| ```python |
| from transformers import AutoTokenizer, AutoModelForSequenceClassification |
| import torch, torch.nn.functional as F |
| |
| REPO = "kbsooo/mjuclaw-intent-classifier" |
| tok = AutoTokenizer.from_pretrained(REPO) |
| model = AutoModelForSequenceClassification.from_pretrained(REPO).eval() |
| |
| def classify(text: str, abuse_threshold: float = 0.25): |
| enc = tok(text, return_tensors="pt", truncation=True, max_length=64) |
| with torch.inference_mode(): |
| probs = F.softmax(model(**enc).logits[0], dim=-1) |
| top_id = int(probs.argmax()) |
| top_label = model.config.id2label[top_id] |
| abuse_id = model.config.label2id["abuse"] |
| p_abuse = float(probs[abuse_id]) |
| # recall ๋ณด์ : p(abuse)๊ฐ ์๊ณ ์ด์์ด๋ฉด abuse๋ก ๋ฎ์ด์ |
| if top_label != "abuse" and p_abuse >= abuse_threshold: |
| top_label = "abuse" |
| return top_label, float(probs[top_id]), p_abuse |
| |
| print(classify("๊ณผ์ ๋ญ๋จ์์ด")) # โ ('service.lms.digest', 0.708, ...) |

|
| ## Training |
|
|
| - **Dataset:** [`kbsooo/mjuclaw-intent-dataset`](https://huggingface.co/datasets/kbsooo/mjuclaw-intent-dataset) (4,474 synthetic Korean queries, stratified 85/15 split) |
| - **Hardware:** Kaggle T4 GPU |
| - **Wall time:** ~4 min |
| - **Optimizer:** AdamW, LR 3e-5, warmup 10%, weight decay 0.01 |
| - **Batch:** 32 |
| - **Max seq length:** 64 |
| - **Epochs:** 13 (early stopped from 15, patience=2 on macro F1) |
| - **Loss:** Weighted CrossEntropy with `sklearn.utils.class_weight("balanced")` |
| - **Precision:** fp16 |
|
|
