A Novel Hybrid System of Detecting Brain Tumors in MRI

open access: yesIEEE Access, 2023
The growth of irregular brain cells leads to a disease called brain tumor (BT). It is difficult to predict a patient’s chance of survival due to the low rate and wide range of tumor shapes.

Improving Hybrid Models for Precipitation Forecasting by Combining Nonlinear Machine Learning Methods

open access: yesWater resources management, 2021
Precipitation forecast is key for water resources management in semi-arid climates. The traditional hybrid models simulate linear and nonlinear components of precipitation series separately. But they do not still provide accurate forecasts. This research

Developing RNN-T Models Surpassing High-Performance Hybrid Models with Customization Capability [PDF]

open access: yesInterspeech, 2020
Because of its streaming nature, recurrent neural network transducer (RNN-T) is a very promising end-to-end (E2E) model that may replace the popular hybrid model for automatic speech recognition. In this paper, we describe our recent development of RNN-T

Hybrid RANS/LES of plane impinging jets with k-omega based models [PDF]

open access: yes, 2010
Plane impinging jets with nozzle-plate distances H/B=10 at Re=13500 and H/B=9.2 at Re=20000 are simulated with k-omega based hybrid RANS/LES models. Three ways of substitution of the turbulent length scale by the local grid size in the LES mode of the ...
