Machine Learning and Data Mining

  • Jan 25, 2014 · 2:00 PM
  • This location is shown only to members

Session on Machine Learning and Data Mining.

The session will be run by Erik Linstead  who is a faculty member at Chapman and a software engineer at Boeing.  Here is his description:


"As the size of data repositories continues to grow, so does the need for mathematically-grounded tools and techniques for building models to succinctly describe the patterns found within them. In this session we provide an overview of the theory and practice of mining big data. Attendees will be introduced to the essential concepts of supervised and unsupervised machine learning, and have a chance to apply common data mining algorithms to real data sets using tools such as Weka. Advanced techniques such as kernel methods and deep learning will also be surveyed as time allows."


Weka is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. Weka can be installed on Windows, OS/X or Linux so I hope everyone can install it on their laptops before the meetup.  We can then spend our time doing actual data mining rather than just configuring software.

Download and install Weka, for free, before you come to the meetup.

    This was one of the BEST meetups I have been to. Big thanks to Dr. Erik Linstead for giving more of an overview about the principles of Data mining rather than just showing us Weka.

    Hello Michael, I am aware that RSVP is closed for this event. Please let me know if I can still attend the session. I am interested in attending the event.

    Thank you.

      OK, as long as you bring a laptop with Weka installed!

    Will miss everyone this weekend! I wanted to invite everyone to join us at SCALE 12x ( So Cal Linux Expo ) on Feb 21, 22,[masked] at the LAX Hilton. On Sunday the 23rd we will have a big data track, 4 sessions on Big Data. SCALE is a great community run conference so please do join us. https://www.socallinuxexpo.org/blog/scale-12x

    Sadly, something came up and I won't be able to make it, so I freed my spot for someone else. I hope to make it to a future meeting.

      Thanks for letting us know. I hope to see you at the next one.

    Jagan asked "what are the pre-requisites for this meet up? "

    My reply: You must install Weka on a laptop and bring it to the meetup.

    You should have a background in mathematics and statistics that includes vectors and matrices.

    I have a +1. Is that okay?

    I would love to be there to meet everyone. Unfortunately, I won't be able to make it this time.

    I'm have downloaded Weka[masked] for MacOSX with Java 1.7. When I launch the app, all the dialog windows and interfaces seem to open OK.

    One item I have a question on: When I type CTRL+L and bring up the Log Window the log has 5 error messages in it related to JDBC database drivers not being found in the Java Classpath. Is this normal?

    Trying to add database driver (JDBC): RmiJdbc.RJDriver - Error, not in CLASSPATH?
    Trying to add database driver (JDBC): jdbc.idbDriver - Error, not in CLASSPATH?
    Trying to add database driver (JDBC): org.gjt.mm.mysql.Driver - Error, not in CLASSPATH?
    Trying to add database driver (JDBC): com.mckoi.JDBCDriver - Error, not in CLASSPATH?
    Trying to add database driver (JDBC): org.hsqldb.jdbcDriver - Error, not in CLASSPATH?

      Linux Mint 13 and Java 1.6 (OpenJDK) has the same messages. See Weka maintainers reponse: http://weka.8497.n7.n...­

      January 20, 2014

    • Michael F.

      Weka automatically searches for JDBC drivers so that it can automatically import from databases. We will not be using any external databases for the Saturday workshop so these messages are irrelevant for what we will be doing on Saturday.

    Quick question, there are 2 OS x versions of Weka available. Any preference? Does it matter which one we download and install?

      The first one works (needs you to update Zoe have Java1.7). The second link based on Java 1.6 says it's corrupt after download.

      January 20, 2014

    • David K.

      I agree with Kumar. I had already put Java 1.7 on my Mac, so I went with the top download link, and it is working fine when I launch it.

      I kept it local to my user and just copied the App (& its associated resource folder) to a new folder in my environment (vs. drag-n-drop into the System "Applications"­ Folder).

    This sounds terrific. I am looking forward to hearing more
