Research Field(Keyword & Summary)
  1. Application of Machine Learning to Network Intrusion Detection Systems

    We investigate the performance of a semi-supervised learning NIDS based on Adversarial Autoencoder (AAE) proposed in our earlier work through a series of detailed experiments. We demonstrate the proposed AAEbased NIDS outperforms the conventional machine learningbased NIDS method. The proposed semi-supervised NIDS based on AAE achieves high performance while it reduces the required number of labeled data samples in the training dataset, which requires costly human-labor tasks.

  2. Application of Few-Short Learning to Sevice Assuarance of LTE Networks

    To mitigate the cost and time issues, we propose a method based on few-shot learning that uses Prototypical Networks algorithm to complement the eNodeB states analysis. Using a dataset from a live LTE network consists of thousand of eNodeB, our experiment results show that the proposed technique provides high performance while using a low number of labeled data.

  3. Application of Bayesian Model for Traffic Forecast

    We propose a Bayesian model to model the relationship between the population and the network and computing resource. The parameters that govern the Bayesian network is estimated from the measurement.

  4. Trajectory Data Mining for Spatio-Temporal Human Mobility

    We propose a method to grasp the behavior of the mobility in spatio-temporal by mining the trajectory data of the mobility obtained from the GPS data to predict the future mobility of the user from frequent patterns. We apply sequential pattern mining algorithms including PrefixSpan and BIDE to obtain frequent trajectory patterns from trajectory database.
