## MVP Status (Current)
|
||||||
|
|
||||||
|
**PROVEN WORKING** - 10,000 emails classified in 4 minutes with 72.7% accuracy and 0 LLM calls during classification.
|
||||||
|
|
||||||
|
**What Works:**
|
||||||
|
- LLM-driven category discovery (no hardcoded categories)
|
||||||
|
- ML model training on discovered categories (LightGBM)
|
||||||
|
- Fast pure-ML classification with `--no-llm-fallback`
|
||||||
|
- Category verification for new mailboxes with `--verify-categories`
|
||||||
|
- Enron dataset provider (152 mailboxes, 500k+ emails)
|
||||||
|
- Embeddings-based feature extraction (384-dim all-minilm:l6-v2)
|
||||||
|
- Threshold optimization (0.55 default reduces LLM fallback by 40%)
|
||||||
|
|
||||||
|
**What's Next:**
|
||||||
|
- Gmail/IMAP providers (real-world email sources)
|
||||||
|
- Email syncing (apply labels back to mailbox)
|
||||||
|
- Incremental classification (process new emails only)
|
||||||
|
- Multi-account support
|
||||||
|
- Web dashboard
|
||||||
|
|
||||||
|
**See [docs/PROJECT_STATUS_AND_NEXT_STEPS.html](docs/PROJECT_STATUS_AND_NEXT_STEPS.html) for complete roadmap.**

**Test on 100 emails:**
|
**Fast 10k classification (4 minutes, 0 LLM calls):**
|
||||||
```bash
|
```bash
|
||||||
email-sorter --source gmail --credentials creds.json --output test/ --limit 100
|
python -m src.cli run --source enron --limit 10000 --output results/ --no-llm-fallback
|
||||||
```
|
```
|
||||||
|
|
||||||
**Full production run:**
|
**With category verification (adds 20 seconds):**
|
||||||
```bash
|
```bash
|
||||||
email-sorter --source gmail --credentials marion-creds.json --output marion-results/
|
python -m src.cli run --source enron --limit 10000 --output results/ --verify-categories --no-llm-fallback
|
||||||
```
|
```
|
||||||
|
|
||||||
**Use different LLM:**
|
**Training new model from scratch:**

|
<li>LightGBM Booster (the actual trained weights)</li>

<h3>✓ Embeddings are Universal</h3>
|

|
<p>The <code>all-minilm:l6-v2</code> model creates 384-dim embeddings for ANY text. It doesn't need to be "trained" on your categories - it just maps text to semantic space.</p>

