Type: Bachelor Master UROP
GANs are a type of neural networks that once trained on a specific dataset, they can generate new samples, similar but not same, as the samples in the training dataset (e.g., see 15). This generative characteristic can be used to generate human mobility trajectories, and thus enhance existing labeled human mobility datasets, in order to improve the performance of existing methods for human mobility modeling.
In the context of a BSc project, you will: (i) overview methods and datasets for trajectory generation (e.g., ); (ii) use an existing GAN method for trajectory generation on new datasets; (iii) compare the generated trajectories with original trajectories and analyze the behavior of the network for a variety of parameters; (iv) summarize the results and propose future work.
In the context of an MSc thesis or UROP project, you will: (i) overview methods and datasets for trajectory generation (e.g., ); (ii) pre-process datasets appropriate for the task (e.g., ); (iii) create a novel GAN method for trajectory generation; (iv) use the generated trajectories to enhance existing datasets and evaluate machine-learning models for next-task prediction on enhanced vs. original dataset; (v) summarize the results and propose future work.
