Questions: We will use CampusWire for class questions/discussion. The link to join our class on CampusWire is in Brightspace. Instead of sending email to the TA list, please post your questions on CampusWire.
This course provides an introduction to foundational areas of artificial intelligence and current techniques for building intelligent systems. Topics will include: problem solving, state-space representation, heuristic search techniques, game playing, knowledge representation, logical reasoning, reasoning under uncertainty, decision making, machine learning, and planning.
Prerequisites: CS25100 Data Structures (grade of C or better)
S. Russell and P. Norvig (2010). Artificial Intelligence: A Modern Approach. Prentice Hall, 3rd Edition.
There will be four homework/programming assignments that will be posted on the schedule. Assignments should be submitted online in gradescope or via turnin on data.cs.purdue.edu. Details will be provided in the assignments. Programming projects should be written in Python, unless otherwise noted. In general, questions about the details of homeworks/projects should be directed to the TA on CampusWire.
There will be one essay on the opportunities and challenges that Artificial Intelligence will bring to our society. Details will be discussed in the class. The essay should be submitted via gradescope in PDF format.
There will be several quizzes in class, as well as an evening midterm and a comprehensive final exam. Exams will be closed book and closed notes. We will use HotSeat for the quizzes. Each quizz will be made available on HotSeat for 24 hours to accomondate excusable reasons not to show up in classes.
Assignments are to be submitted by the due date listed. Each person will be allowed three days of extensions which can be applied to any combination of assignments (homework/projects/essays only) during the semester without penalty. After that a late penalty of 15% per day will be assigned. Use of a partial day will be counted as a full day. Use of extension days must be stated explicitly at the time of the late submission (by accompanying email to the TA), otherwise late penalties will apply. Extensions cannot be used after the final day of classes (ie., April 30). Extension days cannot be rearranged after they are applied to a submission. Use them wisely!
Assignments will NOT BE accepted if they are more than five days late. Additional extensions will be granted only due to serious and documented medical or family emergencies.
Students are expected to attend all classes unless they are ill or otherwise unable to attend class. We provide both in-class and online ways to attend the class. The Zoom information to attend the class online are listed in Brightspace. Either way students are expected to complete in-class quizzes in a timely manner via HotSeat. If students feel ill, have any symptoms associated with COVID-19, or suspect they have been exposed to the virus, students should stay home and contact the Protect Purdue Health Center (496-INFO).
Students need to inform the instructor of any conflict that can be anticipated and will affect the timely submission of an assignment or the ability to take an exam due to COVID.
Classroom engagement is extremely important and associated with your overall success in the course. The importance and value of course engagement and ways in which you can engage with the course content even if you are in quarantine or isolation, will be discussed at the beginning of the semester. Student survey data from Fall 2020 emphasized students’ views of in-person course opportunities as critical to their learning, engagement with faculty/TAs, and ability to interact with peers.
Only the instructor can excuse a student from a course requirement or responsibility. When conflicts can be anticipated, such as for many University-sponsored activities and religious observations, the student should inform the instructor of the situation as far in advance as possible. For unanticipated or emergency conflicts, when advance notification to an instructor is not possible, the student should contact the instructor/instructional team as soon as possible by email, through Brightspace, or by phone. In cases of bereavement, quarantine, or isolation, the student or the student’s representative should contact the Office of the Dean of Students via email or phone at 765-494-1747. Our course Brightspace includes a link to the Dean of Students under ‘Campus Resources.’
If you must quarantine or isolate at any point in time during the semester, please reach out to all TAs and me via email so that we can communicate about how you can continue to learn remotely. Work with the Protect Purdue Health Center (PPHC) to get documentation and support, including access to an Academic Case Manager who can provide you with general guidelines/resources around communicating with your instructors, be available for academic support, and offer suggestions for how to be successful when learning remotely. Your Academic Case Manager can be reached at firstname.lastname@example.org. Importantly, if you find yourself too sick to progress in the course, notify your academic case manager and notify me via email or Brightspace. We will make arrangements based on your particular situation.
We provide a Zoom link to attend the class remotely in case of quarantine/isolation. The link can be accessed via Brightspace. The attendance is usually taken via Hotseat, which can be accessed remotely as well.
The Protect Purdue Plan, which includes the Protect Purdue Pledge, is campus policy and as such all members of the Purdue community must comply with the required health and safety guidelines. Required behaviors in this class include: staying home and contacting the Protect Purdue Health Center (496-INFO) if you feel ill or know you have been exposed to the virus, properly wearing a mask in classrooms and campus building, at all times (e.g., mask covers nose and mouth, no eating/drinking in the classroom), disinfecting desk/workspace before and after use, maintaining appropriate social distancing with peers and instructors (including when entering/exiting classrooms), refraining from moving furniture, avoiding shared use of personal items, maintaining robust hygiene (e.g., handwashing, disposal of tissues) prior to, during and after class, and following all safety directions from the instructor.
Students who are not engaging in these behaviors (e.g., wearing a mask) will be offered the opportunity to comply. If non-compliance continues, possible results include instructors asking the student to leave class and instructors dismissing the whole class. Students who do not comply with the required health behaviors are violating the University Code of Conduct and will be reported to the Dean of Students Office with sanctions ranging from educational requirements to dismissal from the university.
Any student who has substantial reason to believe that another person in a campus room (e.g., classroom) is threatening the safety of others by not complying (e.g., not properly wearing a mask) may leave the room without consequence. The student is encouraged to report the behavior to and discuss the next steps with their instructor. Students also have the option of reporting the behavior to the Office of the Student Rights and Responsibilities. See also Purdue University Bill of Student Rights.