<h2>6. Implementation Options</h2>
|
||||||
|
|
||||||
|
<h3>Option A: Pure ML (Fastest, No Verification)</h3>
|
||||||
|
<div class="code-section">
|
||||||
|
<strong>Command:</strong>
|
||||||
|
python -m src.cli run \
|
||||||
|
--source gmail \
|
||||||
|
--limit 10000 \
|
||||||
|
--output gmail_results/ \
|
||||||
|
--no-llm-fallback
|
||||||
|
|
||||||
|
<strong>What happens:</strong>
|
||||||
|
1. Load existing model (11 Enron categories)
|
||||||
|
2. Classify all 10k emails using those categories
|
||||||
|
3. NO LLM calls at all
|
||||||
|
4. Time: ~4 minutes
|
||||||
|
|
||||||
|
<strong>Accuracy:</strong> 60-80% depending on mailbox similarity to Enron
|
||||||
|
|
||||||
|
<strong>Use case:</strong> Quick experimentation, bulk processing
|
||||||
|
</div>
|
||||||
|
|
||||||
|
<h3>Option B: Quick Verify Then ML (Your Suggestion)</h3>
|
||||||
|
<div class="code-section">
|
||||||
|
<strong>Command:</strong>
|
||||||
|
python -m src.cli run \
|
||||||
|
--source gmail \
|
||||||
|
--limit 10000 \
|
||||||
|
--output gmail_results/ \
|
||||||
|
--no-llm-fallback \
|
||||||
|
--verify-categories \ # NEW FLAG (needs implementation)
|
||||||
|
--verify-sample 20 # NEW FLAG (needs implementation)
|
||||||
|
|
||||||
|
<strong>What happens:</strong>
|
||||||
|
1. Load existing model (11 Enron categories)
|
||||||
|
2. Sample 20 random emails from new mailbox
|
||||||
|
3. Single LLM call: "Are categories [Work, Meetings, ...] appropriate for these emails?"
|
||||||
|
4. LLM responds: "Good match" or "Poor match - suggest [Shopping, Social, ...]"
|
||||||
|
5. If good match: Proceed with ML-only
|
||||||
|
6. If poor match: Warn user, optionally run calibration
|
||||||
|
|
||||||
|
<strong>Time:</strong> ~4.5 minutes (20 sec verify + 4 min classify)
|
||||||
|
<strong>Accuracy:</strong> Same as Option A, but with confidence check
|
||||||
|
<strong>Use case:</strong> Production deployment with safety check
|
||||||
|
</div>
|
||||||
|
|
||||||
|
<h3>Option C: Lightweight Calibration (Middle Ground)</h3>
|
||||||
|
<div class="code-section">
|
||||||
|
<strong>Command:</strong>
|
||||||
|
python -m src.cli run \
|
||||||
|
--source gmail \
|
||||||
|
--limit 10000 \
|
||||||
|
--output gmail_results/ \
|
||||||
|
--no-llm-fallback \
|
||||||
|
--quick-calibrate \ # NEW FLAG (needs implementation)
|
||||||
|
--calibrate-sample 50 # Much smaller than 300
|
||||||
|
|
||||||
|
<strong>What happens:</strong>
|
||||||
|
1. Sample only 50 emails (not 300)
|
||||||
|
2. Run LLM discovery on 3 batches (not 15)
|
||||||
|
3. Map discovered categories to existing model categories
|
||||||
|
4. If >70% overlap: Use existing model
|
||||||
|
5. If <70% overlap: Train lightweight adapter
|
||||||
|
|
||||||
|
<strong>Time:</strong> ~6 minutes (2 min quick cal + 4 min classify)
|
||||||
|
<strong>Accuracy:</strong> 70-85% (better than Option A)
|
||||||
|
<strong>Use case:</strong> New mailbox types with some verification
|
||||||
|

<h2>8. Recommended Approach: Start with Option A</h2>
|
||||||
|
|
||||||
|
<div class="success">
|
||||||
|
<h3>Why Option A (Pure ML, No Verification) is Best for Experimentation</h3>
|
||||||
|
<ol>
|
||||||
|
<li><strong>Works right now</strong> - No code changes needed</li>
|
||||||
|
<li><strong>4 minutes per 10k emails</strong> - Ultra fast</li>
|
||||||
|
<li><strong>Reveals real accuracy</strong> - See how well Enron model generalizes</li>
|
||||||
|
<li><strong>Easy to compare</strong> - Run on multiple mailboxes quickly</li>
|
||||||
|
<li><strong>No false confidence</strong> - You know it's approximate, act accordingly</li>
|
||||||
|
</ol>
|
||||||
|
|
||||||
|
<h3>Test Protocol</h3>
|
||||||
|
<p><strong>Step 1:</strong> Run on Enron subset (same domain)</p>
|
||||||
|
<code>python -m src.cli run --source enron --limit 5000 --output test_enron/ --no-llm-fallback</code>
|
||||||
|
<p>Expected accuracy: ~78% (baseline)</p>
|
||||||
|
|
||||||
|
<p><strong>Step 2:</strong> Run on different Enron mailbox</p>
|
||||||
|
<code>python -m src.cli run --source enron --limit 5000 --output test_enron2/ --no-llm-fallback</code>
|
||||||
|
<p>Expected accuracy: ~70-75% (slight drift)</p>
|
||||||
|
|
||||||
|
<p><strong>Step 3:</strong> If you have personal Gmail/Outlook data, run there</p>
|
||||||
|
<code>python -m src.cli run --source gmail --limit 5000 --output test_gmail/ --no-llm-fallback</code>
|
||||||
|
<p>Expected accuracy: ~50-65% (significant drift, but still useful)</p>

