摘要:

尽管机器学习工具发展迅速,但大多数神经解码方法仍然使用传统方法。现代机器学习工具功能多样且易于使用,有可能显著提高解码性能。本教程介绍了如何有效地应用这些算法的典型解码问题。我们提供了应用常见机器学习方法的描述、最佳实践和代码,包括神经网络和梯度提升。我们还提供了详细的比较各种方法的性能在运动皮层,体感皮层和海马体的解码尖峰活动的任务。现代方法,特别是神经网络和集成,显着优于传统的方法,如维纳和卡尔曼滤波器。提高神经解码算法的性能可以让神经科学家更好地理解神经元群体中包含的信息,并有助于推进脑机接口等工程应用。

英文摘要:

Despite rapid advances in machine learning tools, the majority of neural decoding approaches still use traditional methods. Modern machine learning tools, which are versatile and easy to use, have the potential to significantly improve decoding performance. This tutorial describes how to effectively apply these algorithms for typical decoding problems. We provide descriptions, best practices, and code for applying common machine learning methods, including neural networks and gradient boosting. We also provide detailed comparisons of the performance of various methods at the task of decoding spiking activity in motor cortex, somatosensory cortex, and hippocampus. Modern methods, particularly neural networks and ensembles, significantly outperform traditional approaches, such as Wiener and Kalman filters. Improving the performance of neural decoding algorithms allows neuroscientists to better understand the information contained in a neural population and can help advance engineering applications such as brain machine interfaces.
