Associative Learning01:27

Associative Learning

963
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Vision01:24

Vision

58.9K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Visual System01:26

Visual System

1.5K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Visual Agnosia01:12

Visual Agnosia

707
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...

Observational Learning01:12

Observational Learning

701
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Cognitive Learning01:21

Cognitive Learning

896
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

    Area of Science:

    • Artificial Intelligence
    • Computer Vision
    • Natural Language Processing

    Background:

    • Deep learning has accelerated visual question answering (VQA), which requires understanding images and questions.
    • Current VQA models heavily depend on dataset-specific knowledge, limiting their ability to answer questions requiring external information.
    • Some questions necessitate specialized knowledge beyond typical dataset information for accurate responses.

    Purpose of the Study:

    • To propose a novel framework, the knowledge-based augmentation network (KAN), to address limitations in existing VQA systems.
    • To enhance VQA by integrating object-related open-domain knowledge, including common sense and experiential reasoning.
    • To develop an adaptive attention mechanism for dynamically balancing external knowledge with visual information.

    Main Methods:

    • Extracting enhanced visual information from images.
    • Utilizing a knowledge graph to provide external common sense and reasoning capabilities.
    • Designing an attention module to adaptively weigh external knowledge against detected objects based on specific questions.

    Main Results:

    • The proposed KAN achieved state-of-the-art performance on three challenging VQA datasets: VQA v2, VQA-CP v2, and FVQA.
    • The integration of open-domain knowledge proved beneficial for baseline VQA models.
    • The adaptive attention mechanism effectively balanced external knowledge and visual object information.

    Conclusions:

    • The knowledge-based augmentation network (KAN) significantly improves visual question answering capabilities by incorporating external knowledge.
    • The framework demonstrates the effectiveness of open-domain knowledge and adaptive attention in VQA.
    • KAN offers a promising direction for developing more robust and knowledgeable VQA systems.
