چکیده
We present a fast and accurate data-driven surrogate model for divertor plasma detachment prediction leveraging the latent feature space concept in machine learning research. Our approach involves constructing training two neural networks. An autoencoder that finds proper representation (LSR) of state by compressing multi-modal diagnostic measurements, forward using multi-layer perception (MLP) projects set control parameters to its corresponding LSR. By combining decoder network from autoencoder, this new is able predict consistent measurements based on few parameters. In order ensure crucial physics correctly captured, highly efficient 1D UEDGE used generate validation data study. Benchmark between simulations shows our capable provide (usually within percent relative error margin) but with at least four orders magnitude speed-up, indicating performance-wise, it has potential facilitate integrated tokamak design control. Comparing widely two-point and/or formatting, features additional front can be easily extended incorporate richer physics. This study demonstrates complicated scrape-off-layer low-dimensional space. Understanding dynamics utilizing knowledge could open path magnetic fusion energy

متن کاملA Data-driven Method for Crowd Simulation using a Holonification Model
In this paper, we present a data-driven method for crowd simulation with holonification model. With this extra module, the accuracy of simulation will increase and it generates more realistic behaviors of agents. First, we show how to use the concept of holon in crowd simulation and how effective it is. For this reason, we use simple rules for holonification. Using real-world data, we model the...
متن کاملA Data-Driven Approach for Event Prediction
When given a single static picture, humans can not only interpret the instantaneous content captured by the image, but also they are able to infer the chain of dynamic events that are likely to happen in the near future. Similarly, when a human observes a short video, it is easy to decide if the event taking place in the video is normal or unexpected, even if the video depicts a an unfamiliar p...
متن کاملData-Driven Mortality Prediction for Trauma Patients
Trauma is the leading cause of death between the ages of 1 to 44. A large number of these deaths occur within days of the arrival of the patient at the hospital. Accurate prediction of the outcomes of trauma patients and the identification of a few key predictors would be highly valuable. In this paper we focus on (1) the prediction of mortality within any given time frame after arrival, and (2...
