《Will》不只是名人回憶錄，更是一堂關於情緒掌控與自我成長的課。Will Smith 在書中坦率回顧從饒舌歌手到票房巨星的非凡旅程，也揭露名利背後的孤獨與家庭張力。他反思「意志力」的力量與代價，提醒讀者，推動我們走向成功的燃料，未必能帶我們回到心之所向的家。全書充滿娛樂感與哲理，既有好萊塢幕後的精彩故事，也有普世適用的人生智慧。One of the most dynamic and globally recognized entertainment forces of our time opens up fully about his life, in a brave and inspiring book that traces his learning curve to a place where outer success, inner happiness, and human connection are aligned. Along the way, Will tells the story in full of one of the most amazing rides through the worlds of music and film that anyone has ever had.Will Smith’s transformation from a fearful child in a tense West Philadelphia home to one of the biggest rap stars of his era and then one of the biggest movie stars in Hollywood history, with a string of box office successes that will likely never be broken, is an epic tale of inner transformation and outer triumph, and Will tells it astonishingly well. But it's only half the story. Will Smith thought, with good reason, that he had wo

針對強化學習的關鍵概念和演算法，提供清晰而簡單的說明什麼是強化學習強化學習是學習該做什麼（如何將當前情形映射到動作上），以便最大化一個獎勵訊號數值。學習者不會被告知要採取哪些動作，而是必須透過嘗試來發現哪些動作會產生最大的回報。在最有趣和最具挑戰性的案例中，動作不僅會影響當下的獎勵，同時也會影響下一個情境，並且影響後續所有的獎勵。試誤搜尋和延遲獎勵這兩個特性，是強化學習中的兩個最重要的區別特徵。本

用 Python + Keras 實踐深度學習, 解開神經網路模型的黑盒子在高階函式庫 Keras 的幫助下, 用 6 行程式就可寫一隻深度學習神經網路的程式, 建構深度學習模型就像玩樂高積木一樣, 可以輕易將各種神經網路組合在一起, 而每一種模型可用來解決不同的問題。正宗 Keras 大神著作，正體中文版重磅登場本書為 Keras 之父 François Chollet 親自撰寫, 詳細解說神經

本書的主要目標是，大家一起來「不寫程式，而學AI」。例如不知Python而亦能用TensorFlow。 當今的AI是屬於機器學習(Machine Learning)的一支，基於神經網路( NN: Neural Network)的深度學習。現在，人人都想去理解AI電腦(即機器)到底是如何學習的，以便掌握AI技術熱潮，捷足先登，踏進這項當今的主流產業(AI人工智慧)。 然而，AI機器學習的演算法(Algorithm)又非常依賴於高等數學的運算式，包括線性、非線性函數、N維矩陣(Array)、張量(Tensor)、微分導數、梯度(Gradient)下降、梯度消失等大家很陌生的數學概念和術語。這些複雜性大大阻礙人人親近AI的機會和途徑。俗語說：「面對複雜，唯有簡單」。所以，尋覓和創造一個簡單、親切的途徑，讓人人都能享受，就能彌平進入AI的高大門檻了。Google推出的AI平台：TensorFlow。雖然它還不能完全實踐的美好境界，但可望它是一個不錯的起點了。於是，本書就將Excel試算表與TensorFlow結合起來，就能實現了。不懂程式設計而能學AI，好比不懂車而能學開車。在本書裡，筆者把與分離開來。於是大多數不諳編程技術者，皆能直接切入，而輕鬆愉快地學習AI了。

Who were the artists of the Renaissance? Why do we still learn from Renaissance art? The Renaissance Artists with History Projects for Kids introduces readers ages 10 through 15 to the Italian Renaissance as it was experienced by five of the world’s most renowned artists: Sandro Botticelli, Leonardo da Vinci, Michelangelo, Raphael, and Titian. Kids learn about the biographies of these Renaissance artists through the perspective of three to four major works of art that not only defined that artist’s career but also created a cultural legacy that still resonates in the world today.Renaissance artists were not working and living in a vacuum! Instead, their work was informed by the cultural, historical, and political contexts of their time. Renaissance artists were required to serve lengthy apprenticeships in the busy studios of master artists, learning to make brushes, grind pigments, make fresh plaster, and draw. Plus, they had to maintain membership in guilds and keep in mind the pleasu
