Objective

Find a mapping $DS$ (cumulative downsampler) such that $$DS : {X} \longrightarrow {Y} \times {R}, \quad where \quad {X} = \mathbb{R}^N, \quad {Y} = \mathbb{R}^M, \quad M \le N,\quad N \gt 1, \quad M \gt 1 \quad \text{and} \quad M \text{ is a cost to minimize.}$$

$DS$ has these constraints:

1. $\exists {m} in {M} \text{such that } Increase(X) = Increase(D(X)) ; \text{for all } x \in X$
   • The increase observed in the input and output must be equal
2. $\forall x \in X, ; y = DS(x) ; => y_1 = x_1 ; and ; y_m = x_n$
