Deep Learning with Python

本暢銷系列作品的第4本書，這次的主題是強化學習。書中延續此系列的一貫風格，顯示實際的程式碼，讓讀者邊執行邊學習，不依賴外部程式庫，從零開始建置、學習支撐強化學習的基本技術與概念。 從「理論」與「實踐」兩方面著手，仔細解說強化學習這個複雜主題的構成要素，讓讀者確實掌握強化學習的獨特理論。有別於只用公式說明理論的書籍，讀者可以從書中的程式碼，獲得許多意想不到的領悟。

本書是《Deep Learning : 用Python進行深度學習的基礎理論實作》的續篇，將延續上一本書，繼續介紹與深度學習有關的技術。本書尤其偏重在自然語言處理及時間序列資料處理上，使用深度學習，挑戰各式各樣的問題。和上一本著作一樣，以「從零開始建構」為概念，詳盡介紹與深度學習有關的先進技術。 簡單來說，自然語言處理是指，讓電腦瞭解我們平常說話內容的技術。事實上，這種自然語言處理技術已經大大改變

Will artificial intelligence usher in a new age of prosperity, or are we sowing the seeds of our own destruction? Some scientists have long feared that AI will lead to human extinction, as ever more ruthless and capable machines elbow us aside. In certain circles it has even become fashionable to stockpile supplies in underground bunkers to prepare for a dystopian future. Optimists argue that AI will be a terrific boon, not least to science and medicine. For instance, MIT researchers have used a deep learning model to identify a chemical compound to treat E. Coli infections. And the 2024 Nobel Prize in Chemistry was awarded to the developers of Google DeepMind for mapping proteins far quicker than previously possible. Toby Walsh has worked in AI since before most people had a computer. In God AI, he guides us with humour and humanity through the claims and the counter-claims – and helps us make up our own minds about one of the biggest issues of our time.
