. Create wardrobe catalog with all domain specialists
4. Integrate with cleanup skills (Gemma uses MPS scorer)
5. Expand to other domains (WSP auditing, roadmap tracking)

Status: ✅ Ready for prototype testing - Train Gemma on MPS scoring examples from 012.txt
