Edge-based Discovery of Training Data for Machine Learning

Friday, February 8th, 2019 from 12-1 pm in GHC 6501.

Ziqiang Feng, CSD

Deep learning has become the gold standard of computer vision. The generation of high-quality labeled training data typically becomes the bottleneck of deep learning in areas such as natural science, ecology, and medical research, where domain expertise is required to correctly identify targets and thus crowdsourcing becomes non-viable. Yet it is in those areas deep learning has huge potential value. In the worst case, a single domain expert needs to sift through a large volume of unlabeled data to discover only a few positive examples.

In this talk, I will describe our ongoing work on Eureka, a system intended to improve the human expert's productivity in building a labeled training set. Eureka views a human's attention and time as the most precious resource throughout the system and helps to optimize the utilization of this critical resource. Eureka combines three techniques to achieve its goal: early discard, iterative discovery workflow, and edge computing. Experiments show that Eureka can reduce the amount of labeling effort by two orders of magnitude relative a brute force approach.

Based on joint work with Shilpa George, Jan Harkes, Padmanabhan Pillai, Roberta Klatzky, and Mahadev Satyanarayanan.

General Info

The Student Seminar Series is an informal research seminar by and for SCS graduate students from noon to 1 pm on Mondays and Fridays. Lunch is provided by the Computer Science Department (personal thanks to Debbie Cavlovich!). At each meeting, a different student speaker will give an informal, 40-minute talk about his/her research, followed by questions/suggestions/brainstorming. We try to attract people with a diverse set of interests, and encourage speakers to present at a very general, accessible level.

So why are we doing this and why take part? In the best case scenario, this will lead to some interesting cross-disciplinary work among people in different fields and people may get some new ideas about their research. In the worst case scenario, a few people will practice their public speaking and the rest get together for a free lunch.


Guideline & Speaking Requirement Need-to-Know

Note: Step #1 below are applicable to all SSS speakers. You can schedule AT MOST THREE talks per semester.

SSS is an ideal forum for SCS students to give presentations that count toward fulfilling their speaking requirements. The specifics, though, vary with each department. For instance, students in CSD will need to be familiar with the notes in Section 8 of the Ph.D. document and follow the instructions outlined on the Speakers Club homepage. Roughly speaking, these are the steps:

  1. Schedule a talk with SSS by sending your name, department name, your talk title, talk abstract (including additional info like "Joint work with..." or "In Partial Fulfillment of the Speaking Requirement"), and a link to your home page to sss@cs at least TWO WEEKS before your scheduled talk.
  2. After you are confirmed with your SSS slot, go to the Speakers Club Calendar and schedule your talk at least THREE WEEKS in advance of the talk date.
  3. On the day of your talk, make sure you print Speakers Club evaluation forms for your evaluators to use.
Students outside of CSD will need to check with their respective departments regarding the procedure. As another example, ISRI students fulfill their speaking requirements by attending a semesterly Software Research Seminar and giving X number of presentations per school year. If you have experience with your department that might help others in your department, please feel free to contribute your knowledge by emailing us. Thank you!
