Distributionally robust stochastic optimization (DRSO) is an approach to under uncertainty in which, instead of assuming that there a known true underlying probability distribution, one hedges against chosen set distributions. In this paper, we first point out the distributions should be appropriate for application at hand and some choices have been popular until recently are, many applications, not good choices. We next consider sets are within Wasserstein distance from nominal...
Gas-fired units and power-to-gas facilities provide pivotal backups for power systems with volatile renewable generations. The deepened system interdependence calls elaborate consideration of network models both natural gas systems, as well uncertain factors. This paper proposes a data-driven distributionally robust optimization model the optimal gas-power flow problem wind generation. concept zonal line pack reserve are raised to topologically distinguish fuel suppliers gas-fired ensure...
This paper builds a bridge between two area in optimization and machine learning by establishing general connection Wasserstein distributional robustness variation regularization. It helps to demystify the empirical success of distributionally robust devise new regularization schemes for learning.
In this paper, we propose a risk-based data-driven distributionally robust approach to investigating the optimal power flow with dynamic line rating. The risk terms, including penalties for load shedding, wind generation curtailment and overload, are embedded into objective function. To robustify solution, consider distributional uncertainty set based on second-order moment, that captures correlation between outputs ratings, also Wasserstein distance, hedges against data perturbations. We...
Wasserstein distributionally robust optimization is a recent emerging modeling paradigm for decision making under data uncertainty. Because of its computational tractability and interpretability, it has achieved great empirical successes across several application domains in operations research, computer science, engineering, business analytics. Despite success, existing performance guarantees generic problems are not yet satisfactory. In this paper, we develop the first finite-sample...
We study policy optimization for the feature-based newsvendor, which seeks an end-to-end that renders explicit mapping from features to ordering decisions. Most existing works restrict policies some parametric class may suffer suboptimality (such as affine class) or lack of interpretability neural networks). Differently, we aim optimize over all functions features. In this case, classic empirical risk minimization yields a is not well-defined on unseen feature values. To avoid such...
Cardiovascular systems essentially have multiscale control mechanisms. Multiscale entropy (MSE) analysis permits the dynamic characterization of cardiovascular time series for both short-term and long-term processes, thus can be more illuminating. The traditional MSE heart rate variability (HRV) is performed on original RR interval (named as MSE_RR). In this study, we proposed an differential signal, named MSE_dRR. motivation using signal that has a direct link with inherent non-linear...
In this work, we investigate the relationship between reliability and security of a typical two-user downlink non-orthogonal multiple access (NOMA) communication system. The level successive interference cancellation on NOMA user is considered. Firstly, impact various key parameters transmit signal-to-noise ratio (SNR) users with outage probability (ROP) constraint discussed. Taking minimum SNR for ROP into account, secrecy performance systems studied analytical expressions system are...
Distributionally robust stochastic optimization (DRSO) is a framework for decision-making problems under certainty, which finds solutions that perform well chosen set of probability distributions. Many different approaches specifying distributions have been proposed. The choice matters, because it affects the results, and relative performance choices depend on characteristics problems. In this paper, we consider in random variables exhibit some form dependence, but exact values parameters...
Zero energy building (ZEB) is one of the important ways to reduce carbon emissions. Therefore, this paper proposed a new off-grid integrated system for ZEB (ZEBOIES) and its optimal scheduling strategy based on twin delayed deep deterministic policy gradient with mixed integer linear programming constrained (MC-TD3) algorithm. First, topological structure ZEBOIES described in detail, then mathematical model each component described. Second, bilateral uncertainty supply demand ZEBOIES,...
In existing breast cancer prediction research, most models rely solely on a single type of imaging data, which limits their performance. To overcome this limitation, the present study explores based multimodal medical images (mammography and ultrasound images) compares them with single-modal models. We collected data from 790 patients, including 2,235 mammography 1,348 images, conducted comparison using six deep learning classification to identify best model for constructing model....

To distinguish among mushrooms other fungi effectively accurately, as well to explore universal identification method, this study proposed method identify by Fourier Transform Infrared Spectroscopy (FT-IR) combined machine learning. In experiment, two kinds of common mushrooms, Lentinus edodes club fungi, were selected classified mushrooms. Due different distribution...
