-To encourage presenting papers we cover earlier weeks of this course, we will give an additional bonus by scaling up your "presentation score" (up to 20%). That is, if you present in the second week (Lecture No 4), scaling factor 1.2 will be applied to your "presentation score", making your final score "presentation score" * 1.2. The scaling ratio decreases over time. For more details, please see this Presentation Schedule (to view this document, you must be logged in using an Illinois account).
