「作者在上市 IC 公司上班，每天面對 real world problems。探索如何建立輕量深度學習網路以及發展更有效率的學習方式是他每天的工作。這是一本學理及實務兼具的好工具書。」 － 中央研究院資訊科學研究所所長 廖弘源博士 推薦[搭起 AI 與統計的橋樑]原本統計學與人工智慧是兩個完全不同的領域，然而兩者在近代都有了新的發展進而產生連結。在人工智慧中導入機率與統計的觀念，讓電腦具有自己找出數據之間的關聯性並試圖解決問題的能力，因而出現機器學習 (machine learning) ，再加上電腦計算能力的大幅提升，解決多層類神經網路和大數據之間聯繫性的可能，進而衍生出現今最熱門的深度學習 (deep learning)。不過，大部分電腦相關科系出身的人並不熟悉統計學，因此在更上一層樓的時候容易遇到障礙。有鑒於此，小編在推出《機器學習的數學基礎》(天瓏專業書店年度暢銷第一名) 一書之後，就積極開發 AI 與統計學相關的書籍。在尋尋覓覓之後請到擅長統計與機器學習的黃志勝博士出馬撰寫《機器學習的統計基礎》，首要之務就是讓讀者不要視統計為畏途，因此在書中設計大量範例以降低學習難度，務求讀得懂、做得出來才容易吸收，進而搭好統計與機器學習的橋樑。如果自覺數學已經還給老師了也不用擔心，可以將本書搭配《機器學習的數學基礎》一併完整學習。[學會統計, 由混亂到清晰]本書從讀者在高中就學過的集合與機率論開始，帶您快速複習一遍，並將容易混淆之處多多舉例說明，並將以前似懂非懂的隨機變數、機率分布等觀念再解釋得更清楚。接下來就進入專有名詞特別多的統計學，這也是造成許多人暈頭轉向之處。特別是樣本估計、信賴區間、顯著水準、信心水準、t-分布、假設檢定...等讓人一個頭兩個大的主題，更是務求清楚明瞭。當然本書不可能把完整的統計學全都搬進來，此處只介紹機器學習、深度學習需要用到的統計基礎知識，縮短您的學習時間。然後就進入機器學習的重頭戲，從資料前處理到迴歸、分類模型的建立，以及當數據的特徵數過多時的 PCA、LDA 統計降維法。從類神經網路開始進入深度學習的範疇，包括前向傳遞、梯度下降法與倒傳遞學習法的手算實作，幫助讀者一步步建立深度學習的演算邏輯，並利用參數常規化解決模型過擬合 (over-fitting) 的問題。最後，導入模型評估，例如二元、多元分類模型評估指標、迴歸模型評估指標、4

An accessible explanation of the technologies that enable such popular voice-interactive applications as Alexa, Siri, and Google Assistant.Have you talked to a machine lately? Asked Alexa to play a song, asked Siri to call a friend, asked Google Assistant to make a shopping list? This volume in the MIT Press Essential Knowledge series offers a nontechnical and accessible explanation of the technologies that enable these popular devices. Roberto Pieraccini, drawing on more than thirty years of experience at companies including Bell Labs, IBM, and Google, describes the developments in such fields as artificial intelligence, machine learning, speech recognition, and natural language understanding that allow us to outsource tasks to our ubiquitous virtual assistants. Pieraccini describes the software components that enable spoken communication between humans and computers, and explains why it's so difficult to build machines that understand humans. He explains speech recognition technology

This Element provides a basic introduction to sentiment analysis, aimed at helping students and professionals in corpus linguistics to understand what sentiment analysis is, how it is conducted, and where it can be applied. It begins with a definition of sentiment analysis and a discussion of the domains where sentiment analysis is conducted and used the most. Then, it introduces two main methods that are commonly used in sentiment analysis known as supervised machine-learning and unsupervised learning (or lexicon-based) methods, followed by a step-by-step explanation of how to perform sentiment analysis with R. The Element then provides two detailed examples or cases of sentiment and emotion analysis, with one using an unsupervised method and the other using a supervised learning method.

