- Record Components:
data
- data frame.formula
- modeling formula.
Robot arm simulation dataset. It is a realistic simulation of the forward
dynamics of an 8 link all-revolute robot arm, and the task is to predict
the distance of the end-effector from a target. The input are the angular
positions of the joints. Each instance represents a configuration of
angular positions of the joints and the resulting distance of the
end-effector from a target. The data is medium noisy and nonlinear.

Method Details
-
x
public double[][] x()Returns the sample features.- Returns:
- the sample features.
-
y
public double[] y()Returns the target values.- Returns:
- the target values.
-
toString
Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components. -
hashCode
public final int hashCode()Returns a hash code value for this object. The value is derived from the hash code of each of the record components. -
equals
Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared withObjects::equals(Object,Object)
