Description: Machine learning is a method of data analysis that automates analytical model building. It is a branch of artificial intelligence (AI) based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention. In this two part seminar you’ll learn the basic machine learning concepts: supervised and unsupervised learning, classification and regression algorithms. This is a two part seminar.

Prerequisites: Basic knowledge of general CS concepts such as data structures, linear algebra and design of algorithm is required.

Description: Text mining, also known as Text Analytics is the process of deriving high-quality information from text. It is the process of examining large collections of written resources to generate new information and to transform the unstructured text into structured data for use in further analysis. In this seminar you’ll learn the basic introduction to text analysis, different steps of text analysis: gathering textual data, cleaning and preparing textual data , analyzing the data (ETL) and visualizing textual data using tools from the HathiTrust Research Center (HTRC).

Prerequisites: Programming background is required. Basic knowledge of general CS concepts such as data structures, linear algebra and design of algorithms is required.
