"El crecimiento en el uso de la ciencia de datos en nuestras sociedades est impulsado por la aparici n del big data y las redes sociales, la aceleraci n de la potencia inform tica, la reducci n masiva en el costo de la memoria de la computadora y el desarrollo de m todos m s potentes para el an lisis y modelado de datos, como el aprendizaje profundo. Todos estos factores juntos hacen que nunca haya sido tan f cil para las organizaciones recopilar, almacenar y procesar datos. Al mismo tiempo, estas innovaciones t cnicas y la aplicaci n m s amplia de la ciencia de datos hacen que los desaf os ticos relacionados con el uso de datos y la privacidad individual nunca han sido tan apremiantes."

Datatiede on nopeasti kehittyvä ala, joka yhdistää monien eri alojen ongelmat, algoritmit ja aineiston analyysissa käytetyt mentelmät tavoitteenaan eristää (suur)aineistosta arvokasta tietoa. Informaatiotekniikan ja sosiaalisen median kehityksen seurauksena aineistoa kerätään nyt enemmän kuin koskaan ja sitä käytetään moniin tarkoituksiin. Datatiede liittyy läheisesti koneoppimiseen, tilastotieteeseen, aineiston eettiseen käyttöön ja sen käytön sääntelyyn ja suurteholaskentaan, kaikki tällä hetkellä erittäin tärkeitä yhteiskunnallisia kysymyksiä. Datatiede on ensimmäinen suomenkielinen kirja, joka esittelee alan ja sen haasteet jokaiselle ymmärrettävällä tavalla. John D. Kelleher on Dublinin teknillisen korkeakoulun tietotekniikan professori ja sen Informaatio-, viestintä- ja viihdetutkimuksen laitoksen akateeminen johtaja. Suomeksi häneltä on aikaisemmin ilmestynyt teos Syväoppiminen. Brendan Tierney on saman yliopiston luennoija ja useiden tiedonlouhintaa käsittelevän kirjan tekijä.

Machine learning is often used to build predictive models by extracting patterns from large datasets. These models are used in predictive data analytics applications including price prediction, risk assessment, predicting customer behavior, and document classification. This introductory textbook offers a detailed and focused treatment of the most important machine learning approaches used in predictive data analytics, covering both theoretical concepts and practical applications. Technical and mathematical material is augmented with explanatory worked examples, and case studies illustrate the application of these models in the broader business context. This second edition covers recent developments in machine learning, especially in a new chapter on deep learning, and two new chapters that go beyond predictive analytics to cover unsupervised learning and reinforcement learning. The book is accessible, offering nontechnical explanations of the ideas underpinning each approach before introducing mathematical models and algorithms. It is focused and deep, providing students with detailed knowledge on core concepts, giving them a solid basis for exploring the field on their own. Both early chapters and later case studies illustrate how the process of learning predictive models fits into the broader business context. The two case studies describe specific data analytics projects through each phase of development, from formulating the business problem to implementation of the analytics solution. The book can be used as a textbook at the introductory level or as a reference for professionals.

Syväoppiminen on tekoälyn ydin, ja tekoälyyn perustuvat tietokoneet opetetaan syväoppivilla tekniikoilla. Syväoppimisen tulokset ovat olleet häkellyttäviä. Siihen perustuvat koneet ovat päihittäneet peleistä vaikeimpana pidetyn go:n mestarit vain muutamassa vuodessa ja ne oppivat tietokonepelit nopeammin ja paremmin kuin ihmiset. Sama vahvuus ilmenee myös muilla ihmiselämän aloilla. Syväoppiminen on ensimmäinen syväoppimisen yleistajuisesti suomen kielellä kuvaava teos. Se esittelee alan käsitteet, tilan ja mahdollisen tulevaisuuden.

An accessible introduction to the artificial intelligence technology that enables computer vision, speech recognition, machine translation, and driverless cars. Deep learning is an artificial intelligence technology that enables computer vision, speech recognition in mobile phones, machine translation, AI games, driverless cars, and other applications. When we use consumer products from Google, Microsoft, Facebook, Apple, or Baidu, we are often interacting with a deep learning system. In this volume in the MIT Press Essential Knowledge series, computer scientist John Kelleher offers an accessible and concise but comprehensive introduction to the fundamental technology at the heart of the artificial intelligence revolution. Kelleher explains that deep learning enables data-driven decisions by identifying and extracting patterns from large datasets; its ability to learn from complex data makes deep learning ideally suited to take advantage of the rapid growth in big data and computational power. Kelleher also explains some of the basic concepts in deep learning, presents a history of advances in the field, and discusses the current state of the art. He describes the most important deep learning architectures, including autoencoders, recurrent neural networks, and long short-term networks, as well as such recent developments as Generative Adversarial Networks and capsule networks. He also provides a comprehensive (and comprehensible) introduction to the two fundamental algorithms in deep learning: gradient descent and backpropagation. Finally, Kelleher considers the future of deep learning—major trends, possible developments, and significant challenges.

A concise introduction to the emerging field of data science, explaining its evolution, relation to machine learning, current uses, data infrastructure issues, and ethical challenges. The goal of data science is to improve decision making through the analysis of data. Today data science determines the ads we see online, the books and movies that are recommended to us online, which emails are filtered into our spam folders, and even how much we pay for health insurance. This volume in the MIT Press Essential Knowledge series offers a concise introduction to the emerging field of data science, explaining its evolution, current uses, data infrastructure issues, and ethical challenges. It has never been easier for organizations to gather, store, and process data. Use of data science is driven by the rise of big data and social media, the development of high-performance computing, and the emergence of such powerful methods for data analysis and modeling as deep learning. Data science encompasses a set of principles, problem definitions, algorithms, and processes for extracting non-obvious and useful patterns from large datasets. It is closely related to the fields of data mining and machine learning, but broader in scope. This book offers a brief history of the field, introduces fundamental data concepts, and describes the stages in a data science project. It considers data infrastructure and the challenges posed by integrating data from multiple sources, introduces the basics of machine learning, and discusses how to link machine learning expertise with real-world problems. The book also reviews ethical and legal issues, developments in data regulation, and computational approaches to preserving privacy. Finally, it considers the future impact of data science and offers principles for success in data science projects.
