HeackMT5-ZhSum100k: A Summarization Model for Chinese Texts

This model, heack/HeackMT5-ZhSum100k, is a fine-tuned mT5 model for Chinese text summarization tasks. It was trained on a diverse set of Chinese datasets and is able to generate coherent and concise summaries for a wide range of texts.

Model Details

Model: mT5
Language: Chinese
Training data: Mainly Chinese Financial News Sources, NO BBC or CNN source. Training data contains 1M lines.
Finetuning epochs: 10

Evaluation Results

The model achieved the following results:

ROUGE-1: 56.46
ROUGE-2: 45.81
ROUGE-L: 52.98
ROUGE-Lsum: 20.22

Usage

Here is how you can use this model for text summarization:

from transformers import MT5ForConditionalGeneration, T5Tokenizer

model = MT5ForConditionalGeneration.from_pretrained("heack/HeackMT5-ZhSum100k")
tokenizer = T5Tokenizer.from_pretrained("heack/HeackMT5-ZhSum100k")

财联社5月22日讯，据平安包头微信公众号消息，近日，包头警方发布一起利用人工智能（AI）实施电信诈骗的典型案例，福州市某科技公司法人代表郭先生10分钟内被骗430万元。
4月20日中午，郭先生的好友突然通过微信视频联系他，自己的朋友在外地竞标，需要430万保证金，且需要公对公账户过账，想要借郭先生公司的账户走账。
基于对好友的信任，加上已经视频聊天核实了身份，郭先生没有核实钱款是否到账，就分两笔把430万转到了好友朋友的银行卡上。郭先生拨打好友电话，才知道被骗。骗子通过智能AI换脸和拟声技术，佯装好友对他实施了诈骗。
值得注意的是，骗子并没有使用一个仿真的好友微信添加郭先生为好友，而是直接用好友微信发起视频聊天，这也是郭先生被骗的原因之一。骗子极有可能通过技术手段盗用了郭先生好友的微信。幸运的是，接到报警后，福州、包头两地警银迅速启动止付机制，成功止付拦截336.84万元，但仍有93.16万元被转移，目前正在全力追缴中。
