- [Jan 27] Class Test 1 will be on Feb 3rd week. Syllabus will include whatever is covered upto Feb 1st week. Please register in the CSE Moodle. Enrollment key is shared on Teams
- [Jan 27] Project Choice submission deadline: Jan 28th 11:59 PM IST .
- Note: for students, who are not able to register, kindly wait till 7th when the window closes. I will not be able to answer your emails individually. I will first approve based on CGPA and other criteria (such as total class strength cap etc.), once the window closes.
- Every registered student should join the Google mailing list firstname.lastname@example.org. All urgent announcements would be made through the group. This group is meant only for registered (and approved) students. Kindly mention your roll number and the fact that you have registered in ERP.
- IR 2011-22 Spring will be a fully online research-oriented course.
- First class on January 10 (Monday), at 8:00 am (deferred from 4th due to ERP registration issues). Join the class Information-Retrieval-2022Spring on MS Teams (IITKGP domain; Code: g7tgjqc).
- The course requires an understanding of the foundation of algorithms and data structures, probability and statistics, and knowledge of the basics of Natural Language Processing, and Machine Learning. This will be a research-oriented course that would require students to understand several CS research papers. There will be a term project that needs to be done using Python/Java. It is advisable to take this course only if you have the necessary background.
