Welcome to this course introduction on Coursera on Computational Methods for Data Analysis. My name is Nathan Kutz. I am a professor and chair of applied mathematics at the University of Washington. I'd like to kind of briefly introduce the ideas of what I want to cover in this course so that you would have a better idea of, of how to think about this course. Data, of course, has become ubiquitous in all the sciences, as well as things that are not necessarily considered sciences, such as computer science where you're thinking about data mining applications. But in either case, data is driving revolutions in how we think about managing and analyzing both complex dynamical systems as well as things that are purely data driven, such as market place factors as well as thinking about mining for data bases for important information. This course has a very specific aim which is to integrate many aspects of data analysis in a very broad sense. In the set we're going to start off with, in fact with signal processing and dynamics of signal processing. We're gonna look at thinking about statistical methods, bringing them into these ideas of how to think about time and frequency analysis, and building this forward towards understanding things like dimensionality reduction, and principal component analysis. Also included in this is going to be some kind of idea of thinking about machine learning. How do you think about integrating dynamics? How do you integrate your data collection into teaching a computer to see bigger trends in your data? And in constructing appropriate models that might be able to help you predict future states of your system of interest. This course is an upper division undergraduate, beginning graduate course, so it's fairly high-level. It's expected that you'd have an amazing intro, background in linear algebra. Well, amazing may be a little oversh, pushing but you should have a very good background in linear algebra. You should have a solid background in some computing techniques. here, the course wi ll be mostly based upon Matlab. It's a very fun course, there's lots of great and relevant examples. it will also make you work very hard. so have no illusions about this being easy. It is a very difficult course, but at the end, you'll learn some of those cutting edge techniques being used today in both thinking about data mining applications, but also how you apply this to applications where you might have an underlying physical system of interest and you want to use the data from that system to help you be able to say something very concrete about your system of interest by using data from that system directly in meaningful ways. I hope you enjoy the course, and welcome.
