Method Detail

getModel

public MODEL_CLASS getModel()

setModel

protected void setModel(MODEL_CLASS model)

predict

public abstract Float predict(Float inputs)

Specified by:

predict in interface Regressor<Float,Float>

getSlope

public abstract float getSlope()

How much on average output change when input changes by one. If it is zero there is no linear dependency between input and output, and data is probably scattered. If it is less then one output grows slower then input. If it is greater than one, then output is growing faster than input. If its negative, then output is lowering as input grows.

Returns:

getIntercept

public abstract float getIntercept()

The value of output when input is zero

Returns:
