Improving COVID-19 Forecasting using eXogenous Variables

1 code implementation20 Jul 2021 Mohammadhossein Toutiaee, Xiaochuan Li, Yogesh Chaudhari, Shophine Sivaraja, Aishwarya Venkataraj, Indrajeet Javeri, Yuan Ke, Ismailcem Arpinar, Nicole Lazar, John Miller

We demonstrate significant enhancement in the forecasting accuracy for a COVID-19 dataset, with a maximum improvement in forecasting accuracy by 64. 58% and 59. 18% (on average) over the GCN-LSTM model in the national level data, and 58. 79% and 52. 40% (on average) over the GCN-LSTM model in the state level data.

Occupancy Detection in Room Using Sensor Data

no code implementations10 Jan 2021 Mohammadhossein Toutiaee

With the advent of Internet of Thing (IoT), and ubiquitous data collected every moment by either portable (smart phone) or fixed (sensor) devices, it is important to gain insights and meaningful information from the sensor data in context-aware computing environments.

Gaussian Function On Response Surface Estimation

no code implementations4 Jan 2021 Mohammadhossein Toutiaee, John Miller

We utilize a Gaussian process as a surrogate to capture the response surface of a complex model, in which we incorporate two parts in the process: interpolated values that are modeled by a stationary Gaussian process Z governed by a prior covariance function, and a mean function mu that captures the known trends in the underlying model.

Stereotype-Free Classification of Fictitious Faces

no code implementations29 Apr 2020 Mohammadhossein Toutiaee, Soheyla Amirian, John A. Miller, Sheng Li

The proposed approach aids labeling new data (fictitious output images) by minimizing a penalized version of the least squares cost function between realistic pictures and target pictures.