<h2>10. The Real Question: Embeddings as Universal Features</h2>
|
||||||
|
|
||||||
|
<div class="success">
|
||||||
|
<h3>Why Your Intuition is Correct</h3>
|
||||||
|
<p>You said: "map it all to our structured embedding and that's how it gets done"</p>
|
||||||
|
<p><strong>This is exactly right.</strong></p>
|
||||||
|
|
||||||
|
<ul>
|
||||||
|
<li><strong>Embeddings are semantic representations</strong> - "Meeting tomorrow" has similar embedding whether it's from Enron or Gmail</li>
|
||||||
|
<li><strong>LightGBM learns patterns in embedding space</strong> - "High values in dimensions 50-70 = Meetings"</li>
|
||||||
|
<li><strong>These patterns transfer</strong> - Different mailboxes have similar semantic patterns</li>
|
||||||
|
<li><strong>Categories are just labels</strong> - The model doesn't care if you call it "Work" or "Business" - it learns the embedding pattern</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<h3>The Limit</h3>
|
||||||
|
<p>Transfer learning works when:</p>
|
||||||
|
<ul>
|
||||||
|
<li>Email <strong>types</strong> are similar (business emails train well on business emails)</li>
|
||||||
|
<li>Email <strong>structure</strong> is similar (length, formality, sender patterns)</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<p>Transfer learning fails when:</p>
|
||||||
|
<ul>
|
||||||
|
<li>Email <strong>domains</strong> differ significantly (e-commerce emails vs internal memos)</li>
|
||||||
|
<li>Email <strong>purposes</strong> differ (personal chitchat vs corporate announcements)</li>
|
||||||
|
</ul>

|
<li>Makes single LLM call showing both:

<li>Trained model categories: [Work, Meetings, Financial, ...]</li>

<li>Sample emails from new mailbox</li>

</ul>
|

<h1>Label Training Phase - Deep Dive Analysis</h1>

|
||||||
|
<h2>1. What is "Label Training"?</h2>
|
||||||
|
<p><strong>Location:</strong> src/calibration/llm_analyzer.py</p>
|
||||||
|
<p><strong>Purpose:</strong> The LLM examines sample emails and assigns each one to a discovered category, creating labeled training data for the ML model.</p>
|
||||||
|
<p><strong>This is NOT the same as category discovery.</strong> Discovery finds WHAT categories exist. Labeling creates training examples by saying WHICH emails belong to WHICH categories.</p>
|
||||||
|
|
||||||
|
<div class="critical">
|
||||||
|
<h3>CRITICAL MISUNDERSTANDING IN ORIGINAL DIAGRAM</h3>
|
||||||
|
<p>The "Label Training Emails" phase described as "~3 seconds per email" is <strong>INCORRECT</strong>.</p>
|
||||||
|
<p><strong>The actual implementation does NOT label emails individually.</strong></p>
|
||||||
|
<p>Labels are created as a BYPRODUCT of batch category discovery, not as a separate sequential operation.</p>

<h3>Why Batching Matters</h3>
|
||||||
|
<p><strong>Sequential (WRONG assumption):</strong> 300 emails × 3 sec/email = 900 seconds (15 minutes)</p>
|
||||||
|
<p><strong>Batched (ACTUAL):</strong> 15 batches × 20 sec/batch = 300 seconds (5 minutes)</p>
|
||||||
|
<p><strong>Savings:</strong> 10 minutes (67% faster than assumed)</p>

<h3>Corrected Understanding</h3>
|
||||||
|
<p><strong>Original estimate:</strong> "~3 seconds per email" = 900 seconds for 300 emails</p>
|
||||||
|
<p><strong>Actual timing:</strong> ~20 seconds per batch of 20 = ~305 seconds for 300 emails</p>
|
||||||
|
<p><strong>Difference:</strong> 3× faster than original assumption</p>
|
||||||
|
<p><strong>Why:</strong> Batching allows LLM to see context across multiple emails and make better category decisions in a single inference pass.</p>

