作业完成的原则:署你名字的工作必须是你个人的贡献。在完成作业的过程中,允许讨论,前提是讨论的所有参与者均处于同等完成度。但关键想法的执行、以及作业文本的写作必须独立完成,并在作业中致谢(acknowledge)所有参与讨论的人。符合规则的讨论与致谢将不会影响得分。不允许其他任何形式的合作——尤其是与已经完成作业的同学“讨论”。 | |||
本课程将对剽窃行为采取零容忍的态度。在完成作业过程中,对他人工作(出版物、互联网资料、其他人的作业等)直接的文本抄袭和对关键思想、关键元素的抄袭,按照 [http://www.acm.org/publications/policies/plagiarism_policy ACM Policy on Plagiarism]的解释,都将视为剽窃。剽窃者成绩将被取消。如果发现互相抄袭行为,<font color=red> 抄袭和被抄袭双方的成绩都将被取消</font>。因此请主动防止自己的作业被他人抄袭。 | 本课程将对剽窃行为采取零容忍的态度。在完成作业过程中,对他人工作(出版物、互联网资料、其他人的作业等)直接的文本抄袭和对关键思想、关键元素的抄袭,按照 [http://www.acm.org/publications/policies/plagiarism_policy ACM Policy on Plagiarism]的解释,都将视为剽窃。剽窃者成绩将被取消。如果发现互相抄袭行为,<font color=red> 抄袭和被抄袭双方的成绩都将被取消</font>。因此请主动防止自己的作业被他人抄袭。 | ||

Syllabus
课程内容分为三大部分:
- 经典概率论:概率空间、随机变量及其数字特征、多维与连续随机变量、极限定理等内容
- 概率与计算:测度集中现象 (concentration of measure)、概率法 (the probabilistic method)、离散随机过程的相关专题
- 数理统计:参数估计、假设检验、贝叶斯估计、线性回归等统计推断等概念
对于第一和第二部分,要求清楚掌握基本概念,深刻理解关键的现象与规律以及背后的原理,并可以灵活运用所学方法求解相关问题。对于第三部分,要求熟悉数理统计的若干基本概念,以及典型的统计模型和统计推断问题。
经过本课程的训练,力求使学生能够熟悉掌握概率的语言,并会利用概率思维来理解客观世界并对其建模,以及驾驭概率的数学工具来分析和求解专业问题。

学术诚信 Academic Integrity
学术诚信是所有从事学术活动的学生和学者最基本的职业道德底线,本课程将不遗余力的维护学术诚信规范,违反这一底线的行为将不会被容忍。
作业完成的原则:署你名字的工作必须是你个人的贡献。在完成作业的过程中,允许讨论,前提是讨论的所有参与者均处于同等完成度。但关键想法的执行、以及作业文本的写作必须独立完成,并在作业中致谢(acknowledge)所有参与讨论的人。符合规则的讨论与致谢将不会影响得分。不允许其他任何形式的合作——尤其是与已经完成作业的同学“讨论”。
本课程将对剽窃行为采取零容忍的态度。在完成作业过程中,对他人工作(出版物、互联网资料、其他人的作业等)直接的文本抄袭和对关键思想、关键元素的抄袭,按照 ACM Policy on Plagiarism的解释,都将视为剽窃。剽窃者成绩将被取消。如果发现互相抄袭行为, 抄袭和被抄袭双方的成绩都将被取消。因此请主动防止自己的作业被他人抄袭。
学术诚信影响学生个人的品行,也关乎整个教育系统的正常运转。为了一点分数而做出学术不端的行为,不仅使自己沦为一个欺骗者,也使他人的诚实努力失去意义。让我们一起努力维护一个诚信的环境。
