Rekurrentne

Rekurrentne is a Polish adjective meaning recurring, reappearing, or repeating over time. It is used across disciplines to describe phenomena or constructs that exhibit recurrence, either in time or in definitional structure. The noun form rekurencja corresponds to recurrence.

In mathematics and computer science, rekurrentne often describes objects defined by recurrence relations, where the value of a term is determined by previous terms. Recurrence relations are fundamental in generating sequences, analyzing algorithms, and solving problems via iterative computation or dynamic programming. The classic Fibonacci sequence is a simple example of a rekurrentne definition.

In artificial intelligence and neural computation, rekurrentne networks refer to systems with feedback that preserve information across steps. Recurrent neural networks process sequential data, such as text or audio, by maintaining an internal state. They are powerful for context-aware tasks but can be difficult to train because of vanishing or exploding gradients; variants such as long short-term memory (LSTM) and gated recurrent units (GRU) address these issues.

In medicine and epidemiology, rekurrentne describes events that reoccur, such as rekurrentne infections or rekurrentne episodes of a disease, after partial or temporary remission. This usage emphasizes repeated occurrence rather than a single, isolated event.
