Associative Learning01:27

Associative Learning

572
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...

Introduction to Learning01:18

Introduction to Learning

530
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...

Observational Learning01:12

Observational Learning

311
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...

Natural and Artificial Concepts

265
In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Generalization, Discrimination, and Extinction01:24

Generalization, Discrimination, and Extinction

785
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Cognitive Learning01:21

Cognitive Learning

517
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...

    Área de la Ciencia:

    • Ciencias de la computación
    • Inteligencia artificial
    • Aprendizaje automático

    Sus antecedentes:

    • El aprendizaje composicional de tiro cero (CZSL) se enfrenta a desafíos en el modelado de interacciones atributo-objeto y atributo-objeto.
    • El modelado preciso es crucial para reconocer conceptos invisibles formados por componentes conocidos.

    Objetivo del estudio:

    • Para abordar el problema de modelado de la interacción en CZSL.
    • Proponer una nueva red condicional de doble flujo (DSCNet) para mejorar el rendimiento de CZSL.

    Principales métodos:

    • DSCNet aprende conceptos condicionales de doble flujo, generando incorporaciones visuales y semánticas condicionales para atributos y objetos.
    • Un flujo semántico codifica la semántica del objeto / atributo y las características de la imagen, creando incrustaciones semánticas condicionales a través de un codificador cruzado.
    • Una corriente visual genera incorporaciones visuales condicionales mediante la integración de características semánticas en las características visuales.

    Principales resultados:

    • El método DSCNet propuesto demuestra un rendimiento superior con respecto a los parámetros de referencia CZSL estándar.
    • Los resultados experimentales validan la eficacia del enfoque de aprendizaje condicional de doble flujo.

    Conclusiones:

    • La DSCNet modela efectivamente las interacciones atributo-objeto y atributo-objeto en CZSL.
    • La estrategia de incorporación condicional propuesta avanza significativamente el estado de la técnica en el aprendizaje de composición de tiro cero.
