Description Usage Arguments Details Value References See Also Examples

A function to build prediction model using Accelerated Gradient Descent (AGD) method.

1	AGD(dataTrain, alpha = 0.1, maxIter = 10, momentum = 0.9, seed = NULL)

`dataTrain`	a data.frame that representing training data (m \times n), where m is the number of instances and n is the number of variables where the last column is the output variable. dataTrain must have at least two columns and ten rows of data that contain only numbers (integer or float).
`alpha`	a float value representing learning rate. Default value is 0.1
`maxIter`	the maximal number of iterations.
`momentum`	a float value represent momentum give a constant speed to learning process.
`seed`	a integer value for static random. Default value is NULL, which means the function will not do static random.

This function based on SGD and MGD with optimization to accelerate the learning with momentum constant in each iteration.

a vector matrix of theta (coefficient) for linear model.
