First day handout (syllabus that is specific to this semester).

KU Campus Mask policy: Resident students must wear a mask anytime they are outside of their personal room and within a building or with anyone else but their roommate. Commuter students must wear a mask anytime they are on campus within a building or with anyone. The course is 100% via Zoom at class time. I will record & post class videos, but want you there at class time.

PA: The Secretary's Order requires individuals to wear a face covering, in both indoor public places and in the outdoors when they are not able to consistently maintain social distancing from individuals who are not members of their household, such as on a busy sidewalk, waiting in line to enter a place, or near others at any place people are congregating. Whether inside in a public place or outside, and when wearing a face covering or not, everyone should socially distance at least 6 feet apart from others who are not part of your household.


Windows users can download the WinSCP file transfer client in the Computer Science sub-menu below here.  Textbook: Data Mining: Practical Machine Learning Tools and Techniques, Fourth Edition, Witten, et. al., ISBN 978-0128042915. You can buy a discounted copy of the 3rd Edition at the KU Book Store -- either edition is fine. I have put a copy of the 3rd edition of the textbook on reserve in Rohrbach Library. You can go to the front desk & borrow it overnight.

I commit to using each student's preferred name and preferred gender pronoun. Feel free to contact me in private if I make mistakes in pronunciation, name, gender, or anything else. Thanks! Here is a poll to which you can reply privately on paper or via email.

Gender-Based Crimes
Educators must report incidents of gender-based crimes, including sexual assault, sexual harassment, stalking, dating violence, and domestic violence.  If a student discloses such incidents to me during class or in a course assignment, I am not required to report the disclosure, unless the student was a minor at the time the incident occurred.  Regardless of the student’s age, if the incident is disclosed to me outside the classroom setting or a course assignment, I am required by law to report the disclosure, including relevant details, such as the names of those involved in the incident, to Public Safety and Police Services and to Mr. Jesus Peña, Title IX Coordinator.
Jesus A. Peña, Esq.
Deputy to the President for Compliance, Equity & Legal Affairs

There is a 10% per late late penalty for projects that come in after the due date. There will be a 10% deduction from a homework assignment for repeated web surfing, web-based chatting or other use of the Internet for activities unrelated to class activities during both lectures and working sessions. During a working session you may leave after completing and turning in all due work; you are encouraged to stay to get additional practice and ask questions. Thank you.
RESOURCES & HANDOUTS. We will use research results published by students & me to discuss various topics.

Here are textbook slides from Kotu’s & Deshpande’s Predictive Analytics and Data Mining: Concepts and Practice using RapidMiner.
    I found this book at start of semester, will probably use it next time I teach the course.
    It is at a more appropriate level for the course, but the slides from all 3 textbooks cited on this page stink.
    However, I will use the slides from this book, with my own additions, since they are generally better.
    I adapted slides for Linear Regression and M5P Trees, 10/30/2017.

There is an excellent on-line video course Predictive Analytics Training with Weka (Introduction) by one of our textbook authors & Weka creators.

Here is our textbook's website. We will be using the Weka tool set, which you can download to your machine from here.
    The PDF Appendix to our textbook is here. It is a 128-page tutorial on using Weka. Here is the Weka Wiki.
    I will draw some material from this textbook as well.

The Weka download page has this note:
If your computer has a display that has a high pixel density, and you are using Windows, Weka's user interfaces may not be scaled appropriately and appear tiny. Installing Java 9 or later solves this problem. Alternatively, in the Program menu of Weka's GUIChooser, go into Settings, and select WindowsLookAndFeel from the "Look and feel for UI" dropdown menu. Some Weka packages currently do not work (properly) with Java 9 or later (tigerJython and scatterPlot3D).

    How to Think Like a Computer Scientist looks like a good tutorial for Python 3.x newbies.
    Dr. Schwesinger has posted some additional Python textbooks for CSC223.
    We will be using the 3.x version of Python.
    Try running python -V to see that you are getting Python 3.x.x as your default.
        From the mcgonagall machine (ssh mcgonagall from acad) do the following actions in bold:
        Edit a file called .bash_profile in your login directory (create it if needed) and add these 2 lines near the top.
                export PATH="/usr/local/bin:${PATH}"
                alias python="/usr/local/bin/python3.7"
                alias ipython="/usr/local/bin/ipython3"
        Save the file and exit the editor, log out and log back into mcgonagall.
        Now type this:
                python -V    # You should see this:
                    Python 3.7.7
            If you install python on your own machine, just running python will get you the simpler-to-use interpreter.
            I will use ipython in lecture.

    The Python website is at
    There is a good on-line tutorial and reference by Steven F. Lott called Building Skills in Python. There is a PDF copy here.
    The IPython site is here.
We will be using Python for data preparation in assignment 1.
    We have Python installed on acad, but if you want your own copy:
    You can download Python 3.x from here. Use the most recent stable 3.x for this course.
    Documentation including tutorials for the 3.x library is here.

Here are my introductory slides on Python. We will explore Python in class.
    Using Notepad++: Go to Settings->Preferences...->Language (since version 7.1) or Settings->Preferences...->Tab Settings (previous versions)
    Check Replace by space    
    To convert existing tabs to spaces, press Edit->Blank Operations->TAB to Space.
    If you are a vim editor user, create a file called .vimrc in your login directory with the following lines:
        set ai
        set ts=4
        set sw=4
        set expandtab
        set sta
