CS 4820 develops techniques used in the design and analysis of algorithms, with an emphasis on problems arising in computing applications. Example applications are drawn from systems and networks, artificial intelligence, computer vision, data mining, and computational biology. This course covers four major algorithm design techniques (greedy algorithms, divide and conquer, dynamic programming, and network flow), computability theory focusing on undecidability, computational complexity focusing on NP-completeness, and algorithmic techniques for intractable problems, including identification of structured special cases, approximation algorithms, and randomization.
The goal of this course is to provide you with a high-level exposure to a wide range of Data Science techniques and Machine Learning models. From the basics of getting your Jupyter environment setup, to manipulating and visualizing data, to building supervised and unsupervised models, this class aims to give you the base intuition and skillset to continue developing and working on ML projects. We hope you exit the course with an understanding of how models and optimization techniques work, as well as have the confidence and tools to solve future problems on your own.
Windows Terminal Preview now provides native support of this feature.
The goal of CS2024 is to teach as much of the C++ language as possible with an eye towards your being able to use it effectively in future classes that may depend on it and/or in a professional setting. C++ is ever changing with new standards released every three years. We look to strike a balance between making sure you thoroughly understand “historic” C++ as well as introducing you to new features enabled in the language in the past decade.
