课程描述
课程编号:511012Y 课程属性:学科基础课 学时/学分:40/2 预修课程:分子生物学、遗传学、统计学、C语言 教学目的和要求: 生物信息学是利用数学模型和计算机程序对生物学研究中产生的数据进行分 析计算并得出结论和产生新的科学假说的一种科研手段。通过本课程的教授, 使得学生能够: • 懂得生物学中有哪些数学问题,数学模型和数学手段; • 利用数据库技术、计算机编程和网页工具来进行基本的生物信息学分析; • 掌握核酸和蛋白质序列分析的基本技能; • 懂得如何从芯片和其他高通量技术产生的数据来构建基因调控网络; • 本课程的开设要求学生有分子生物学、遗传学、统计学及C语言的基础知识 和技能,更重要的是要求学生要努力培养自己利用数学模型和逻辑思维来思 考和解决生物学问题。本课程为生物学各专业博士、硕士研究生的学科基础 课,同时也可作为数理、计算机等相关学科研究生的选修课。本课程的考核 方式为大作业和期末考试,比例为50%:50%。

What do you mean by biology?
Statistical inference
• Statistical inference is the process of making conclusions using data that is subject to random variation, for example, observational errors or sampling variation.
Reasoning, Logic, Argument
• Reasoning is the cognitive process of looking for reasons, beliefs, conclusions, actions or feelings. • Logic is the study of reasoning. • An argument is a set of one or more meaningful declarative sentences (or "propositions") known as the premises along with another meaningful declarative sentence (or "proposition") known as the conclusion. • One approach to the study of reasoning is to identify various forms of reasoning that may be used to support or justify conclusions. The main division between forms of reasoning that is made in philosophy is between deductive reasoning and inductive reasoning. Formal logic has been described as "the science of deduction". The study of inductive reasoning is generally carried out within the field known as informal logic or critical thinking.
Deductive reasoning
• Premise 1: All humans are mortal. • Premise 2: Socrates is a human. • Conclusion: Socrates is mortal.
Inductive reasoning
• Premise: The sun has risen in the east every morning up until now. • Conclusion: The sun will also rise in the east tomorrow.
