Kurt Lewin (/ l ɛ ˈ v iː n / lə-VEEN; 9 September 1890 – 12 February 1947) was a German-American psychologist, known as one of the modern pioneers of social, organizational, and applied psychology in the United States. [1]
The 'locus' [56] of activity-based LGC is the Organization Workshop(OW), [57] a learning event where participants, applying social division of labor principles, [58] master new organizational knowledge and skills through a learning-by-doing approach. In OW-learning, the trainer's role is merely subsidiary (known as "scaffolding" in Activity ...
The word theory in "the theory of evolution" does not imply scientific doubt regarding its validity; the concepts of theory and hypothesis have specific meanings in a scientific context. While theory in colloquial usage may denote a hunch or conjecture, a scientific theory is a set of principles that explains an observable phenomenon in natural ...
Major advances in this field can result from advances in learning algorithms (such as deep learning), computer hardware, and, less-intuitively, the availability of high-quality training datasets. [1] High-quality labeled training datasets for supervised and semi-supervised machine learning algorithms are usually difficult and expensive to ...
This idea that leadership is based on individual attributes is known as the "trait theory of leadership". A number of works in the 19th century – when the traditional authority of monarchs, lords, and bishops had begun to wane – explored the trait theory at length: especially the writings of Thomas Carlyle and of Francis Galton.
It is an interdisciplinary field spanning computer science, psychology, and cognitive science. [1] While some core ideas in the field may be traced as far back as to early philosophical inquiries into emotion , [ 2 ] the more modern branch of computer science originated with Rosalind Picard 's 1995 paper entitled "Affective Computing" [ 3 ] and ...
An example of experience curve effects: Swanson's law states that solar module prices have dropped about 20% for each doubling of installed capacity. [1] [2]In industry, models of the learning or experience curve effect express the relationship between experience producing a good and the efficiency of that production, specifically, efficiency gains that follow investment in the effort.
In the adaptive control literature, the learning rate is commonly referred to as gain. [2] In setting a learning rate, there is a trade-off between the rate of convergence and overshooting. While the descent direction is usually determined from the gradient of the loss function, the learning rate determines how big a step is taken in that ...
