## Model Description

- **Finetuned from model klue/bert :** (https://huggingface.co/klue/bert-base)
- i got **test_accuracy: 0.9041**

## Uses

- use to sentimental analysis task

## How to Get Started with the Model

```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("seongyeon1/klue-base-finetuned-nsmc")
model = AutoModelForSequenceClassification.from_pretrained("seongyeon1/klue-base-finetuned-nsmc")
```

```python
from transformers import pipeline

pipe = pipeline("text-classification", model="seongyeon1/klue-base-finetuned-nsmc")
pipe("진짜 별로더라") # [{'label': 'LABEL_0', 'score': 0.999700665473938}]
pipe("굿굿")        # [{'label': 'LABEL_1', 'score': 0.9875587224960327}]

```

## Training Details

### Training Data

- nsmc datasets (https://huggingface.co/datasets/e9t/nsmc)
```python
from datasets import load_dataset

dataset = load_dataset('nsmc')
```

#### Preprocessing

- bert's default is 512, but it costs a lot of time.
  - maxlen = 55

```python
def tokenize_function_with_max(examples, maxlen=maxlen):
    encodings = tokenizer(examples['document'],max_length=maxlen, truncation=True, padding='max_length')
    return encodings
```

#### Training Hyperparameters

- learning rate=2e-5, weight decay=0.01, batch size=32, epochs=2

#### Metrics

- **accuracy**
- label ratio is about almost balanced
