Shunit Agmon is a PhD candidate in the Computer Science Department at the Technion – Israel Institute of Technology, under the supervision of Dr. Kira Radinsky and Prof. Benny Kimelfeld. Her research focuses on mitigating the effects of social biases on machine learning algorithms.

During her doctorate studies she also worked as a research intern at Amazon. Prior to that, she had completed her BSc (summa cum laude) and her MSc at the Technion as well. Shunit is a two-time recipient of the student research prize for cross-discipline collaboration in Data Science, funded by the Israeli planning and budgeting committee.

Statement of Purpose

In recent years, natural language processing (NLP) models are increasingly being used in clinical prediction tasks. These models are usually trained on a corpus of text describing clinical trials. For decades, clinical trials have excluded woman participants. NLP models, and specifically word embeddings, have been shown to capture and aggravate biases from the texts they are trained on. Therefore, models trained on the corpus of clinical trials will be inherently biased, and lead to poorer performance on women than on men.

Existing efforts to mitigate gender bias in word embeddings focus on removing the gender information from the embeddings. In the clinical domain, this approach is unhelpful: gender is an important feature that should be used in predictive models. We propose a gender-sensitive approach to mitigate the bias in word embeddings for healthcare, where the contribution of each clinical trial to the training process of the embeddings is determined by the number of female participants in that trial. We compare the performance of the gender-sensitive embeddings to a neutral baseline and show that the performance increases for several clinical prediction tasks: comorbidity classification, ICU readmission prediction, and hospital length of stay.
 

Target Audience

The target audience for this activity is professionals and students interested in health informatics.

Learning Objectives

After participating in this webinar the listener should be better able to:

  • Identify the effects of biases in the data on natural language processing model results.
  • Apply a data augmentation method to train gender-sensitive word embeddings
     

Format

  • 35-minute presentation by article author(s) considering salient features of the published study and its potential impact on practice
  • 25-minute discussion of questions submitted by listeners via the webinar tools and moderated by JAMIA Student Editorial Board members.
