Course Goals

• Learn visual and computation techniques and tools, for typical data types
• Learn how to complement each kind of methods
• Gain a breadth of knowledge
• Work on real datasets and problems
• Learn practical know-how (useful for jobs, research) through significant hands-on programming assignments

Announcements and Discussion

The fastest way to get help with homework assignments is to post your questions on Piazza. That way, only our TAs and instructor can help, your peers can too.

If you prefer that your question addresses to only our TAs and the instructor, you can use the private post feature (i.e., check the "Individual Students(s) / Instructors(s)" radio box).

While we welcome everyone to share their experiences in tackling issues and helping each other out, but please do not post your answers, as that may affect the learning experience of your fellow classmates.

For special cases such as failed submissions due to system errors, missing grades, failed file uploads, emergencies that prevent you from submitting, personal issues, you can contact the staff using a private Piazza post.

Course Staff & Office Hours

TAs will hold office hours starting week 2, except on Georgia Tech holidays (e.g., thanksgiving, MLK day, Recess break). Each office hour session will be run by at least one TA, and is 1 hour long. See GT’s academic calendar for the full list of holidays (https://registrar.gatech.edu/calendar). We will spread the office hours across weekdays.

Please note that you are always welcome to ask questions on Piazza. Office hours supplement Piazza, and do not replace it.

Course Schedule Evolving

This course can be very tough for many!

The amounts of time students spend on this class greatly vary, based on their backgrounds, and what they may already know. Some former students told us they spent about 40-60 hours on each homework assignment (we have 4 big assignments, and no exams), and some reported much less. For example, for the homework assignment about D3 visualization programming, students who are completely new to javascript, css, and html likely will spend significantly more time than their peers who have already tried them before. Some former students who do not have a computer science background found the homework assignments challenging, would take significant time and effort, but were rewarding, fun, and "do-able."

Students have at least 2 weeks to complete each homework assignment. Some students waited until the last week, and could not finish. It is critical to plan ahead and prepare for the significant time needed.

Some programming assignments involve high-level languages or scripting (e.g., Python, Java, SQL etc.). Some assignments involve web programming and D3 (e.g., Javascript, CSS, HTML). For example, an assignment on Hadoop and Spark may require you to learn some basic Java and Scala quickly, which should not be too challenging if you already know another high-level language like Python or C++. It is unlikely that you all know tools/skills needed in the programing tasks, so you are expected to learn many of them on the fly.

Basic linear algebra, probability and statistics knowledge is also expected.

Homework

We have 4 big assignments in total (subject to change). Visit this course's Canvas site for the assignment documents. See the schedule table above for deliverable due dates.

• [10%] HW1: Collecting & visualizing data, SQLite, D3 warmup, OpenRefine, Web Development with Flask and jQuery
• HW2: D3 Graphs and Visualization
• [15%] HW3: Hadoop, Spark, Pig and Azure
• [10%] HW4: Scalable PageRank via Virtual Memory (MMap), Random Forest, Scikit-Learn

Project

See project description. See the schedule table above for deliverable due dates.

Distance Learning Students (Q Section)

A standard 3-day lag applies to all homework and project deliverables.  For project presentation, a group that has DL student member can choose to:

1. Present in class without 3-day lag; or 
2. Submit a video presentation with 3-day lag (e.g., screen capture)

Grading Policy

1. There will be 4 homework assignments. Together, they are worth 50% (10%, 15%, 15%, 10%)  of the course grade.
2. There will be one course group project worth 50% of the course grade. The project components are:
1. Proposal (7.5% of course grade)
2. Proposal presentation (5%)
3. Progress report (5%)
4. Final poster presentation (7.5%)
5. Final report (25%)
3. You must achieve an overall weighted average of 60% to pass the course.
4. All deliverables will be graded by our TAs, except the project poster presentation, which will be peer-graded.
5. When assigning course grades, I will start with the standard grade thresholds (90, 80, etc.). I may lower (and never raise) the thresholds (i.e., to your benefits). For example, I may use 88 instead of 90.

Deliverable Due Dates

All homework and project deliverables will be due at the times shown in the Course Schedule. These times are subject to change so please check back often.

Plagiarism, Collaboration Policy, and Student Honor Code

• All course participants (myself, teaching assistants, and learners) are expected to know and abide by the Georgia Tech Academic Honor Code.
• Ethical behavior is extremely important in all facets of life.

• Plagiarism is a serious offense. You are responsible for completing your own work. You are not allowed to copy and paste, or paraphrase, or submit materials created or published by others, as if you created the materials. All materials submitted must be your own.
• You may discuss high-level ideas with other students at the "whiteboard" level (e.g., how cross validation works, use hashmap instead of array) and review any relevant materials online. However, each student must write up and submit his or her own answers.
• All incidents of suspected dishonesty, plagiarism, or violations of the Georgia Tech Honor Code will be subject to the institute’s Academic Integrity procedures (e.g., reported to and directly handled by the Office of Student Integrity (OSI)). Consequences can be severe, e.g., academic probation or dismissal, grade penalties, a 0 grade for assignments concerned, and prohibition from withdrawing from the class.

Late Policy and Due Dates

• All homework and project deliverables are due at the times shown in the Course Schedule. These times are subject to change so please check back often.
• Every homework assignment deliverable and every project deliverable comes with a 48-hour "grace period". You do not need to ask before using this grace period.
  
  Your deliverable may be submitted (and resubmitted) up to 48 hours after the official deadline without penalty, but Canvas will mark your submission as "late"
  
  Canvas automatically appends a "version number" to files that you re-submit. You do not need to worry about these version numbers, and there is no need to delete old submissions. We will only grade the most recent submission.
• Any deliverable submitted after the grace period will get 0 credit. We recommend that you submit your work before the grace period begins.
• We will not consider late submission of any missing parts of a deliverable. To make sure you have submitted everything, download your submitted files to double check. If your submitting large files, you are responsible for making sure they get uploaded to the system in time. You have 48 hours to verify your submissions!
• No penalties for medical reasons or emergencies. And should they arise, you must contact the Dean of Students office. Doctor's notes, medical documentation, explanation of emergencies, etc. should be submitted to the Dean’s office. After their office receives the information, we will notify me on your behalf.

Timing Policy

• The course videos follow a logical sequence that includes knowledge-building and experience-building (assignments).
• Assignments should be completed by their due dates, in order for timely peer assessment. Peer assessments should also be completed by their due dates, to give timely feedback.
• You will have access to the course content for the scheduled duration of the course.

Netiquette

• Netiquette refers to etiquette that is used when communicating on the Internet. Review the Core Rules of Netiquette. When you are communicating via email, discussion forums or synchronously (real-time), please use correct spelling, punctuation and grammar consistent with the academic environment and scholarship¹.
• We expect all participants (learners, faculty, teaching assistants, staff) to interact respectfully. Learners who do not adhere to this guideline may be removed from the course.
