Si passa poi ad un Toroide facendo ruotare la circonferenza attorno ad un asse e preservandone la traccia durante il suo moto (colorata in arcobaleno). Tale animazione è intesa come strumento esemplificativo per comprendere che le considerazioni relative al caso unidimensionale possono essere ...
traj_data_poi_mining.py: 基于规则挖掘POI信息。 traj_data_labeling_semantics.py: 依据所挖掘的POI信息,为每一条训练样本和测试样本分配POI标签。 Embedding部分 embedding_geo_information.py: 用于对坐标信息进行embedding。我们测试了Skip-Gram和CBOW两种模型,最后仅使用了CBOW作为我们的模型。

a road network-aware trajectory sequence graph RTSG; (2) learning the representation of a node in RTSG with a weight-aware GNN module; (3) learning the representation of a trajectory with a BiLSTM-based module; (4) linking trajectories to users based on the embedding of each trajectory. ...
The recent breakthrough of single-cell RNA velocity methods brings attractive promises to reveal directed trajectory on cell differentiation, states transition and response to perturbations. However, the existing RNA velocity methods are often found to return erroneous results, partly due to model violati...
A point-of-interest (POI)-based representation framework, GTS [32] applies Long Short-Term Memory network to generate Graph Neural Network-based embeddings over spatial road networks. GTS improves the accuracy of the retrieved similar candidate set over [30], [31] because the embeddings of GTS...
DeepTrip is an end-to-end neural network method for understanding the underlying human mobility and modelling of the POI transitional distribution in human moving patterns. DeepTrip is proposed by Gao et al. [41] as an implementation of a trajectory embedding approach for a low dimensional repres...
