COS424 - Fundamentals of Machine Learning (Spring)

Computers have made it possible, even easy, to collect vast amounts of data from a wide variety of sources. It is not always clear, however, how to use those data, and how to extract useful information from them. This problem is faced in a tremendous range of business and scientific applications. This course will focus on some of the most useful approaches to the problem of analyzing large complex data sets, exploring both theoretical foundations and practical applications. Students will gain experience analyzing several types of data, including text, images, and biological data.

COS435 - Information Retrieval, Discovery, and Delivery

This course examines the methods used to gather, organize and search for information in large digital collections (e.g. web search engines). We study classic techniques of indexing documents and searching text and also new algorithms that exploit properties of the Web (e.g. links) social networks and other digital collections, including multimedia collections. Techniques include those for relevance and ranking of documents, exploiting user history, and information clustering. We also examine systems aspects of search technology: how distributed computing and storage are used to make information delivery efficient.

Classes: Two 90-minute lectures.
Prerequisite(s): COS226 and MAT 202.

COS436 - Human-Computer Interface Technology (Fall)

Creating technologies that fit into people's everyday lives involves more than having technically sophisticated algorithms, systems, and infrastructure. It involves understanding how people think and behave and using this info. to design user-facing interfaces that enhance and augment human capabilities. You will be introduced to the field of human-computer interaction and the tools, techniques, and principles that guide research on people. Design and implement user-facing systems that bring joy rather than frustrate the user and put these skills into practice in a semester long group project involving the creation of an interactive system.

Classes: Three lectures.
Prerequisite(s): COS 217 and 226.

COS448 - Innovating Across Technology, Business, and Marketplaces (Spring)

Course teaches engineering students about issues tackled by leading Chief Technology Officers: the technical visionaries and/or managers who innovate at the boundaries of technology and business by understanding both deeply, and who are true partners to the CEO, not just implementers of business goals. Focus will be on thinking like a CTO (of a startup and a large company) from technology and business perspectives, and on software and Internet-based businesses. Industry-leading guest speakers provide perspectives too.
