• Abstract summary: We provide a framework for the fusion of n number of information sources using the evidence theory. We provide a methodology for the information fusion of two primary sources: an ensemble classifier based on machine data and an expert-centered model. We address the problem of data drift by proposing a methodology to update the data-based models using an evidence theory approach.

• Abstract: We propose a novel methodology to define assistance systems that rely on information fusion to combine different sources of information while providing an assessment. The main contribution of this paper is providing a general framework for the fusion of n number of information sources using the evidence theory. The fusion provides a more robust prediction and an associated uncertainty that can be used to assess the prediction likeliness. Moreover, we provide a methodology for the information fusion of two primary sources: an ensemble classifier based on machine data and an expert-centered model. We demonstrate the information fusion approach using data from an industrial setup, which rounds up the application part of this research. Furthermore, we address the problem of data drift by proposing a methodology to update the data-based models using an evidence theory approach. We validate the approach using the Benchmark Tennessee Eastman while doing an ablation study of the model update parameters.

  Modern ML systems increasingly augment input instances with additional relevant information to enhance final prediction. We study such models with two components: 1) a em retriever to identify the relevant information out of a large corpus via a data-dependent metric; and 2) a em predictor that consumes the input instances along with the retrieved information to make the final predictions.

• Federated Learning with Projected Trajectory Regularization [65.6266768678291]
  Federated learning enables joint training of machine learning models from distributed clients without sharing their local data. One key challenge in federated learning is to handle non-identically distributed data across the clients. We propose a novel federated learning framework with projected trajectory regularization (FedPTR) for tackling the data issue.

  We propose incorporating uncertainty estimation into the MNER task, producing trustworthy predictions. Our proposed algorithm models the distribution of each modality as a Normal-inverse Gamma distribution, and fuses them into a unified distribution. Experiments on two datasets demonstrate that our proposed method outperforms the baselines and achieves new state-of-the-art performance.

  Generalizing the application of machine learning models to situations where the statistical distribution of training and test data are different has been a complex problem. We introduce an anchored-based Out of Distribution (OOD) Regression Mixup algorithm, leveraging manifold hidden state mixup and observation similarities to form a novel regularization penalty. We demonstrate with an extensive evaluation the generalization performance of the proposed method against existing approaches, then show that our method achieves state-of-the-art performance.

  In this paper, we encode the neighborhood information with a graph-induced Gaussian distribution, and propose to integrate the two types of information with a graph-driven generative model. Under the approximation, we prove that the training objective can be decomposed into terms involving only singleton or pairwise documents, enabling the model to be trained as efficiently as uncorrelated ones.

  This paper proposes an interpretable non-model sharing collaborative data analysis method as one of the federated learning systems. By centralizing intermediate representations, which are individually constructed in each party, the proposed method obtains an interpretable model. Numerical experiments indicate that the proposed method achieves better recognition performance for artificial and real-world problems than individual analysis.
