In this module, we examine network theory, equipping you with a foundational understanding of nodes, edges, and graphs. We will explore various network types, from social networks to keyword co-occurrence networks, learning to discern their relevance in diverse domains. Practical application includes extracting and creating keyword co-occurrence networks from text data through preprocessing, keyword identification, and relationship construction. You will then analyze these networks, employing measures like centrality and community detection, enhancing your ability to interpret results. This module culminates in the extraction of meaningful insights, enabling you to identify keywords and thematic clusters within textual data through the lens of network analysis.

In this module, you will inspect the intricate world of joint probability distributions. You will develop the skill to identify and interpret these distributions, employing probability mass functions (PMFs) for discrete variables and probability density functions (PDFs) for continuous variables. This module will further equip you with the capability to calculate and interpret marginal probability distributions, involving the summing or integrating of variables within a joint distribution. The theoretical insights and practical calculations will help you gain a complete understanding of the relationships between variables and the nuanced exploration of joint, marginal, and conditional probability distributions.

In this module, you will explore the fundamental concept of mathematical expectation, or expected value, in probability theory. Through theory and practice, you will calculate the expected value for both discrete and continuous random variables, gaining insights into its significance as a measure of central tendency. We will also explore the statistical concepts of covariance and correlation, guiding participants in the calculation of coefficients to quantify relationships between pairs of random variables. Interpretation of these results allows you to classify the degree and direction of association through positive, negative, or zero covariance/correlation values. Additionally, the module addresses the concept of independence, elucidating its relationship with zero covariance and correlation.

常见问题
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
