Sensory Modalities01:15

Sensory Modalities

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
Retrieval01:12

Retrieval

Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...
Nonconscious Mimicry01:13

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.
Visual Agnosia01:12

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
The Representativeness Heuristic02:13

The Representativeness Heuristic

The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Area of Science:

  • Computer Science
  • Artificial Intelligence
  • Information Retrieval

Background:

  • Cross-modal retrieval, particularly for image-text pairs, is crucial for diverse applications but faces challenges.
  • Modality heterogeneity, missing data, and noise hinder traditional and deep learning methods.
  • Existing deep learning approaches struggle with long-range semantic relationships and incomplete data.

Purpose of the Study:

  • To develop a robust graph-based method for incomplete modality awareness cross-modal retrieval (GCMR-IMA).
  • To address limitations in handling missing modalities and capturing long-range semantic dependencies.
  • To enhance the effectiveness and robustness of cross-modal retrieval systems.

Main Methods:

  • Proposed a dual-layer semantic architecture with image-text dual embedding for global semantic graph learning.
  • Introduced a sparsified modality adjacency graph to model inter-modality relationships and enhance awareness.
  • Implemented a graph-guided missing modality awareness method and an adaptive loss function for context-aware detection.

Main Results:

  • GCMR-IMA demonstrates strong performance despite the presence of missing modalities.
  • The method effectively captures long-range semantic relationships and handles modality heterogeneity.
  • Experimental results validate the robustness and effectiveness of the proposed framework.

Conclusions:

  • The GCMR-IMA framework significantly improves cross-modal retrieval, especially in scenarios with incomplete data.
  • This approach offers enhanced robustness and effectiveness for real-world applications.
  • The study contributes a novel solution for advanced image-text retrieval systems.
