We propose a curriculum learning captioning method to caption fetal ultrasound images by training a model to dynamically transition between two different modalities (image and text) as training progresses. Specifically, we propose a course-focused dual curriculum method, where a course is training with a curriculum based on only one of the two modalities involved in image captioning. We compare two configurations of the course-focused dual curriculum; an image-first course-focused dual curriculum which prepares the early training batches primarily on the complexity of the image information before slowly introducing an order of batches for training based on the complexity of the text information, and a text-first course-focused dual curriculum which operates in reverse. The evaluation results show that dynamically transitioning between text and images over epochs of training improves results when compared to …
