From Text to Parameters: Predicting Item Parameters from Embedding Regularization with Reliability and Design Ceilings
从文本到参数:用嵌入正则化预测项目参数及其信度与设计上限
Newly developed items must ordinarily be field tested before their psychometric properties are known, creating a cold start problem for item calibration. Predicting item parameters from features is a long standing measurement problem dating back to the Linear Logistic Test Model; modern text embeddings now automate the design matrices traditionally specified by hand. We propose an evaluation framework combining regularized regression on item text embeddings, repeated cross…
