This text provides deep and comprehensive coverage of the mathematical background for data science, including machine learning, optimal recovery, compressed sensing, optimization, and neural networks. In the past few decades, heuristic methods adopted by big tech companies have complemented existing scientific disciplines to form the new field of Data Science. This text embarks the readers on an engaging itinerary through the theory supporting the field. Altogether, twenty-seven lecture-length chapters with exercises provide all the details necessary for a solid understanding of key topics in data science. While the book covers standard material on machine learning and optimization, it also includes distinctive presentations of topics such as reproducing kernel Hilbert spaces, spectral clustering, optimal recovery, compressed sensing, group testing, and applications of semidefinite programming. Students and data scientists with less mathematical background will appreciate the appendice

A comprehensive update of the leading algorithms text, with new material on matchings in bipartite graphs, online algorithms, machine learning, and other topics.

The dramatic increase in computer performance has been extraordinary, but not for all computations: it has key limits and structure. Software architects, developers, and even data scientists need to understand how exploit the fundamental structure of computer performance to harness it for future applications. Ideal for upper level undergraduates, Computer Architecture for Scientists covers four key pillars of computer performance and imparts a high-level basis for reasoning with and understanding these concepts: Small is fast – how size scaling drives performance; Implicit parallelism – how a sequential program can be executed faster with parallelism; Dynamic locality – skirting physical limits, by arranging data in a smaller space; Parallelism – increasing performance with teams of workers. These principles and models provide approachable high-level insights and quantitative modelling without distracting low-level detail. Finally, the text covers the GPU and machine-learning accelerat

What happens to risk as the economic horizon goes to zero and risk is seen as an exposure to a change in state that may occur instantaneously at any time? All activities that have been undertaken statically at a fixed finite horizon can now be reconsidered dynamically at a zero time horizon, with arrival rates at the core of the modeling. This book, aimed at practitioners and researchers in financial risk, delivers the theoretical framework and various applications of the newly established dynamic conic finance theory. The result is a nonlinear non-Gaussian valuation framework for risk management in finance. Risk-free assets disappear and low risk portfolios must pay for their risk reduction with negative expected returns. Hedges may be constructed to enhance value by exploiting risk interactions. Dynamic trading mechanisms are synthesized by machine learning algorithms. Optimal exposures are designed for option positioning simultaneously across all strikes and maturities.

「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

Optimization techniques are at the core of data science, including data analysis and machine learning. An understanding of basic optimization techniques and their fundamental properties provides important grounding for students, researchers, and practitioners in these areas. This text covers the fundamentals of optimization algorithms in a compact, self-contained way, focusing on the techniques most relevant to data science. An introductory chapter demonstrates that many standard problems in data science can be formulated as optimization problems. Next, many fundamental methods in optimization are described and analyzed, including: gradient and accelerated gradient methods for unconstrained optimization of smooth (especially convex) functions; the stochastic gradient method, a workhorse algorithm in machine learning; the coordinate descent approach; several key algorithms for constrained optimization problems; algorithms for minimizing nonsmooth functions arising in data science; found

An accessible analysis of the new forms of work whose seismic changes will increasingly determine the future of capitalism Automation and the decline in industrial employment have lead to rising fears of a workless future. But what happens when your work itself is the thing that will make your job obsolete? In the past few years, online crowdworking platforms - like Amazon's Mechanical Turk and Clickworker - have become an increasingly important source of work, particularly for those in the Global South. Here, small tasks are assigned to people online, and are often used to train algorithms to spot patterns, patterns through machine learning those same algorithms will then be able to spot more effectively than humans. Used for everything from the mechanics of self-driving cars to Google image search, this is an increasingly powerful part of the digital ecomomy. But what happens to work when it makes itself obsolete. In this stimulating work that blends political economy, studies of con
