چکیده
Flash floods in the Eastern Mediterranean (EM) region are considered among most destructive natural hazards, which pose a significant challenge to model due their high complexity. Machine learning (ML) methods have made contribution advancement of flash flood prediction systems by providing cost-effective solutions with improved performance, enabling modeling complex mathematical expressions underlying physical processes floods. Thus, development ML for holds potential mitigate risks, inform policy recommendations, minimize loss human life, and reduce property damage caused Here, we present novel approach improving predictions EM using Support Vector Machines (SVMs) combination precipitable water vapor (PWV) data, derived from ground-based global navigation satellite system (GNSS) receivers, along surface pressure measurements, nearby lightning occurrence data predict an arid EM. The SVM was trained on historical 2004 2019 used forecast likelihood region. study found that integrating other variables significantly accuracy compared only PWV measurements. results were validated observed events, predictive area under receiver operating characteristic curve 0.93 test set. provides valuable insights into utilizing meteorological forecasting

Estimation and Analysis of Precipitable Water Vapor Using GPS Data and Satellite Altimeter
Determination of water vapor in the atmosphere plays an important role in forecasting weather conditions and precipitation studies. For this reason, it is very important to study the tropospheric delay, especially the wet component, which is due to the presence of water vapor in the atmosphere. In this paper, the amount of water vapor was estimated by altimeter satellite radiometer and GPS data...
متن کاملSTAGE-DISCHARGE MODELING USING SUPPORT VECTOR MACHINES
Establishment of rating curves are often required by the hydrologists for flow estimates in the streams, rivers etc. Measurement of discharge in a river is a time-consuming, expensive, and difficult process and the conventional approach of regression analysis of stage-discharge relation does not provide encouraging results especially during the floods.

متن کاملPredicting Nucleolar Proteins Using Support-Vector Machines
The intra-nuclear organisation of proteins is based on possibly transient interactions with morphologically defined compartments like the nucleolus. The fluidity of trafficking challenges the development of models that accurately identify compartment membership for novel proteins. A growing inventory of nucleolar proteins is here used to train a support-vector machine to recognise sequence feat...
متن کاملPredicting Time Series with Support Vector Machines
Support Vector Machines are used for time series prediction and compared to radial basis function networks. We make use of two diierent cost functions for Support Vectors: training with (i) an insensitive loss and (ii) Huber's robust loss function and discuss how t o c hoose the regularization parameters in these models. Two applications are considered: data from (a) a noisy (normal and uniform...