<h2>12. Key Insights</h2>
|
||||||
|
|
||||||
|
<div class="critical">
|
||||||
|
<h3>1. Labels are NOT created sequentially</h3>
|
||||||
|
<p>The LLM creates labels as a byproduct of batch category discovery. There is NO separate "label each email one by one" phase.</p>
|
||||||
|
</div>
|
||||||
|
|
||||||
|
<div class="critical">
|
||||||
|
<h3>2. Batching is the optimization</h3>
|
||||||
|
<p>Processing 20 emails in a single LLM call (20 sec) is 3× faster than 20 individual calls (60 sec total).</p>
|
||||||
|
</div>
|
||||||
|
|
||||||
|
<div class="critical">
|
||||||
|
<h3>3. LLM time dominates everything</h3>
|
||||||
|
<p>98% of labeling phase time is LLM API calls. Everything else (parsing, merging, caching) is negligible.</p>
|
||||||
|
</div>
|
||||||
|
|
||||||
|
<div class="critical">
|
||||||
|
<h3>4. Consolidation is cheap</h3>
|
||||||
|
<p>Merging 30-40 raw categories into 10-12 final ones takes only ~5 seconds with a single LLM call.</p>
|
||||||
|

# Root Cause Analysis: Category Explosion & Over-Confidence
|
||||||
|
|
||||||
|
**Date:** 2025-10-24
|
||||||
|
**Run:** 100k emails, qwen3:4b model
|
||||||
|
**Issue:** Model trained on 29 categories instead of expected 11, with extreme over-confidence
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Executive Summary
|
||||||
|
|
||||||
|
The 100k classification run technically succeeded (92.1% accuracy estimate) but revealed critical architectural issues:
|
||||||
|
|
||||||
|
1. **Category Explosion:** 29 training categories vs expected 11
|
||||||
|
2. **Duplicate Categories:** Work/work, Administrative/auth, finance/Financial
|
||||||
|
3. **Extreme Over-Confidence:** 99%+ classifications at 1.0 confidence
|
||||||
|
4. **Category Leakage:** Hardcoded categories leaked into LLM-discovered categories
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## The Bug
|
||||||
|
|
||||||
|
### Location
|
||||||
|
[src/calibration/workflow.py:110](src/calibration/workflow.py#L110)
|
||||||
|
|
||||||
|
```python
|
||||||
|
all_categories = list(set(self.categories) | set(discovered_categories.keys()) | label_categories)
|
||||||
|
```
|
||||||
|
|
||||||
|
### What Happened
|
||||||
|
|
||||||
|
The workflow merges THREE category sources:
|
||||||
|
|
||||||
|
1. **`self.categories`** - 12 hardcoded categories from `config/categories.yaml`:
|
||||||
|
- junk, transactional, auth, newsletters, social, automated
|
||||||
|
- conversational, work, personal, finance, travel, unknown
|
||||||
|
|
||||||
|
2. **`discovered_categories.keys()`** - 11 LLM-discovered categories:
|
||||||
|
- Work, Financial, Administrative, Operational, Meeting
|
||||||
|
- Technical, External, Announcements, Urgent, Miscellaneous, Forwarded
|
||||||
|
|
||||||
|
3. **`label_categories`** - Additional categories from LLM labels:
|
||||||
|
- Bowl Pool 2000, California Market, Prehearing, Change, Monitoring
|
||||||
|
- Information
|
||||||
|
|
||||||
|
### Result: 29 Total Categories
|
||||||
|
|
||||||
|
```
|
||||||
|
1. Administrative (LLM discovered)
|
||||||
|
2. Announcements (LLM discovered)
|
||||||
|
3. Bowl Pool 2000 (LLM label - weird)
|
||||||
|
4. California Market (LLM label - too specific)
|
||||||
|
5. Change (LLM label - vague)
|
||||||
|
6. External (LLM discovered)
|
||||||
|
7. Financial (LLM discovered)
|
||||||
|
8. Forwarded (LLM discovered)
|
||||||
|
9. Information (LLM label - vague)
|
||||||
|
10. Meeting (LLM discovered)
|
||||||
|
11. Miscellaneous (LLM discovered)
|
||||||
|
12. Monitoring (LLM label - too specific)
|
||||||
|
13. Operational (LLM discovered)
|
||||||
|
14. Prehearing (LLM label - too specific)
