How can a machine learn from experience? Probabilistic modelling provides a framework for understanding what learning is, and has therefore emerged as one of the principal theoretical and practical approaches for designing machines that learn from data acquired through experience. The probabilistic framework, which describes how to represent and manipulate uncertainty about models and predictions, has a central role in scientific data analysis, machine learning, robotics, cognitive science and artificial intelligence. This Review provides an introduction to this framework, and discusses some of the state-of-the-art advances in the field, namely, probabilistic programming, Bayesian optimization, data compression and automatic model discovery.
机器如何从经验中学习?概率建模为理解学习的本质提供了一个框架,因此已成为设计通过经验获得的数据进行学习的机器的主要理论和实践方法之一。概率框架描述了如何表示和操作关于模型和预测的不确定性,它在科学数据分析、机器学习、机器人技术、认知科学和人工智能中具有核心作用。本文综述介绍了这个框架,并讨论了该领域的一些最新进展,即概率编程、贝叶斯优化、数据压缩和自动模型发现。
