🔧 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}")
