摘要:

睡眠障碍严重影响人类健康和生活,将睡眠阶段准确分类是检测和治疗睡眠障碍的关键。近年来,基于深度学习的方法超越了传统机器学习方法及人类专家。然而,深度学习的内部结构复杂,需要对计算机及医学领域熟悉的专家进行设计。旨在分析现有基于深度学习的睡眠分期模型中的关系归纳偏置,探索睡眠分期模型设计基本原则。对平移不变性、时间不变性和分层处理等关系归纳偏置进行分析。首先按照模型中是否包含具有平移不变性的卷积层和具有时间不变性的循环层将其分为三类:卷积神经网络框架、循环神经网络框架和混合神经网络框架。然后按照模型中对帧、片段和序列的分层处理方式进行了更加细致的分类。接着分析模型中包含不同关系归纳偏置对睡眠分期的性能影响,提出了设计睡眠分期模型需要引入与任务相匹配的关系归纳偏置。最后讨论了基于深度学习睡眠分期方法的优越性与局限性,以及未来可能需要使用更加高级的关系归纳偏置对知识进行更加抽象的表达并与其他人工智能技术相结合。

Abstract:

Sleep disorders seriously affect human health and life. Accurate classification of sleep stages is the key to detecting and treating sleep disorders. In recent years, methods based on deep learning have surpassed traditional machine learning methods and human experts. However, the internal structure of deep learning is complex and requires to be designed by expert who is familiar with the computer and medical fields. This paper aims to analyze the relational induction biases in the existing sleep staging model based on deep learning, and explores the basic principles of sleep staging model design. This paper analyzes relational induction biases such as translation invariance, time invariance and hierarchical processing. Firstly, the model is divided into three categories according to whether it contains convolution layer with translation invariance and recurrent layer with time invariance: convolutional neural network framework, recurrent neural network framework and hybrid neural network framework. Secondly, according to the hierarchical processing method of the frame, segment and sequence in the model, a more detailed classification is carried out. Thirdly, it analyzes the impact of different relational induction biases in the model on the performance of sleep staging. It is proposed that a relational inductive bias matched the task should be introduced when the automatic sleep staging model is designed. Finally, the advantages and limitations of sleep staging based on deep learning are discussed, and it may be necessary to use more advanced relationship induction bias to express knowledge more abstractly and combine it with other artificial intelligence technologies in the future.
