+
## π Quick Start
|
| 49 |
+
|
| 50 |
+
### Installation
|
| 51 |
+
```bash
|
| 52 |
+
pip install -r api/requirements.txt
|
| 53 |
+
```
|
| 54 |
+
|
| 55 |
+
### Basic Usage
|
| 56 |
+
```python
|
| 57 |
+
from api.inference_api import SentenceEmbeddingInference
|
| 58 |
+
|
| 59 |
+
# Initialize model
|
| 60 |
+
model = SentenceEmbeddingInference("./")
|
| 61 |
+
|
| 62 |
+
# Generate embeddings
|
| 63 |
+
texts = ["Your text here", "Another text"]
|
| 64 |
+
embeddings = model.get_embeddings(texts)
|
| 65 |
+
|
| 66 |
+
# Compute similarity
|
| 67 |
+
similarity = model.compute_similarity("Text 1", "Text 2")
|
| 68 |
+
|
| 69 |
+
# Find similar texts
|
| 70 |
+
query = "Search query"
|
| 71 |
+
candidates = ["Text A", "Text B", "Text C"]
|
| 72 |
+
results = model.find_similar_texts(query, candidates, top_k=3)
|
| 73 |
+
```
|
| 74 |
+
|
| 75 |
+
### Alternative Usage with Sentence Transformers
|
| 76 |
+
```python
|
| 77 |
+
from sentence_transformers import SentenceTransformer
|
| 78 |
+
|
| 79 |
+
# Load the model
|
| 80 |
+
model = SentenceTransformer('LNTTushar/sentence-embedding-model-production-release')
|
| 81 |
+
|
| 82 |
+
# Generate embeddings
|
| 83 |
+
sentences = ["Machine learning is transforming AI", "AI includes machine learning"]
|
| 84 |
+
embeddings = model.encode(sentences)
|
| 85 |
+
|
| 86 |
+
# Compute similarity
|
| 87 |
+
similarity = model.similarity(sentences[0], sentences[1])
|
| 88 |
+
print(f"Similarity: {similarity:.4f}")
|
| 89 |
+
```
|
| 90 |
