"TensorFlow for Deep Learning (雷扎扎德)1" 本书《TensorFlow for Deep Learning》由Bharath Ramsundar和Reza Bosagh Zadeh合著,旨在带领读者从线性回归到强化学习,全面理解并掌握深度学习中的TensorFlow应用。版权归属作者,由O'Reilly Media, Inc.在美国出版。本书适合教育、商业或销售推广使用,同时也提供在线版本。 在内容方面,书中涵盖了从基础到进阶的各种主题,首先从线性回归开始,这是机器学习中最基本的模型之一,通过这个起点,读者可以了解深度学习的基础概念。线性回归帮助我们理解变量之间的线性关系,并且是理解更复杂模型的基石。 接下来,书中深入探讨了神经网络,这是深度学习的核心。神经网络由多个层次的节点(称为神经元)组成,它们能够处理复杂的数据模式识别任务。书中可能详细介绍了前馈神经网络(Feedforward Neural Networks)、卷积神经网络(Convolutional Neural Networks)和循环神经网络(Recurrent Neural Networks),这些网络在图像识别、自然语言处理等领域有广泛应用。 此外,书中还会涉及深度学习中的优化算法,如梯度下降法、随机梯度下降法(Stochastic Gradient Descent, SGD)及其变种,以及如何避免过拟合的策略,如正则化和dropout技术。 在更高级的主题中,书中会介绍卷积神经网络(CNNs)在图像处理中的应用,包括图像分类和对象检测。CNNs通过其特有的滤波器结构,能够有效地提取图像特征。同时,循环神经网络(RNNs)及其门控变种,如长短期记忆网络(LSTM)在序列数据处理,特别是自然语言处理中发挥着重要作用。 最后,书中提到了强化学习(Reinforcement Learning),这是机器学习的一个分支,其中智能体通过与环境交互来学习最优策略。在强化学习中,TensorFlow可以用于构建和训练Q学习、策略梯度等算法,让智能体在环境中自主学习。 本书的读者应该有一定的数学背景,包括线性代数、概率论和微积分,以便更好地理解深度学习模型的工作原理。同时,熟悉Python编程语言和基础的机器学习概念将有助于阅读和实践书中的示例。 《TensorFlow for Deep Learning》是一本全面介绍深度学习与TensorFlow实战的书籍,它不仅解释了深度学习的理论,还提供了实用的代码示例,帮助读者从入门到精通,实现从简单的线性模型到复杂的强化学习模型的过渡。

Key Features Learn advanced techniques in deep learning with this example-rich guide on Google's brainchildExplore various neural networks with the help of this comprehensive guideAdvanced guide on machine learning techniques, in particular TensorFlow for deep learning. Book Description Deep learning is the next step after machine learning. It is machine learning but with a more advanced implementation. As machine learning is no longer an academic topic, but a mainstream practice, deep learning has taken a front seat. With deep learning being used by many data scientists, deeper neural networks are evaluated for accurate results. Data scientists want to explore data abstraction layers and this book will be their guide on this journey. This book evaluates common, and not so common, deep neural networks and shows how these can be exploited in the real world with complex raw data using TensorFlow. The book will take you through an understanding of the current machine learning landscape then delve into TensorFlow and how to use it by considering various data sets and use cases. Throughout the chapters, you'll learn how to implement various deep learning algorithms for your machine learning systems and integrate them into your product offerings such as search, image recognition, and language processing. Additionally, we'll examine its performance by optimizing it with respect to its various parameters, comparing it against benchmarks along with teaching machines to learn from the information and determine the ideal behavior within a specific context, in order to maximize its performance. After finishing the book, you will be familiar with machine learning techniques, in particular TensorFlow for deep learning, and will be ready to apply some of your knowledge in a real project either in a research or commercial setting.
