Why you need to learn digital signal processing.
Nature is mysterious, beautiful, and complex. Trying to understand nature is deeply rewarding, but also deeply challenging. One of the big challenges in studying nature is data analysis. Nature likes to mix many sources of signals and many sources of noise into the same recordings, and this makes your job difficult.
Therefore, one of the most important goals of time series analysis and signal processing is to denoise: to separate the signals and noises that are mixed into the same data channels.
The big idea of DSP (digital signal processing) is to discover the mysteries that are hidden inside time series data, and this course will teach you the most commonly used discovery strategies.
What's special about this course?
The main focus of this course is on implementing signal processing techniques in MATLAB and in Python. Some theory and equations are shown, but I'm guessing you are reading this because you want to implement DSP techniques on real signals, not just brush up on abstract theory.
The course comes with over 10,000 lines of MATLAB and Python code, plus sample data sets, which you can use to learn from and to adapt to your own coursework or applications.
In this course, you will also learn how to simulate signals in order to test and learn more about your signal processing and analysis methods.
You will also learn how to work with noisy or corrupted signals.
Are there prerequisites?
You need some programming experience. I go through the videos in MATLAB, and you can also follow along using Octave (a free, cross-platform program that emulates MATLAB). I provide corresponding Python code if you prefer Python. You can use any other language, but you would need to do the translation yourself.
I recommend taking my Fourier Transform course before or alongside this course. However, this is not a requirement, and you can succeed in this course without taking the Fourier transform course.
What should you do now?
Watch the sample videos, and check out the reviews of my other courses -- many of them are "best-seller" or "top-rated" and have lots of positive reviews. If you are unsure whether this course is right for you, then feel free to send me a message. I hope you to see you in class!

Use your brain to learn signal processing, data analysis, and statistics... by learning about brains!
If you are reading this, I guess you have a brain. Your brain generates electrical signals that can be measured using electrodes, which are like small antennas. These electrical signals are rreeeeeaaallly complicated, because the brain is really complicated!
But learning how to analyze brain electrical signals is an amazing and fascinating way to learn about signal processing, data visualization, spectral analysis, synchronization (connectivity) analyses, and statistics (in particular, permutation-based statistics).
What do you get in this course?
This course contains over 46 hours of video instruction, plus TONS of MATLAB exercises, problem sets, and challenges.
If you do all the MATLAB exercises, this course is easily well over 100 hours of educational content.
And you get access to the Q&A forum, where you can post specific questions about the course material and I answer as quickly as I can (typically 1-2 days).
By the end of this course, you will have confidence in processing, cleaning, analyzing, and performing statistics on brain electrical activity.
What do you need to know before joining this course?
I have tried to make this course accessible to anyone who is interested in learning neural signal processing and time series analysis.
I believe you can simply start this course without any formal background in neuroscience/biology, and without any background in signal processing/math/statistics. That said, some background in these topics will definitely be helpful.
However, I do assume that you have access to MATLAB (or Octave), and that you have some basic MATLAB coding skills (variables, for-loops, basic plotting). If you are a total noob to MATLAB, then please first take an intro-MATLAB course and then come back here.
Why should you trust this weird Mike X Cohen guy?
I've been teaching this material for almost 20 years. I'm really dedicated to teaching and I work really hard to improve my courses each year.
Check out the reviews of this course and my other courses to see what my students think of my teaching style and dedication.
I've also written several textbooks on neural data analysis and scientific programming. And there are more books and more courses on the way!
... but you have to watch out for my weird sense of humor. You've been warned...
PCA & multivariate signal processing, applied to neural data
Learn and apply cutting-edge data analysis techniques for the age of "big data" in neuroscience (theory and MATLAB code)

What is this course all about?
Neuroscience (brain science) is changing -- new brain-imaging technologies are allowing increasingly huge data sets, but analyzing the resulting Big Data is one of the biggest struggles in modern neuroscience (if don't believe me, ask a neuroscientist!).
The increases in the number of simultaneously recorded data channels allows new discoveries about spatiotemporal structure in the brain, but also presents new challenges for data analyses. Because data are stored in matrices, algorithms developed in linear algebra are extremely useful.
The purpose of this course is to teach you some matrix-based data analysis methods in neural time series data, with a focus on multivariate dimensionality reduction and source-separation methods. This includes covariance matrices, principal components analysis (PCA), generalized eigendecomposition (even better than PCA!), and independent components analysis (ICA). The course is mathematically rigorous but is approachable to individuals with no formal mathematics background. MATLAB is the primary numerical processing engine but the material is easily portable to Python or any other language.
You should take this course if you are a...
neuroscience researcher who is looking for ways to analyze your multivariate data.
student who wants to be competitive for a neuroscience PhD or postdoc position.
non-neuroscientist who is interested in learning more about the big questions in modern brain science.
independent learner who wants to advance your linear algebra knowledge.
mathematician, engineer, or physicist who is curious about applied matrix decompositions in neuroscience.
person who wants to learn more about principal components analysis (PCA) and/or independent components analysis (ICA)
intrigued by the image that starts off the Course Preview and want to know what it means! (The answers are in this course!)
Unsure if this course is right for you?
I worked hard to make this course accessible to anyone with at least minimal linear algebra and programming background. But this course is not right for everyone. Check out the preview videos and feel free to contact me if you have any questions.
I look forward to seeing you in the course!
