Learning sequence

A learning model (hereinafter, the Model) is any model that conceptualizes the process of one's learning.

Onboarding

Onboarding (hereinafter, the Process) is the process and/or the learning model that depicts that process of either:

Integrating a new employee into an organization including helping this employee to adapt to the organization's culture (this process is more specifically known as organizational socialization, socialization process, or, simply, socialization); or
Familiarizing a new customer or client with one's products or services.

Those Models that emphasize learning through cognition are known as cognitive development. The Piaget's theory of cognitive development (alternatively known as theory of cognitive development and partially known as mental-model development) is probably still the most popular among those models.

Artificial neural network (ANN). The Model based on the biological neural networks present in the brains of animals. Based on the activity of neurons, ANNs are used to solve tasks that would be too difficult for traditional methods of programming.
Social learning
Social learning. The process of learning from the others.
