| # ⚠️ Deprecated — Ticket Classifier (v1) |
|
|
| **This model is deprecated.** It was trained on a synthetic dataset with a known labeling |
| issue in the `general` category (see details below), which significantly understated its |
| usable accuracy. It is kept here only for reproducibility and as a before/after reference. |
|
|
| **Use [`sheethal00/ticket-classifier-lora`](https://huggingface.co/sheethal00/ticket-classifier-lora) instead.** |
|
|
| ## Why this version was deprecated |
|
|
| The data generation prompt for the `general` category had no positive definition |
| ("everything else"), causing generated tickets to overlap heavily with the other four |
| categories. This model's real classification ability was masked by noisy validation |
| labels — measured accuracy was 71.7% / F1 (macro) 0.704, compared to 95.1% / 0.953 |
| after the labeling issue was fixed and the model retrained. See the main repo's model |
| card for the full before/after comparison. |
|
|
| ## Training details |
|
|
| Same architecture and hyperparameters as v2 (LoRA rank 16, alpha 32, target modules |
| q_proj/v_proj, base model meta-llama/Llama-3.2-1B) — the only difference is the |
| training data quality. |
