## Evaluation

Code : 
```
import torch
import numpy as np
from sklearn.metrics import pairwise_distances
from tqdm import tqdm
import datasets
def get_embedding(text, model):
    with torch.no_grad():
        embedding = model.encode(text)['dense_vecs']
    return embedding


dataset = datasets.load_dataset("jaeyong2/Ko-emb-PreView")
validation_dataset = dataset["test"].select(range((1000)))


def evaluate(validation_dataset):
    correct_count = 0

    for item in tqdm(validation_dataset):
        query_embedding = get_embedding(item["context"], fine_tuned_model)
        document_embedding = get_embedding(item["Title"], fine_tuned_model)
        negative_embedding = get_embedding(item["Fake Title"], fine_tuned_model)
      

        # 쿼리와 모든 문서 간의 유사도 계산 (코사인 거리 사용)
        positive_distances = pairwise_distances(query_embedding.reshape(1, -1), document_embedding.reshape(1, -1), metric="cosine")
        negative_distances = pairwise_distances(query_embedding.reshape(1, -1), negative_embedding.reshape(1, -1), metric="cosine")

        if positive_distances < negative_distances:
            correct_count += 1

    accuracy = correct_count / len(validation_dataset)
    return accuracy

results = evaluate(validation_dataset)
print(f"Validation Results: {results}")
```

Accuracy
- BAAI/bge-m3: 0.971
- jaeyong2/gte-multilingual-base-Ko-embedding : 0.992
