Abstract:

We present a novel method for Audio-Visual Question Answering (AVQA) in real-world scenarios where one modality (audio or visual) can be missing. Inspired by human cognitive processes, we introduce a Trans-Modal Associative (TMA) memory that recalls missing modal information (i.e., pseudo modal feature) by establishing associations between available modal features and textual cues. During training phase, we employ a Trans-Modal Recalling (TMR) loss to guide the TMA memory in generating the pseudo modal feature that closely matches the real modal feature. This allows our method to robustly answer the question, even when one modality is missing during inference. We believe that our approach, which effectively copes with missing modalities, can be broadly applied to a variety of multimodal applications.

1. INTRODUCTION

In our daily lives, we often rely on both visual and auditory cues for answering questions [1]–[8]. To simulate this human perception capability in question-answering, the AudioVisual Question Answering (AVQA) task has emerged. This task guides machines to comprehend and respond to questions by utilizing combined audio-visual information relevant to the question text. Due to this property, the AVQA task is closely linked to various practical real-world applications, including autonomous navigation [9] and interactive education [10].
