Researchers have developed LiFT, a novel framework designed to enhance the in-context learning (ICL) capabilities of large language models (LLMs) for longitudinal NLP tasks. These tasks, which involve analyzing temporally ordered text for applications like mental health monitoring or tracking stance evolution, often suffer from data scarcity. LiFT is a model-agnostic approach that unifies diverse longitudinal tasks through a shared instruction schema, incorporating sequential dependencies, curriculum learning, and temporal conditioning. Evaluations on five longitudinal datasets show that LiFT significantly outperforms standard instruction fine-tuning (IFT) models under identical ICL conditions, particularly benefiting minority classes and demonstrating transferable longitudinal modeling skills.
