KICNLE

This repository contains the official PyTorch implementation of paper "Knowledge-Augmented Visual Question Answering with Natural Language Explanation" for Transaction on Image Processing (TIP) 2024.

Overview

The KICNLE model enhances visual question answering by using an iterative method where each answer is refined based on the previous explanation. It includes a knowledge retrieval module to ensure relevant and accurate information. This results in high-quality, consistent answers and explanations closely tied to the visual content.
