“…With the successful introduction of machine learning algorithms from artificial intelligence science in dendrochronological studies, reconstruction methods have been extended and improved in recent years Jevšenak and Levanič, 2016). In particular, the nonparametric methods such as Long Short-Term Memory (LSTM) (Nasreen et al, 2021;Zhang et al, 2022), Random Forest (RF) Zhao et al, 2022) and Artificial Neural Network (ANN) (Salehnia & Ahn, 2022;Zhang et al, 2000) algorithms have been applied to overcome the limitations of traditional linear models bring higher accuracy and extensibility. Nevertheless, their application of nonparametric methods is restrictive, and the single algorithm is not universally applicable in every tree ring reconstruction.…”
