We simulate the stochastic process of incomplete data collection to construct an incomplete COFadsorption-property matrix A (θ) (still M = 560 × P = 16) with a fraction θ of missing entries. We construct A (θ) by (uniform) randomly sampling, without replacement, (1 -θ)MP entries to ablate (change to missing) from the MP entries of A complete . Fig. visualizes a resulting incomplete COF-adsorption-property matrix A (0.4) with a fraction θ = 0.4 missing entries.
