Deep Learning for Vision

NUS SoC, 2017/2018, Semester I
CS 6101 - Exploration of Computer Science Research

Last updated: September 7, 2017 - Updated venue and assignments.
July 5, 2017 - Initial port of last year's home page.

This is a section of the CS 6101 Exploration of Computer Science Research at NUS. CS 6101 is a 4 modular credit pass/fail module for new incoming graduate programme students to obtain background in an area with an instructor's support. It is designed as a "lab rotation" to familiarize students with the methods and ways of research in a particular research area. The lab rotation is hosted by the Web IR / NLP Group (WING) at NUS, led by Min-Yen Kan.

Our section will be conducted as a group seminar, with class participants nominating themselves and presenting the materials and leading the discussion. It is not a lecture-oriented course and not as in-depth as Fei-Fei Li et al.'s original course at Stanford, and hence is not a replacement, but rather a class to spur local interest in Deep Learning for Vision. Unlike the original course, we do not require you to do projects, assignments or homework, although those that attempt this will be encouraged to present in the project showcase at the end of the course to the general public.

This "course" is offered twice, for Session I (Weeks 3-7)and Session II (Weeks 8-13), although it is clear that the course is logically a single course that builds on the first half. Nevertheless, the material should be introductory and should be understandable given some prior study.

A discussion group will be on Slack . Students and guests, please login when you are free. If you have a,,,, or email address you can create your Slack account for the group discussion without needing an invite.

Meeting Venue and Time

18:00-20:00, Tuesdays for both Sessions I (Weeks 3-7) and Session II (Weeks 8-13).

Updated Venue is Active Learning Lab (COM1 #B1-03).

For directions to NUS School of Computing (SoC) and COM1: please read the directions here, to park in CP15 or take the shuttle bus to SoC.

Please eat before the course or during (we don't mind -- like a brown-bag seminar series).


Welcome. If you are an external visitor and would like to join us, please email Kan Min-Yen to be added to the class role. Guests from industry, schools and other far-reaching places in SG welcome, pending space and time logistic limitations. The more, the merrier.

External guests will be listed here in due course once the course has started. Please refer to our Slack after you have been invited for the most up-to-date information.

We're happy to report that the Stanford course CS231n: Convolutional Neural Networks for Visual Recognition, taught by Fei-Fei Li, Justin Johnson and Serena Yeung has agreed to let us run an iteration of their course at NUS. Please refer to their page for the detailed syllabus.

Please note that the original course contains additional lectures that are prerequisites to the materials that we are using. Our course starts on Lecture 4, but participants may want to start with the pre-flight Lectures 1-3 that we may cover optionally before the course formally starts. Please check in Slack for more details.
