## Network Analysis and Network Optimization in SAS ViyaThis course provides a set of algorithms to perform both network analysis and network optimization. Practical demonstrations and exercises emphasize the theory, and business case studies illustrate the possible outcomes from such techniques. Hands-on activities are based on the NETWORK and OPTNETWORK procedures in SAS Viya. Network analysis includes graph theory algorithms that can augment data mining and machine learning. In many practical applications, pairwise interaction between the entities of interest in the model often plays an important role. Network analysis goes beyond traditional clustering and predictive models to identify patterns in business data, including entities’ behavior based on their relationships. Network analysis can be employed to avoid churn, diffuse products and services, detect fraud and abuse, identify anomalies, and many other applications, in a wide range of industries such as communications and media, banking, insurance, retail, utilities, and travel and transportation. Network optimization includes graph theory algorithms that can augment more generic mathematical optimization approaches. Many practical applications of optimization depend on an underlying network. Networks also appear explicitly and implicitly in many other application contexts. Networks are often constructed from certain natural co-occurrence types of relationships, such as relationships among researchers who coauthor articles, actors who appear in the same movie, words or topics that occur in the same document, items that appear together in a shopping basket, terrorism suspects who travel together or are seen in the same location, and so on. In these types of relationships, the strength or frequency of interaction is modeled as weights on the links of the resulting network. Aprenda a
- Identify the type of the data to create the nodes and roles in a network perspective, as well as the possible links between them.
- Define the weights for nodes and links and the methods to build a network on the available data, considering the distinct importance of nodes and links and their behavior in relation to each other.
- Recognize the different types of groups of nodes based on their relationships within the network, such as communities, connected components, biconnected components, core, and reach networks.
- Compute the network metrics such as degree, influence, closeness, betweenness, hub, authority, eigenvector, and clustering coefficient to analyze and describe the network.
- Perform network optimization based on a set of algorithms such as clique, cycle, shortest path, minimum-cost network flow, linear assignment, minimum spanning tree, minimum link-weight cut, transitive closure, and traveling salesman problem.
- Apply network analysis and network optimization to solve business problems in different industries.
