# distillbert_conv_quality_score |
|
|
|
This model is a fine-tuned version of [distilbert-base-uncased](https://huggingface.co/distilbert-base-uncased) on the conv_ai_2 dataset. |
|
It was trained to Generate a score from a conversation. The score is a float between 0 and 1. |
|
|
|
|
|
It achieves the following results on the evaluation set: |
|
- training/loss: 0.0165 |
|
- validation/loss: 0.0149 |
|

|
## Usage |
|
|
|
```python |
|
from transformers import AutoTokenizer, AutoModelForSequenceClassification |
|
|
|
model_name = "alespalla/distillbert_conv_quality_score" |
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
model = AutoModelForSequenceClassification.from_pretrained(model_name) |
|
|
|
conversation = ''' |
|
Q: Begin |
|
A: lol ! do you think it is strange to feel like you have been through life before ? |
|
Q: Hellow |
|
A: I don't understand you 🙈. Also, try to guess: i like to ... |
|
Q: How are you? |
|
A: make time stop, funny you :) |
|
Q: What is your name? |
|
A: jessie. hows your day going ? 😃 |
|
''' |
|
|
|
score = model(**tokenizer(conversation, return_tensors='pt')).logits.item() |
|
print(f"Score: {score}") |
|
``` |
|
|
|
## Training and evaluation data |
|
|
|
The training data was generated from `conv_ai_2` using the following function |
|
|
|
```python |
|
|
|
from datasets import load_dataset |
|
|
|
def get_dataset(regression=False): |
|
|
|
db = load_dataset("conv_ai_2") |
|
|
|
def generate_converation(elem): |
|
text = "" |
|
for idx, txt in enumerate(elem["dialog"]): |
|
if idx % 2: |
|
text += f"A: {txt['text']}\n" |
|
else: |
|
text += f"Q: {txt['text']}\n" |
|
if regression: |
|
return {'text': text, "labels": (elem['eval_score'] - 1)/4} |
|
return {'text': text, "labels": elem['eval_score'] - 1} |
|
|
|
db = db.filter(lambda example: example["eval_score"] > 0) |
|
db = db.map(generate_converation, remove_columns=db['train'].column_names) |
|
db = db['train'].train_test_split(test_size=0.2).shuffle(42) |
|
|
|
return db |
|
|
|
``` |
|
