《数据科学原理(影印版 英文版)》是一部深度探讨数据科学核心概念与实践的权威指南,由Sinan Ozdemir、Sunil Kakade和Marco Tibaldeschi三位作者共同编写。该书的第二版着重于帮助读者理解、分析和预测数据,利用机器学习的概念和工具,让读者能够在复杂问题面前游刃有余。书中内容涵盖了数据科学的完整流程,从数据清洗和准备阶段开始,引导读者逐步构建数学和计算机科学的桥梁,从而成为一名熟练的数据科学家。 本书的核心内容包括但不限于以下几个方面: 1. **数学和编程基础**:通过深入浅出的方式,介绍基本的数学和统计学知识,如概率论、线性代数和统计推断等,这些都是数据科学中的基石。编程方面,可能涉及Python或R等流行语言的基础应用,用于实现数据处理和分析。 2. **数据清洗与预处理**:强调数据质量的重要性,讲解如何处理缺失值、异常值和重复数据,确保数据的准确性。 3. **数据挖掘策略和技术**:介绍数据探索、特征选择、数据转换等技术,帮助读者理解如何从海量数据中提取有价值的信息。 4. **机器学习理论与实践**:这是本书的核心部分,涵盖监督学习、无监督学习、半监督学习和强化学习等各种机器学习算法,以及如何设计和评估模型性能。 5. **统计模型**:书中将介绍一些实用的统计模型,如线性回归、决策树、随机森林和神经网络,以及它们在处理密集型数据集中的应用。 6. **数据可视化**:教学读者如何创建直观的图表和图形,以便有效地传达数据发现,提升数据分析结果的可解释性和吸引力。 7. **版权和法律问题**:书中还提醒读者尊重知识产权,所有内容应在授权范围内使用,避免侵犯版权。 《数据科学原理(影印版 英文版)》不仅适合初学者系统地学习数据科学,也对已有一定基础的专业人士提供了深入理解和实践的平台,帮助他们在数据驱动的世界中做出准确的决策和预测。通过这本书,读者将掌握一套完整的数据科学工具箱,成为数据科学领域的行家里手。

The programme should have the following features: ● A menu including Open and Exit where Open starts a JFileChooser to select the file with the questions inside and Exit ends the programme. ● Once a file is loaded, the GUI should display one question and its answers at a time. ● The user should be able to select an answer and they should be informed if they were correct or not. ● The user should be made aware of the number of correctly answered and the total number of questions answered. ● The user should only be able to proceed to the next question once they answered the current one. ● Once all questions have been answered, the user should be informed of their overall score and that the game has finished. The Open menu item should now be enabled to start a new quiz. Optionally, you can add a restart menu item to redo the current quiz. Concrete sub-tasks: a) define a class called Question to hold a single question, i.e. the text, the possible answers, and the correct answer index; (0.25P) b) write a method to select a file via a JFileChooser and to read all the questions from that file into an array/list of Question objects (assume that file has the structure mentioned above); (0.25P) c) design and implement a GUI with the components mentioned above: A menu, ability to display the question and answers, ability to select an answer, show the outcome and score, and proceed to the next question. (Appropriate layout: 1P, Class extends JFrame: 0.25P, Class follows OOP principles: 0.25P, Global set-up in main method: 0.25P)1 d) write a method to display a question on the GUI you designed; (0.25P) e) implement an actionPerformed method to respond to user interactions with the GUI. Make sure to enable and disable interactive components as required, e.g. the user should not be able to skip to the next question without selecting an answer first and they should not be able to load a new quiz before finishing the current one;
