Recurrence and recurrent may refer to: Disease recurrence, also called "relapse" Eternal recurrence, the concept that the universe is perpetually recurring; Historic recurrence, the repetition of similar events in history; Poincaré recurrence theorem, Henri Poincaré's theorem on dynamical systems
Fully recurrent neural networks (FRNN) connect the outputs of all neurons to the inputs of all neurons. In other words, it is a fully connected network . This is the most general neural network topology, because all other topologies can be represented by setting some connection weights to zero to simulate the lack of connections between those ...
Recurrent event analysis is a branch of survival analysis that analyzes the time until recurrences occur, such as recurrences of traits or diseases. Recurrent events are often analyzed in social sciences and medical studies, for example recurring infections, depressions or cancer recurrences.
Simple recurrent networks have three layers, with the addition of a set of "context units" in the input layer. These units connect from the hidden layer or the output layer with a fixed weight of one. [53]
Niccolò Machiavelli, analyzing the state of Florentine and Italian politics between 1434 and 1494, described recurrent oscillations between "order" and "disorder" within states: [23] when states have arrived at their greatest perfection, they soon begin to decline.
Long short-term memory (LSTM) [1] is a type of recurrent neural network (RNN) aimed at mitigating the vanishing gradient problem [2] commonly encountered by traditional RNNs. Its relative insensitivity to gap length is its advantage over other RNNs, hidden Markov models , and other sequence learning methods.
In mathematics, a recurrence relation is an equation according to which the th term of a sequence of numbers is equal to some combination of the previous terms. Often, only previous terms of the sequence appear in the equation, for a parameter that is independent of ; this number is called the order of the relation.
Recurrent evolution also referred to as repeated [1] [2] or replicated [3] evolution is the repeated evolution of a particular trait, character, or mutation. [4] Most evolution is the result of drift, often interpreted as the random chance of some alleles being passed down to the next generation and others not.
