监督机器学习 (ML) 算法准确地分类斑马鱼的行为,在一致性方面超过人类注释者. 然而,时间聚合方法可以掩盖对详细表型化至关重要的关键短暂行为.

科学领域:

  • 行为神经科学 行为神经科学
  • 机器学习应用程序 机器学习应用程序
  • 动物行为分析 动物行为分析

背景情况:

  • 准确的行为注释在神经科学中至关重要但具有挑战性.
  • 手动评分是耗时的,可变的,容易错过短暂的行为.
  • 监督机器学习 (ML) 提供自动化,一致和更少偏见的行为分类.

研究的目的:

  • 为了将多个监督的ML算法与专家人类注释对象进行基准测试,以确定斑马鱼类似发作的行为.
  • 评估框架级分析,后处理过器和块级时间聚合对行为分类准确性的影响.
  • 将基于ML的行为表型的可复制性和可扩展性与传统的手动评分进行比较.

主要方法:

  • 基准测试了五种ML算法:随机森林,XGBoost,支持矢量机,k-最近邻居和多层感知器 (MLP).
  • 利用了12名专家评分员对12个成年斑马鱼的43000多个手动注释的视频.
  • 应用框架级分析,行为信息过器和块级时间聚合以进行评估.

主要成果:

  • 机器学习算法,特别是随机森林,XGBoost和MLP,在分类斑马鱼行为方面取得了很高的准确性.
  • 对于模两可的行为,注释变化率最高,突出了人类注释者面临的挑战.
