## 简介 Brief Introduction |
|
|
|
在Randeng-T5-784M的基础上，收集了100个左右的中文数据集，进行Text2Text统一范式的有监督任务预训练。 |
|
|
|
On the basis of Randeng-T5-784M, about 100 Chinese datasets were collected and pre-trained for the supervised task of Text2Text unified paradigm. |
|
|
|
本模型在中文zero-shot榜单ZeroClue上取得了第三名（不包括人类）的成绩，在所有基于T5（encoder-decoder架构）的模型中排名第一。 |
|
|
|
This model achieved the 3rd place (excluding humans) on the Chinese zero-shot benchmark ZeroClue, ranking first among all models based on T5 (encoder-decoder architecture). |

基于[Randeng-T5-784M](https://huggingface.co/IDEA-CCNL/Randeng-T5-784M)，我们在收集的100+个中文领域的多任务数据集（从中采样了30w+个样本）上微调了它，得到了此多任务版本。这些多任务包括：情感分析，新闻分类，文本分类，意图识别，自然语言推理，多项选择，指代消解，抽取式阅读理解，实体识别，关键词抽取，生成式摘要。 |
|
|
|
Based on [Randeng-T5-784M](https://huggingface.co/IDEA-CCNL/Randeng-T5-784M), we fine-tuned it on a collection of 100+ multitasking datasets in Chinese domains (from which 30w+ samples were sampled) to obtain this multitasking version. These multitasks include: sentiment analysis, news classification, text classification, intention recognition, natural language inference, multiple choice, denotational disambiguation, extractive reading comprehension, entity recognition, keyword extraction, and generative summarization. |

|
## 使用 Usage |
|
|
|
```python |
|
import torch |
|
from transformers import T5Tokenizer, T5Config, T5ForConditionalGeneration |
|
|
|
# load tokenizer and model |
|
pretrained_model = "IDEA-CCNL/Randeng-T5-784M-MultiTask-Chinese" |
|
|
|
special_tokens = ["<extra_id_{}>".format(i) for i in range(100)] |
|
tokenizer = T5Tokenizer.from_pretrained( |
|
pretrained_model, |
|
do_lower_case=True, |
|
max_length=512, |
|
truncation=True, |
|
additional_special_tokens=special_tokens, |
|
) |
|
config = T5Config.from_pretrained(pretrained_model) |
|
model = T5ForConditionalGeneration.from_pretrained(pretrained_model, config=config) |
|
model.resize_token_embeddings(len(tokenizer)) |
|
model.eval() |
|
|
|
# tokenize |
|
text = "新闻分类任务：【微软披露拓扑量子计算机计划！】这篇文章的类别是什么？故事/文化/娱乐/体育/财经/房产/汽车/教育/科技" |
|
encode_dict = tokenizer(text, max_length=512, padding='max_length',truncation=True) |
|
|
|
inputs = { |
|
"input_ids": torch.tensor([encode_dict['input_ids']]).long(), |
|
"attention_mask": torch.tensor([encode_dict['attention_mask']]).long(), |
|
} |
|
|
|
# generate answer |
|
logits = model.generate( |
|
input_ids = inputs['input_ids'], |
|
max_length=100, |
|
do_sample= True |
|
# early_stopping=True, |
|
) |
|
|
|
logits=logits[:,1:] |
|
predict_label = [tokenizer.decode(i,skip_special_tokens=True) for i in logits] |
|
print(predict_label) |
|
|
|
# model output: 科技 |
|
``` |
|
|
|
除了分类任务，其他任务的数据构造例子如下： |
|
|
|
In addition to classification tasks, data construction examples of other tasks are as follows: |
