Learning Disabilities

421
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

What are Estimates?

7.5K
It isn't easy to measure a parameter such as the mean height or the mean weight of a population. So, we draw samples from the population and calculate the mean height or mean weight of the individuals in the sample. This sample data acts as a representative measure of the population parameter. These sample statistics are known as estimates. 
The estimate for the mean of a sample is denoted by ͞x, whereas the mean of the population is designated as μ. Further, parameters such...

The Availability Heuristic01:08

The Availability Heuristic

6.8K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Purposive Learning01:22

Purposive Learning

302
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...

Associative Learning01:27

Associative Learning

882
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 Learning01:21

Cognitive Learning

852
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...

Area of Science:

  • Artificial Intelligence
  • Machine Learning
  • Natural Language Processing

Background:

  • Curriculum learning (CL) commonly uses heuristics for example difficulty and model ability estimation.
  • This approach can be suboptimal, limiting training efficiency and model performance.

Purpose of the Study:

  • To replace heuristic-based difficulty estimation with learned parameters in CL.
  • To introduce Dynamic Data selection for Curriculum Learning via Ability Estimation (DDaCLAE) for adaptive training.
  • To evaluate the effectiveness of these novel CL strategies.

Main Methods:

  • Implemented learned difficulty parameters to replace heuristic estimations.
  • Developed DDaCLAE, a method probing model ability each epoch for dynamic data selection.
  • Trained and evaluated models on the GLUE benchmark for classification tasks.

Main Results:

  • Models utilizing learned difficulty parameters showed improved performance over heuristic CL.
  • DDaCLAE strategy further enhanced training by adapting data selection to model ability.
  • Both learned difficulty and DDaCLAE individually and combined outperformed baseline CL methods.

Conclusions:

  • Learned difficulty parameters offer a more effective alternative to heuristic-based CL.
  • DDaCLAE provides a dynamic and adaptive approach to data selection in CL.
  • These methods represent significant advancements in optimizing model training for classification tasks.
