lmqg/t5-base-squad-qag 模型卡片

该模型是针对问答对生成任务在 lmqg/qag_squad 数据集（dataset_name: default）上通过 lmqg 进行微调的 t5-base 的版本。

概述

• 语言模型： t5-base
• 语言：en
• 训练数据： lmqg/qag_squad （默认）
• 在线演示： https://autoqg.net/
• 代码库： https://github.com/asahi417/lm-question-generation
• 论文： https://arxiv.org/abs/2210.03992

用法

• 使用 lmqg

from lmqg import TransformersQG

# initialize model
model = TransformersQG(language="en", model="lmqg/t5-base-squad-qag")

# model prediction
question_answer_pairs = model.generate_qa("William Turner was an English painter who specialised in watercolour landscapes")

• 使用 transformers

from transformers import pipeline

pipe = pipeline("text2text-generation", "lmqg/t5-base-squad-qag")
output = pipe("generate question and answer: Beyonce further expanded her acting career, starring as blues singer Etta James in the 2008 musical biopic, Cadillac Records.")

评估

• 度量指标（问题和答案生成）： raw metric file

训练超参数

在微调过程中使用了以下超参数：

• dataset_path: lmqg/qag_squad
• dataset_name: default
• input_types: ['paragraph']
• output_types: ['questions_answers']
• prefix_types: ['qag']
• model: t5-base
• max_length: 512
• max_length_output: 256
• epoch: 17
• batch: 8
• lr: 0.0001
• fp16: False
• random_seed: 1
• gradient_accumulation_steps: 8
• label_smoothing: 0.15

完整的配置可以在 fine-tuning config file 找到。
