| Challenge: | Active learning has been proposed to alleviate data acquisition challenges for rare-class tasks when the class label is very infrequent (e.g., 5% of samples). |
| Approach: | They propose to use transformers to train models on closely related tasks and evaluate acquisition strategies, including a proposed probability-of-rare-class approach to dissonance detection. |
| Outcome: | The proposed method improves model accuracy while iterative transfer-learning does not improve cold-start performance. |

| Challenge: | Anxiety disorders are the most common of mental illnesses, but little is known about how to detect them from language. |
| Approach: | They propose to use discourse-level information in addition to lexical-level large language model embeddings to evaluate the utility of a lexico-discourse model. |
| Outcome: | The proposed model outperforms models based on state-of-the-art contextual embeddings and uses discourse patterns of causal explanations significantly more than models derived from Sentence-BERT and DiscRE, and is comparable to psychological models. |

| Challenge: | This tutorial will cover the latest techniques and libraries for doing so at each level of analysis. |
| Approach: | This tutorial will cover the latest techniques and libraries for doing so at each level of analysis. |
| Outcome: | The tutorial covers human-centered techniques that provide benefit to traditional document- or word-level NLP tasks. |
