Machine learningand data mining. The activation function of a node in an artificial neural network is a function that calculates the output of the node based on its individual inputs and their weights. Nontrivial problems can be solved using only a few nodes if the activation function is nonlinear. [ 1]
Situational awareness is important for effective decision making in many environments. It is formally defined as: “the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future”.
A ground proximity warning system ( GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness and warning system (TAWS). [ 1] More advanced systems, introduced in 1996, [ 2] are ...
The activation-synthesis hypothesis, proposed by Harvard University psychiatrists John Allan Hobson and Robert McCarley, is a neurobiological theory of dreams first published in the American Journal of Psychiatry in December 1977. The differences in neuronal activity of the brainstem during waking and REM sleep were observed, and the hypothesis ...
Neuroscience of sleep. The neuroscience of sleep is the study of the neuroscientific and physiological basis of the nature of sleep and its functions. Traditionally, sleep has been studied as part of psychology and medicine. [ 1] The study of sleep from a neuroscience perspective grew to prominence with advances in technology and the ...
Hard problem of consciousness. In the philosophy of mind, the hard problem of consciousness is to explain why and how humans and other organisms have qualia, phenomenal consciousness, or subjective experience. [ 1][ 2] It is contrasted with the "easy problems" of explaining why and how physical systems give a (healthy) human being the ability ...
Enter: cognitive shuffling, a method that's going viral as a "hack" for dozing off quicker. It's perfect for when you have a million racing thoughts—like how you're going to get the kids to ...
The activating function is a mathematical formalism that is used to approximate the influence of an extracellular field on an axon or neurons. It was developed by Frank Rattay and is a useful tool to approximate the influence of functional electrical stimulation (FES) or neuromodulation techniques on target neurons.
