Daily Runoff Forecasting Model Based on ANN and Data Preprocessing Techniques
There are many models that have been used to simulate the rainfall-runoff relationship. The artificial neural network (ANN) model was selected to investigate an approach of improving daily runoff forecasting accuracy in terms of data preprocessing. Singular spectrum analysis (SSA) as one data preprocessing technique was adopted to deal with the model inputs and the SSA-ANN model was developed. ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولTown trip forecasting based on data mining techniques
In this paper, a data mining approach is proposed for duration prediction of the town trips (travel time) in New York City. In this regard, at first, two novel approaches, including a mathematical and a statistical approach, are proposed for grouping categorical variables with a huge number of levels. The proposed approaches work based on the cost matrix generated by repetitive post-hoc tests f...
متن کاملDaily Runoff Forecasting using Artificial Neural Network
Rainfall-Runoff is the most important hydrological variables used in most of the water resources applications. Watershed based planning and management requires thorough understanding hydrological process and accurate estimation of runoff. An Artificial Neural Network (ANN) methodology was employed to forecast daily runoff for the Kadam watershed of G-5 sub-basin of Godavari river basin. On the ...
متن کاملA hybrid model based on data preprocessing for electrical power forecasting
Electrical power forecasting plays a vital role in power system administration and planning. Inaccurate forecasting can lead to the waste of scarce energy resources, electricity shortages, and even power grid collapses. On the other hand, accurate electricity power forecasting can enable reliable guidance for the planning of power production and the operation of a power system, which is also im...
