metaSVR: Support Vector Regression with Metaheuristic Algorithms Optimization

metaSVR is an R Package to integrates Support Vector Regression (SVR) with various metaheuristic algorithms for automated hyperparameter tuning which is: cost, gamma, and epsilon.

This package can be used to do prediction using SVR for either small or big dataset and to do task where required optimal performance, such as forecasting renewable energy production, forecasting air pollutant, or modelling any regression that involve nonlinear patterns.

Features provided in this package include:

Hybrid of SVR with several metaheuristic algorithms such as:
Archimedes Optimization (AO)
Coot Bird Optimization (CBO)
Combined Archimedes Optimization with Coot Bird Optimization (AOCBO)
Harris Hawks Optimization (HHO)
Grey Wolf Optimizer (GWO)
Ant Lion Optimization (ALO)
Enhanced Harris Hawks Optimization with Coot Bird Optimization (EHHOCBO)
SVR can be customized by kernel: radial, polynomial, or sigmoid
Multiple objective functions supported: sMAPE, MAPE, RMSE, MAE
Flexible hyperparameter search space for cost, gamma, and epsilon
Built-in support for min-max normalization and automatic denormalization
Outputs include best parameter set, iteration history, time used, and evaluation metrics

Features provided in this package include:

e1071 (for Support Vector Regression Modelling and Kernel)
stats (for prediction and generate random number)
hms (for calculating optimization duration)

You can install the development version of metaSVR from GitHub with:

# install.packages("devtools")
devtools::install_github("rechtianaputri/metaSVR")

Here is a simple usage example of metaSVR using synthetic data:

library(metaSVR)

#Generate synthetic data
set.seed(123)
x <- matrix(rnorm(100), ncol = 2)
y <- x[,1] * 3 + rnorm(50)

# Run SVR Hybird with AOCBO
result <- svrHybrid(x_train = x[1:40,], y_train = y[1:40],
                   x_test = x[41:50,], y_test = y[41:50],
                   kernel = "radial", optimizer = "AOCBO",
                   objective = "SMAPE", is.y.normalize = FALSE,
                   max_iter = 100, N = 40)

# Access Results
result$best_params # show the best parameter result
result$total_iter # show total iteration to optimize
result$model # SVR model optimizing by metaheuristic algorithms
result$time # Time used to generate optimization

Each metaheuristic is implemented as a standalone optimizer, used by each optimization to improve SVR. For full documentation see the help files:
