Observational Learning

Observational Learning

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 Learning

Introduction to Learning

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...

Associative Learning

Associative Learning

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...

Steps in the Modeling Process

Steps in the Modeling Process

Albert Bandura's theory of observational learning identifies four critical processes: attention, retention, motor reproduction, and reinforcement or motivation.
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...

Cognitive Learning

Cognitive Learning

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...

Purposive Learning

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Background:

Static training in video activity recognition requires retraining from scratch for new classes, incurring significant data and cost challenges.
Existing methods struggle with catastrophic forgetting when introducing new classes incrementally.

Purpose of the Study:

To develop an incremental learning algorithm for video action recognition that can incorporate new classes without prior data.
To prevent catastrophic forgetting in incremental learning scenarios for action recognition.

Main Methods:

Proposes an incremental learning algorithm combining network sharing and knowledge distillation.
Introduces a neural network architecture for video data representation.
Implements feature-level (spatial and temporal) and classification-level knowledge distillation.
Suggests initializing new classifiers using parameters from previous ones.

Main Results:

The proposed algorithm successfully teaches new classes without forgetting previously learned ones.
Demonstrates effective knowledge distillation at both feature and classification levels.
Evaluated on benchmark datasets (UCF101, HMDB51, Kinetics-400) considering various factors like distillation amount and number of new classes.

Conclusions:

The developed incremental learning approach enables adaptable video action recognition systems.
Effectively mitigates catastrophic forgetting, reducing the need for retraining and prior data.
Offers a viable solution for continuously updating action recognition models with new activities.
