smile.datasets.Puma8NH
Record Components:
data - data frame.
formula - modeling formula.
public record Puma8NH(DataFrame data, Formula formula) extends Record
Pumadyn dataset. This is one of dataset family synthetically generated from a realistic simulation of the dynamics of an Unimation Puma 560 robot arm. The task is to predict the angular acceleration of one of the robot arm's links. The inputs include angular positions, velocities and torques of the robot arm.