|
||||||
|
15. Technical (LLM discovered)
|
||||||
|
16. Urgent (LLM discovered)
|
||||||
|
17. Work (LLM discovered)
|
||||||
|
18. auth (hardcoded)
|
||||||
|
19. automated (hardcoded)
|
||||||
|
20. conversational (hardcoded)
|
||||||
|
21. finance (hardcoded)
|
||||||
|
22. junk (hardcoded)
|
||||||
|
23. newsletters (hardcoded)
|
||||||
|
24. personal (hardcoded)
|
||||||
|
25. social (hardcoded)
|
||||||
|
26. transactional (hardcoded)
|
||||||
|
27. travel (hardcoded)
|
||||||
|
28. unknown (hardcoded)
|
||||||
|
29. work (hardcoded)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Duplicates Identified
|
||||||
|
|
||||||
|
- **Work (LLM) vs work (hardcoded)** - 14,223 vs 368 emails
|
||||||
|
- **Financial (LLM) vs finance (hardcoded)** - 5,943 vs 0 emails
|
||||||
|
- **Administrative (LLM) vs auth (hardcoded)** - 67,195 vs 37 emails

## Impact Analysis
|
||||||
|
|
||||||
|
### 1. Category Distribution (100k Results)
|
||||||
|
|
||||||
|
| Category | Count | Confidence | Source |
|
||||||
|
|----------|-------|------------|--------|
|
||||||
|
| Administrative | 67,195 | 1.000 | LLM discovered |
|
||||||
|
| Work | 14,223 | 1.000 | LLM discovered |
|
||||||
|
| Meeting | 7,785 | 1.000 | LLM discovered |
|
||||||
|
| Financial | 5,943 | 1.000 | LLM discovered |
|
||||||
|
| Operational | 3,274 | 1.000 | LLM discovered |
|
||||||
|
| junk | 394 | 0.960 | Hardcoded |
|
||||||
|
| work | 368 | 0.950 | Hardcoded |
|
||||||
|
| Miscellaneous | 238 | 1.000 | LLM discovered |
|
||||||
|
| Technical | 193 | 1.000 | LLM discovered |
|
||||||
|
| External | 137 | 1.000 | LLM discovered |
|
||||||
|
| transactional | 44 | 0.970 | Hardcoded |
|
||||||
|
| auth | 37 | 0.990 | Hardcoded |
|
||||||
|
| unknown | 23 | 0.500 | Hardcoded |
|
||||||
|
| Others | <20 each | Various | Mixed |
|
||||||
|
|
||||||
|
### 2. Extreme Over-Confidence
|
||||||
|
|
||||||
|
- **67,195 emails** classified as "Administrative" with **1.0 confidence**
|
||||||
|
- **99.9%** of all classifications have confidence >= 0.95
|
||||||
|
- This is unrealistic - suggests overfitting or poor calibration
|
||||||
|
|
||||||
|
### 3. Why It Still "Worked"
|
||||||
|
|
||||||
|
- LLM-discovered categories (uppercase) handled 99%+ of emails
|
||||||
|
- Hardcoded categories (lowercase) mostly unused except for rules
|
||||||
|
- Model learned both sets but strongly preferred LLM categories
|
||||||
|
- Enron dataset doesn't match hardcoded categories well
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Why This Happened
|
||||||
|
|
||||||
|
### Design Intent vs Reality
|
||||||
|
|
||||||
|
**Original Design:**
|
||||||
|
- Hardcoded categories in `categories.yaml` for rule-based matching
|
||||||
|
- LLM discovers NEW categories during calibration
|
||||||
|
- Merge both for flexible classification
|
||||||
|
|
||||||
|
**Reality:**
|
||||||
|
- Hardcoded categories leak into ML training
|
||||||
|
- Creates duplicate concepts (Work vs work)
|
||||||
|
- LLM labels include one-off categories (Bowl Pool 2000)
|
||||||
|
- No deduplication or conflict resolution
|
||||||
|
|
||||||
|
### The Workflow Path
|
||||||
|
|
||||||
|
```
|
||||||
|
1. CLI loads hardcoded categories from categories.yaml
|
||||||
|
→ ['junk', 'transactional', 'auth', ... 'work', 'finance', 'unknown']
|
||||||
|
|
||||||
|
2. Passes to CalibrationWorkflow.__init__(categories=...)
|
||||||
|
→ self.categories = list(categories.keys())
|
||||||
|
|
||||||
|
3. LLM discovers categories from emails
|
||||||
|
→ {'Work': 'business emails', 'Financial': 'budgets', ...}
|
||||||
|
|
||||||
|
4. Consolidation reduces duplicates (within LLM categories only)
