An integrated autoencoder-based filter for sparse big data

We propose a novel filter for sparse big data, called an integrated autoencoder (IAE), which utilises auxiliary information to mitigate data sparsity. The proposed model achieves an appropriate balance between prediction accuracy, convergence speed, and complexity. We implement experiments on a GPS trajectory dataset, and the results demonstrate that the IAE is more accurate and robust than some state-of-the-art methods.
