WebThe embedding process causes low distortion into the data considering the usability restrictions defined over the marked relation. The conducted experiments show the high resilience of the proposed technique against tuple deletion and tuple addition attacks. Weban expansive metric embedding with distortion c with the in-equality 1 ≤ d(φ(p),φ(q))/D(p,q) ≤ c. When c = 1, these two notions coincide to require exact preservation of all distances; such an embedding is called a metric embedding with no distortion or an isometric embedding. In general, c∗ = c∗(D,T ) denotes the minimum possible ...
