Multi-input and Multi-variable systems

273
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

Observational Learning01:12

Observational Learning

655
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...

Associative Learning01:27

Associative Learning

895
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 Learning

717
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...

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

308
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...

Area of Science:

  • Computer Science
  • Artificial Intelligence
  • Machine Learning

Background:

  • Convolutional Neural Networks (CNNs) are vital deep learning models requiring extensive labeled data for optimal performance.
  • Manual data labeling is labor-intensive and time-consuming, posing a significant bottleneck in CNN development.
  • Active learning strategies aim to minimize labeling effort by intelligently selecting data points for annotation.

Purpose of the Study:

  • To propose a novel intelligent active learning method, Multi-View Active Learning based on Double-Branch Network (MALDB), for deep learning.
  • To enhance the efficiency of training Convolutional Neural Networks (CNNs) by reducing the need for large labeled datasets.
  • To improve classifier performance through iterative expansion of the training dataset using strategically selected unlabeled samples.

Main Methods:

  • MALDB integrates two Bayesian Convolutional Neural Networks (BCNNs) with distinct structures as dual branches within a classifier.
  • The method analyzes unlabeled datasets, querying informative samples based on the divergent characteristics learned by the two BCNN branches.
  • It leverages multi-level feature information from various hidden layers of the BCNNs to ensure stable sample selection.

Main Results:

  • Experimental validation was performed on five diverse datasets: Fashion-MNIST, Cifar-10, SVHN, Scene-15, and UIUC-Sports.
  • The proposed MALDB method demonstrated significant effectiveness in improving classifier performance.
  • Results confirmed the validity and efficiency of the MALDB approach in active learning for deep learning.

Conclusions:

  • The Multi-View Active Learning based on Double-Branch Network (MALDB) effectively reduces the dependency on large labeled datasets for training deep learning models.
  • MALDB enhances classifier performance and stability by intelligently querying and incorporating informative samples.
  • This approach offers a promising solution for efficient model training in domains where data labeling is a constraint.
