Class 2 is now available


The six lessons for Class 2 are now available on the course website:

https://weka.waikato.ac.nz/dataminingwithweka


Following that, there are 3 weeks to go (classes 3, 4 and 5).
The activities are a crucial part of the course: they're where most people will do their actual learning! However, they do not form part of the assessment, so don't be scared to get wrong answers.

"Data Mining with Weka" has been designed so that participants at many different levels can learn as much as possible – and complete the course successfully. You don't have to do the reading. All you must do to succeed
are the mid-course and final assessments -- which you can try as often as you like. The mid-course assessment will become available this week (24 April) and remain open for the rest of the course. The final assessment will appear during week 5.


cheers, and keep going!

Welcome to "Data Mining with Weka"


Welcome to the course "Data Mining with Weka". The six lessons for Class 1 are now available on the course website

We will release classes 2, 3, 4, and 5 at approximately the same time (Monday noon NZ time) in the upcoming weeks, and send reminder announcements.
The course includes the following resources:
  •  the Weka software; Lesson 1.2 gives downloading instructions (we are using version 3.6.11)
  •  videos, one per lesson, on YouTube
  •  the videos include captions (English and Chinese), which can be turned on in YouTube
  •  we recommend viewing in HD format, again a YouTube control
  •  slides used in the videos (PDF format)
  •  text files containing transcripts of the videos
  •  activities that follow each lesson
  •  access to selected excerpts from Data Mining (3rd Edition) - plus you can buy a discounted copy from the publisher
  •  mid-course assessment (opens  24 April, in Week 2) 
  •  final assessment (opens  15 May, in Week 5)
  •  announcement forumblogtwitter feed (available from the course website)
  •  discussion forum: Teaching Assistants will be available to help you. Primarily this will be in English but some of the Assistants have said they can also help in other languages.

for Chinese participants:
  •  videos on Youku
    • one version with captions in Chinese (another with English captions is available on our Youku channel)

Some notes for participants:
  •  work through the videos and activities at your own pace, in your own time
  •  a new class appears every week; old classes will remain available until the course closes
    •  in theory, you could leave all your learning to the last week (we don't recommend this!)
  • please subscribe to the announcement forum if you haven't already done so: this is the best way to stay up-to-date with the course (click on Membership and email settings to subscribe)
  • only the mid-course and final assessments count towards the Statement of Completion
  •  feel free to install Weka in advance, but please ensure that you have version 3.6.11
  •  if you already know something about Weka, feel free to skip the first class (or two)
  •  during the videos, it may help to follow with Weka on your own computer ("click along with Ian")
  •  the course should take 2–3 hours/week (3–4 hours if you do the optional reading)
  • you can download the materials from http://www.cs.waikato.ac.nz/ml/weka/mooc/dataminingwithweka/
 Please help us by filling out the pre-course survey if you have not already done so.
cheers, and good luck
 Ian

Enrolments open for a new session of Data Mining with Weka


Enrolments have opened for a new session of Data Mining with Weka:


The course will start on 13 April 2015 and extends over 5 weeks. It features:

Class 5 is now available

The lessons for Class 5, the last in our course, are now available on the course website:
https://weka.waikato.ac.nz/moredataminingwithweka

The 6 lessons in Class 5 addresses some important miscellaneous issues. Two are devoted to neural networks, both the simple Perceptron and multilayer Perceptrons — sometimes called “connectionist” models. Then we consider that perennial question, “how much data is enough?”, and show how to answer it using learning curves. Next we look at how to optimise the parameters of learning algorithms, and finally we return to the very beginning and re-visit the ARFF format, including some useful features that haven’t yet been encountered.

The post-course assessment is also now open. The videos, slides and transcripts will remain available at YouTube, Youku and the "Materials" site:

There is also a post-course survey for your opinions of the MOOC.

We aim to run both the introductory course “Data Mining with Weka” and “More Data Mining with Weka” again, but are not sure when. As for a possible third course, “Advanced Data Mining with Weka”, that’s still under consideration: there’s no schedule yet.


Please keep up the help on the course forum -- we greatly value your assistance.

cheers, and enjoy the remainder of the course!

Class 4 is now available

The six lessons for Class 4 are now available on the course website:

https://weka.waikato.ac.nz/moredataminingwithweka

In this class we'll learn about two topics: attribute selection and cost-sensitive classification. Automatic selection of an attribute subset is a powerful way of getting both good results and simpler, easily explainable, models from machine learning; indeed you will end up achieving stunning results with a tiny subset of attributes on a document classification task. And taking the costs of different kinds of error into account is essential in many practical applications.
Next week is the last. Pretty soon you will be an expert in data mining and the use of Weka!

cheers

Class 3 is now available

The six lessons for Class 3 are now available on the course website:

        
https://weka.waikato.ac.nz/moredataminingwithweka

After this week there are 2 weeks to go (classes 4 and 5).

The mid-course assessment is also now available. Do it when you have finished Class 2 (although it will remain open for the rest of the course). The final assessment will appear during week 5.
 
Check your Profile to ensure that your assessment marks have been recorded correctly. Also, check that the name in your Profile is the one you want on your Statement of Completion: as we will use that exact text for the Statements.

My goal is to enable you to learn as much as possible from this course, and I recognize that doing the assessments may not be a priority for you. However, our ability to mount follow-up MOOCs will depend on the success of this one as perceived by my University -- and the number of people who complete it successfully will be a key metric. Thus I urge you to do the assessments for my sake, if not your own :-)

cheers, and keep going! Weeks 3 and 4 are the central part of this course.

Class 2 is now available

The six lessons for Class 2 are now available on the course website:

https://weka.waikato.ac.nz/moredataminingwithweka

The mid-course assessment, following Class 2, is also available. Following that, there are 3 weeks to go (classes 3, 4 and 5).

The activities are a crucial part of the course: they're where most people will do their actual learning! However, they do not form part of the assessment, so don't be scared to get wrong answers. Also, some of the activities are pretty difficult and time-consuming. You don't necessarily need to actually complete them if you find that difficult on your computer, but you do need to understand what it is that you are supposed to do -- and why.

"More Data Mining with Weka" has been designed so that participants at many different levels can learn as much as possible – and complete the course successfully. You don't have to do the reading. All you must do to succeed are the mid-course and final assessments -- which you can try as often as you like. 

The mid-course assessment will remain open for the rest of the course; the final assessment will appear during week 5.

The videos and other course components for Classes 1 and 2 can be downloaded from the "Materials" site, in case you find that more convenient than viewing them online:

cheers, and keep going!
