Abstract

This application discloses a question and answer reading comprehension model acquisition method, device, electronic equipment, and storage medium, involving the field of deep learning, wherein the method may include: for N models with different structures, N is a positive integer greater than one, respectively using unsupervised training The data is pre-trained to obtain N pre-training models, and different models correspond to different pre-training tasks; the main task is the question-and-answer reading comprehension task, and other predetermined natural language processing tasks are used as auxiliary tasks, using supervised training data Fine-tune each pre-trained model to obtain N fine-tuned models; determine the final required Q&A reading comprehension model based on the N fine-tuned models. Applying the solution described in this application can improve the generalization ability of the model, etc.

Description

technical field [0001] This application relates to computer application technology, in particular to a method, device, electronic device and storage medium for acquiring a question-and-answer reading comprehension model in the field of deep learning. Background technique [0002] Question and answer reading comprehension technology refers to given one or more paragraphs (P) and a question (Q), using machine learning methods to let the model predict the answer (A). [0003] The current question-and-answer reading comprehension models are mostly obtained based on pre-training-fine-tuning methods, that is, first select a model structure, then pre-train on a large number of unsupervised training data from a single source, and then use supervised training data, in a single The Q&A reading comprehension task is fine-tuned to obtain the final required Q&A reading comprehension model. [0004] However, the model structure and training tasks of the above method are single, which mak...
