# Deita-Quality-Scorer

Deita-Quality-Scorer is a tool for automatically annotating the Instruction Complexity of SFT data.

## Uses

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import numpy as np
from scipy.special import softmax
model_name = "hkust-nlp/Deita-Complexity-Scorer"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)


def infer_complexity(model, tokenizer, input_text):
	complexity_template = ("You are a helpful assistant. Please identify the complexity score of the following user query. \n##Query: {instruction}  \n##Complexity: ")
	user_input = complexity_template.format(instruction=input_text)
	input_ids = tokenizer.encode(user_input, return_tensors="pt")
	max_length = 512
	outputs = model.generate(input_ids, max_length=512, num_return_sequences=1, return_dict_in_generate=True, output_scores=True)
	logprobs_list = outputs.scores[0][0]
	score_logits = []
	id2score = {
        29896: "1",
        29906: "2",
        29941: "3",
        29946: "4",
        29945: "5",
        29953: "6"
    }
	score_template = np.array([1,2,3,4,5,6])
	for k in id2score:
	    score_logits.append(logprobs_list[k])
	score_logits = np.array(score_logits)
	score_npy = softmax(score_logits, axis=0)
	score_npy = score_npy * score_template

	score_npy = np.sum(score_npy, axis=0)
	return score_npy

input_text = "write a performance review for a junior data scientist"
complexity_score = infer_complexity(model, tokenizer, input_text)

print(complexity_score)
