Multi-Task Learning for Ambiguous Candidate Identification with Pre-trained Model

Daesik Jang, Hyewon Choi


Abstract
Recently, research using multimodal datasets containing image and text information has been conducted actively. One of them is the SIMMC2.1 dataset. It is a more complicated dataset than answering a conversation using only text because it should predict an answer after understanding the relationship between images and text. Therefore, there are limitations to answering a conversation only using text-based models such as BERT or GPT-2, so models with both image and language understanding abilities should be considered. We propose a new model that is effective for the ambiguous candidate identification task in DSTC11 SIMMC2.1 Tark. It consists of a simple pipeline model structure, which has two steps. The first step is to check whether there is ambiguity in the current user utterance, and the second step is to extract objects mentioned in the ambiguous utterance of the user. We suggest a new learning framework with a pre-trained image model and text model that is effective for the ambiguous candidate identification task. Experiments show that the proposed method can improve the model performance, and our model achieved 3rd place in sub-task 1 of the SIMMC2.1 track.
