Text Mining (1)

I much enjoyed your text mining course last year and plan to take the deep learning one - thanks for creating it

Text Mining (2)

I like the format of those courses. There is a lot to learn, but it's concentrated on the key points. For somebody working full time it beats a semester-long course.

Dr. Pruim was an outstanding instructor, extremely knowledgeable, respectful and prompt.  This course has given me a strong foundation for continued learning

Visualization in R with ggplot2 (1)

This course has been a life/work changer for me. Within 2 weeks of taking this class, I was able to produce far more informative plots than I ever had before. I'm inspired to take more classes and learn as much as I can about this wonderful…

Visualization in R with ggplot2 (2)

I was very impressed with how well Randall Pruim interacted with the class through the discussion forum.  I also was pleasantly surprised at how smoothly all the logistical "on-line" issues went.  I have already signed up for another course

This course was extremely helpful in facilitating my understanding of programming in R fundamentals.  I feel confident moving forward onto the next section of R programming

R Programming – Introduction Part 1 (2)

This was a great introduction to Programming in R. I feel like I have some basic concepts down and I am looking forward to taking more courses to keep developing my skills in this programming language. I can definitely see the potential for data analysis…

R Programming – Introduction Part 1 (8)

I am working for Scotiabank/International Banking-Marketing (Toronto-Canada). Since we are manipulating tons of data at the customer level for more than 27 countries, R would be the perfect complement tool (we have been using SAS) for customer analytics. I am new on this R world…

Python for Anaytics (2)

In a nutshell of the 13 courses I have completed to date, this is one of the top three in the intellectual excitement it generated, and the very best taught of all.  Prof. Sen has created a jewel of a class,packing an entire semester's…

R Programming – Introduction Part 2 (1)

The course, Introduction to R Programming Part Two, taught by Joris Meys was EXCELLENT! All of the course materials were extremely helpful in allowing me not only to understand the details of R programming but also to gain a solid perspective on the fundamentals of…

R Programming – Introduction Part 2 (4)

I found this course to be very helpful. It wasn't like other courses where you just run example code and change a few things here and there.  I learned a lot and have even applied what I've learned in this course to the other course I'm enrolled in currently.…

R Programming for Statistical Analysis (1)

This course will definitely be used for my work. This course should be called Intro to R for Busy People.   I'm really glad I took this course and will recommend it to others.

R Programming for Statistical Analysis (4)

I am now confident that I can use R and continue learning on my own.  The course also helped me to explore other resources within the R community online.  I'm looking forward to using R in data analysis for my masters thesis and beyond.

Anomaly Detection (3)

As always it was a pleasure taking a course from Professor Indurkhya. This course was a model of what courses can be.

Anomaly Detection (1)

The subject of identifying anomalies is a central task of academic historians, and this course allowed me the welcome luxury to reflect on their nature and methods of discovery.

Anomaly Detection (2)

Using information gleaned from the course concerning a not-well-known distance measure (Gower dissimilarity) useful for cluster models that combine data from mixed variables, including nominal, ordinal, and numeric variables, I was able to refine a model I was working on for an academic conference paper.…

Deep Learning

The two instructors are to be congratulated in putting together a jewel of a short course, one of my very favorite among the many I have taken at  The discussion with such experts was particularly valuable and greatly enhanced the value of the course.…

Natural Language Processing

This course will help me evaluate and code speech recognition tools and develop information extraction models.  It will guide me toward what to consider and keep me from falling into some traps.
