In recent years, Visual Question Answering (VQA) has gained significant
attention for its diverse applications, including intelligent car assistance,
aiding visually impaired individuals, and document image information retrieval
using natural language queries. VQA requires effective integration of
information from questions and images to generate accurate answers. Neural
models for VQA have made remarkable progress on large-scale datasets, with a
primary focus on resource-rich languages like English. To address this, we
introduce the ViCLEVR dataset, a pioneering collection for evaluating various
visual reasoning capabilities in Vietnamese while mitigating biases. The
dataset comprises over 26,000 images and 30,000 question-answer pairs (QAs),
each question annotated to specify the type of reasoning involved. Leveraging
this dataset, we conduct a comprehensive analysis of contemporary visual
reasoning systems, offering valuable insights into their strengths and
limitations. Furthermore, we present PhoVIT, a comprehensive multimodal fusion
that identifies objects in images based on questions. The architecture
effectively employs transformers to enable simultaneous reasoning over textual
and visual data, merging both modalities at an early model stage. The
experimental findings demonstrate that our proposed model achieves
state-of-the-art performance across four evaluation metrics. The accompanying
code and dataset have been made publicly accessible at

advancements within the research community, fostering the development of more
multimodal fusion algorithms, specifically tailored to address the nuances of
low-resource languages, exemplified by Vietnamese.
