Training, validation, and test data setsIn machine learning, a common task is the study and construction of algorithms that can learn from and make predictions on data. Such algorithms function by making data-driven predictions or decisions, through building a mathematical model from input data. These input data used to build the model are usually divided into multiple data sets. In particular, three data sets are commonly used in different stages of the creation of the model: training, validation, and test sets.
History of sound recordingThe history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods: The Acoustic era (1877–1925) The Electrical era (1925–1945) The Magnetic era (1945–1975) The Digital era (1975–present) Experiments in capturing sound on a recording medium for preservation and reproduction began in earnest during the Industrial Revolution of the 1800s.
Behavior managementBehavior management, similar to behavior modification, is a less-intensive form of behavior therapy. Unlike behavior modification, which focuses on changing behavior, behavior management focuses on maintaining positive habits and behaviors and reducing negative ones. Behavior management skills are especially useful for teachers and educators, healthcare workers, and those working in supported living communities. This form of management aims to help professionals oversee and guide behavior management in individuals and groups toward fulfilling, productive, and socially acceptable behaviors.
CaregiverA caregiver, carer or support worker is a paid or unpaid member of a person's social network who helps them with activities of daily living. Since they have no specific professional training, they are often described as informal caregivers. Caregivers most commonly assist with impairments related to old age, disability, a disease, or a mental disorder.
