1. São Paulo-Guarulhos International Airport

2. Gated recurrent unit

Technology & Computing · Artificial Intelligence Abbreviations

A simplified recurrent neural network cell with two gates, update and reset, that captures long-range dependencies like an LSTM with fewer parameters and faster training.

Example: Swapping the LSTM for a GRU cut training time by a quarter with no loss of accuracy.

Introduced by Kyunghyun Cho and colleagues in 2014 in work on neural machine translation. Comparisons with LSTMs are mixed and depend on the task. Like other recurrent networks, GRUs have largely been displaced by transformers for language.
