Timeframe: It will open Thursday 4/14, 12:01 AM, and close Saturday 4/16, 11:59 PM.
The exam will close at 11:59 pm regardless of when you started.
The exam will be take-home. It is openbook, open note, open internet, but closed to people.
This means you cannot communicate with anyone about the exam, including asking someone through the Internet (like stackoverflow) for help and receiving help.
Like prior mini-exams, it consists of 2 parts that each have a time limit of 2 hours. Both parts will have data sets and they will be different.
Grading policy specifics
Your answer will not be judged on the accuracy of the model, only on how you contextualize it to a simple probabilistic baseline (e.g. if there are 4 categories and they are all equally likely, you compare it to an accuracy baseline of 25%. However, if one category is present 50% of the time, your baseline accuracy would be 50% because the baseline model could just always guess the most popular category).
Warning: To provide more fine-grained granularity of measuring mastery, questions are split into smaller parts. This means the number of points per question part is not uniform.
All other information is similar to Mini-Exam 1’s. Such as getting the files, Gradescope, Sakai, asking for help, grading policy, etc.
Mini-Exam 3 Retake Logistics
Timeframe: It will open Thursday 4/14, 12:01 AM, and close Saturday 4/16, 11:59 PM.
The exam will close at 11:59 pm regardless of when you started.
You may use things that you have learned that were not in the modules that this exam is testing but you can answer it without knowing any modules beyond what this exam is testing.
The data sets and events will be different.
You do not need to do both parts. You can only do one part if you wish. You must do ALL of the questions in that part though. We will take the max score per part.
