  14. def stopWhen(b: NetParams, sse: Double): (NetParams, Double)

    Stop when too many steps have the cost measure (e.g., sse) increasing.

    Stop when too many steps have the cost measure (e.g., sse) increasing. Signal a stopping condition by returning the best parameter vector, else null.

    b

    the current parameter value (weights and biases)

    sse

    the current value of cost measure (e.g., sum of sqaured errors)

  15. def stopWhen(b: VectoD, sse: Double): (VectoD, Double)

    Stop when too many steps have the cost measure (e.g., sse) increasing.

    Stop when too many steps have the cost measure (e.g., sse) increasing. Signal a stopping condition by returning the best parameter vector, else null.

    b

    the current value of the parameter vector

    sse

    the current value of cost measure (e.g., sum of sqaured errors)
