Associative Learning01:27

Associative Learning

778
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...

Nucleic Acid Structure

7.7K
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms  a 5′ to 3′ phosphodiester linkage.

Viral Structure

69.0K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Observational Learning01:12

Observational Learning

520
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...

Introduction to Learning01:18

Introduction to Learning

658
Learning is the process of acquiring knowledge or skills through practice or experience, leading to long-lasting behavioral changes. This acquisition occurs through interaction with the environment and requires practice or experience. For instance, mastering a skill such as surfing requires considerable practice and experience, highlighting the essential role of repeated interactions with the environment in learning.
In contrast to learned behaviors, unlearned behaviors such as crying, sexual...

Structure of a Gene

14.5K
A gene is the fundamental unit of heredity. Every individual has two copies of each gene, one inherited from each parent. Although most people contain the same genes, there is a small fraction that is slightly different amongst people. A gene with a small difference in its sequence of DNA bases forms different alleles, contributing to different phenotypes.
However, only 1% of the DNA is composed of genes that encode proteins; the rest, 99% is non-coding DNA. This non-coding DNA performs...

    Area of Science:

    • Computer Science
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Zero-shot learning (ZSL) faces challenges like semantic gap, domain shift, and hubness.
    • Existing methods struggle to bridge the gap between visual and semantic feature spaces.

    Purpose of the Study:

    • To propose a structure-aligned generative adversarial network (ZSL) framework.
    • To mitigate semantic gap, domain shift, and hubness problems in ZSL.
    • To improve classification performance on unseen classes.

    Main Methods:

    • A generative adversarial network (GAN) generates pseudo-visual features.
    • A softmax classifier increases interclass distance and reduces intraclass distance.
    • A structure-aligned module learns consistency between visual and semantic spaces.

    Main Results:

    • The framework effectively bridges the semantic gap by aligning visual-semantic spaces.
    • Domain shift and hubness problems are mitigated.
    • Classification performance is significantly improved for unseen classes in both conventional and generalized ZSL settings.

    Conclusions:

    • The proposed framework offers a robust solution for ZSL.
    • It successfully reformulates ZSL as a supervised task using generated features.
    • Experimental results validate its superiority over state-of-the-art methods.
