Há 21 horas · Mr Wilson was last seen close to where the taxi dropped him off, before seemingly vanishing. His personal belongings were found in his room. His distraught family launched a Facebook group, ...
Há 21 horas · Low-lying tropical island nations were expected to be early victims of rising seas. But research tells a surprising story: Many islands are stable. Some have even grown.
Há 21 horas · The vanishing gradients problem is one example of the unstable behaviour of a multilayer neural network. Networks are unable to backpropagate the gradient information to the input layers of the model. In a multi-layer network, gradients for deeper layers are calculated as products of many gradients (of activation functions).
Há 5 dias · What are exploding gradients and vanishing gradients? A. Exploding gradients occur when model gradients grow uncontrollably during training, causing instability. Vanishing gradients happen when gradients shrink excessively, hindering effective learning and updates.
Há 1 dia · Abstract. Various vanishing coefficient results on q -series expansions have been widely studied by many authors in recent years. Motivated by these works, we establish a general vanishing coefficient result on odd powers of Ramanujan’s theta functions.
Há 2 dias · Research suggests that both applicants and organizations may withdraw from the recruitment and selection process without notice. This behaviour, referred to as ‘ghosting’, is prevalent yet empirical ...
Há 21 horas · The aesthetic and historical significance of art is well recognized; art can stoke emotions, invite close inquiry, and connect us to the past. However, works of art are also complex material objects that present unique challenges and opportunities for the scientific community. Identifying “fugitive” organic pigments in traditional oil paintings, for example, presents a particularly complex ...
