How Can I Improve? Using GPT to Highlight the Desired and Undesired Parts of Open-ended Responses

no code implementations1 May 2024 Jionghao Lin, Eason Chen, Zeifei Han, Ashish Gurung, Danielle R. Thomas, Wei Tan, Ngoc Dang Nguyen, Kenneth R. Koedinger

To quantify the quality of highlighted praise components identified by GPT models, we introduced a Modified Intersection over Union (M-IoU) score.

Harnessing the Power of Beta Scoring in Deep Active Learning for Multi-Label Text Classification

no code implementations15 Jan 2024 Wei Tan, Ngoc Dang Nguyen, Lan Du, Wray Buntine

Within the scope of natural language processing, the domain of multi-label text classification is uniquely challenging due to its expansive and uneven label distribution.

Re-weighting Tokens: A Simple and Effective Active Learning Strategy for Named Entity Recognition

no code implementations2 Nov 2023 Haocheng Luo, Wei Tan, Ngoc Dang Nguyen, Lan Du

Active learning, a widely adopted technique for enhancing machine learning models in text and image classification tasks with limited annotation resources, has received relatively little attention in the domain of Named Entity Recognition (NER).

Low-Resource Named Entity Recognition: Can One-vs-All AUC Maximization Help?

no code implementations2 Nov 2023 Ngoc Dang Nguyen, Wei Tan, Lan Du, Wray Buntine, Richard Beare, Changyou Chen

Named entity recognition (NER), a task that identifies and categorizes named entities such as persons or organizations from text, is traditionally framed as a multi-class classification problem.

Robust Educational Dialogue Act Classifiers with Low-Resource and Imbalanced Datasets

no code implementations15 Apr 2023 Jionghao Lin, Wei Tan, Ngoc Dang Nguyen, David Lang, Lan Du, Wray Buntine, Richard Beare, Guanliang Chen, Dragan Gasevic

We note that many prior studies on classifying educational DAs employ cross entropy (CE) loss to optimize DA classifiers on low-resource data with imbalanced DA distribution.
