摘要:

贝叶斯核方法的表达能力使其成为人工智能许多不同方面的重要工具,并对大量现代应用领域非常有用,通过不确定性分析提供了强大的功能和可解释性。本文介绍和讨论了两种方法,跨越概率贝叶斯方案和回归核方法的领域:高斯过程和相关向量机。我们的重点是开发一个共同的框架,以查看这些方法,通过中间方法的概率版本的著名的内核岭回归,并绘制它们之间的连接,通过双配方,并讨论其应用程序的背景下,主要任务:回归,平滑,插值和过滤。总的来说,我们提供了这些模型背后的数学概念的理解,我们总结和深入讨论不同的解释,并强调与其他方法的关系,如线性核平滑,卡尔曼滤波和傅立叶近似。在整个过程中,我们提供了许多数字,以促进理解,我们提出了许多建议,以从业人员。不同技术的优点和缺点突出。据我们所知,这是迄今为止针对这两种方法的最深入的研究,并且将与整个数据科学,信号处理,机器学习和人工智能领域的理论理解和实践者相关。

英文摘要:

The expressive power of Bayesian kernel-based methods has led them to become an important tool across many different facets of artificial intelligence, and useful to a plethora of modern application domains, providing both power and interpretability via uncertainty analysis. This article introduces and discusses two methods which straddle the areas of probabilistic Bayesian schemes and kernel methods for regression: Gaussian Processes and Relevance Vector Machines. Our focus is on developing a common framework with which to view these methods, via intermediate methods a probabilistic version of the well-known kernel ridge regression, and drawing connections among them, via dual formulations, and discussion of their application in the context of major tasks: regression, smoothing, interpolation, and filtering. Overall, we provide understanding of the mathematical concepts behind these models, and we summarize and discuss in depth different interpretations and highlight the relationship to other methods, such as linear kernel smoothers, Kalman filtering and Fourier approximations. Throughout, we provide numerous figures to promote understanding, and we make numerous recommendations to practitioners. Benefits and drawbacks of the different techniques are highlighted. To our knowledge, this is the most in-depth study of its kind to date focused on these two methods, and will be relevant to theoretical understanding and practitioners throughout the domains of data-science, signal processing, machine learning, and artificial intelligence in general.
