Spatial mismatch and congruence in the taxonomic, functional, and phylogenetic diversities of fish assemblages in China's water diversion lakes by Zhice Liang, Rodolphe Elie Gozlan, Chenyi Kuang, Jiashou Liu, Chuanbo Guo

“…Our results revealed that: 1) fish diversity and community assembly showed no longitudinal gradient, with spatial mismatches across diversity dimensions; 2) functional diversity was negatively correlated with both taxonomic and phylogenetic diversities, while the latter two showed no correlation; and 3) the SNWDP primarily affected taxonomic and functional diversities by altering water depth, nutrient status and promoting non-native species invasion, while phylogenetic diversity was mainly influenced by changes in water temperature and dissolved oxygen. …”

Development of the algal pigment-based salinity transfer function for lakes on the Tibetan Plateau and evaluation of the quantitative reconstruction by Xinyao Sun, Qi Lin, Chenliang Du, Shixin Huang, Ke Zhang, Ji Shen

“…Salinity was considered as the most important factor determining the distribution pattern of pigment assemblage, and pigment concentrations differed significantly along the lake salinity gradient. Nine chlorophyll, xanthophyll and carotenoid pigments were comprehensively assessed to develop the pigment-salinity transfer function. …”

Actor-critic algorithm with incremental dual natural policy gradient by Peng ZHANG, Quan LIU, Shan ZHONG, Jian-wei ZHAI, Wei-sheng QIAN

“…The existed algorithms for continuous action space failed to consider the way of selecting optimal action and utilizing the knowledge of the action space,so an efficient actor-critic algorithm was proposed by improving the natural gradient.The objective of the proposed algorithm was to maximize the expected return.Upper and the lower bounds of the action range were weighted to obtain the optimal action.The two bounds were approximated by linear function.Afterward,the problem of obtaining the optimal action was transferred to the learning of double policy parameter vectors.To speed the learning,the incremental Fisher information matrix and the eligibilities of both bounds were designed.At three reinforcement learning problems,compared with other representative methods with continuous action space,the simulation results show that the proposed algorithm has the advantages of rapid convergence rate and high convergence stability.…”

Convergence Rates of Gradient Methods for Convex Optimization in the Space of Measures by Chizat, Lénaïc

“…Under basic regularity assumptions, we show that the suboptimality gap at iteration $k$ is in $O(\log (k)k^{-1})$ for multiplicative updates, while it is in $O(k^{-q/(d+q)})$ for additive updates for some $q\in \lbrace 1,2,4\rbrace $ determined by the structure of the objective function. Our flexible proof strategy, based on approximation arguments, allows us to painlessly cover all Bregman Proximal Gradient Methods (PGM) and their acceleration (APGM) under various geometries such as the hyperbolic entropy and $L^p$ divergences. …”
