In the lab meeting this week, 24th of Sep, we will discuss paper ideas/plans that lab members have or what they are currently working on for the upcoming TACL or *ACL conference deadlines. The meeting will be at TASC1 9408 from 1030 hours.
In the lab meeting on Wednesday, 17th September in TASC1 9408 at 1030 hours, Golnar will give a talk about Detecting Health Related Discussions in Everyday Telephone Conversations for Studying Medical Events in the Lives of Older Adults. Following is the abstract of the paper:
We apply semi-supervised topic modeling techniques to detect health-related discus- sions in everyday telephone conversations, which has applications in large-scale epidemiological studies and for clinical interventions for older adults. The privacy requirements associated with utilizing everyday telephone conversations preclude manual annotations; hence, we explore semi-supervised methods in this task. We adopt a semi-supervised version of Latent Dirichlet Allocation (LDA) to guide the learning process. Within this framework, we investigate a strategy to discard irrelevant words in the topic distribution and demonstrate that this strategy improves the average F-score on the in-domain task and an out-of-domain task (Fisher corpus). Our results show that the increase in discussion of health related conversations is statistically associated with actual medical events obtained through weekly self-reports.
In the lab meeting this week, 10th of Sep, we will discuss upcoming conference deadlines and how to submit papers to them. The meeting will be at TASC1 9408 from 1030 hours.
In the lab meeting this week, Aug 27, we will continue the tutorial about Bayesian Inference. The meeting will be at TASC1 9408 from 1100 hours.
The topic of the lab meeting this week, Aug 20, is the Bayesian Inference. We are going to read following tutorial.
