ORIE Colloquium: Alexandre d'Aspremont (École Normale Supérieure) - Sparsity, Feature Selection and the Shapley Folkman Theorem.

This week's ORIE Colloquium speaker is Alexandre d'Aspremont of École Normale Supérieure. Professor d'Aspremont's talk "Sparsity, Feature Selection and the Shapley Folkman Theorem" will begin at 9:00 a.m. Tuesday, May 4.

https://events.cornell.edu/event/orie_colloquium_alexandre_daspremont_ecole_normale_superieure

The Shapley Folkman theorem acts as a central limit theorem for convexity: It shows that Minkowski sums of arbitrary bounded sets are increasingly close to their convex hull as the number of terms in the sum increases. This produces simple and explicit approximation bounds on a broad class of combin...

Dear ORIE ALUMNI and FRIENDS: ORIE will host a reception at the INFORMS Conference in Seattle Washington. We look forward to seeing you there: What: Cornell INFORMS Reception When: Monday, October 21 2019, 8:00 pm - 11:00 pm Where: Tom Douglas Palace Ballroom Address: 2100 5th Ave Seattle, WA 98121 Phone: (206) 734-3203
Congratulations to all of our ORIE graduates!
Mentor/Instructor for Technical Interview Refreshers at Cornell Tech NYC During the week of Dec 4-Dec 11, Cornell Tech will hold technical interview refresher workshops for its Master of Engineering students. We are looking for volunteer mentors/instructors. The workshops will be for technical students and the goals is to to refresh the application of some of the key CS concepts that are most commonly tested in technical interviews. The plan is to have 1or 2 session a day (each session will be 1-1.5 hrs) to have the students work through problems in small groups. The students will have a pre-read before these sessions to refresh on theory, but to make sure they are on track solving the problems, we need engineers who are proficient with concepts. If you are interested, please send me a personal message. Food and eternal gratitude from students will be plentiful! I would appreciate if you could let me know by the end of the day FRIDAY, 11/17 Topics in order of priority (ranked by students) [Complex data structures (linked list, graphs, trees, tries and their variations) and operations on those kinds of data structures: search, traversal, balancing trees.] [Sorting and search algorithms (Binary Search, Quick Sort, etc.)] [Backtracking and dynamic programming algorithms.] [ DFS and BFS problems.] [Greedy algorithms.] [Object Oriented programming.] [System design.]
