+# Korean-Sentence-Embedding
+🍭 Korean sentence embedding repository. You can download the pre-trained models and inference right away, also it provides environments where individuals can train models.

+## Quick tour
+```python
+import torch
+from transformers import AutoModel, AutoTokenizer
+
+def cal_score(a, b):
+    if len(a.shape) == 1: a = a.unsqueeze(0)
+    if len(b.shape) == 1: b = b.unsqueeze(0)
+
+    a_norm = a / a.norm(dim=1)[:, None]
+    b_norm = b / b.norm(dim=1)[:, None]
+    return torch.mm(a_norm, b_norm.transpose(0, 1)) * 100
