  • SIMON, an Automated Machine Learning System, Reveals Immune Signatures of Influenza Vaccine Responses.
    Journal of Immunology, 2019
    Co-Authors: Adriana Tomic, Ivan Tomic, Yael Rosenberg-hasson, Cornelia L. Dekker, Holden T. Maecker, Mark M Davis
    Abstract:

    : Machine Learning holds considerable promise for understanding complex biological processes such as vaccine responses. Capturing interindividual variability is essential to increase the statistical power necessary for building more accurate predictive models. However, available approaches have difficulty coping with incomplete datasets which is often the case when combining studies. Additionally, there are hundreds of algorithms available and no simple way to find the optimal one. In this study, we developed Sequential Iterative Modeling "OverNight" (SIMON), an automated Machine Learning System that compares results from 128 different algorithms and is particularly suitable for datasets containing many missing values. We applied SIMON to data from five clinical studies of seasonal influenza vaccination. The results reveal previously unrecognized CD4+ and CD8+ T cell subsets strongly associated with a robust Ab response to influenza Ags. These results demonstrate that SIMON can greatly speed up the choice of analysis modalities. Hence, it is a highly useful approach for data-driven hypothesis generation from disparate clinical datasets. Our strategy could be used to gain biological insight from ever-expanding heterogeneous datasets that are publicly available.

  • time series analytics using sliding window metaheuristic optimization based Machine Learning System for identifying building energy consumption patterns
    Applied Energy, 2016
    Co-Authors: Juisheng Chou, Ngoctri Ngo
    Abstract:

    Smart grids are a promising solution to the rapidly growing power demand because they can considerably increase building energy efficiency. This study developed a novel time-series sliding window metaheuristic optimization-based Machine Learning System for predicting real-time building energy consumption data collected by a smart grid. The proposed System integrates a seasonal autoregressive integrated moving average (SARIMA) model and metaheuristic firefly algorithm-based least squares support vector regression (MetaFA-LSSVR) model. Specifically, the proposed System fits the SARIMA model to linear data components in the first stage, and the MetaFA-LSSVR model captures nonlinear data components in the second stage. Real-time data retrieved from an experimental smart grid installed in a building were used to evaluate the efficacy and effectiveness of the proposed System. A k-week sliding window approach is proposed for employing historical data as input for the novel time-series forecasting System. The prediction System yielded high and reliable accuracy rates in 1-day-ahead predictions of building energy consumption, with a total error rate of 1.181% and mean absolute error of 0.026kWh. Notably, the System demonstrates an improved accuracy rate in the range of 36.8–113.2% relative to those of the linear forecasting model (i.e., SARIMA) and nonlinear forecasting models (i.e., LSSVR and MetaFA-LSSVR). Therefore, end users can further apply the forecasted information to enhance efficiency of energy usage in their buildings, especially during peak times. In particular, the System can potentially be scaled up for using big data framework to predict building energy consumption.
