Details of the hypergraph:
Center hyperedge (induced by source paper "an efficient and effective second order training algorithm for lstm based adaptive learning"):
  Abstract: We study the problem of adaptive (or online) nonlinear regression with long short term memory (LSTM) based networks, i.e., LSTM-based adaptive learning. For the LSTM-based adaptive learning, we introduce a highly efficient and effective extended Kalman filter (EKF) based training algorithm. Our algorithm is truly online, i.e., it does not make any assumption on the underlying data generating process and future information such as the data length or data change statistics. Through an extensive set of simulations, we demonstrate significant performance improvements achieved by our algorithm with respect to the widely used LSTM training methods in the adaptive learning and machine learning literatures. We particularly show that our algorithm provides very similar error performance with the EKF learning algorithm in 9 to 38 times shorter training time depending on the parameter size of the network.