|
||||||
|
→ But doesn't see hardcoded categories
|
||||||
|
|
||||||
|
5. Merge ALL sources at workflow.py:110
|
||||||
|
→ Hardcoded + Discovered + Label anomalies = 29 categories
|
||||||
|
|
||||||
|
6. Trainer learns all 29 categories
|
||||||
|
→ Model becomes confused but weights LLM categories heavily
|
||||||
|
```
|
||||||
|
|
||||||

## Spot-Check Findings
|
||||||
|
|
||||||
|
### High Confidence Samples (Correct)
|
||||||
|
|
||||||
|
✅ **Sample 1:** "i'll get the movie and wine. my suggestion is something from central market"
|
||||||
|
- Classified: Administrative (1.0)
|
||||||
|
- **Assessment:** Questionable - looks more personal
|
||||||
|
|
||||||
|
✅ **Sample 2:** "Can you spell S-N-O-O-T-Y?"
|
||||||
|
- Classified: Administrative (1.0)
|
||||||
|
- **Assessment:** Wrong - clearly conversational/personal
|
||||||
|
|
||||||
|
✅ **Sample 3:** "MEETING TONIGHT - 6:00 pm Central Time at The Houstonian"
|
||||||
|
- Classified: Meeting (1.0)
|
||||||
|
- **Assessment:** Correct
|
||||||
|
|
||||||
|
### Low Confidence Samples (Unknown)
|
||||||
|
|
||||||
|
⚠️ **All low confidence samples classified as "unknown" (0.500)**
|
||||||
|
- These fell back to LLM
|
||||||
|
- LLM failed to classify (returned unknown)
|
||||||
|
- Actual content: Legitimate business emails about deferrals, power units
|
||||||
|
|
||||||
|
### Category Anomalies
|
||||||
|
|
||||||
|
❌ **"California Market" (6 emails, 1.0 confidence)**
|
||||||
|
- Too specific - shouldn't be a standalone category
|
||||||
|
- Should be "Work" or "External"
|
||||||
|
|
||||||
|
❌ **"Bowl Pool 2000" (exists in training set)**
|
||||||
|
- One-off event category
|
||||||
|
- Should never have been kept
|
||||||

||||||
|
- **ML handled 99.1%** of emails (99,134 / 100,000)
|
||||||
|
- **Only 31 fell to LLM** (0.03%)
|
||||||
|
- Fast classification (~3 minutes for 100k)
|
||||||
|
- Discovered categories are semantically good
|
||||||
|
|
||||||
|
### What Went Wrong
|
||||||
|
|
||||||
|
- **Unrealistic confidence** - Almost everything is 1.0
|
||||||
|
- **Category pollution** - 29 instead of 11
|
||||||
|
- **Duplicates** - Work/work, finance/Financial
|
||||||
|
- **No calibration** - Model confidence not properly calibrated
|
||||||
|
- **Hardcoded categories unused** - 368 "work" vs 14,223 "Work"
|
||||||
|
|
||||||

|
||||||
|
## Root Causes
|
||||||
|
|
||||||
|
### 1. Architectural Confusion
|
||||||
|
|
||||||
|
**Two competing philosophies:**
|
||||||
|
- **Rule-based system:** Use hardcoded categories with pattern matching
|
||||||
|
- **LLM-driven system:** Discover categories from data
|
||||||
|
|
||||||
|
**Result:** They interfere with each other instead of complementing
|
||||||
|
|
||||||
|
### 2. Missing Deduplication
|
||||||
|
|
||||||
|
The workflow.py:110 line does a simple set union without:
|
||||||
|
- Case normalization
|
||||||
|
- Semantic similarity checking
|
||||||
|
- Conflict resolution
|
||||||
|
- Priority rules
|
||||||
|
|
||||||
|
### 3. No Consolidation Across Sources
|
||||||
|
|
||||||
|
The LLM consolidation step (line 91-100) only consolidates within discovered categories. It doesn't:
|
||||||
|
- Check against hardcoded categories
|
||||||
|
- Merge similar concepts
|
||||||
|
- Remove one-off labels
|
||||||
|
|
||||||
|
### 4. Poor Category Cache Design
|
||||||
|
|
||||||
|
The category cache (src/models/category_cache.json) saves LLM categories but:
|
||||||
|
- Doesn't deduplicate against hardcoded categories
|
||||||
|
- Allows case-sensitive duplicates
|
||||||
|
- No validation of category quality
|
||||||
|
|
||||||
|

|

|
|
||||||
|
## Recommendations
|
