Sign Test for Matched Pairs01:17

Sign Test for Matched Pairs

87
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

Associative Learning01:27

Associative Learning

276
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...

Visual Agnosia01:12

Visual Agnosia

173
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...

Vision01:24

Vision

52.9K
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 System

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...

End Point Prediction: Gran Plot01:07

End Point Prediction: Gran Plot

234
A Gran plot is used to predict the equivalence volume or endpoint of a potentiometric or acid-base titration without reaching the endpoint. Typically, titration data is collected as a function of the titrant's volume up to a point less than the equivalence volume and then transformed into a linear format. The straight line is extended to the x-axis, indicating the necessary titrant volume to achieve the equivalence point.
For potentiometric titration, the Gran plot is created by plotting...

    Area of Science:

    • Computer Science
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Zero-shot learning (ZSL) aims to recognize classes not seen during training by leveraging auxiliary semantic information.
    • Existing ZSL methods often align visual and semantic embeddings in isolation, neglecting crucial inter-class relationships.
    • This limitation hinders the learning of robust embedding spaces and accurate recognition of unseen classes.

    Purpose of the Study:

    • To propose a novel Visual-Semantic Graph Matching Network (VSGMN) for enhanced zero-shot learning.
    • To address the limitations of existing methods by incorporating inter-class relationships into the visual-semantic alignment process.
    • To improve the performance of ZSL models in both conventional and generalized ZSL (GZSL) settings.

    Main Methods:

    • VSGMN employs a two-stage alignment process using a Graph Build Net (GBN) and a Graph Matching Net (GMN).
    • GBN builds initial visual and semantic graphs, aligning embeddings with prototypes and incorporating unseen class nodes based on semantic relationships.
    • GMN refines alignment by integrating neighbor and cross-graph information, enforcing class relationship constraints.

    Main Results:

    • Extensive experiments on three benchmark datasets demonstrate the effectiveness of VSGMN.
    • VSGMN achieves superior performance compared to existing methods in both conventional and generalized ZSL (GZSL) scenarios.
    • The proposed method successfully leverages semantic relationships for improved visual-semantic embedding.

    Conclusions:

    • The Visual-Semantic Graph Matching Network (VSGMN) offers a significant advancement in zero-shot learning.
    • Incorporating class relationships into the alignment process is crucial for robust visual-semantic embedding.
    • VSGMN provides a promising approach for recognizing unseen classes in complex scenarios.
