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...

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...

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...

Improving Translational Accuracy

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Cerebrospinal Fluid

Cerebrospinal Fluid

Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....

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...

Area of Science:

Artificial Intelligence
Machine Learning
Data Science

Background:

Machine learning and AI advancements are hindered by data silos and privacy regulations.
Federated learning (FL) enables distributed model training without direct data sharing.
Current FL frameworks are often specialized, require programming expertise, and lack a central platform.

Purpose of the Study:

To develop FeatureCloud, an all-in-one platform for federated learning.
To address the gap in generic, user-friendly FL solutions for researchers.
To make FL accessible for both algorithm developers and users without programming knowledge.

Main Methods:

FeatureCloud utilizes a global frontend, global backend, and local controller architecture.
Docker is employed to containerize local components, ensuring separation from sensitive data.
The platform was evaluated using four algorithms across five datasets, assessing accuracy and runtime.

Main Results:

FeatureCloud simplifies the execution of multi-institutional FL analyses and algorithm implementation.
An integrated AI store allows for easy publishing and reuse of federated algorithms.
The platform supports privacy-enhancing technologies and complies with GDPR, producing results comparable to centralized methods.

Conclusions:

FeatureCloud integrates FL algorithm development and execution, minimizing complexity and infrastructure hurdles.
The platform significantly enhances accessibility for privacy-preserving, distributed data analyses in biomedicine and other fields.
