Description copied from interface: ReduceFunction

The core method of ReduceFunction, combining two values into one value of the same type. The reduce function is consecutively applied to all values of a group until only a single value remains.

Specified by:

reduce in interface ReduceFunction<Tuple2<LinearRegression.Params,Integer>>

Parameters:

val1 - The first value to combine.

val2 - The second value to combine.

Returns:

The combined value of both input values.
