Method Detail

getLambda

public double getLambda()

The lambda is the regularisation strength.

Returns:

the lambda factor.

setLambda

public void setLambda(double lambda)

evaluate

public void evaluate(GeneralTask t)

Description copied from class: SumOfSquares

Calculates the sum of squared deviations using curve as reference.

This calculates $\sum _{i=i_1}^{i_2}\left(\overbrace{T}\right(t_i)-T(t_i{)}^{ref}{)}^2$, where $T_i^{ref}$ is the temperature value corresponding to the time at index i for the reference curve. Note that the time $t_i$ corresponds to the reference's time list, which generally does not match to that of this heating curve. The $\overbrace{T}\left(t_i\right)$ is the interpolated value.

Overrides:

evaluate in class SumOfSquares

Parameters:

t - The task containing the reference and calculated curves

getDescriptor

public String getDescriptor()

Description copied from class: PropertyHolder

If not null, will return the prefix, otherwise calls the superclass method.

Overrides:

getDescriptor in class SumOfSquares

Returns:

the descriptor
