Data structures play a central role in modern computer science. You interact with data structures much more often than with algorithms (think of Google, your mail server, and even your network routers). In addition, data structures are essential building blocks in obtaining efficient algorithms. This course will cover major results and current directions of research in data structures.

"Analyzing Literary and Cultural References: Identifying the Texts in the Souvenir of Egypt" examines the texts appearing in the imagery of a decorative silk called "Souvenir of Egypt," such as mottos and fragments of verse. The "Souvenir of Egypt" is a piece of ephemera included in the online Travelers in the Middle East Archive (TIMEA). In this module, part 2 of a six part course on the "Souvenir of Egypt," we will search for the meanings of each piece of text independent of and in relation to one another. In the process, we will demonstrate some of the methods used by historian to identify and analyze visual materials and their textual components.

"Analyzing Symbols in Artifacts," section 5 of the 6-part course on "The Souvenir of Egypt," examines the symbols appearing in the imagery of a decorative silk focused on Egypt. Here, we will discuss how to interpret the meaning of each symbol in the silk using a variety of print and online resources. We not only explore the possible meanings of the various symbols, but also explain how to conduct research into cultural history.

Is the beloved paper dictionary doomed to extinction? In this infectiously exuberant talk, leading lexicographer Erin McKean looks at the many ways today's print dictionary is poised for transformation. As the CEO and co-founder of new online dictionary Wordnik, Erin McKean is reshaping not just dictionaries, but how we interact with language itself. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 16-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

This course will provide a gentle introduction to programming using Python™ for highly motivated students with little or no prior experience in programming computers. The course will focus on planning and organizing programs, as well as the grammar of the Python™ programming language. Lectures will be interactive featuring in-class exercises with lots of support from the course staff. This course is offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs from the first week of January until the end of the month.

This course will provide a gentle, yet intense, introduction to programming using Python for highly motivated students with little or no prior experience in programming. The course will focus on planning and organizing programs, as well as the grammar of the Python programming language. The course is designed to help prepare students for 6.01 Introduction to EECS. 6.01 assumes some knowledge of Python upon entering; the course material for 6.189 has been specially designed to make sure that concepts important to 6.01 are covered. This course is offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs from the first week of January until the end of the month.

"Identifying Historical Figures: The Souvenir of Egypt" examines the portraits appearing in the imagery of the decorative silk called "The Souvenir of Egypt," which is collected in the Travelers in the Middle East Archive. Here, we will search for the identity of each person represented in the portraits on the silk using a variety of resources in the library and online. This module is part 4 of a 6-part course on the Souvenir of Egypt.

This module examines the flags appearing in the imagery of the Souvenir of Egypt, a decorative silk that is part of the Travelers in the Middle East Archive. Here, we will search for the identity of each flag using a variety of library and online resources, demonstrating how to identify sometimes obscure images. This module is part 3 of a 6-part course on the Souvenir of Egypt.

Sparse approximation, defined as the practice of representing a given signal as a summation of elements from a dictionary of elementary signals, has traditionally only involved one basis - the canonical basis in which we perceive the world, the Fourier basis that is the foundation of the frequency domain, or the dct basis that is behind the modern JPEG image format. However, recent thought has suggested that more accurate, faster methods for sparse approximation may instead be derived from a "combinational" basis, ie, a basis that consists of two or more bases concatenated onto each other. This resultant basis is often called an "overcomplete" or "redundant" basis, as there are always more vectors in the basis than the magnitude of the dimension of the space they span. Since they are redundant in this effect, the immediate problem would seem to be that there are then an infinite number of representations for any vector, or signal, in a space. Modern theory suggests that there are ideal algorithms for determining these transformations, in terms of number of computations and sparsity of the resultant representation; the two most prevalent being Basis Pursuit (BP) and Orthogonal Matching Pursuit (OMP).

Provides background information on major US publishers of stereographs, including when they were founded and how many stereographs they produced. Provides context for resources in the Travelers in the Middle East Archive (TIMEA). Part 2 of a 4 part course

Our project's goal to test a series of overcomplete dictionaries composed of varied standalone bases on a few standard test images, and then analyze the results. Working towards this, we selected 3 bases and 3 pictures. Our three bases, the fourier basis,

How can researchers take information that they have gathered and build a focused argument about it? This module is part 6 of a 6 part series on researching the background of the Souvenir of Egypt, a textile that is part of the Travelers in the Middle East
