Seeing Me in My Office:
Please feel free to stop by my office anytime. My office is in MCS 286 (111 Cummington Mall). I am generally around every day. I may be in meetings, so the best time to reach me is during office hours. If you have classes during my office hours, speak to me after our lecture to make an appointment that works for both of us. I'm happy to talk with you about the course, research in AI, computer vision, machine learning, and pattern recognition, your plans for the future, or anything else. Check out my personal web page (in need of updating...) to get to know me a little.
Responsibilities of the Teaching Fellows:
Yi and Wenda are responsible for teaching the six laboratory sections and helping you out during their office hours. They will also help me design the written homework and programming projects, and they will manage the graders. Please contact the TFs first if you have questions about your homework grades.
Our goal is to learn about computer systems that exhibit intelligent behavior, in particular, perceptual and robotic systems. Topics include human computer interfaces, computer vision, robotics, machine learning, game playing, knowledge representation, planning, pattern recognition, and natural language processing.
Prerequisites of CS440: Geometric Algorithms (CAS CS 132) or Linear Algebra (CAS MA 242), 1 Year Programming Experience (CS 112 level, Python, Java, or C++) or consent of instructor. Prerequisites of CS640: Same as above and BA background in Computer Science (e.g., Algorithms, Theory, Programming Languages).
Handouts: The updated course syllabus and most handouts are made available online. Check our course web page at least once a week for homework assignments and other information.
Textbook: You are not required to buy a text book. I will direct you to additional materials on the web (e.g., Wikipedia). For background reading, you may go to the Science Library on Cummington St. I requested that two books are placed on reserve for you there: Artificial Intelligence by Patrick H. Winston (barnesandnoble and amazon) and Artificial Intelligence A Modern Approach by Russell and Nordiv, Edition 2 or Edition 3. Both books provide a fundamental background of AI. I will follow, for example, the chapters about Expert Systems and Neural Nets in the Winston book and about Robotics in the Russell and Norvig book, and then augment the materials with newer articles, especially with regards to deep learning.
Computing Environment: You will use the Computer Science Department's main server csa2.bu.edu to submit programming solutions. To get an account on csa2, go to the Computer Science Department's Undergraduate Lab located at 730 Commonwealth Ave. You can work on various platforms in the lab there (and have immediate access to the computing staff and TF help). You can also access csa2 remotely using scp and ssh (linux) or putty and WinSCP (Windows).
Class Participation: Come to class and participate regularly. Reading the assigned texts and listening in class will only give you a "passive understanding" of the material. I encourage discussions in class to help you acquire an "active understanding" of the material so that you can evaluate existing computer systems critically and learn to develop your own creative solutions.
Reading: To prepare for each class, you will be asked to read textbook sections, wikipedia pages and journal papers, and explore web sites. You can achieve a good understanding and appreciation of the state-of-the-art in artificial intelligence if you read the assigned texts thoroughly.
Homework: The homework includes three programming
assignments and three written problem sets. The due dates are listed below.
Programs and reports on your program performance must be submitted
electronically. Guidelines for submission are provided with each assignment.
We allow teams of two students for the programming assignments. Each student
must prepare their own written homework and hand it in at the beginning of
class. To speed up the grading process of the written homework, each exercise
will be graded separately. Therefore (and for stricter privacy rules), you will
have to prepare a cover sheet for each of your exercise solutions and then hand
in separately-stapled solutions for each exercise. The cover sheet should be
empty except for your name, BU ID, and statements whether you are in CS 440 or
640 and which lab section you are assigned to.
Late solutions will be levied a late penalty of 20% per day (up to three days). After three days, no credit will be given.
"Should Robots be our Friends?" Symposium: This year we have an opportunity to participate in the international BU Symposium on ethical and social scientific implications of the growing emotional engagement of humans with AI agents and robots. which will discuss the promises and perils of AI technology. The symposium is on Thursday, April 11. You are invited to attend the full symposium (register online) or attend just a single one-hour panel. For those students who cannot make it at all, we plan to make a video available. There will be a AI homework question with regards to the material discussed in the symposium. You will have an opportunity to submit a 250-word abstract (deadline TBA) and a 2,500-word paper (deadline TBA) if you are interested to participate in a poster session. Such participation is not required for CS440/640 but is helpful for anybody who would like to do research in AI.
CS 640 Project: This year, 45 students are enrolled in CS 640. A project is only required for students enrolled in CS 640. The project involves developing a computer vision system. More details will be announced shortly. We will discuss your project's scope, design, and presentation with you in class, labs, and office hours. The project will be due in early April.
Colloquia: Students enrolled in CS440 and CS 640 are encouraged
to attend the CS Department Seminars.
Try to make a couple of talks by faculty candidates. Such talks are
extremely well prepared and approachable. They will be announced only by email to
email@example.com and held typically on M/W/F at 11 am in March and April.
CS 640 students must also attend a session at the workshop:
CS 640 students must attend two of the three BU AIR Distinguished Speakers Seminars held in 610 Com Ave on Mondays, 11-12, and write a report.
Talk date & title:
CS 640 students must also attend a session at the workshop:
CS 640: Talk Reports: Students enrolled in CS 640 must attend at least three talks on subjects related to Artificial Intelligence and write a summary on each talk. Two of these talks must be from the list above. The one-page review should give a problem definition, summarize the algorithms and results, discuss the work critically, and also briefly explain how the work relates to material discussed in class. You must submit at the beginning of class on the dates listed in the syllabus. Check your text for typographical and grammatical errors. You will lose points if you simply copy the speaker's abstract, your review is late, contains typographical and grammatical errors, does not contain a discussion, and does not contain a statement how the talk relates to class material.
Exams: There will be two exams on the material discussed in the class and practiced with homeworks. The exams will be quite easy for students who come to class, participate in our discussions, and keep up with homework assignments and programming projects. The date of the midterm exam is Thursday, 2/28, 2019, the date of the final exam is May 9, 2019. The final exam will focus on material discussed in the second part of the course, but may test earlier material. You are allowed to use one double-sided page of notes in each exam.
Grading Policy: Your final grade will be determined as follows:
|Programming Assignments (CS440: P1-3, CS640: P1, P3)||25%||10%|
|Written Problem Sets||20%||15%|
|Class participation (Lecture and Lab)||5%||5%|
|Project and presentation||0%||15%|
You are encouraged to collaborate on the solution of the homework. If you do, you must acknowledge your collaborators. Each student must submit his or her own electronic version of the solutions. If you use algorithms or code that are not your own original work and that were not provided in class or discussed in the reading materials, you must give a detailed acknowledgment of your source.
Cheating and plagiarism are not worthy of Boston University students. I expect you to abide by the rule stated above and the standards of academic honesty and computer ethics policy described in http://www.bu.edu/computing/ethics/ and http://www.bu.edu/academics/policies/academic-conduct-code.
Artificial Intelligence is an elective course that will introduce you to an exciting topic in computer science. It should be fun and not too much of a struggle for you. Make sure that you have had the prerequisites. Depending on your level of programming experience and/or mathematics background, the course may be challenging for you. If you do not understand the material, ask for help immediately. Ask questions in class. If one student is confused about something, then maybe others are also confused and grateful that someone asked. Please come and see me or the TFs for help or send us email. Our task is to help you learn a very interesting topic.
