"深入理解MATLAB中的深度学习:构建智能未来" 在当今的IT领域,深度学习作为一种强大的机器学习技术,正日益崭露头角。"Introducing Deep Learning with MATLAB"这一教程聚焦于如何利用MATLAB这个强大的工具平台来实现深度学习的应用。深度学习的核心在于其神经网络架构,这种网络通过多层结构进行学习,每层负责处理输入数据的不同抽象层次,从而提高模型对复杂任务的理解能力。 "Deep"一词的含义在于网络的深度,即包含的层数越多。传统神经网络通常由两到三层组成,而现代的深度网络可以扩展到数百层,这样的设计允许模型捕获更深层次的特征,从而在图像分类、文本分析(如语音识别和翻译)、人脸识别等任务中展现出卓越性能。例如,一个自动驾驶车辆能准确识别行人过街,ATM可以鉴别伪钞,智能手机应用能即时翻译异国文字,这些都是深度学习在实际场景中的体现。 深度学习特别适合于识别类任务,如面部识别、文本翻译和语音识别,以及高级驾驶辅助系统中的关键功能,如车道分类和交通标志识别。这些应用广泛且深入人们日常生活,展示了深度学习在推动科技发展和社会智能化方面的巨大潜力。 MATLAB作为一个流行的编程环境,提供了丰富的工具和库来简化深度学习的开发过程。它支持神经网络的设计、训练、优化和评估,使得研究人员和开发者能够快速构建和测试复杂的深度学习模型。UCLA的研究人员利用MATLAB进行深度学习研究,这表明MATLAB已经成为深度学习实践者和学者的首选工具之一。 "Introducing Deep Learning with MATLAB"是一份宝贵的资源,它不仅介绍了深度学习的基本概念,还展示了如何利用MATLAB这个平台进行实际操作,使读者能够掌握这一前沿技术,并将其应用于各自的工作和项目中,推动科技的进步与创新。

This book consists of six chapters, which can be grouped into three subjects. The first subject is Machine Learning and takes place in Chapter 1. Deep Learning stems from Machine Learning. This implies that if you want to understand the essence of Deep Learning, you have to know the philosophy behind Machine Learning to some extent. Chapter 1 starts with the relationship between Machine Learning and Deep Learning, followed by problem solving strategies and fundamental limitations of Machine Learning. The detailed techniques are not introduced yet. Instead, fundamental concepts that applies to both the neural network and Deep Learning will be covered. The second subject is artificial neural network. Chapters 2-4 focuses on this subject. As Deep Learning is a type of Machine Learning that employs a neural network, the neural network is inseparable from Deep Learning. Chapter 2 starts with the fundamentals of the neural network: principles of its operation, architecture, and learning rules. It also provides the reason that the simple single-layer architecture evolved to the complex multi-layer architecture. Chapter 3 presents the backpropagation algorithm, which is an important and representative learning rule of the neural network and also employed in Deep Learning. This chapter explains how cost functions and learning rules are related and which cost functions are widely employed in Deep Learning. Chapter 4 introduces how to apply the neural network to classification problems. We have allocated a separate section for classification because it is currently the most prevailing application of Machine Learning. For example, image recognition, one of the primary applications of Deep Learning, is a classification problem. The third topic is Deep Learning. It is the main topic of this book as well. Deep Learning is covered in Chapters 5 and 6. Chapter 5 introduces the drivers that enables Deep Learning to yield excellent performance. For a better understanding, it starts with the history of barriers and solutions of Deep Learning. Chapter 6 covers the convolution neural network, which is representative of Deep Learning techniques. The convolution neural network is second-to-none in terms of image recognition. This chapter starts with an introduction of the basic concept and architecture of the convolution neural network as it compares with the previous image recognition algorithms. It is followed by an explanation of the roles and operations of the convolution layer and pooling layer, which act as essential components of the convolution neural network. The chapter concludes with an example of digit image recognition using the convolution neural network and investigates the evolution of the image throughout the layers.