This volume tackles a quickly-evolving field of inquiry, mapping the existing discourse as part of placing current developments in historical context; at the same time, breaking new ground in taking on novel subjects and pursuing fresh approaches. The term "A.I." is used to refer to a broad range of phenomena, from machine learning and data mining to artificial general intelligence. The recent advent of more sophisticated AI systems, which function with partial or full autonomy and are capable of tasks which require learning and 'intelligence', presents difficult ethical questions, and has drawn concerns from many quarters about individual and societal welfare, democratic decision-making, moral agency, and the prevention of harm.This work ranges from explorations of normative constraints on specific applications of machine learning algorithms today-in everyday medical practice, for instance-to reflections on the (potential) status of AI as a form of consciousness with attendant rights

In the last few years, Algorithms for Convex Optimization have revolutionized algorithm design, both for discrete and continuous optimization problems. For problems like maximum flow, maximum matching, and submodular function minimization, the fastest algorithms involve essential methods such as gradient descent, mirror descent, interior point methods, and ellipsoid methods. The goal of this self-contained book is to enable researchers and professionals in computer science, data science, and machine learning to gain an in-depth understanding of these algorithms. The text emphasizes how to derive key algorithms for convex optimization from first principles and how to establish precise running time bounds. This modern text explains the success of these algorithms in problems of discrete optimization, as well as how these methods have significantly pushed the state of the art of convex optimization itself.

The twenty-first century has seen a breathtaking expansion of statistical methodology, both in scope and influence. 'Data science' and 'machine learning' have become familiar terms in the news, as statistical methods are brought to bear upon the enormous data sets of modern science and commerce. How did we get here? And where are we going? How does it all fit together? Now in paperback and fortified with exercises, this book delivers a concentrated course in modern statistical thinking. Beginning with classical inferential theories - Bayesian, frequentist, Fisherian - individual chapters take up a series of influential topics: survival analysis, logistic regression, empirical Bayes, the jackknife and bootstrap, random forests, neural networks, Markov Chain Monte Carlo, inference after model selection, and dozens more. The distinctly modern approach integrates methodology and algorithms with statistical inference. Each chapter ends with class-tested exercises, and the book concludes wit

Originally published in 1992, this title reviews seven major subareas in artificial intelligence at that time: knowledge acquisition; logic programming and representation; machine learning; natural la

The rapid development of artificial intelligence technology in medical data analysis has led to the concept of radiomics. This book introduces the essential and latest technologies in radiomics, such as imaging segmentation, quantitative imaging feature extraction, and machine learning methods for model construction and performance evaluation, providing invaluable guidance for the researcher entering the field. It fully describes three key aspects of radiomic clinical practice: precision diagnosis, the therapeutic effect, and prognostic evaluation, which make radiomics a powerful tool in the clinical setting.This book is a very useful resource for scientists and computer engineers in machine learning and medical image analysis, scientists focusing on antineoplastic drugs, and radiologists, pathologists, oncologists, as well as surgeons wanting to understand radiomics and its potential in clinical practice.

This textbook provides future data analysts with the tools, methods, and skills needed to answer data-focused, real-life questions; to carry out data analysis; and to visualize and interpret results to support better decisions in business, economics, and public policy. Data wrangling and exploration, regression analysis, machine learning, and causal analysis are comprehensively covered, as well as when, why, and how the methods work, and how they relate to each other. As the most effective way to communicate data analysis, running case studies play a central role in this textbook. Each case starts with an industry-relevant question and answers it by using real-world data and applying the tools and methods covered in the textbook. Learning is then consolidated by 360 practice questions and 120 data exercises. Extensive online resources, including raw and cleaned data and codes for all analysis in Stata, R, and Python, can be found at www.gabors-data-analysis.com.
