An End-to-End Class-Aware and Attention-Guided Model for Object State Classification

Filippos Gouidis, Konstantinos Papoutsakis, Theodore Patkos, Antonis Argyros et autres

Object State Classification (OSC) is a critical task in computer vision, enabling systems to understand the functional state of objects. This work proposes a novel end-to-end architecture for OSC that leverages the inherent relationship between object classification and state recognition. Our approach …

Recognizing Unseen States of Unknown Objects by Leveraging Knowledge Graphs

Filippos Gouidis, Konstantinos Papoutsakis, Theodore Patkos, Antonis Argyros et autres

We investigate the problem of Object State Classification (OSC) in the context of zero-shot learning. Specifically, we propose the first method for Zero-shot Object-agnostic State Classification (OaSC) that, given an image, infers the state of a single object without relying on the …

LLM-aided Knowledge Graph construction for Zero-Shot Visual Object State Classification

Filippos Gouidis, Katerina Papantoniou, Konstantinos Papoutsakis, Theodore Patkos et autres

The problem of classifying the states of objects using visual information holds great importance in both applied and theoretical contexts. This work focuses on the special case of Zero-shot Object-Agnostic State Classification (ZS-OaSC). To tackle this problem, we introduce an innovative strategy …

Visual Gorgias: A Mechanism for the Visualization of an Argumentation Dialogue

Alexandros Vassiliades, Ilias Papadimitriou, Nick Bassiliades, Theodore Patkos

The area of eXplainable Artificial Intelligence (XAI) has been given great attention during the last decade, due to the obscurity that exists on how a data-driven model makes a decision. One idea in order to make Artificial Intelligence (AI) systems more explainable …
