## 🔧 Quick Start |
|
|
|
|
|
### PyTorch Usage |
|
|
|
|
|
```python |
|
|
from sentence_transformers import SentenceTransformer |
|
|
|
|
|
# Load the model from Hugging Face Hub |
|
|
model = SentenceTransformer('your-username/indonesian-embedding-small') |
|
|
|
|
|
# Or load locally if downloaded |
|
|
# model = SentenceTransformer('indonesian-embedding-small/pytorch') |
|
|
|
|
|
# Encode sentences |
|
|
sentences = [ |
|
|
"AI akan mengubah dunia teknologi", |
|
|
"Kecerdasan buatan akan mengubah dunia", |
|
|
"Jakarta adalah ibu kota Indonesia" |
|
|
] |
|
|
|
|
|
embeddings = model.encode(sentences) |
|
|
print(f"Embeddings shape: {embeddings.shape}") |
|
|
|
|
|
# Calculate similarity |
|
|
from sklearn.metrics.pairwise import cosine_similarity |
|
|
similarity = cosine_similarity([embeddings[0]], [embeddings[1]])[0][0] |
|
|
print(f"Similarity: {similarity:.4f}") |
|
|
``` |
|
|
|
|
|
### ONNX Runtime Usage (Recommended for Production) |
|
|
|
|
|
```python |
|
|
import onnxruntime as ort |
|
|
import numpy as np |
|
|
from transformers import AutoTokenizer |
|
|
|
|
|
# Load quantized ONNX model (7.8x faster) |
|
|
session = ort.InferenceSession( |
|
|
'indonesian-embedding-small/onnx/indonesian_embedding_q8.onnx', |
|
|
providers=['CPUExecutionProvider'] |
|
|
) |
|
|
|
|
|
# Load tokenizer |
|
|
tokenizer = AutoTokenizer.from_pretrained('indonesian-embedding-small/onnx') |
|
|
|
|
|
# Encode text |
|
|
text = "Teknologi AI sangat canggih" |
|
|
inputs = tokenizer(text, padding=True, truncation=True, |
|
|
max_length=384, return_tensors="np") |
|
|
|
|
|
# Run inference |
|
|
outputs = session.run(None, { |
|
|
'input_ids': inputs['input_ids'], |
|
|
'attention_mask': inputs['attention_mask'] |
|
|
}) |
|
|
|
|
|
# Get embeddings (mean pooling) |
|
|
embeddings = outputs[0] |
|
|
attention_mask = inputs['attention_mask'] |
|
|
masked_embeddings = embeddings * np.expand_dims(attention_mask, -1) |
|
|
sentence_embedding = np.mean(masked_embeddings, axis=1) |
|
|
|
|
|
print(f"Embedding shape: {sentence_embedding.shape}") |
|
|
``` |
