Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Implicit biases of optimization algorithms for neural networks and their effects on generalization
神经网络 优化算法 隐式偏差 泛化的影响
2023/4/26
Modern neural networks are usually over-parameterized—the number of parameters exceeds the number of training data. In this case the loss functions tend to have many (or even infinite) global minima, ...

pgRouting library provides functions to compute shortest path between any two points of a road network which is of great demand and also a topic of interest in the field of GIS, graph theory and trans...
ROAD NETWORK GENERALIZATION BASED ON FLOAT CAR TRACKING
Road network Dynamic attributes Mapping,Gathering Topology
2016/11/8
Road generalization is not only helpful to simplify complicated road networks but can also satisfy the needs of reasonable display of roads under varying scales, thus offering basis for updating and g...
DO THE VISUAL COMPLEXITY ALGORITHMS MATCH THE GENERALIZATION PROCESS IN GEOGRAPHICAL DISPLAYS?
Visual complexity feature congestion subband entropy
2016/7/8
In this study, we first develop a hypothesis that existing quantitative visual complexity measures will overall reflect the level of cartographic generalization, and test this hypothesis. Specifically...