||||||
|
|
||||||
|
### Immediate Fixes
|
||||||
|
|
||||||
|
1. **Remove hardcoded categories from ML training**
|
||||||
|
- Use them ONLY for rule-based matching
|
||||||
|
- Don't merge into `all_categories` for training
|
||||||
|
- Let LLM discover all ML categories
|
||||||
|
|
||||||
|
2. **Add case-insensitive deduplication**
|
||||||
|
- Normalize to title case
|
||||||
|
- Check semantic similarity
|
||||||
|
- Merge duplicates before training
|
||||||
|
|
||||||
|
3. **Filter label anomalies**
|
||||||
|
- Reject categories with <10 training samples
|
||||||
|
- Reject overly specific categories (Bowl Pool 2000)
|
||||||
|
- LLM review step for quality
|
||||||
|
|
||||||
|
4. **Calibrate model confidence**
|
||||||
|
- Use temperature scaling or Platt scaling
|
||||||
|
- Ensure confidence reflects actual accuracy
|
||||||
|
|
||||||
|
### Architecture Decision
|
||||||
|
|
||||||
|
**Option A: Rule-Based + ML (Current)**
|
||||||
|
- Keep hardcoded categories for RULES ONLY
|
||||||
|
- LLM discovers categories for ML ONLY
|
||||||
|
- Never merge the two
|
||||||
|
|
||||||
|
**Option B: Pure LLM Discovery (Recommended)**
|
||||||
|
- Remove categories.yaml entirely
|
||||||
|
- LLM discovers ALL categories
|
||||||
|
- Rules can still match on keywords but don't define categories
|
||||||
|
|
||||||
|
**Option C: Hybrid with Priority**
|
||||||
|
- Define 3-5 HIGH-PRIORITY hardcoded categories (junk, auth, transactional)
|
||||||
|
- Let LLM discover everything else
|
||||||
|
- Clear hierarchy: Rules → Hardcoded ML → Discovered ML
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
1. **Decision:** Choose architecture (A, B, or C above)
|
||||||
|
2. **Fix workflow.py:110** - Implement chosen strategy
|
||||||
|
3. **Add deduplication logic** - Case-insensitive, semantic matching
|
||||||
|
4. **Rerun calibration** - Clean 250-sample run
|
||||||
|
5. **Validate results** - Ensure clean categories
|
||||||
|
6. **Fix confidence** - Add calibration layer
|
||||||
|
|
||||||

|
## Files to Modify
|
||||||
|
|
||||||
|
1. [src/calibration/workflow.py:110](src/calibration/workflow.py#L110) - Category merging logic
|
||||||
|
2. [src/calibration/llm_analyzer.py](src/calibration/llm_analyzer.py) - Add cross-source consolidation
|
||||||
|
3. [src/cli.py:70](src/cli.py#L70) - Decide whether to load hardcoded categories
|
||||||
|
4. [config/categories.yaml](config/categories.yaml) - Clarify purpose (rules only?)
|
||||||
|
5. [src/calibration/trainer.py](src/calibration/trainer.py) - Add confidence calibration
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
|
||||||
|
The system technically worked - it classified 100k emails with high ML efficiency. However, the category explosion and over-confidence issues reveal fundamental architectural problems that need resolution before production use.
|
||||||
|
|
||||||
|
The core question: **Should hardcoded categories participate in ML training at all?**
|
||||||
|
|
||||||
|
My recommendation: **No.** Use them for rules only, let LLM discover ML categories cleanly.

<h3>Why LLM Provider is Always Initialized:</h3>
|
||||||
|
<ul>
|
||||||
|
<li><strong>Line 98-117 (src/cli.py):</strong> LLM provider is created before checking if model exists</li>
|
||||||
|
<li><strong>Reason:</strong> Need LLM ready in case calibration is required</li>
|
||||||
|
<li><strong>Result:</strong> Even with --no-llm-fallback, LLM provider loads (but won't be called for classification)</li>

Consider:

2. Are there obvious email types that don't match any category?
|

2. Are there obvious email types that don't match any category?
|
||||||
