Purposive Learning01:22

Purposive Learning

181
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...

Observational Learning01:12

Observational Learning

260
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

503
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...

Cognitive Learning

474
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...

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

Area of Science:

  • Behavioral neuroscience
  • Machine learning
  • Computer vision

Background:

  • Accurate annotation of training data for behavior analysis requires specialized knowledge, which is time-consuming for domain experts.
  • Automated behavior analysis from video tracking data faces challenges due to annotation burden.

Purpose of the Study:

  • To introduce TREBA (Trajectory Embedding for Behavior Analysis), a method for annotation-sample efficient trajectory embedding.
  • To reduce the effort of domain experts in annotating data for behavior analysis.

Main Methods:

  • TREBA utilizes multi-task self-supervised learning to learn trajectory embeddings.
  • Domain experts use "task programming" to encode structured knowledge into programmed tasks.
  • The method trades data annotation time for the creation of a small number of programmed tasks.

Main Results:

  • TREBA reduced annotation burden by up to a factor of 10 across three datasets in mice and fruit flies.
  • Accuracy was maintained compared to state-of-the-art features.
  • Experimental validation was performed using data from behavioral neuroscience.

Conclusions:

  • Task programming combined with self-supervision effectively reduces annotation effort for domain experts.
  • TREBA offers a viable solution for efficient behavior analysis in research settings.
  • The findings suggest a promising direction for leveraging expert knowledge in machine learning for scientific discovery.
